Anyone know about hurco kmb1 w/bx controller I have an estop problem
after I load master. Like to know how I can get around it or test it.
Thanks.

sounds like you got your master loaded, eh?...is the emergency button pressed? turn to release if it is...

does the message simply say emergency stop or does something follow that...also, what version software did you load?

Hey john, Yes the e stop is out not in. I got vers. 1.7 something. I am new to the hurcos not to cnc so here are some questions, but how do I get the machine to zero. also the spindle brake should that be on when I power up the machine, I press brake on control and hear a click but nothing, When I go to press power on it does not stay on. I can not remember if there is any more to the e stop alarm but I am sure thats all it said was emergency stop.

Iam at work not in my shop I work 2nd shift so I am planning on being up very late to see if I can get it to work. What hours you working days or nights?

do you have air supplied to the machine? (it is necessary... or you can TEMPORARILY jump the pressure switch out)...are you sure about software 1.7?...seems the master you need is like 53.50b3 or something like that...i work days...

what ended up being the master loading issue if you don't mind me asking...

yes I have air to the machine and the master is 5150b3. How do I go about doing that

Dos and some other computer mumbo jumbo. but it was dos mostly.

good so running in dos mode did help...when you hit the power on switch does the cor relay (inside the right cabinet) latch in and stay on?

no I ended up with new proms and a window system now. what is cor relay and what latch

control on relay in the cnc (right side) cabinet, and by latch in i mean does it energize and stay on...

also check for any overloads tripped in the left cabinet (usually a button labeled reset is available for the overloads)...do you have any manuals?

yes I have a operators manual it does not have much for schematics it talks more about the parajust. if I have something tripped should it be labeled from the factory
as far as a reset. also does the brake problem I wrote earlier trouble you what about it

i think that our main issue IS the emergency stop message on the screen...we have to get rid of that...then COR should come on and stay on when you hit power on button...we need to get rid of the estop...check the overloads...the brake will not come on without the COR being energized\latched, the click you hear is the brake relay trying to work, but without COR it cannot operate properly...look for small buttons near the three phase contactors in the left-side cabinet and push them in...

Thanks John I will give it a try tonight. When you say the "the brake will not come on without the COR being energized\latched, the click you hear is the brake relay trying to work, but without COR it cannot operate properly" do you mean That the spindle brake should not be on, because when I fire the compressor up and as the machine gets more psi the spindle brake is on I can not turn the spindle is that the way it is even before I turn the main power switch on left cabinet.

the brake is normally on (pneumatically\mechanically) with the air pressure on, so i guess a better way of saying it is that the brake relay in the cnc cabinet turns on when the brake button is pushed, which applies the voltage to the brake solenoid which then operates\releases the brake cylinder allowing the spindle to then turn freely...but the brake relay does not have the voltage supplied by the cor relay due to our problem with the emergency stop message...

Well John, It ended up being the air switch stuck or just plain dirty. I took it apart and cleaned up a bit and got it. So I went to zero table and as you stand in front of machine it went in x to the right in y went back but the motion error. There is a small piece of coollant line that was behind the table, I thought thats were it was supposed to go since thats were it was. so my question to you is how can I manually back off the y axis some to remove the hose. Hope you got some suggestions!!

Well I ended up removing the encoder and manually moved table and that worked. THANKS.

sounds like you are up and going...good deal

yep and tonight I plan on playing around on it to learn as much as I can. Again THANKS
ALOT.

Well, have a problem, I wrote a small program from the book and It seems that when spindle on and I am jogging one of the axis I get a motion error. Now I can jog all axis just fine, but when I go to start the spindle it just does not sound right, how tight should I have the spindle belt, right now I have it pretty tight. Do you think that could drag spindle or the brake or the one thing I dont want is need more power.

does the spindle sound like it is cogging? in the left cabinet (parajust\magnetics cabinet) there are six parajust driver boards (all the same boards, three on a side), with the spindle running slowly see if all six led lights toggle on\off on the six boards...

Yes it does, also On the cmc web site they have some tech tips and one is what Im going through I think. It says to adjust my servo amplifier is that a good Idea. or is it the clogging noise?

the servoes won't affect your spindle...check the driver leds...

does the cogging go away as you speed up?...the parajust drive does run rough at very low rpms...still check the leds...

yes the clogging goes away as it speeds up. got any clues as to my motion error. when spindle is not on I can move all axis but as soon as I turn spindle on and try to move a axiz I get that alarm any hints to what might be going on??

power issue...you went with phase convertor, right?

do you have\know how to use a digital volt meter...

yes I have one, I am no pro but I now the basics pretty good. and yes I went the phase converer route an Anderson 5hp they said I would not need anything bigger
because it was not a hard start spindle.

measure the SINGLE phase ac voltage going to the spindle drive (be careful), also the servo drives, then recheck the single phase going to the servoes with the spindle running...could run this mill on single phase house power, but oh well...

Well how do I run in single, where is the spindle drive, servo drives, Are they in the right side cabinet, also if you go to cmcsystem.com click on tech tips and page down 4 times that is the alarm I get. How much voltage am I supposed to see.

you said motion error...am familiar with this...you need near 230 volts SINGLE PHASE ac on the two screws on the parajust drive (left cabinet)(i think marked ac input), (put your meter on ac volts, put a lead on both screw terminals)...what servoes do you have, i am guessing either cmc servomates or servo dynamics, either way check the single phase ac voltage feeding the drives,(right cabinet) i think they needed near 60 volts ac SINGLE PHASE...you will need to locate the 2 heavy wires feeding the drive system and check the same way as the spindle drive...i think some time back i mentioned no need for phase convertor for kmbx1 model hurco...the only thing you needed to do was disconnect the flood motor and replace with a single phase 115 volt unit (if it even had one, lots did not), and sort the single phase wiring out so that it was driving the spindle drive, the servoes, and the cnc power supply (easy for a decent electrician)...anyways, be careful and check the voltages to the servo drives, especially...i bet it is dropping when you run the spindle...

btw cmc servomates are randtronics...

Hurco FET Servo Amplifier I think thats what I have. If voltage is dropping how Do I fix
it.

One thing when I wired it I did not go thru the transformer was that wrong should I re wire it so that it does.

if the voltage is dropping, we will need to make sure your (house) single phase lines are feeding the spindle drive and the servo drive (transformer), NOT the third (generated) leg...again the servoes run fine until you run the spindle, right?...monitor the power to the servoes...we cannot have the third leg on the seroves or spindle drive inputs...

yes everything runs fine till I try and move with the spindle on, the transformer is the on on the machine on the back. what kind of voltage should I have coming out of my converter on each wire. how do I know which is the third leg.

i suppose ultimately what you could do is switch the (3) three phase wires (2) at a time and keep retrying the operation, might be the easiest thing to do...in other words lets say your three phase terminal 1 is red, then white, then black...try red black white, then black red white, trying to run between each trial...as for the voltages, your home power will measure near 240 volts ac BETWEEN the two (lead on both house lines), the house power will measure near 120 volts ac from each leg to ground line...the third leg will probably measure quite differently, usually much higher or lower, so i would check each to ground first, and try to identify the thrid leg...then try switching the lines as described...need to keep that third (basically unnecessary) leg from the single phase inputs to the spindle and servo drives...

I ended up calling a guy and he said I should hook up the transformer that could solve the problem if that did not work I need to tune my servos.

if the servoes were out they would NEVER run properly, not just (motion error) when the spindle is running...

so you think I should tune the servos. and not bother with the transformer

no...i said if the servoes were out they would NEVER run properly...which means whether the spindle is running or not has no bearing on the servo setups...you said the axes run fine UNTIL you turn the spindle on...so the servoes by themselves (setups, etc) are not likely the problem...

i stick with the idea that your generated leg (again, the third leg was never necessary for your machine to run) is one of the legs feeding the servo and\or servo drives...

Power problem I hooked voltmeter to the 3 legs and on two of them I had 230 and one was at 48v. got the samething on the acc contactor in right cabinet. now I checked the three legs to ground I think that was wrong it should be to 2 of the wires right
Tansformer maybe if I dont have the full volts and it is only allowing me to run one at a time is it a thought.

Which one is the third leg? also does it mater which wire goes to the main power switch. Because I have the 2 with the most volts on the outside and the other in the middle.

Sorry The three wires coming out of my converter to the main switch with the big fuses does it matter which wire goes where.

just try different combinations as described earlier and see what happens

one at 48 volts???yikes...48 volts from that leg to another leg, or that leg to ground?...ultimately if you are going to run 3 phase, all three legs need to be fairly close (specs call for 10%)...48 volts egads...

what did you measure on acc contactor??? i think we need 60 volts ac there...and if you check acc with the spindle running what do you get??? i bet it is even lower...do you have flood pump?

John where is the acc contactor, is it the one to the right of servoes
also where is my logic board and not sure if I have a flood pump but the switch in the back is on mist should I disconnect pump if I have one.

John, I got 230+ on leg to leg.

all three legs?...measure 1-2, 2-3, 1-3 then 1-ground, 2-ground, 3-ground and write them down...most convertors high a wild leg either high or low, all i have said all along is the generated leg needs to be separated from the parajust spindle drive, the acc contactor for the servoes, and the cnc supply...where did the 45 volts you mentioned earlier come from ("and one was at 48v")...john

the acc contactor will only have SINGLE phase (2 black wires connected through it)...i am not remembering where the contactor is, but it energizes (pulls in) when you press operate, so maybe that will help identify it, it seems it was next to the hurco drives...i am not working from prints, rather just from my memory, if i see one in my near future travels i will take photos...the reason i kept asking about the flood pump is because again, on your hurco it would be the only thing that required three phase power, no don't disconnect it, especially now that you bought the convertor...

That voltage was from ground.

well interesting I did check the volts to the acc contactor and it was 230+
also I tried to see what axis was giving me the problems and the x and y are good they moved smooth and together so I think it has to do with the spindle. One thing I noticied was that the z-axis is not smooth, so it is my spindle right. How do I fix the problem no that I know it is no anything else but the spindle when on.?

ok well the acc must feed the main transformer, and it steps the voltage down to the servo drives, which i think is around 60 volts ac...still does not make any sense you can jog the axes without any motion error until the spindle is turning...still seems power related...you might want to pull the brushes out of the motor and blow the carbon out (motor and tachometer armatures...4 motor brushes, 2 tachometer)...

How easy is it to do that? I just got off the phone with a guy from cmc and He said that I need to also check my step down transformer, like you said I do not need 230v at contactor. I also am missing a relay the one on the top right, I will do that first tonight. You are talking the z axis right as far as the brushes and tach? How do I test the stepdown tranformer.I also am not wired to the main transformer that is in the back of machine?

John Let me know how I can rewire for single phase if you can. Thanks You do know I owe you about 4 cases of beer!

i will work on a print and get back to you...the hurco kmb1 WILL run on single phase...let me copy\paste the first reply i ever made on cnczone, it was to you...

your hurco kmb1 will run on single phase power,period.

--------------------------------------------------------------------------------

drill...i have worked for hurco since september of 1984, i know the kmbx1 well...actually, the only requirement for three phase power on a kmb1 is for the three phase flood pump motor if it is so equipped...the spindle drive (parajust model a 5hp) requires single phase 230 volt power, the servo drives (most-likely cmc randtronics servomate) also require only single phase power, as does the cnc power supply...why get all involved in three phase generators or vfd's if you can simply replace the three phase flood motor with an inexpensive single phase flood pump...better yet, if you do not require flood, but can use mist coolant instead, disconnect the flood motor and you are good to go...if you take a close look at the parajust a drive, you will see labeled input power, and you will see only two power lines...the kmb1 will simply run on single phase, actually, it is the only hurco model that would, and it was a popular pole building\garage mill, you will need to connect your single phase power to the proper two wires on the three wire disconnect lugs,a good electrician can help, or get ahold of your local hurco rep, we would love to help,do not forget your ground wire connected to the ground lug...regards...john

The input power thats the one marked 230 output next to 230 3 phase out put,the lugs are they on the parajust or am I out to lunch.

do I just hook 230 single phase to that or do I need to still go thru the main switch.

never hook your power to anything but the main switch!...also, you must be going through the main transformer (T1), and the servo transformer, etc. but i will try to get some prints so i can speak from them, not memory...the acc contactor does supply 230 volts to the servo transformer (T2) where it is stepped down to 60 volts ac and sent to the servo drives where it is converted to 80 volts dc...the parajust requires 230 SINGLE phase, but i cannot remember if it went through the main transformer or not...the main transformer feeds the 115 volts for the cnc stepdown transformer (T3) as well, and the flood pump, if so equipped was the only contactor\motor that used three phase...so again you must be going through the main transformer in order to have the machine up and going if all you did was hook up to the main switch...you know, if you truly have good clean 230 three phase (1-2,2-3,1-3) and it is within 10% on the three legs, i suppose you might have a different problem, but it still seems power related...will hopefully get hands on some prints by tomorrow...later...john

ok that might be where my problem is the main trasformer I dont think I am right in that area, where is t1 t2 t3 are those at the transformer.

Hey John any luck on drawings. Also tried something today , when I turn spindle on and try to move axis I still get the same alarm. After I clear that alarm and just try and move an axis, withe spindle off. I looked at my amp boards and on all 3 I have the
BUS red led lights on. Is that something. I am going to run a ground from wall to machine just to check my ground and wire the transformer the right way. Who knows maybe it might work. Thanks

the bus alarms are result of power issue...you MUST wire through the main transformer (TI), it steps your incoming power down to the proper levels...prints still on way, sorry...

John, Well thanks to you I blew up my transformer!!!!
just kidding YOU were right I wired thru the transformer and it worked. It also made it run alot quiter and spindle runs alot smother!!!!!!! If you send me a private
email or message with your address I will send you money for a case of beer.
THANKS ALOT!!!!

will still try to forward prints, still trying to get them...do you have manuals with sample programs, etc?...if not i can email you a great one, but it is 10mb pdf format file...let me know...john

John that would be great. I do have a manual with sample prints. I sure would like a copy of that print though. Sorry had to change user name, got new computers at work.

here are a couple, still looking...

John, can you tell me explain to me the steps to pick up part zero. I want to pickup
the top left of a part, where most people pickup. Should I touch off with edge finder
x and y, write down the numbers. Go to data block 0 and do I enter in the number
that I got from edge finder. Is that the right way, or is there a different way? Thanks I got the pdf looks good.

yes, jog to where your edge finder does its thing,then in data block zero for say x hit table zero button and this stores the current position as part zero, do not forget to add\subtract the radius of the edge finder, or jog to edge where edge finder trips, hit table zero, raise z axis up and jog over the distance equal to the radius of the finder and hit table zero again, repeat for y axis, in tool setup you jog the particular tool down to just touching the part and hit tool cal button...do you have a operators manual, if not i can forward one with examples, but not through cnczone as it is 10mb in size...john

Hey John. I got it figured out last night. I kinda like how it does a helix.
Do you know how in/tan and out/tan work.
