GO619 new build needs advise

[Scuba Steve]

Thanks Priddy, I just did not understand so I figure I better ask first. I have herd about this here MAJIC SMOKE and dont want none.
I went top Radio Shack today to get the p port cable and they didnt have one so Ill have to order it I guess.

I had a hard time with the wiring too but recall taking notes. I'll take a look at them tonight and help if I can. I remember crossing out what was on that diagram and writing what actually worked for my set up which is exactly what crevicereamer recommended

[cornbinder23]

The PP cable can be found here

The plug on the bottom of Kelings wiring diagram is just a DB9 plug with all the G540's inputs and outputs in one plug.
You do not have to wire it this way, I used a DB9 for the 4 inputs and a seperate one for the VFD hookups.

Here is another diagram for you to look over http://www.homanndesigns.com/pdfs/EN010_V8.pdf
Did you get your current set resistors? for the drive end of the motor plugs

BTW you will not need the VFD output hooked up because you are running the stock motor.

And the other wiring diagram I posted is more complete.

Here is the 48V relay
If you plan on running coolant you can use this to turn it on and off.

And here is a link to the IEC switch plug
for bringing 110V control power into the control box.

Thanks for doing my homework for me. Please bare with me as this is my first set up as I said before and its more than I thought.
I am a mill manager now but worked as a maint Super over the mill for 16 years but I worked with mostly 4160v, 480v starters and such. This little stuff is much more complex.
I have a 6 1/2 gallon parts washer that I was planning on using for a coolant pump for now just using the switch on it.
Are you saying that I do not need the VFD at all?
What about the 48 volt coil?
And last FOR NOW do you think I will be ok without limit switches for start up.
The Keling control box that I got had the e stop and the IEC plug for the back then the on off for the front. It has several screw hole configurations on the bottom but none that will fit the power supply unless I turn it on its side then its to tall. I can mount it with a strap of some kind just wish some of the holes would have fit.
Maybe I am asking for two much but just figured for the price it would have worked together better and then maybe some extra mounting screws but local hardware will do!!
Thanks you Guys

I did get some resistors. Like I said didnt know if I needed them or not but I got a selection of different ohm 1/4 watt. 10mega ohm and 100 ohm. Will one of these work or do I need to go back. I gotta hurry cause my Pancreas comes out in 15 days. Not looking forward to that for sure but good LORD willing I'll be back millin soon.

That sparked my memory. I think I did the same thing (probably at his recommendation). I wired the 3 motors to one db9 and possibly the limit switches, but I mutilated/cut a second slot and wired a separate db9 to run to the control board and relay to run the spindle. ended up being pretty simple... except for smelling/tasting/hearing magic smoke when I fried my x3 controller. I had 2 wires backwards to the controller AND some settings wrong in MACH3. I'm frustration I physically cut the wires to the power switch and safely taped them. later a friend came over to help and I had un-taped them to test power and didn't tape when I plugged her in. POW! dumb.

can't remember if I already posted this pminmo link. its got I'm controlling spindle via mach 3.

[PriddyShiddy]

I had to drill and tap holes to mount my unregulated PSU too. its set for one specific supply.. I wondered what the other holes were for then just drilled and forgot.

you DO need the vfd, lines if you want mach to control your speed. some people just control the speed manually. I cant imagine doing that as I program roughing and finishing cuts at different depths/feeds/RPMs.

the spindle control wasn't TOO hard. iirc it just needed a 5v wall wart which I wired to the control box power switch, a 120v 20 amp relay with 5v switching (can't remember exact specs on the one I found locally), some wire and some patience. I used the easier configuration in that link. so when I turn on the cnc I *then reach over and* turn on the x3 power switch, and set direction to forward. from there M3 fires up the spindle and S(number) sets the desired speed.

[cornbinder23]

He WOULD need the VFD line if he was trying to control an X3 spindle
The build thread says G0619 which is the SX3.
So unless he buys a VFD he will not need that output at this time.
And I would recommend running the limits and vfd seperately(ie:in the same connector) just to minimize any source of noise on the lines for the limits/homes

You can set-up your switches as home switches and then setup soft limits, or you can use the home switches as limit switches as well, mach will know when it has reached a switch regardless of which one is tripped.
You setup the direction that you want to home in and when you home the machine mach will treat the limit switch as a home switch, by making the switch and then backing off the switch a little setting the home position.
When you are not homing mach will treat them as limit switches.
It homes one axis at a time, I dont know if you can set it to home all three axis at a time. But the extra time allows me to walk around and hit the one shot oiler is trivial when homing each axis seperately.

Steve, man I hope everything goes well on your surgery, I wish you well and just think it will give you all the time in the world to play with software.

I iz gonna learn me to pay attention some day. I swear. had X3 on the brain.

[Scuba Steve]

Here are a few pictures of what I have. Just got my CNC Fusion kit today. Got just a few more parts to go. Waiting on CNC Fusion gas shock now.
What do yall think about the 1/4 watt 100 ohm resistors? Will they work or do I need somthing else for motor leads? The power supply came with some jumpers installed. If you can see in the picture. Do I leave these? Control box pics are of power supply with screw patern lined up but the box isnt tall enough to put on its side so Ill drill my own. No problem just figured it would come ready. If I would have spent the buck-a-roos to buy the completed box I wouldnt have anything to complain about. The other pic is the smoth stepper and cables Keling said I would need to run with windows 7 32bit. Will this benifit me anytime in the future?
Priddy or Cornbinder what about the 48 volt coil. Why is it needed and where can I get it and the limits/home switches from?
Thanks for your time guys its worth alot to me. I am sure the other Steven on here appreciates it too!!

I went with Honeywell switches for the x and y (link on my build thread... i'm on my PC not my phone where all my links are saved so I would have to google it also) They are basically "everything" proof, but if your not going to run flood coolant it may be overkill. Really ANY NC (normally closed) switch will work with a little creativity. CreviceReamer shows exactly how he did his. I think I had some decent pics of mine. Radio Shack has cheap ones FYI. I figured that wasn't a place I wanted to save money.

I feel a little slow saying this, but I have no idea what a 48volt coil is for unless it means the power supply which you already have. I had the same one, but it was dead out of the box. I got the unregulated one for the price difference because Ken at Keling said it was "better" but people "don't want to spend the extra $10" so he doesn't push it. Mine has a HUGE coil so I'm guessing that is where the coil is coming in??? I am a FAR cry from comfortable with electronics and honestly the fact that I got mine wired and has been working for this long without catching on fire and blowing up is amazing.

I don't remember anything about a coil, but my head is overflowing with the scraps of CAM that I am retaining in my quest for learning. Your far enough in that this shouldn't be able to scare you off; so here it is: the build is the easy part all the info is there for the searching and asking. CAD and CAM are the more challenging of things I have ever attempted. Also not being an operator before... every mistake costs me $40 it seems like. Its fun and rewarding though and even little things are triumphs.

Your rolling along man; keep it going. Hopefully you can get this all buttoned up before your surgery and have a bunch of code written to test when you can lift stuff off and on the mill. Best of luck.

let me know if you still want me to look through my notes. they are mostly just how I wired it which is just a variation of the keling example.
