    Syntec engineer has been very helpful and changed my ladder for the m8/m9 command to work. Thank you very much sir!

    About the error; Sounds like one of the two motors is out of sync with the other. The master is using the homing sensors to make the machine home properly. The slave should follow with the same amount of pulses fed back to the Syntec. There will always be a slight drift. Bad PID tuning of the servo's for example. Normally, the maximum allowable drift can be adjusted.

    Another possibility is that one side simple binds. Easy to test if you take off the motors or unplug the motors from the controller and move the carriage around (normally the brake is applied through a resistor that makes moving it near impossible) thinking about that, perhaps a different resistor on one of the two servos could cause an unbalance when braking. Perhaps you could contact your supplier for help?

    Did it had this issue from the beginning or did it just started?

    It doesnt happen all the time, just like the lost pulse and i believe happened from the beginning. I need to check connections again, and the carriage does move freely, so no binding.
    Ill continue to poke.
    Thanks!

    Serum glad I was able to help you out with that! If you need more stuff down the road let me know.

    Routerhead I have looked into the alarms you are having. I sent you the different things that can cause pulse loss that you can look into. As for the R44.4 alarm. I didnt have any documentation on it because that is actually an alarm that is entered into the ladder of your controller by your machine maker. With that being said I dont know how effectively I can assist you with it, but for me to even look into it I will need to obtain your ladder to see when that alarm is triggered. (Hopefully the ladder has enough comments for me to know what is going on in the machine.) If you would like to you can send me the machine back up of the controller I can read the ladder and alarm.

    I think serum has brought up a good idea of what the alarm is. Your machine manufacturer should definitely have the documentation or information on that alarm since they wrote it into the controller and it is caused by the hardware of the machine. If you can get in contact with them that would probably be the best solution. If you cannot I will try my best to decipher the ladder and come up with a solution.

    Lastly I know it was a different thread, but I have a step by step document for attaching the network to your controller I will send you.

    Yes! Very thankful for your help!!

    According to the manual, you can measure more tools and assign them to a certain tool-holder, for example T20 can be assigned to holder 1. (MG 1). so I would expect the machine to do an ATC if i give a T20 command using the location of T1.. It doesn't do anything though when i press start. Start blinks once, and no further action Would be nice to use this, I have this 80mm mill for flattening the spoilboard, but it's a bit of a struggle to measure, since the cutting edges are not at the same Z height as the center of this tool) (so i need to adjust the X/Y coordinates of the toolsetter for this tool once, measure it, and use delta Z for getting it at the right height for trueing the spoilboard. (that way all the tools are at a perfect Z-height).

    Would it be possible to have a T1 in the program, but to use a G42 T20?

    I know of offset of T20 is changing once I do a T20 in the tool-measuring menu. So would this value be used by the G43 command or is G43 ignored when T1 is active in the program?

    Serum Ideally yes thats how the T0000 can be programmed. Each bucket can be saved into a Rbit and when you enter Txx then the program should scan all the bucket register bits and find which Register bit value matches the user input value and tool change at that location.

    I know the way your software was developed by the machine maker only accounts for T1-T8. Any other T# is ignored. After looking into it I found that this is how a few machine makers advertise the ATC with 8 tools programmable.

    With that being said the controller itself can handle 90 tools where the user can decide which of the 8 spots has which tool number. I can provide the service for rewriting the programs to handle that for your machine and upgrade it. You can always shoot me an email for details on that upgrade.

As for the controller I can't answer it by just looking at it since we have none of those models in stock in the U.S. The AOC monitor is not usually used by our controller, but if you requested a screen larger than the ones we build that may have been custom and could still be our controller. Im sorry I'm not 100 percent familiar with the 10MF-8E model.

    What I can do is pass it on to some engineers in Taiwan and get there opinion. Also on the back of our controllers we have a serial number. If you can send me those numbers I can check the serial number to see if it is under our warranty and matches the product to make sure it is ours. Please PM me your email and phone number so that I can get a picture of the back of the controller from you and get this solved right away.
    I just wanted to Thank SyntecEngineer publicly for his help. He helped the best possible way considering our controllers were out of Warranty. We got them working - one was a loose connection and the other had a bad cable.
    Also, I heard from our Machinists that they like Syntec more and more as they use it - a lot more flexible.

    Question: Does Syntec offers any kind of paid training (in person/classroom/online) on its controllers? It can be anywhere in the world as long as it's in English.

    We are looking to buy 16-18 more machines within the next 3-4 months and will prefer at least half of them to have have tool changers. Considering the cost and learning curve of Syntec, I will feel a lot more comfortable to pull the trigger if we can have one or two engineers formally trained.

    Glad I could be of assistance Rakesh and I'm glad your machinists are enjoying our control system.

    As for the training yes Syntec can provide that. I can usually provide in house training around my area (California). Besides just the training it allows me to get to know the machinists so they can text/call me whenever they have issues. Are your engineers in the country or international? If international then perhaps I can briefly go over the controller pages/functions on a video conference or set them up with someone in their area. I'll contact you with more details via email.

    Glad you are considering Syntec for your machines! Can't go wrong if you ask me. (no bias here)

    Yep, i must say, after 2 months of use, i am an enthusiast too. (also enthusiastic about SyntecEngineer's support)

    6MA/6MB question

    In case of a worn tool, can you pause and replace/measure the tool and restart the program where it left?

    Hey Guys,
    I just checked this thread after many weeks... Very busy at work now.. machining wood...

    SERUM... I'm not sure I would recommend changing a tool in the middle of a program.. but I can think of something like this.

    If you stopped a program... changed the tool... and somehow got the machine to go through the tool measuring and recording procedure... in the "Monitor" screen.. where you can simulate, and see the code run at the same time...
    (This is the screen I like to have up when running programs) I know that You can select a line number for the controller to search out.. For example.. a line that starts with N450... and start the program from there...
    It seems to scan the hole code from the beginning.. but on my machine, it ignored the fact that I had tool #4 loaded.. and should be using tool #6...
    SO I need to make sure the spindle already has the correct tool #6 installed, before it continues the program from that line.
    BE CAREFUL when trying this.. as you also need to make sure your tool length offset is also correct.
    But the short answer is YES.. you can start to run a GCODE file from somewhere in the middle.

    Unhappy Re: Taiwan - SYNTEC - 6MB or 6MA - Controller Discussions

    I have a pretty troubling situation, that I hope you guys, or SYNTEC ENGINEER can advise me on.

    TO start, I had a homing sensor fail on my ballscrew+Servo motor driven Z-axis.
    It's a proximity switch.. and I already replaced it.. but there is still a problem I don't like.

    SO.. when the sensor failed, and I was homing the machine one morning.. the Z-axis moved UP (typical positive homing direction) but it went past the usual position, and continued untill the ballscrew maxed out against a physical METAL Stop... IT WAS SCARY.. and SYntec showed a Z-axis ALARM.. I think for overlaod,.. but definetly for servo-related error...

    I did fix the homing sensor.. but a new annoying problem now happens.

    HERE IS SOME IMPORTANT INFO I LEARNED... Syntec and Yaskawa work very well together. They truly work in closed loop... but homing is a bit different than other contollers...
    I have Sigma 7 motors and drivers... the Z-axis has a incremental encoder.. but apparently yaskawa uses what they call and "index" pulse... so once every full rotation or something like that.. there is a special pulse..
    kind of like a "zero" pulse... So it seems that SYNTEC watches for the homing sensor to trigger, but then looks for the "index" pulse to truly be homed.

    I know this for a fact, because when we were first setting up our machine, the Y-axis was almost coming off the linear rails when homing, ( I have planetary gearboxes on my Y-Axis)..
    So of course, I moved the homing sensor, about 5mm.. to change the homing position, by that much. It didn't HELP.. then I moved it 5mm more.. still didn't help.. another 5mm more, still no good.
    SO After I moved it about 25mm.. it finally worked....
    A yaskawa guy explained that it's because the Servo motor and drive use that index pulse...

    SO MY PROBLEM is that somehow, my Home in the Servo and Home in the Syntec Controller are not in sync.

    When the machine sees the home sensor.. it goes a little further than before..
    SO ALL MY Measurements are off..
    I DID find a parameter that allowed me to enter a value of how much I think the true Z-Axis Zero position should be adjusted.. But I'm not sure I like that as a pernament solution.

    How Can I change Back that Z-Axis index pulse to line up with the home sensor again, as before?... the homing sensor is in the exact same physical location.

    Please share your ideas

    THANK YOU

    Interesting. I'm sure my X and Y axis don't use this yaskawa encoder index (also using the sigma 7's, 850W motor, 1000w driver) ; it arrived with no motors attached to the y axis, in order to fit the shipping container; after receiving the machine, i moved the gantry by hand a couple of times, twisted the motors by hand before mounting them again and no error showed up. I took the X axis apart to align the cars on the lineair rails. Z axis behaviour unknown to me.

    Just be sure to remember to re-align the ATC, to save some of your ISO30 holders.

    Btw, I made a cheat-sheet for measuring the Z and Y position on the tool forks (inline ATC only) so you only need to measure 1Z position and 1Y position. Just use a dial indicator to measure the tools position in Z height and Y depth. Works like charm on mine. Only need to measure X position for each fork and all the other Y/Z values are calculated from 1 measurement, on fork 1.

    Hi Guys,Frank, I feel for you. My machine is set up more like serums in that once it finds the proximity switch, the axis reverses direction a certain number of pulses. I hope you didn't damage your servo or encoder, but I think that is where I would look. You may have sheared a key or swedged it enough so that there is slight play between commanded pulses and how many pulses the encoder is seeing, especially when reversing. This would show up only when reversing direction. So if there is play in the key, the encoder throw an error. Really, I am just guessing here, but I would start with checking backlash.
