    I cleaned it all out.
    Kept my eyes on the call screw, walked away and it happened again.
    There is a fast movement in Y when it moves back to the next line to cut; I’m wondering if I can slow that movement down.

    Did you see my last comments where I cleaned everything up and it happened again. No Nose Dive, but it dropped a bit and messed up the PRZ
    So, I went back to the original PRZ, restarted from the line it goofed up on and it was running fine.
    I’m about 1/3rd through had to stop.
    I wrote down the line to go back and try from there tomorrow.

    Said Ger21 The noise your hearing is the motors stalling, or losing position. Once again its the machine, not the gcode. If the motors are stalling or missing steps your running program is going to screw up. Either the machine is not set up right or your binding and causing the motor issue as above. Once you understand that you will find your problem. If it was my machine I would loosen one at a time the coupling or remove the belt and see IF I could move that axis without binding. If they are all free and move without issues turn your attention to the setup for the controller and the computer running the Mach3.

    Have you lubricated everything yet? Now that you have explained things better your definitely losing steps now you need to figure out the cause. Start with lubrication now that you have cleaned things up since it needs to be done regardless. Then run the program again and report back.


    Also please post the feeds and speeds you're running for the part just to eliminate the possibility it has something to do with the toolpaths. If that's what was in the pdf I can't download it for some reason so let me know and I will look at it on my computer. Also I believe Gerry has said before that some of the Chinese machines have counterfeit Mach3 controller's maybe he can chime in and help you figure out if you have a legit Mach 3 control system. I'm just throwing some things out there since I don't use Mach3 and don't know if it could be causing the problem. Something definitely isn't right with the machine if it's running away on you, once again either Google the symptoms or maybe Gerry will help you out. I'm sure what's going on with your machine has happened to others and the information is available if you spend some time searching for it.

    WHY DO THEY STALL / LOOSE POSITION?

    I’ve owned this machine since 2014 or so. Used but in good shape.
    I replaced the Y coupling once.
    I lubed once with the wrong stuff.
    I’m not sure what to use on the ball screws.
    Can you recommend something from available from Lowe’s or Depot?
    Maybe that White grease in a spray can?
    Since the problem is in the Y and Z movement, I guess I’ll check those first?

    I also saw you NEVER lube the ball screws.
    Well? Do you?

    The fast movement is your rapid speed, you should be able to change it in Mach 3, that actually might be part of the problem. If it rapids too fast for the mechanical and motor limitations you will lose steps and that makes it lose location. Post a video of it running the part and messing up.

    If you have too fast of a rapid set and your machine can't handle it you will lose steps. This however still wouldn't explain a runaway machine, so you probably have a few things going on. Post some pictures of the machine and the electronics may be something will be obvious to someone reading the thread.

    See my post above #51. My ball screw and R&P system is cleaned and lubed on a regular basis.

    WHY DO THEY STALL / LOOSE POSITION?
    Could be a hundred different reasons.

    Binding.
    Lack of lubrication, or dust buildup in the bearings.
    Power Supply problem.
    Wiring problem.
    PC problem.
    Mach3 problem.

    I continue to search. I noticed a tiny crack in the coupling. It’s still very tight. But here is today’s cut.... I’m getting tired of this. Just asked Automation Technologies for parts

    Unless the crack you see is not a normal part of the coupling and its loose on the shaft then replacing parts may not solve your problem. Its interesting that you have been told over and over again what it could be and what to check but you seem to ignore all. I will check back from time to time to see how it comes out but no more comments from me.

    Problem with trying to video where it happens, is you don’t know when it’s gonna happen.
    It’s nearly an hour long program.

    So it’s not the software.
    I slowed down the feed to60
    I cut Corian at 100 so MDF at 60 with minor stepover shouldn’t do it.

    I’ll borrow my sons Go Pro at record an entire run. Hopefully I can edit it to see and HEAR the stagger.

    That tiny crack on the coupling does nothing.

    Just my two cents here, without reading the entire thread but if it's loosing steps which is what your last photo looks like to me, it may be the driver for the axis. The reason I say this is that because I have a G540 and for a similar reason my Z kept loosing steps and ultimately it turned out to be a faulty driver causing the issue.

    Is there a way you can swap the axis drivers, cables, steppers for comparison to each other?
