    Question DIY machine having issues...stepper motors the issue??

    Hi,

    I just started having this issue with my machine...wondering if the stepper motors could be the cause...i've tried three cuts of the same file i've always used...at some point in the routine they've all gone off (see attached image)
    they're cheap motors, I have an extra, so going to try swapping it out and hopefully its just that?

    Anyone else had issues like this??
    thx

    Stepper motors rarely go bad. It's likely something else is causing it.

    swapped the motor...i ran a different similar file...worked ok....then i ran the same file i usually do and was watching it...at some point it started doing weird stuff that not in the code...on one arc move it did a full circular motion...and in some of the straights i could see it doing a jerky movement...

    now i'm really worried....gecko driver botched somehow? no idea i have even trouble shoot this....

    The Gecko drive could not change an arc to a circle, that's more likely a controller or Gcode fault

    Re: DIY machine having issues...stepper motors the issue??

    thats why its the strangest thing...i just ran an alternate file, worked first time...tried my original file and back to this alternate file...and this strange stuff happening...so it can't be the gcode...

    so the gecko 540 could be at fault for this stuff????

    kinda lost here...

    Re: DIY machine having issues...stepper motors the issue??

    Random stuff like that can happen because of radio frequency interruption of the logic signals. Are you running the spindle leads next to the motor cables? Are they grounded at one end? One way to check if this is the problem is to run the program at a high Z level, or without the tool in place and the spindle off. Is someone doing arc welding nearby? Non-existent or bad grounding of the machine can also cause this.

    nothing changed on the machine itself or its setup...worked fine before...
    Will see if the dust theory works...?

    Do you have a fan on the G540?

    Hi AirB - Does it do it if you air cut? If you get the fault then rerun the code but in air to see if that makes a difference? Peter

    will try re exporting my gcode...but dont see it being that as it never happens the same way...pretty random...other than it seems to always be in the same axis the issue...

    cutting my re exported file again no problem...so weird...
    a cable issue? dunno...i moved my cables so they weren't dangling off the connectors like they have been for years but supported them...dunno...maybe I need to take apart my cable connectors and make sure all is good....?
