    My default is PETG, as it's fairly easy to work with and has some of the best chemical resistance. Although I do have ABS as an option, but it's...

    Generally encoders fail completely, not intermittently. Have you checked all the wiring is OK? A broken wire (or one making intermittent...

    The machine has been running, so I'm guessing there must already be some form of isolation. Going by the photos, I'm guessing P17 is being used to...

    It's been a long time since I've used Mach3, so can't really help you there, but it'll depend on exactly how the speed control is being done. You'll...
