  • I wonder what mode those Linistepper are running in? The motors sound a bit rough, so I'm guessing they are in full or half step... Have you tried them with one of the microstepping modes?

  • @JamesMichaelNewton Your correct that the selected mode is half-step.

    Since I changed the current resistors, I would need to change them also for the microstepping modes and I really didn't think there was any justification for this since the resolution is good enough for me and I don't seem to suffer from resonance.

  • This is just what I need :D What interface is used between PC parallel port and LiniStepper drivers??? Some link to shematic, pls? And what for 4th linistepper is being used ??? 1-x, 2nd-y and 3rd for pencil up/down, 4th ? ( I probably don't need it for PCB drilling ) what PSU is used ? Thanks :)

  • Interface is a CNC4PC board and a small circuit used to enable low power mode.

    4th axis is rotary table on mill.

  • Indeed they are.

  • They are 4 linistepper controllers by Roman Black, I see... :)

  • Excellent!

    Congratulations
