It is suport step/dir sir?? Because original stmbl are suported right, if posible open the step/dir interface mate, so we can used for mach3 or grbl, thank u somuch.

I'm running LinuxCNC/Axis 2.9.0-pre1..... on LMDE 6, using software stepping. I have a 3 axis CNC, with two motors on the X. Initial condition has the motherboard parallel port controlling the motors and a second parallel card doing some other details. One X motor works, the second does not.

I was trying to connect my g540 disable to the parallel port and one motor quit working, the 4th axis on the g540 (which is my second X motor, see image). Using an oscilloscope, I can see step/direction for the parallel port pins 2,3 (x) 4,5 (y) and 6,7 (z) when I use the arrow keys. Pins 8,9 have nothing when I use the arrow keys for x. I  figured I had blown up the parallel port, but somehow just those two pins.

Bought a PCI parallel card, changed stepconf to use that card instead of the MB parallel port. Same deal, I can move the X motor but the X2 motor doesn't do anything. I measured the new parallel port pins, same result. I can measure step/direction for pins 2-7, but pins 8 and 9 do nothing.

Somehow the signals on the 4th channel, pins 8-9, is not getting through. I think I have Stepconf set up right, it was a working machine before.

Help will be greatly appreciated!

Hey, i have a question about configuring a 6axis robot arm with lcnc, ive built myself a robot arm and im trying to control it via a puma560 simulation config, ive seen a youtube short of someone doing exactly that but he has no documentation on how he did it, im new to lcnc so i dont really know where to start with configuring physical pins, for context im using a rpi5 and want to use gpio pins for step/dir, ive got some tmc 5160t drivers to work and i get motion from them i just dont know how i would assign physical gpio pins to the already existing config Below ive linked the short where a robot arm is controlled by the puma560 config, if you stop at the right time you can see the tab name: youtube.com/shorts/js6OaVhUN2U?si=68d75rJqwbvCr9V0
