Raspberry Pi 4 with Mesa 7c81

If 18" is long enough, Mesa's DB25M-IDC26 CABLE should be correct

hey! i was following along and this thread was really helpful. I have a similar setup with RPi and Mesa 7c81 but I have 5-axis breakout board (HW356). This is how it looks like

I have selected "One Partport" in PNCconf but the parallel port options are very different from Stepconf. Could you please post a screenshot of parallel port configuration in pncconf for my breakout board. Thanks!

You should select a parallel port like interface in pncconf, not a parallel port
(I would suggest the G540 option)

I have the following settings:

Base Information
Axis configuration: XYZ with Include Spindle
Mesa0 PCI/ Etho/ Partport with "One Partport"

Mesa 0
Board Name: 5i25-Internal Data
Firmware: G540x2
Num of encoder: 0
Nim of PWM: 0
Num of step generators: 3

And I have used I/O connector 3 which you said will be P1 on Mesa7c81.

Sorry I couldn't understand what you meant by "parallel port like". I would really appreciate your help.

The G540 _is_ a parallel port like configuration

(as opposed to a more complex configuration for a breakout like a 7I76 or 7I77)

I guess I am still too dumb to understand. I have used G540 in firmware and edited in the hm2_pci to hm2_rpspi and hm2_5i25.0 to hm2_7c81.0 in .hal and .ini file. What should I do with the partport? Should I use "One Partport" or "None" in pncconf?
