Best way to get code changes for specific hardware into master would be to create a pull request with the description of the issue and the proposed (and tested) changes.

No double posting please.

That's the current status. A few startup errors have gone away, but I think I need to change the entire pin assignment now. Are there any other serious errors you see besides the pin assignments?

   

exactly right. all my logic changed to base-thread.. and the spindle rotation works as expected. spindle speed mode or c-axis mode.

thank you PCW
best regards

I would think Logic should be possible with stepgen signals if
you addf the logic components to the base thread instead of the servo thread.

I tried using two modes on the lathe spindle.

I want to be able to change the spindle speed mode to c-axis mode which can be changed by entering Mcode

Here is an example of my code:

#######################

net caxis-cc-step <= stepgen.2.up
net caxis-ccw-step <= stepgen.2.down

net mode-caxis => and2.10.in0 => and2.11.in0
net caxis-cc-step => and2.10.in1
net caxis-ccw-step => and2.11.in1
net caxis-cc-out and2.10.out => or2.6.in0
net caxis-ccw-out and2.11.out => or2.7.in0



net spindle-cw-step <= stepgen.4.up
net spindle-ccw-step <= stepgen.4.down

net mode-spindle => and2.12.in0 => and2.13.in0
net spindle-cw-step => and2.12.in1
net spindle-ccw-step => and2.13.in1
net sp-cc-out and2.12.out => or2.6.in1
net sp-ccw-out and2.13.out => or2.7.in1

net servo-cc or2.6.out => parport.0.pin-08-out
net servo-ccw or2.7.out => parport.0.pin-09-out

#######################

M198 code:
#!/bin/bash
halcmd sets mode-caxis True
halcmd sets mode-spindle False
exit 0


M199 code:
#!/bin/bash
halcmd sets mode-caxis False
halcmd sets mode-spindle True
exit 0

#######################

I have tried all the codes above. M-code works well, it can change the spindle mode to c-axis or c-axis to spindle mode. but the resulting signal is not perfect.

I assume that the stepgen signal cannot use and2 or or2 logic, so that the stepping signal is damaged?

Uhi, das ist ja süß... all in one.

Ja viel können muss das nicht... Es handelt sich um eine Drehmaschine...

Ich habe aktuell dieses Interface:

Mir geht es für das erste erst mal darum, mich mit diesem LinuxCNC zu befassen...

Ich hoffe es gibt hier sehr Hilfsbereite und schlaue Menschen in diesem Forum... ich selber kontruiere und baue Maschinen inkl. Elektrik aber bei Software ist es bei mir dann vorbei.

Tried this out but got following errors with large acceleration violations

Running the LinuxCNC logo:

 

How many degrees of backlash at the spindle?
 With this and the thread pitch, you could determine
the Z axis error caused by the backlash to see how serious it is.

I guess you could even make a hal backlash component for the
encoder position if need be. (create a deadzone on reversals)

Thank you for the feedback
