mesaCT, 7i95t and SPINx

Hello,I'm new to LinuxCNC and come from an electronics background, with good familiarity in C. I installed the MesaCT tool and managed to get the three steppers for XYZ working. However, in the spindle tab of the tool, I can't select anything; all buttons are greyed out. I would like to connect the SPINx to channel 5, where I assume the PWM signal is. What settings do I need to adjust in MesaCT to implement this? Writing the .hal file still confuses me a bit. Does anyone have a sample configuration, or can anyone advise what settings I need to adjust in MesaCT to get the spindle running?
Best regards, Jörg

On channel 5, the Dir signal switches with the change of direction, but I don't have a PWM output on Step. I have attached the configuration.Best regards, Jörg

SCALE = 24000

Your configuration files helped me. I suffered with this problem for 2 weeks.

Hello,All my issues are resolved. The spindle is running, and the end stops and stepper motors are also functioning. For those looking for an example, I have attached the files.

Hi,

I'm configuring a kind of lathe with one 5i25 and two 7i77 and I'm facing the same problem : in the spindle tab of Mesa CT, I can't select anything; all buttons are greyed out.
Where does it come from ?

Jôrg, did you terminate the configuration by hand or with Mesa CT? You did'nt explained what's wrong with your spindle tab.

I've another problem with analog outputs but I just saw Peter's answer (forum.linuxcnc.org/24-hal-components/528...how-and-is-not-found) so it should be ok. In case it would be related... I would try it tomorrow.

Thanks for posting the files, I'll incorporate that into Mesa CT as soon as possible.
