It gives out several information about the previous loaded configuration for the mx4660. Especially the pin allocation. The Output is in MesaConf.txt in my previous post.

Just one point, unrelated to your current problems, you probably want to select "no parallel ports"

Do your stepper drives need to be enabled? Are the motors locked or free?

Also for testing you should disable the charge pump (since its not setup by pncconf)
and use generous vales for step time (say 5000 ns)

Thanks for your reply. I got the steppers moving!

First issue was the Parport. I thought, that the Mesacard is a Parport. So I checked the "none".
Second point was the Jumper for "Chargepump" and "Smoother" on the MX4660. Now they are both on.
Third problem was the scale calculation window. It writes strange values after configuration. Maybe its about comma and point notation in numbers?

I attached the config folder.

Next steps: complete and refine the initial configuration in pnc conf. I will keep you up to date!

Thanks
Mathias

The archive contains at least three configs. I assume you are asking about the my_LinuxCNC_machine one?

Step-scales of 2000 steps per mm(?) seem believable for high microstep ratios or gearing. What numbers would you expect?

You limits seem large, unless the machine really is approximately as big as a planet. (and I think we would have noticed it)

your are right, its my_LinuxCNC_machine.

the limits are that generous, to have enough space on my table to jog over... The true machine is 3000x1500x190mm.
The stepscale should represent the hardware selected microstepping of 10. It is a Rack and pinion drive with gear. At the end, one revolution will move the axis ca. 38 mm. So the Scale means steps per mm?
Do you know how to set the timings? The values I have added were just copied from ...
I want the machine to run in rapid mode 12m/min.

For me its very interesting to configure the xyyz. I want to have a "homing corner" with a touch probe and softlimits. So I plan to use 4 proximity switches. If you have any further hints for me, It would be great.

Thanks
Mathias
