This is awesome! I actually just today started wiring up the retrofit of my EMCO Concept Mill 155. Newbie to linuxcnc, so it’s been going slow so far. Would you be open to sharing your setup files? I’ve got the same tool changer, would love to see your code for that.

I'm a bit concerned about the STEP/DIR wiring.

It appears that the thick white wires are grounding the STEP- and DIR- pins
This should never be done as it shorts out the STEP- and DIR- pins
possible damaging the driver chip.

If STEP- / DIR- are unused, they should be left unconnected.

Hello.

I Know that MPG mode is the default mode at startup for whb04b-6.  So When moving the handwheel  the FeedRate Override changes untill we press Cont or Step yellow button

Is there a way to start in Continuos o Step mode?????

I try tomorow a lower speed . Thank you very much for a quick replay

What exactly do you need help with?

Are you sure it is not stalling because your accel/velocity values are too high?

if the distance moved with a 100 mm command is not inversely proportional
to the scale, the hardware is not following the  command.

500 mm/s is way faster than is possible.

Even at 300 steps per mm, 500 mm/s  needs a 150 KHz step rate, but your base thread
period limits you to only about 5KHz (5 KHz = about 16.6 mm/sec at 300 steps/mm)
