It's been a while. Lot's happened in the last almost 2 years. Death of our 35 year old son at the end of 2023 has kind of screwed up my world.

Going through the various postings from back in 2023 I never did see you post a copy of

measure_tool_inch.ngc

If you have the time would you post that please?

Thanks
John

Morning,

I replaced "encoder.00.position" with "stepgen.00.position-fb", which worked fine.

Then I checked the encoder and realized that it was counting in the negative direction when moving in positive coordinates. So, I added a minus sign in front of the stepper count in my .ini.
Now, the axis moves during the first part of the homing process. However, as soon as it hits the home switch for the first time which then tells it to change directions a "following Error" occurs.

Did this machine run the hob with a hydraulic motor for the hob spindle?

I have returned back to 2.9.4 but i will try again master.
In qtdragon_hd i can't find touch plate z axis probing.
This exists in qtdragon but can't find it to hd version.
Is somewhere hidden?

You should have mentioned this is a RPI.
-
When running the gcode file, set the Max Velocity slider to a lower value, till you do not get the joint following error anymore, then divide that value with 60 and set that value as the MAX_VELOCITY in the ini file.
-
Also noted the scaling, if you have direct drive belts with GT2 20 tooth belts, the scaling should be 40 or 80 depending on drive microstepping.

No spindle there at all.
Make a new config, choose a spinlde, choose some rough values for spindle PWM, save, start the config see if it shows the spindle.

one more question before i forget: what issue could be encountered by having a different model of servo driver? Given that you are driving both the spindle and c-axis both with step/dir signals, you just need a driver that can output step/dir, right?

Thank you very much! I successfully solved the problem.

Sorry, the error picture of yzEllipse_50.ngc is IMG_6981.JPG not IMG_7058.JPG.

My machine uses a CoreXY system for the XY axis and a linear system for the Z axis.
When I run yzEllipse_60.ngc, the machine stops and reports an error when returning to the home position.(IMG_7058.JPG)
The same issue occurs when running yzEllipse_50.ngc (IMG_7058.JPG).
