Using a close loop stepper motor
-
Hi,
For several years, I have been using these MKS SERVO42B ( now there is a new version MKS SERVO42C) . I added them as external drives for the DUET 3D, on X and Y axes. They are connected to the LCD DRIVER 10 and Driver 11 of the duet 3d.
Recently I did a system upgrade to version 3.4 from version 2.05.
Unfortunately, I can not find a way to operate the X and Y axes anymore ( the Z-axis works fine).
I am adding here the config.g and the m122 output.non_working_config.g m122_not_working,txt.txt.I would appreciate any help,
Thanks -
Was it working in 2.05? Do you have that config still?
-
Here is the old config: config.g
if you look carefully there seems to be a mistake in the M584 command, at the start of the file ( but this is how it used to work).
In the remark section of the m584 command instead of starting with a ";" it starts with a "#" (UNIX likes comma - my mistake).Hope it clears something.
Thanks -

Hi
I got everything to work (in Version 3.4)Here is the config file if someone is interested :
