Unintentional axis movement
-
does the y stepper motor actually move when doing the move from 30 to 270?
-
@veti yes from x30 to x270 it moves.
-
and you ruled out any mechanical issue? like moving the head manually when the duet is off to see if the movement happens as well?
without axis compensation there should be no movement on the y motor.
can you also post the config-overwrite -
I ruled out all mechanical issues, all of our devices have this problem.
config-overwrite.g contains only PID and BL Touch parameters.
Oddly enough, this is not happening while printing. Because dimensions are true.

This movement only happens when you probe your bed? If that is the case there is probably a probe offset(G31) in Y set somewhere, since the i.e:
G30 X100 Y100 uses position of probe(nominal tool holder position & probe offset) , where as
G1 X100 Y100 uses active tool position(nominal tool holder position & tool offset).
Check your config.g, homeX/Z/Y.g and Bed.g for any G31 with a XY value or G10 tool offset in XY. -
i dont see anything in the config that would explain that.
just to rule out any firmware problem please update to the stable 2.03 -
@mrsdelish It also happens on a device which employs manual bed leveling. (without probe)
-
@dc42 Do you have any idea about that?

@kerembyl said in Unintentional axis movement:
Firmware: 2.03beta3
Beta versions of firmware are not supported once a later beta or (as in this case) the corresponding full release has been published. So you should upgrade to 2.03 (final release) or 2.04RC1 and test again.

@dc42 I just have upgraded to 2.04RC1 and the problem still occurs
-
I experience something similar to that on my IDEX configuration. Steps to reproduce this problem: (all steps done via web interface)
Step 1: Home All
Step 2: Select Tool 1 (U axis)
Step 3: Move Y axis 100 mm in positive direction
Step 4: Move U axis 15 (or any value) in negative direction
Step 5: Move Y axis 1 mm in positive directionWhen step 5 is performed Y axis supposed to move 1mm but the U axis moves back to the home position unintentionally instead.
