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 direction
When step 5 is performed Y axis supposed to move 1mm but the U axis moves back to the home position unintentionally instead.
@dc42 I just have upgraded to 2.04RC1 and the problem still occurs
@dc42 Do you have any idea about that?
@mrsdelish It also happens on a device which employs manual bed leveling. (without probe)
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.

@veti yes from x30 to x270 it moves.
@veti In order to prevent confusion because of U and V axis, i edited first post and submitted simpler config file. This belongs to another device which runs on same hardware and firmware and problem still exists. What i mean is it is not relevant to creating additional axes.
X and Y axes are independent for sure. They are driven by seperate stepper with no mapping applied to each other.
@veti If you tell me what exactly do you want to see i can help you better. Because product is commercial and under development.
@droftarts neither both of them have M556. There is no axis compensation.
@Veti Error is not consistent so i could not experiment that.
@veti said in Unintentional axis movement:
M584 must come earlier in config.g than any M350 and M906 commands. If it creates new axes, it must also be earlier than any M92, M201, M203, M208, M350, M566, M574 , M667 and M669 commands.
I fixed the things you mentioned, problem is still there. Thank you for correction though.
Hello,
In some cases Y axis is moving certain amount unintentionally. I use three-point manual bed leveling and nozzle travels 3 points respectively.
Here the coordinates of those points are:
[“X30 Y30”, “X270 Y30", “X170 Y300”]
First move: G1 X30 Y30 (No problem)
Second move: G1 X270 Y30 (X goes to 270 and Y supposed to stay still but it moves anyway. It moves approximately 3-4 milimeters in positive direction.)
All movements are done in absolute cartesian coordinate system.
Hardware: Duet2 Wifi
Firmware: 2.03beta3
What would cause this?
Thanks in advance.
