Describe your issue:

Am trying to get this printer to work reliably but am having a problem with movement. I am trying to do a “calibate_probe” so I’m trying to move my X and Y to the center of the bed. I’ve tried “G1 x50” or G1 y50" or have used the buttons in Mainsail, I always the the error “Move out of range: 5.000 0.000 207.029 [0.000]” or something similar. What seems strange is that it is trying to move Z further than the endstop ( Z is max at 207 ). I have no Idea what is causing this. I’m about to give up on Klipper and go back to Marlin.

Hello @lcjnsb !

You have position_max = 207 for the Z-axes.

So when yo try to move beyond that, you get an error.

Move out of range: 5.000 0.000 207.029 [0.000]

Yes I agree, but I get the error after I home ( G28 ) and then try to move the X or Y axis. Is this Klipper trying to lower the Z before the move?

Now I see: You have a BLTouch.

You have to change your config for stepper_z:

Yes I do have a BLTouch, but I don’t use to home. I ran all the tests with “BLTOUCH_DEBUG COMMAND…” and it tests ok. The printer homes z at Z MAX (207) . When Z is at 0.00 the BLTouch is about 2 mm above the bed. Here is another piece to the puzzle, if i raise the bed ( ie M91 , G1 Z-1 F1500 ) via the icon on Mainsail I am able to move the X and Y. But the issue still remains, Z wants to move beyond home on an X or Y move.

This sounds weird. Maybe:

  1. You home
  2. After homing the printer is at Z=207
  3. You move X or Y
  4. Your bed_mesh kicks in and pushes your Z beyond 207
  5. Klipper errors out

Does it also happen when:

  1. G28
  2. BED_MESH_CLEAR
  3. Move X or Y?
7

No it doesn’t.
If I do the commands you suggest it works as expected, but the if the bed_mesh is active the opposite happens
G28 homes and sets Z at 207.00
G1 X100 Y100 moves as expected but sets Z at 207.00

If I issue BED_MESH_PROFILE LOAD=default and then issue the same commands the Z is set to 207.60.

I hope this is understandable. Should this be reported as an issue on Github or do you think this is something I have configured incorrectly?

This is expected behavior.
If you have a mesh loaded then your Z-value gets corrected on each G1 move according to the relevant mesh position.
If this mesh correction pushes your Z-value out of the max bounds then Klipper will error out.

Coincidentally an upcoming change will “solve” this issue for you. See Klipper changes to [bed_mesh] module · Issue #5983 · Klipper3d/klipper · GitHub

Thank you, I will wait for the update.
