EVA3 - BLTouch `horizontal_move_z can't be less than probe's z_offset` #93

Closed DrMullings closed 2 years ago

DrMullings commented 2 years ago

When using the EVA3.0 or EVA 3.01 version of the BL Touch Holder I have Z offsets from 14 to 16 and therefore neither Z Tilt, nor the heightmap calibration works without adapting horizontal_move_z (default are 5 and 12) in the printer.cfg This adaption only seems to be a workaround, as it was not necessary in EVA 2.4

This looks like an issue to be open in RATOS, not here

This was introduced by switching from EVA 2.4 to 3.0 That is the reason why I opened the bug here and not in RatOS

91 should fix this or it's indeed something for RatOS to address.

@miklschmidt is this anything you can help with?

If you need a z offset of 14mm, or god forbid, 16mm (!!!!) for bltouch to work, you won't be able to print. Bltouch Z-offset should be between 2-4mm.

I'm closing this as not EVA related. If you need further help I suggest Discord :)

Just as a followup for everyone coming here in the future: This is indeed an RatOS caused issue, after homing the bed is moved to Z=12 and this is not taken in account when levelling from that position. As workaround one could just move to Z=0 after homing and start the levelling from there
