MatterControl Auto Level going crazy

Postby maluco » 2017-Feb-Fri-23-Feb

I love the look and feel of Mattercontrol, but what I do not love is that when my Metal Plus begins the auto leveling phase it overshoots the 10x10 bed on the the second corner. Then it drops down and because the bed does not allow it to move much further than the bed, it extends just enough to drop the hotend towards the black metal versus the aluminum bed. WHY? That stops the printer in its tracks. Mattercontrol does not allow the bed shape to be anything other than rectangle or a circle. The metal plus is a square. But nevertheless I assumed entering the proper dims would tell the software that it is a square... How do I fix this? Thank you in advance!

Did you enter the proper dimensions in the firmware? No idea how you'd check that in Mattercontrol, but it's straightforward with Repetier-Host.

In general, you need to have three program settings all synchronized with the same bed dimensions:
1) Your slicer (Slic3r, Cura Engine, S3D...)
2) Your User Interface (Repetier, Cura/Pronterface, MatterControl...)
3) Your firmware in the printer (Marlin)

Some versions of Marlin give you control of bed dimensions in EEPROM settings; other versions don't. If your printer allows the nozzle to move outside the printable area, then it's not correctly configured in Marlin. However, since the probe is off to the side of the nozzle, it's permissible for the probe to go beyond the edge of the bed during printing.

Since I don't have a probe, I'm not entirely sure exactly which (combination?) of the three above-mentioned program setting control(s) where the probe looks for the bed - but I do know that the probing locations are configurable as offsets from the bed dimensions.
