Hi folks,
looked through the forum and could not find anything about it: It seems that the maximum Y position is 347mm (as opposed to my expectation it being 350mm). This caused a problem when I tried to print an object of 350mm size - the back part did not print correctly.
I investigated a bit, and tried this:
G90 ; set absolute positioning
G0 X10 Y347 ; Move (non-extruding) to X=10mm, Y=347mm
→ SM2 moves to Y=347 (according to the display)
G0 X10 Y350 ; now go to 350mm
→ No movement, stays at 347 mm
G0 X10 Y-10 ; now move to Y=-10mm
→ Moves to -10mm
So there are even 355mm of “addressable” print area in Y. When I now modify my slicer profile to have the origin offset, the GCode remains within the -10…347mm window, and all should be fine (print not yet started - will report later).
Also when I use the Jog screen, max Y is 347mm.
So for me lessons learned: Be careful with the slicer profile! Admittedly I basically never slice with Luban - has anyone here ever sliced something of 350mm size? Did it come out well with Luban?
Also: When using CNC and/or Laser, also watch Y-axis for large jobs.
What annoys me a bit is that Luban in the preview has a grid that goes out to 350mm, and there’s no warning that the Job exceeds available print area. Such a warning I’d find useful!
Any other insights that might help?
Btw.: used Prusa Slicer here. Looked quickly into Cura 5.0 - it seems on first glance that I even cannot change the origin… No idea if that becomes a problem when I try Cura next time. On the other hand: Having something of 350mm size is not something I do everyday
Cheers
Hauke
