SM2 A350, with QS and Bracing. Luban 4.15

I seem to have run into an issue with Luban’s CNC module and could use some input while awaiting SM response.

I made a model in Sketchup and exported a STL file. I put it in the CNC module and 2 issues:

It needs REPAIRING. I tried the REPAIR function and nothing seems to happen. I import it into the 3DP module, it says it needs repairing so I repair it. I then export that STL and import it into the CNC module and it again says it needs repairing. I went ahead with it and it looked good in the simulation, so I ran it, and it looks ‘okay’; there is a few weird tool paths that take a nick out of part of it, but it did run pretty much as wanted. I looked at the gcode and might be able to edit out the 6-8 took paths that are obviously wrong; they are obvious in NCViewer.

Any thoughts on the Luban REPAIR function in the CNC module. (Yes, I know it isn’t the best CNC software, but up until this, it gave me what I need)

The other issue is the orientation. In the STL 3D View, the model is oriented vertically, not on the build plate.

I go back and regenerate another STL with the orientation vertical, import it and it sits on the bed just fine. I run the model as above and it works correct. Viewing it in NCViewer, the orientation is not correct there. Exploring further, I make a larger model and try again. The model is 285 mm long. When I look at it in NCViewer before committing to 30-hours on the CNC, it looks like it is cut off. The CNC dimensions are supposed to be W320 x D335 x H260 mm, so the 285mm model should have fit. Nope, the model is actually vertical and hit the 260mm maximum on height, even though it ran just fine with the previous model doing the same orientation issue and on the bed correctly.

Anybody else noticed this issue? Is there someway to reorient the CNC build plate that I’m missing?

I went back to Luban 4.14 and it was the same. I haven’t gone back further yet.

All thoughts appreciated; snide comments about limitations of Luban, not so much. I already know that.

I would try to play around in mesh mixer. It should be able to repair the model and there is surely a way to reorient the model origin, i guess..

Or do the reorientation in sketchup?

Quick search, apologies if its not correct:

Thanks. I CAN reorient and it works up to the point of vertical height limits, which is way less than the XY limits. But, why is it orienting wrong but actually working on the SM? I looked but can’t find any “orientation” settings, so, a bad bug in Luban?
