Flsun SR

How to reproduce

• Download and install the Orca slicer
• Setup Flsun SR 3D printer
• Bring any STL or 3MF files onto the print bed.
• Slice it with the default slicer PLA material settings.

Actual results

The First Layer Purge lines are always outside the print bed area.

Expected results

If we are using this G code, the Axis of the FLsun 3D printer is colliding with the structure of the 3D printer.

I have the same problem here on my Sovol SV06+. Downgraded to a dev build installer i had lying around from May 19th and it works again. It also affects adaptive meshing, it tries to mesh the entire bed then when it goes to purge it errors out because it tries to purge outside of the bed. In the klipper log it doesn't appear to ever call for the mesh points, it just starts meshing the entire bed. I haven't changed anything in my printer.cfg, this appears to have snuck into Orca at some point in the last couple weeks. Tried an alpha version I had from the 29th and it also had this bug.

This might be related to KAMP adaptive purging, as turning it off seemingly removes this issue. But it worked before.

I think I found a solution/workaround, had to enable "object exclusion" in Orca, it hasn't been necessary before and I just had it in my printer.cfg, so idk what's up with that.

I had this problem too and couldn't find a solution online, so I decided to fix it myself and it worked. I just looked at the starting G-code, found the lines where the purge line starts and ends, and moved them inward. It wasn't hard to fix, and below I provide the adjusted code.

The essential modification is in these lines of code:

Before ... G1 F3000 Z1 G1 X-150 Y0 Z0.4 ... G3 X0 Y-130 I150 Z0.3 E30 F2000 ...

After ... G1 Z150 G1 X-130 Y0 Z0.4 F3000 ... G3 X0 Y-130 I130 Z0.3 E40 F2700 ...
