SnapMaker Artisan

How to reproduce

Start Orca, select SnapMaker Artisan (0.4 noozles), create a new project, import a .stl and slice to then print.

Actual results

Machine starts printing with some potential issues

Contamination of the print platform issue
Initial wiping material with a risk of scraping the edge issue
Long waiting time before printing issue

Expected results

These issues should not be present

Project file & Debug log uploads

SnapMaker has an updated start G-Code to decrease the likelyhood of these issues which should be updated in Orca.

Update: This updated code does not solve 100% of the scratching issue. Working with Snapmaker support on it. Will update if I have any news from them
