After recent mishap caused by improper flexplate placement with fully lowered bed 😅 few small modifications: added chamfer on front bottom edge, so even if plate is slightly misaligned, it should push the bucket back instead of pushing it up until it breaks and/or back motor stalls (in my case - both happened 😅); top bridge between buckets was I use the start gcode from zombie3d, it purges a line on de left side: G21 ;metric values G90 ;absolute positioning M82 ;set extruder to absolute mode G28 ; Home all axes G92 E0 ; Reset Extruder G1 Z2. It can be tweaked to customised purge bucket geometries and brushes. This can cause filament to ooze out of the nozzle, leaving little blobs on the bed (or sometimes just getting the nozzle very dirty). Some filament are particularly oozy and may continue to ooze out of the nozzle for a second or two after retracting. 0 F(travel_speed) ;move the platform down 15mm G92 E0 I'd like to figure out some start gcode to do an initial purge/wipe line around the outside of the build plate (260mm print area) before moving on the main model to be printed. variable_purge_spd: 150 ; Speed, in mm/min, of the purge. 5 F600 ;finish purge line G1 Z0. ooveiulenfiaisgrbqehuhwlrymjaqgzuilgrwpglrkpvrrng
