Start GCode strange

[ravex1337]

Version

1.41.2+win64

Operating system type + version

Windows 10, 64Bit

Behavior

i put my start gcode from cura in and started printing. i was expecting slic3r to behave like so:

• go up
• extrude
• start printing (move from the current position to the first printing spot, so it moves diagonally down to the printbed)

but instead it does the following:

• go up
• extrude
• go down to 0.2mm
• slam my printbed holding clamp
• do weird stuff

Is this a new feature request? combine the first layer height with the first moving command, see my start code:

G28 -> my start code starts here G21 G90 M82 M107 G1 Z15.0 F9000 G92 E0 G1 F200 E15 G92 E0 G1 F9000 M420 S1 M900 K75 M117 Druckvorgang... -> and ends here ; Filament gcode M109 S197 ; set temperature and wait for it to be reached G21 ; set units to millimeters G90 ; use absolute coordinates M82 ; use absolute distances for extrusion G92 E0 G1 E-4.35000 F6000.00000 G92 E0 G1 Z0.200 F10800.000 -> here the printer moves down first G1 X77.828 Y67.320 Z0.200 -> and here goes the first printing instruction

i want it to combine these two lines so it moves diagonally down from where it extruded the priming amount, so it does not slam my print bed again.. may i change this in slic3r or do i have to edit my gcode every time like this: G1 X77.828 Y67.320 Z0.200 ?

my start G code: Drive all axes home lift z axes heat nossel extruded filament start printing

G28; home all axes G1 Z20 F200; lift nozzle M109 S [first_layer_temperature] G92 E0 G1 E35 F400

For the start gcode on my duet powered printer, I just use:

T0 ; make sure the hotend is selected M98 P/macros/PLA offset ; set z probe offset for pla M190 S[first_layer_bed_temperature] ; heat the bed and wait M104 S[first_layer_temperature] ; start heating the hotend G28 ; home all axes G32 ; bed calibration - RRF M109 S[first_layer_temperature] ; finish heating the hotend

I also have set in slic3r to one loop/20mm skirt, for the initial hotend prime.

Likely not a slicer issue. No discussion over the last 6 months, closing.
