Start line disappeared?
Hi. I have the mk2 for about 1 month now. Very satisfied with it.
But since a couple of days the behaviour of printing just changed. Normally when I started a print, the nozzle went home, extruded a thick line of about 7 cm in the front left corner and then started the print.
I doesn't do that anymore. It directly starts with the print, which occasionally gives issues with the first layer ...
Why is the startline gone? is it a setting? I'm quite sure I didn't change any settings (but could be mistaken)
thnx
Re: Start line disappeared?
It's set in start gcode snippet of slicer. What slicer do you use?
Re: Start line disappeared?
Slic3r - Could you tell me what should be there?
Re: Start line disappeared?
Do you use Slic3r which come as part of 1.7.3 drivers installation? If yes, did you modify the settings?
Original start gcode:
M83 ; extruder relative mode
M104 S[first_layer_temperature] ; set extruder temp
M140 S[first_layer_bed_temperature] ; set bed temp
M190 S[first_layer_bed_temperature] ; wait for bed temp
M109 S[first_layer_temperature] ; wait for extruder temp
G28 W ; home all without mesh bed level
G80 ; mesh bed leveling
G1 Y-3.0 F1000.0 ; go outside pritn area
G1 X60.0 E9.0 F1000.0 ; intro line
G1 X100.0 E12.5 F1000.0 ; intro line

Yest I do use slic3r from the driver installation. Only thing I change once was add a rim for a model with a small base. Maybe I'll just remove it and reinstall this evening.

Hi Dieter,
it's possible that you change the active printer profile from "Original Prusa i3 MK2 with ZHop" or "Original Prusa i3 MK2 ColorPrint" to "-default" which does not include the gcode for this initial line.
Instead, the starting gcode just use:
G28 ; home all axes
G1 Z5 F5000 ; lift nozzle
Can you double-check that ?
I'm like Jon Snow, I know nothing.
Re: Start line disappeared?
Just got home from work ... and checked .... and I did actually put it on '-default-'. So everything solved.
Tknx very much people ... off to some more printing.
🙂
Re: Start line disappeared?
We need to get rid of the - default Slic3r settings in the source code. They can't be removed. I'll pass it to Vojtech.
