Prusa i3 MK2 GCode Temp order, nozzle prime

Thu Jan 10, 2019 8:56 pm

I have a Prusa i3 MK2. I recently bought S3D to try instead of Slic3r PE, mainly because the supports in Slic3r suck. Anyhow, I'm having a couple of issues.

1. The gcode is outputted with:
M140 S50 (set bed temp)
M190 S50 (wait for bed temp)
before the nozzle temp, so it wants to wait for the bed to get to temp before it heats the nozzle. I need them to be concurrent so it sets the bed and nozzle temp then waits for the bed and nozzle to get up to temp.

2. Slic3r puts this code right after bed leveling to prime the nozzle before it starts printing. On big prints it isn't a huge issue because the perimeter is large enough to get it flowing correctly but on small prints it doesn't have enough time. Do I just add it to the start script?
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

Thanks!

Just make sure you put that in after the extruder's temperature has been stabilized.

Unfortunately i try that but the simplify3d add after the start script G1 E-2 (if you add a retraction).
That behavior doesn't help and I lose some lines at the beginning of the print.
How can I get-rid of that?
