Update:
looks like the problem is located in the ‘Custom G-code’ section in the ‘Printer Settings’ in Slic3r (K8200_pla_standard_new).
In the ‘Start G-code’ part, the parameter M109 is ‘hard coded’ and thus set to 190°C.
So I started a new ‘Printer Settings’-profile.
When I remove the M109 code from the ‘Start G-code’ and run Slic3r again with the new profile, a new M109-code is generated after the ‘Start G-code’ with the value that is set for ‘First Layer Extruder Temperature’ in the ‘Filament Settings’-profile. Unfortunatly the code is placed after the ‘prime the nozzle’-instruction (which is also part of the ‘Start G-code’-section.
When I remove this code from ‘Start G-code’-section and run Slic3r, there is no ‘prime the nozzle’ instruction generated.
How do I solve this? Sure would like to prime the nozzle before starting to print.
