SuperRacer with Klipper and Sherpa Directdrive

Hey,

thank you so much for your guide. I followed and upgraded my printer with the Sherpa. I have some questions about it.

Is it right that the Klipper ignore my start gcode from prusa slicer (purge line)?

What do you change after swap to the Sherpa extruder in your slicer? Retraction? Something else?

Kind regards
Benni

You need to share your start G-Code so we can have a look.

After upgrading to the Sherpa, I updated retraction. But you need to fine tune your profile again, if you want the best results.

My startcode:

;STARTGCODE
M117 Initializing
M83 ; extruder relative mode
M107
G28 ;Home
M900 K0.05
M140 S[first_layer_bed_temperature] ; set bed temp
M190 S[first_layer_bed_temperature] ; wait for bed temp
M104 S[first_layer_temperature] ; set extruder temp
M109 S[first_layer_temperature] ; wait for extruder temp

G92 E0
G1 X-98 Y0 Z0.2 F4000 ; move to arc start
G3 X0 Y-98 I98 Z0.2 E40 F400 ; lay arc stripe 90deg
G0 Z1
G92 E0.0

Yeah my first testprint doesnt looks good :confused: there must be a lot of fine tuning.
