Hi there,
Got a nice Hemera and tried to get the retract settings for TPU right.
Made some test, but no matter what, it´s stringing and blobbing.
i created a retract test part, sliced it with prusaslicer and added after 10mm commands like M207 S or F
I didn´t noticed any difference, so i searched the problem and found it.
In prusaslicer, retract is set to 40mm/s and 0.5mm retract.
When i do a single "M207" before starting a print, i get the following:
M207
Retraction/un-retraction settings: length 2.00/2.00mm, speed 1000/1000mm/min, Z hop 0.00mm
Then i start the print and typing again M207, the console answers this:
M207
Retraction/un-retraction settings: length 2.00/2.00mm, speed 1000/1000mm/min, Z hop 0.00mm
Where gets the duet2 these settings for retract?!?
