Lately, I have been experiencing some blobs after printing with my mixing hotend (e3d cyclops). It is known that for mixing hotends, it is beneficial to use firmware retraction, as you can retract from all inputs to take the pressure away.
So my setup looks like this (RRF 3.1.1, Duet 2 Maestro):
M563 P0 D0:1 H1 F0 S"MIDDLE_LEFT" ; define tool 0
M567 P0 E1:0 ; set mixing ratios for tool 0
Lately, I have introduced an additional restart length:
M207 P0 S2.1 F3000 T3000 R0.1 Z0 ; firmware retraction settings
M207 P1 S2.5 F3000 T3000 R0.3 Z0 ; firmware retraction settings
Now to the question:
When firmware retraction is done, does the additional unretract length apply to all drives involved in the tool?
If yes, this would be bad, as I am - at each G10+G11 - start to mix in another color. This could explain the behavior I am seeing.
If not, I need to look somewhere else...
