Hey Sovol Forum I could use a little help maybe and thought I’d reach out. I’ve been trying to improve start and filament change gcode and being not that knowledgeable with gcode and programming I decided to try using AI to help me with it. There have been successes definitely but it’s also seeming like two steps forward one step back.
What I did was basically spend time watching the printing process, noting observations and came to the conclusion that nozzle wiping would be more effective If I swapped the purge bucket silicone wiper nozzle block from the left side to the right and the right side to the left. What that does is allows for the nozzle to be wiped on both sides of the silicone block.
It really does work better, the problem I’m facing now is with getting the nozzles to be parked centered on the blocks when at idle. The best I’ve achieved is T1 or the right extruder to park on the block some of the time it seems like but not both Not 100 percent of the time when they should be.
I’m being told that (Auto Park Mode) is fighting the start/filament change code and forcing the extruders often mostly to default park at their end stop location instead of the coordinates that I specified.
Here is that latest previous attempt to gain proper control of the tool parking location and timing. The M605 S1 wasn’t changed yet in the Start now I notice it like it was in the change code.
M605 S1 ; Auto-park mode
G28 ; Home all axes
G34 ; Z-alignment
G90 ; Absolute positioning
; Heat bed first
M140 S{first_layer_bed_temperature[0]}
M190 S{first_layer_bed_temperature[0]}
; Park T0 and start heating
T0
G1 X-33 F3000 ; Move to block
M104 S{first_layer_temperature[0]}
; Park T1 and start heating
T1
G1 Z20 F3000
G1 X340 F3000 ; Move to block
M104 S{first_layer_temperature[1]}
; Wait for both to heat
M109 T0 S{first_layer_temperature[0]}
M109 T1 S{first_layer_temperature[1]}
; Switch to starting tool
T{initial_tool}
G92 E0
Try M605 S0 (full control mode):
This disables ALL automatic parking. You manually control where both tools go.
Updated START G-CODE:
M605 S0 ; Full control mode (no auto-park)
G28 ; Home all axes
G34 ; Z-alignment
G90 ; Absolute positioning
; Heat bed
M140 S{first_layer_bed_temperature[0]}
M190 S{first_layer_bed_temperature[0]}
; Move T0 to block and heat
T0
G1 Z20 F3000
G1 X-33 F3000
M104 S{first_layer_temperature[0]}
; Move T1 to block and heat
T1
G1 Z20 F3000
G1 X340 F3000
M104 S{first_layer_temperature[1]}
; Wait for temps
M109 T0 S{first_layer_temperature[0]}
M109 T1 S{first_layer_temperature[1]}
T{initial_tool}
G92 E0
I wonder still even though I just caught the start code irregularity. AI mentioned that the Auto Park is a firmware thing. I asked if it can’t be solved in the Orca Machine Code if I could/would be able to modify that. The answer was yes though it was suggested to try the Orca Code first.
Could I or A.I. be missing element(s) that should be in (Before layer change G code, Layer change G code, or change extrusion role G code) or Is this definitely a matter that needs to have a firmware modification to allow?
These little optional fairly granular type improvements are those that I’m just now getting into after years of printing. It’s become necessary at this point for my sanity working with this thing…
I’d appreciate professional insight if you would.
Thanks
