davew_tx,
Well, I didn't see anything OBVIOUS.
Here's the end of Creator's header:
.......
; retractionOozeRate,100
; onlyWipeOutlines,1
Here are the first few things it sends:
G90 ; use absolute coordinates
M82 ; absolute extrusion distances
G21 ; set units to millimeters
M106 S0
M104 S226 T0
M109 S226 T0
M104 S226 T0 sets the extruder temperature setpoint to 226 C. M109 makes the printer wait for temperature to stabilize before continuing. Makes sense, because the header has:
; temperatureSetpointTemperatures,226
; temperatureStabilizeAtStartup,1
Next is your 'start g-code':
G28 ; home all axes
G1 Y50 F9600 ; move forward to avoid binder clips
G1 X205 ; move off platform
G92 E0 ; zero extruder
G1 E15 F225 ; purge nozzle
G92 E0 ; zero extruder
G1 X190 F1200 ; slow wipe
Note that there's a blank line in the G-code at this point. The system should tolerate it, but you may want to edit your start G-code and remove extra blank lines at the end of it, just in case that's the stopping point.
Now we reset the extruder "zero point", retract 0.5 mm of filament:
G92 E0
G1 E-0.5 F1200
Then set up the tool to Tool 0 (Extruder):
; layer 1, Z = 0.2375
T0
; tool H0.25 W0.503
and do a rapid to the starting position:
G0 X77.132 Y113.776 F15000
Now position Z for the first layer, return the filament to position zero (undo the retract), then re-zero the extruder position:
G0 Z0.237 F1200
G1 E0 F360
G92 E0
and do the first couple lines of filament:
G1 X78.359 Y113.202 E0.0637 F3300
G1 X79.667 Y112.849 E0.1274
Now, I've seen the retract done differently in the past. Previously, I've seen the extruder position set to 0.5 with G92, then extrude to position zero (retract) with G1 E0, do the rapid, then extrude back to position 0.5 with G1, then reset the extruder with G92 E0 ---- rather than extruding to "-0.5".
How far along does it get before stopping? Are any lines of filament extruded onto the bed?
