Hello,
First of all please excuse the title of this post, literally don't know what to call it.
I have been experimenting with timelapses and i've added extra g-code on the layer change to move the head out of the way before it changes layer height and octoprint snaps the image.
G1 E-1.000 F1200; Stop extruder
G1 F9000 X114 Y62; Move to snapshot position
When I view the print output in simplify3D, it shows the filament being extruded out to the position I specified, changing layer and then extruding back to the next position in the gcode.
I tried adding the stop extruder line to the code but once this is complete the layer changes, it restarts the extruder and prints a line to the next position/
I examined the gcode for this file and it shows that this only occurs at layer 5 and above:
Layer 4:
G1 E-1.0000 F1200
; layer 4, Z = 1.170
G1 E-1.000 F1200; Stop extruder
G1 F9000 X114 Y62; Move to snapshot position
; feature outer perimeter
G1 Z1.170 F1200
G1 X12.746 Y-7.350 F4200
G1 E1.0000 F1200
G1 X11.678 Y-8.949 E0.0940 F741
Layer 5
G1 E-1.0000 F1200
; layer 5, Z = 1.470
G1 E-1.000 F1200; Stop extruder
G1 F9000 X114 Y62; Move to snapshot position
G1 Z1.470 F1200
G1 E1.0000 F1200
G1 X13.349 Y-6.421 E0.0927 F741
You can see above that in layer 4 "G1 E1.0000 F1200" occurs after the position change "G1 X12.746 Y-7.350 F4200"
But in layer 5 "G1 E1.0000 F1200" occurs before the position change "G1 X13.349 Y-6.421 E0.0927 F741"
This results in the head moving to the desired position to take the image, but after layer 5 it begins extruding whilst moving back to its next location and I cannot seem to find a setting in simplify that would influence this.
Can anyone think of a reason why ?
regards
John
