Cura in Astroprint is Producing Different Output from Cura Desktop


#1

I am trying to use Astroprint to slice prints for a Monoprice Delta Mini. Unfortunately, the Delta Mini is very sensitive about the flow of the plastic on the first layer. Basically, it is difficult to get a solid first layer on this printer. I have succeeded in finding settings for Cura 4.0 that work consistently and have attempted to transfer these settings and also the start gcode to Astroprint cloud.

Unfortunately, I have been unable to get Astroprint cloud to produce the same gcode. Specifically, Astroprint cloud is extruding significantly less filament when printing the brim which leads to failure since the print will not stick. If I use a raft it does stick — barely but then the rest of the print seems to be under extruder.

When I first defined the filament it defaulted to 3.0. It also seems as if the slicer still thinks the filament is 3mm thick instead of 1.75mm.

I would be happy to provide the gcode files if this is helpful. Here are a couple of lines showing the issue:

Astroprint — Notice the initial extrusion is for E0.00914
;LAYER_COUNT:175
;LAYER:0
M107
G0 F3600 X-13.607 Y-2.25 Z0.21
;TYPE:SKIRT
G1 F1500 E0
G1 F1800 X-13.567 Y-3.042 E0.00914

Cura 4.0 — Notice the initial extrusion is for E0.02423
;LAYER_COUNT:175
;LAYER:0
M107
G0 F3600 X-13.607 Y-2.25 Z0.21
;TYPE:SKIRT
G1 F3000 E0
G1 F1800 X-13.567 Y-3.042 E0.02423

I am soon this is just user error but if you could point me in the correct direction that would be great.
