FlashForge Creator 3 Reference

Here's some useful information that's not clear when operating the Creator 3:

• Z Calibration Expert Mode:
  • ZCAL: Extra distance from right nozzle to bed zero.
    • Positive values mean the right nozzle is lower than the mechanical "zero" point and is too close to the bed.
    • Increasing to be more positive adds more gap between right nozzle and bed
  • ZDIFF: Offset of left nozzle relative to right nozzle.
    • Positive values mean the left nozzle is lower than right nozzle.
    • Increasing to be more positive adds more gap between the left nozzle and the bed when that nozzle is active.

prusaslicer-flashforge's Issues

add script for parsing fp5 generated gcode to find supported gcodes

have it print out supported gcodes that are not in the whitelist implemented in #13 and also any comments in the code or unhandled lines

Check for unsupported gcode

create a whitelist of valid gcodes/gcode usages and throw an error when an unsupported one is detected in post process

Deduplicate print profile configs (soluble vs non-soluble)

PrusaSlicer-FlashForge/FlashForge.ini

Line 383 in e26eefc

; TODO: Use Inheritance here to de-duplicate settings

Post Process fails on missing keys

ex. if no filament offset is parsed from the custom gcode blocks, then it crashes

Rendering issues with Flashprint5

Looks like some layers are being detected as 0 layer height?

Prime All Active Extruders

Currently only the first extruder is primed. All Active extruders should be primed (Inactive one first). Alternatively, keep it as only priming the first extruder and use a wipetower (needs a hack to get relative extrusion distances to work on ffc3)

Extruder may heat even if not used

PrusaSlicer-FlashForge/flashforge_post_process.py

Line 232 in d7d9060

# TODO: strip out heating code if one side doesn't have any extrude commands

Delete any heating code if extruder is:

1. the "UNUSED" fake extruder
2. not ever switched to, even if the profile hasnt selected unused

in scenario 2, it should emit a warning in the PP script

First Layer Travel Speed

FP5 has a default first layer travel speed of 70mm/s. Prusaslicer doesnt support this. this causes issues when printing first layers as the wipe speed is based off of the travel speed and too fast of a wipe on first layer will rip small features off the bed. These wipes happen even if wipes are disabled.

2nd Extruder not reheating after pause from touchscreen

possibly related to missing comments in gcode that flashforge expects

Support Mirror and duplicate Modes

need to post process m118 in startup code and also set M109 based off of mode
