F3600 feedrates removed from GCode Start Script
Quote from Matthew Ickstadt on 2022-01-26, 17:29CraftWare Pro v1.1.3.301. CraftBot FLOW IDEX with latest firmware.
When the GCode Start Script is set to the following:
G0 X0 Y140 F3600 ; go to purge position
G1 E20 F600 ; purge filament
G0 X30 F3600 ; wipe
G0 X0
G0 Y145
G0 X30
G0 X0
The output GCode file removes the X0 and the F3600, probably thinking they're redundant. However when this is printed the actual feed rate is 1mm/s.

Changing the line to `G0 X0 Y140 F3601 ; go to purge position` causes it to be output properly.

The CraftWare Pro facilitates a postprocessor that eliminates the redundant parameters to get a more compact GCode.
This is actually a nice (and pretty unfortunate) catch. The initial feedrate state of the simulation printer is F3600, so it thinks it is redundant for the first command too - but the actual printer does not have the same initial values. If you had chosen any other value, it would not be eliminated 🙂
We will fix it.
Until that use any other Feedrate than 3600 for the first command 😀 After the first non-F3600 movement everything will be fine.
Best Regards,
András
