Conditional on G29 S0 or S1

Stephen6309

Conditional to do a G29 S0 if heightmap.csv doesn't exist.
RepRapFirmware for Duet 3 MB6HC version 3.1.1 running on Duet 3 MB6HC v1.01 or later (SBC mode)

Something like:
if heightmap.csv exists do G29 S0 else do G29 S1.

Tried searching and got nowhere.

you could perhaps use the exec on mcode thing and have the pi check for the file and in turn execute some gcode from the pi's shell?

I haven't tested it, but this may work:

G29 S1
if result > 1
  G29 S0

G29 S1
if result > 1
G29 S0
When I deleted the heightmap.csv:
G32
Error: G29: Failed to load height map from file heightmap.csv: Could not find file '/opt/dsf/sd/sys/heightmap.csv'.
35 points probed, min error -0.170, max error 0.168, mean 0.000, deviation 0.089
Height map saved to file heightmap.csv

After a system page refresh, it's there.

Then I changed it to:
G29 S1
if result > 1
G29
It works with no errors

I was just playing with this.
Since I have a heated bed and also use the filaments/config.g to set different bed temps depending on the filament loaded - the bed heights could vary, but I haven't really seen that in real life. With that being said, I always do G29 with the bed heated to the filament's config.g settings. So depending on the different filaments in the DWC profiles, bed warp-age could vary - so not one bed height.csv for all. Hence this:

G29 S1 [P{move.extruders[0].filament^".heightmap.csv"}]
if result > 1
   G29
   G29 S3 [P{move.extruders[0].filament^".heightmap.csv"}]

Will yield:

G29 S3 [P{move.extruders[0].filament^".heightmap.csv"}]
