Thank you.

One more question. does the M207 command need to be sent after the tools are all created?..

I'm still getting the issue that the retract gets reset to 2mm whenever I start a new print from the "initial" state.

my custom gCode for PrusaSlicer at start creates the per color tools and after they start being used M207 command returns 2mm for retract amount even though I'm setting it in the config file to 0.5mm

Please share your full config.g you slicer start gcode and any macros you call in it.
Also the results of M122 and M98 P"config.g" please.

M104 S[first_layer_temperature] ; Heatup and Purge Nozzle
G92 E0 ; reset extruder
G1 X0 Y0 Z10.0 F5000 ; move to purge position

T0
; bring it up to temperature

M116

; machine standard purge - purges all nozzles on the left side of the platter.

; set up the tools for selected colors.. You can define as many as you want,

Also at the end of a print, custom gCode is:

; remove the extra tools so we restore back to standard
M563 P3 D-1 H-1
M563 P2 D-1 H-1
M563 P1 D-1 H-1

M104 S0 ; turn off temperature
G28 X0 ; home X axis

M140 S0

M84 ; disable motors

What's in M98 PPrint_Start.g?

nanoplane

@Phaedrux

print_start.g

If you send M98 Pprint_start.g on it's own do you get any errors?
If you send M567 during the print does it respond with the expected mixing ratio?

Have you enclosed the macro name in quotes as OwenD suggested? ""

I get no errors
Hmm sending M567 returns nothing... But it does mess up the mix ratio for the current print.. until the next tool changes.
sending M567 P0 (P1 P2 P3) returns the correct mix ration for each of the "tools"

The print_start.g on it's own doesn't work unless I've preheated the bed and the nozzle... but once that's done, print_startg works fine.

Could it be because I'm redefining Tool 0 in my custom gCode forcing it to default the retraction settings??

nanoplane

Yep, that's it....

Recreating or adding a new tool sets the retraction to a default value of 2mm..

So I need to add an M207 S0.5 F1000 Z0.2 command to my custom gCode after creating all the tools...

cool.

Phaedrux

Glad you figured it out.

It's a feature
