3.2-RC1 "Error: Attempting to extrude with no tool selected"

[oliof]

Duet3 with SBC and toolboard running 3.2-RC1. During a simulation run of a gcode file I get repeated errors "Error: Attempting to extrude with no tool selected"

If you do not select a tool in the start G-code of your print and if you do not have a tool selected before you start the simulation, this error message can be expected. RRF needs to know the print tool during a simulation in order to work out the extrusion times.

If you somehow select the tool in the start G-code, please share the file.

@oliof That'll be because you haven't selected a tool. If you only have a single tool, then the simplest thing to do is put T0 somewhere in your config.g file. If you have multiple tools, put T(n) at the start of you slicer gcode to select whichever tool it is that you want to use.
