RRF Config

Dizzwold

Finally got around to setting this up, well the config anyway.

In the RRF Config Tool, when I set up the Bed Mesh Compensation, does this take into account the Z probe X/Y offset I've already quoted it, or do I have to account for it in my measurements?

Regarding setting up an emergency stop button, a mushroom press to stop, twist to release N/C Button. Do I connect it from 3.3v to gnd on my chosen i/o connector, and therefore does the following match what I want it to do, i.e. to stop everything at anytime until released;

; Emergency Stop
M950 J1 C"io4.out"
M851 P1 T0 S0 C0

I'm relatively new to Duet so I at-least want an emergency stop, just incase my config is wrong.

I'd be grateful for your input.

You have to account for them.

For the emergency stop you wire it between the io.in and ground.

@dizzwold for the stop button, see https://docs.duet3d.com/en/User_manual/Connecting_hardware/IO_E_stop

For the bed, you don’t need to offset the mesh, just be aware the probe may not be able to reach some points close to the edge. Eg if your probe is offset from the nozzle +20mm in X, and your nozzle can’t move beyond X0, you can’t probe any point in the range X0 to X19. The firmware will tell you if a point is unreachable, and carry on with the ones it can get to.
