Boxturtle retracting a bit too far on tool change | ArmoredTurtle 3D | Page 1

I got my box turtle mostly working, but when a tool change is called it retracts the filament just a little too far before feeding the next filament. This is causing the AFC plugin to lose the lane since the initial filament is no longer in its lane extruder.

Is there a variable i can set for this length?

I have run the built in configuration for all the lanes and the Bowden length.

I'll get the debug command in a reply here shortly

2 likely scenarios

your tool_unload_stn is way too long
that value is too small and it is doing it twice and then over shooting your hub and then load sensors

so yeah the log files confirm its unloading twice, try increasing that distance

Sorry for the delay, haven't had time to get back to this.

I tried upping the unload stn to 105.9, but still getting the same behavior
