Re: EMC2 Screw Cutting Problem

Steve.
I've created a new configuration with the wizard and added the 'setp
encoder.0.position-scale 48' instruction to the Custom HAL, as per
your reply (copy kept of previous config). Doing this seems to put me
back at the "system waiting forever" stage when running a threading
gcode file. Do you think there could be something else amiss with the
wizard, such as selecting the wrong kind of spindle encoder
instructions for my particular setup?
Sorry to be a pain with this, but I do appreciate your help. Thanks,
Martin.
