Thanks for this info. Has anyone implemented spindle load monitoring per tool like the Haas control? What would this take, adding a line in the tool table plus some tweaks? On Mon, Oct 17, 2016 at 11:03 AM, Stuart Stevenson wrote: > You can find explanations in the

You can find explanations in the documentation HOME_OFFSET =0.0 - the amount you want to table to move from the homed zero position after the index pulse is found and the encoder position has been set to zero. You don't necessarily need to know exactly how this

I still don't follow though, how mesa hardware uses the index. Does it zero it the first time, or how does that bubble up to lcnc? On Mon, Oct 17, 2016 at 8:18 AM, andy pugh wrote: > On 17 October 2016 at 12:59, Erik Friesen wrote: >>> The "bldc" component
