Help needed to get my 7i76E + 7i85S + 7i73 on my mill going.

You might want to let the gear ratios overlap. Maybe 1240 shouldn't require a switch from B High to A low.

With C D E in low gear only I get the whole range from 80 to 2500 with full torq.

But if there is no problems with overlapping so why not. The problem I see is how will LCNC determine what gears are most suitable? Max torq or less torq?

hello tecno,

it looks like your gears are set up by electrical contacts. why you do not allow linuxcnc to take in charge of that through output pins and relays. you chose your spindle speed and LCNC decide which gear to activate.

Hello Pawel, the gearbox on my mill is totally manual. Only sensors on each gear setting connected to 7i76e inputs.

Is this the way for setp?

setp hm2_7i76e.0.7i76.0.0.input-14-max-speed 160
setp hm2_7i76e.0.7i76.0.0.input-14-min-speed 80
setp hm2_7i76e.0.7i76.0.0.input-14-ratio ??????

I'll have a go at it. If its wrong I'm sure it will be corrected by those that know.

The gear max min and ratio pins belong to the gearblocker component.
And then is the question on where the index for the gear will go. I think it is
zero-based, so gear one is index zero. So if my ramblings are correct it could be like
