Fehlmann Picomax 100 Retrofit

Wow many thanks I'll give it a try.

Didn't tacke the encoders yet, but closes go the control panel:

I tried to tackle the encoders today and found something odd, even with the corrected color code i can't get a signal.
then I tires to mesure with a multimeter. and all the signal were high even with no wiring present. is this normal?
thanks Patrick

Still no solution for the encoders, H hipe it's just s Iron jumper and no damage in the Mesa board.

But I added a mount for the hand wheel.

and the panel is painted and wired up. After some testing in halshow I can edit the hal files now

No progress in the last weeks.
Still struggling withe the glas scales and the spindle.
For the Spindle I might have found a solution in form of a 7.5 KW 8000rpm servo with driver from china. This would also solve my encoder problem for rigid tapping. And I can use the analog input from mesa for spindle load. But it's an unplanned investment.
The question is how much do I get for the old spindle motor and drive to ease the pain a bit.

It is not clear what you are measureing with the multimeter. You really need an oscilloscope to look at the square wave signal which should be coming out of an encoder. I made one of those €20 toy kitself osci from DSO-Shell,  and it is really handy for this stuff.
