Hi Radu
This should be possible with an Ardueno or similar, but regrettably i can't help with that, if you do a search for Ardueno stepper control that should get you a result.
I had a similar problem with my Robland combi and opted for the Felder digital handwheels that i now in use on the thickness planer and the Spindle.
Don't know if this will work on your setup it depends if you have a Metric screw on the table mechanism. I had to make a 2 to 1 gearbox to get mine sorted, Robland had a 4mm pitch screw but the Felder Dials were 2mm per revolution. obviously the Ardueno method is a better option.
Regards
Mike

I'd +1 that as a stand-alone solution - have a calibration point using a proximity sensor for blade position to give a known position (or just a general "Set 0" button), then an alphanumeric keypad and display (and the software that sits behind it all) to drive a stepper/driver. All very do-able. Question is to OP as to whether that's a project he's willing and able to undertake.

Hi Doddy.
This is what I had in mind. A proximity sensor for zero-ing the blade before each command, and a keypad, to imput a measument and hit enter. I am sure it is very do-able, for the people who know how. I am not one of them. :p Btw, I would very much prefer to not have a pc included in this equation. There is some will and some ability to put in practice the project. The "how" thing, it's a whole other story.

Hi mekanik.
The mechanism that raises the blade is the one in the photo. . The machines were build here half a century ago, so I believe all is metric.
The thing that bothers me when working, is getting on my knees to see the ruler indicator on the thicknesser and to position a metal ruller next to the blade when cutting tenons or other similar stuffs on the table saw. I had in mind the stepper motor approach, because a couple of years ago, with the assistance of some very patient guys on this forum, I managed to build a cnc machine, so I know a bit more about this things, rather than arduino. But it is on my bucket list to learn arduino, and conquer the world with an army of tiny drones..whuhaha. :P
