Fehlmann Picomax 100 Retrofit

Looking good

Is that a Siemens DC motor?
It looks very much like what I have on my machine, I hope I don't need to replace it.

It's a DC motor but not Siemens and I am replacing it I have a 3 Phase servo here. Which I hope will fit nicely.
I had some trouble with the drive unit and needed an encoder to run with linuxcnc. So I decided to change it.

Today was motor swapping dayToday was motor swapping day

I kind of have trouble editing and pposting pictures.
anyway the motor is swapped. and with no running cnc I realized hi nice big lathes are

nest is to swap the driver. and give it a test.

Long time not progress here but I managed to mount the VFD into the cabinet:

rest ist to wire it up. But there is the question. Using the analog control or using Ethercat?
Ethercat would ease the wiring quite a bit. But how to manage?
I have no clue yet. And can I dress the Mesa Card and the Ethercat device fro the same ethernet port? DO I need a switch? I can I connect the VFD to the computer and the Mesa board to the 2nd port of the VFD?
This would be great, but I am afraid the world is not that simple...

long time no see... the reason was simple I didn't make big progress.

but now some mentionable steps are done...

The spindle motor and VFD ist wired with own contactor an breaker, ready to get powered on for the first time and get its parameter.

removed some bug in the wiring, this took some time.

I switched the old column control (was not working) to a new solid state reversing contactor and let linuxcnc control the brake in hal

and now it's moving by it's own power:
