Fehlmann Picomax 100 Retrofit

Later printed out the spreadsheet for relocating the old wires



then it was time to start the wiring by mounting the mesa boards to the din rails



in the end I was able to rewire the first three connectors.



and the 5V power supply is ready, but while doing this realized that the spindle has no encoder, I didn't know how that could slip my attention, at the moment it uses an analog tachometer for feedback to the VFD. So I have to figure out what I will do about it.

Inputs are done, analog Outputs and some of the digital outs. But more to come

You should change your name from begginner to PRO!

On many stages I am still a beginner, but with the third retrofit comes some experience and confidence. Still struggling with python I don't really know why.

Today I finished the IO's, now only the encoders are missing. And I need to clean and wired the 24V circuit.
And I want to add a main voltage monitoring relay, cause I can switch control and three phase separately. And I want to get an information when I power on linuxcnc and don't have main power on. This will be used after I finished testing.
Looks almost clean now.

FYI, all mesa boards with VFIELD have monitoring for it, i had it shown on a VCP panel on all my retrofits.

The 24v are not the issue, but good to know. I am manually switching 400V main power separate from the control power. I just want to see if main power is on.
I usually have main power off while making changes on the vcp. This way I can test most of the functions without it actually moving
