Fehlmann Picomax 100 Retrofit

Damn I looked at the external offset samples and I think they are made for something different. They result in an actual movement of the machine. I could invert the signal, so the machine tries to keep the quill in the same height when the column is moved.

At the moment I don‘t know how I can use an encoder feedback from the column to enhance the capabilities of the machine.
But it is not essential to have the feature to get the machine running. So this will be postponed.

the Mesa boards are still stuck in customs, so I took the time to bring my Ideas from cardboard to CAD



in the void right to the computer will com a 3d printer holder for the programmable key pads.
​
Found some 150x12mm aluminium in the shop which I can use for the computer and will be bolted to the existing quite beefy aluminium frame.
​

​
in the next days I will prepare the aluminum parts. The cover I sent out for laser cutting out of 3.2 mm aluminum plastic laminate stuff. I the end this might look rather professional compare to my other retrofits (But I am quite sure I find a ways to make it look trashy)

Not much progress over the last time.

but I printed a sheet to mount the USB ports in and the switch for the control power.

the keypads arrived and I printed a carrier to later mount the on the interface​

 

Monday I can pick up my mesa boards, the all the hardware, except the laser cut sheet and the hand wheel has arrived. 

 

With the Mesa boards ready for pickup, I found the motivation to make some progress and made the monitor mount.
This took longer than expected cause the reference switch on the Y-Axis got stuck. But after a some massaging the old machine worked again

The control power supply got a new breaker with an integrated ELCB. Wich is also providing power to the socket on the control panel.

the I Installed the New 24V and 5V power supplies

last step was preparing the din rails and wiring channel for the mesa boards:

Thats all for today.

Cheers Patrick

time to bring everything to the machine...

found the time this weekend to finish the control power switch:





this was the last step needed to mount the computer. So I installed the mounting bracket 



and then the computer:
