While I am waiting for my C11 board and my Pixie board, I have started to clean up and paint the mill. I realy, realy hate painting. To do it right it takes longer than it took to make the part. I am not doing the complete smooth and bodo, sand, sand, sand, primer, sand, filler, sand, sand, paint, paint, paint, color sand, polish process. I am doing just enough to clean up the machine and slow corrosion.
I have all of the Allen Bradley control system removed except for the original +5v, +-15v, +24v power supply. I turned it on and the 3 Servo Dynamics driver boards still worked! I did find that the 24V output was only delivering +8v. The power supply manufacturer was still in business and was failure with my power supply when I called them. It turns out that in order to properly regulate, the power supply needs at least 10% load on the +5V output. The only +5v was the Allen Bradley computer so now there is not load on it. I purchased 4-5watt, 20 ohm resistors to put across the +5v to give it some load. I will know this week end if that works.
I thought about scrapping the power supply and buying something more up to date (the manufacturer wants $450 just to IRAN it), but the servo drives take +-15V and it seems that most modern power supplies are +-12V. I would also like to have the +24V so I can reuse all the 24v relays that are already in place.
