Retrofit of Precix 5x10 CNC

Randy!
I think your vacuum system was modified before you became the owner of Precix.
I attach a photo of the original control of vacuum pumps.
There are twelve (AMETEK lamb electric 116312-00 ) vacuum pumps (mine are now removed for maintenance). Four of them are connected to the holes one to one. The other eight are two to one hole. (See the appendix.)
This is controlled by six switches. One switch to two pumps, how they were connected in the original I do not know.
I have holes on top of the table in the sacrificial material not drilled and I can't check which hole is responsible for which part of the table (yet).

For good holding down, it is not the power of the vacuum pump motor is important, but its air performance. Original pumps have an Air flow 50 l/Sec that means: 50*60*60 - 180 m3/hr. Total 180*12 - 2016 m3 per hour (Vac 133 mm H2O). I suppose you need a more productive vacuum pump.

OMG! I saw a picture of the Precix Servo Controller USER MANUAL v.99f ! Do you have a scanned copy? It would be very helpful to me.

Thanks again for your respponse.

Unfortunately for me user manual ( www.precix.com/bill/manual .zip) containing the vacuum system data is no longer available. There is an incomplete Html copy of the user manual on my Precix disk. Only three sections. Maybe someone has a complete copy of the user manual on a disk or a precix (QNX) disk image? 

I'll scan everything I got here - just give me some time. I think it's out of order, but I'll scan it all and get it to you today or tomorrow.

Sorry for the delay - I got my shoebox of papers scanned...

Sorry for the upside down papers and out of order documents. I meant to get the sorted, but I didn't want to wait any longer!

Thank you, Randy!

Hello all!

First i want to give big THANKS! to Randy for giving all the infos of his precix retrofit!

We also have an Precix mill (almost the same config as Randy's running since 2000 at our university department (Art academy in Austria). 
Mechanically we ran through many repairs/fixes during the last years on our own as we got no support from precix. Mostly we suffered from UNC part supplies in europe, so the mechanics turn more and more into metric

Thanks to Randy's posts we were encouraged to give our old lady another chance to stay in our workshop, as our controller went down 2 years ago.
So far we go the same track  with mesa 7i77 and 7i92  (just shipped)... and i am super eager to get it running again.

So far we have no major issues, thanks also to linux cnc and the forum! ... but i would be very grateful if you guys could help me when stuck with the project.

Best wishes from Austria,
Armin
