Re: [Emc-users] Mesa card help
Why would you go though the trouble to redact the company/machine name on the drawings? Whats there to hide?

Nothing to hide, the control is a Protrak. The company name is Southwestern Industries. It probably is no big deal now, but I decided to hide it because a box on the corner of the print says not to reproduce it. Thanks for reply, I will get the computer up and running today.

Re: [Emc-users] Mesa card help
I did a somewhat similar machine (+-10V amps, encoders) with similar Mesa hardware with some documentation here: http://code.google.com/p/sector67-sandbox/wiki/ProjectSheetCake Getting the machine to move under control should be fairly straightforward. Integrating the limits/estop and servo enable can be a bit more work, depending on how you want to do it. I prefer a hardware estop, which can require slightly more integration work. You'll also want to determine if your servo amps are running in torque mode or velocity mode, as how you tune the PID control loop will be different depending on that. In my opinion, pncconf will generally be your friend, but spend some time getting comfortable with it and reviewing the actual hal and ini output files to better understand what it is doing for you.

Re: [Emc-users] Mesa card help
Yes the motors have tach's. Everything does work now, but upgrade is needed because of antique control. The encoders are Heds 9000 series with 500 cpr. Each one has 3 green wires to ground, three red, and 3 black. I will trace, more clearly mark the wires, and take photos. The x and y encoders are driven by a wheel that contacts the machine's moving table. Protrak used these for years. I plan on changing the encoders eventually and mount either to the motor or ball screw, but I would like to see if I can get the axis to move first. -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

This looks very much like a lot of '80s machines people have retrofited with our hardware. BTW, you might get more responses to your question if you mentioned the actual machine name. If all the drives are OK, It should be fairly straighforward (having the drawings is very helpful) but there are a lot of details. I guess I would start by installing LinuxCNC on your intended target PC (download the LiveCD image and image-burn a CDR). The Getting Started Guide: http://www.linuxcnc.org/docs/EMC2_Getting_Started.pdf will help with this. If the target PC works OK and has decent latency ( better than about 50 usec is fine for this servo machine), a next step is to install the hardware (5I20 in PC, 7I33TA connects to 5I20 P2, 7I37 connects to 5I20 P3) I would decide at this point if you ever want to restore your old control. If you do you will need quite a bit more work with connectors to allow swapping controls. Beyond this I can try and guide you step by step in what I would do. and perhaps someone with a similar system will chime in. http://s1048.photobucket.com/albums/s375/JoeNoduh/ -- Peter Wallace Mesa Electronics -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
