Great I'll do that tomorrow I work 3rd shift so my saturdays are wasted sleeping. Tomorrow is my only day to do anything at home.
here are the pics. let me know if they don't come thru.
the second pic is the one box that has nothing going to it I'm not sure if it is part of the kit or the old parts not used anymore.
That an OPTO board for the input/outputs, I would have thought that would have been retained, as these can be interfaced with the new system.
But I guess with no connections on it, they just left it in place?
Was this a retro-fit half done maybe?

Well by half done do you mean it's there and not working correctly or it's not all there? When I took ownership this is how I bought it. It only came with one manual so I have very little to go by. I don't know what all there kit comes with but it seems to be working somewhat and I wouldn't say it's working fine by any means. I'm still not sure what 2 wires I could try and switch but that drifting problem might of went away by itself. Should I take all the encoder green ground wires and hook them to a cabinet ground this is not done with any of the axis? Thanks so much for your help I'll try not to be to big of a burden.

The two wires I mentioned do not apply anyway as by studying the pic, they used single ended encoders anyway, which is not as good as differential type.
It does not appear that even shielded cable was used, so grounding the green would not achieve much.
I am not that impressed with the wiring, looks like it was strung in a hurry!.
The OPTO board I mentioned is not wired, so I assume it was left from the original system.

I agree on the condition of your refit. That machine ain't got a snowball's in in **** unless you redo it right. it also takes a lot of study to learn camsoft.Originally Posted by Al_The_Man
I "learnt the hard way". Single ended encoder are nothing but trouble. You've already seen it. Also, you're using the Galil and ICM2900 to try and fire your outputs to run your spindle. The setup you got don't work. BTDT.
The best route for I/O is an Opto22 card in the PC and IO boards. You've got an Opto22 board that's not connected but i don't recognize it.
In short, you got to backup and regroup if you want a good Camsoft machine. Or, hire somebody to do it for you.

using my powers of deduction I would say the machine retrofit went something like this....
1, original control went FUBAR
2, machine was otherwise good so a retrofit was in order
3, camsoft seemed like an easy way to get the machine back on line
4, as most of us know implementing a retrofit can be much more of a PITA than one might initially think
5, after a very frustrating experience of getting the machine to barely work it was decided to put the machine into production without some features like tool changing ( ie: doing whatever it takes to make some money with this thing )therefore the opto 22 relays were not used
6, after using it for a while the machine was replaced with something that worked
7, now it's your problem

Well Ben it's a long story but the only thing you guessed right is thats it my problem now. I just need to learn more about machine refits then I'll be fine. I pearsonally would not of chose camsoft but thats what it has and I know I'm not stuck with keeping it, but I'm sure when I get it working right that it will do everything I need it to so I'm soildering through with it.
