Thanks for the replies guys, i just decided i would make more progress reading than tlooking for problems i do not know the answers to..i purchased their medium lathe conversion kit, it came as complete unit..i knew that in the long run i could have probably have put one together myself for cheaper, but needed to be running asap...hindsight 20/20..it came with a computer and mount, HiCON motion controller (they call it the apollo3) , Teco 750 watt servos & teco servo drives. this is my first cnc setup. the motion control chips are in the Hicon..if i were to go through and set up ports & pins etc. up as specified in the manual , the relay & contactor wouldnt activate. everything is wired up EXACTLY as specified in the diagrams sent with the cpu.  I have been through everything the last few days and have got to the point where everything works, but when i try to home/set home i get an error..im going to re-read and take notes from the manual again to see what i can get. one thing that would help me now is if someone can tell me how to get a backup re installed....i did it a few days ago ,but with everything ive read in the past few weeks it escapes me now. thank you to any and everyone who replies, i desprately need help, and aside from the initial cost ive ive lost more money than you would believe from the extended time being down.

Hi Telco:
You might try posting in the HiCON section. Your post regarding this controller is only the second one I have seen in the forum, the other one being by Mike in the HiCON section. One possible cause of computer/board communication could be the Ethernet cable. On my dspmc controller, the other board made by Vital Systems, before they produced the HiCON, the cable must be a "Crossover" type, versus the standard 1:1 correspondence.

Hi guys , thank you all for the replies. I have made good progress since last post, but do have a few hiccups to work out. And before I say anything else I do want to thank mach motion, all in all they have been a huge help, and the tech support has been great. The problems I've had are more related to mach3 than anything machmotion has done.  The thing is , I don't want to just get things working, I would like to understand why and how,  so i  can troubleshoot any problems myself. When I thread using the wizard , or with the G32 coded line by line, the pitch of the threads is off. It will cut uniform good threads , but if I command a 24 tpi (.04167) I get around a 20 tpi..have tried numerous spindle speeds, always same result. The steps per rev is correct. The encoder on my spindle gives 1000 pulses per rev, is a 1:1 ratio, and maintains stable speed when threading indicator is lit. If I set to thread at a certain rpm, and the true speed is different, should I plug this number in for the speed? I've read the thread titled G76 threading issues, and experienced the same issue of the very slow movement at the end of a pass,  and added G95 to the initialization string, and it solved that problem. I occasionally get an error that farces the program to close, and i have seen a blue screen several times , but the computer recovered quickly. Also, when i open mach 3, i get one of 3 load screens that come up, a blue/ white mach3 , a red / grey  art soft, or a screen that says mach 3 professional etc etc, has some graphics, and appears to be the one i should get...oh yea, I also want a partridge & a pear tree!

Yessir, the forward/ neutral/ reverse gearbox for the leadscrew turns at a 1:1 ratio with the spindle, and with the gears removed that would run the leadscrew i was left with the perfect location to mount said encoder. I've attached a pic, if it doesn't post I'll get one up in a few min.
