I got the Haas keypad off a site on the internet that sold replacement parts for Haas machines for a bit cheaper.  It was $250.00 for it back when I bought it a year ago.  I did a google search and couldn't find the site I bought it off of.  They sold other haas parts as well for cheaper than going thru Haas.  I was curious if anyone on here has removed the X axis table on one these machines.  The ballscrew has .0025 of backlash in it.  It's not the thrust bearing so It either needs reballed or refurbished.  I just can't figured out how to get it out.  I got the 4 bolts out that bolt it to the table from underneath.  But it's also doweled in and won't come down off the dowels.  Any help would be greatly appreciated.  I search all over for a maintenance manual and didn't find anything.

I'll put the movie and pictures on tomorrow as I'm going to have to edit it and make it a bit smaller to post on here.

Ya I would say I got about 4 months of time invested and about 10k so far.  I was no master electrician when I started this there was quite a learning curve to take on a task like this.  I didn't work on the machine for awhile due to some personal reasons in my life but recently took it back up and plan to see it to completion and start getting some of that cash invested back out of it .  Or that is the plan anyhow!  If I could give advice to someone trying to recreate this I would first and foremost inspect the ball screws of whatever machine your getting(if this is possible under your situation)  I love the Teco servo drives.  I'd recommend them to anyone.  Make sure you don't ever tap on the back of the servo motor.  Like when your putting pulleys on .  I completely changed the breakout board(to CNC4PC's  C32 CNC Board) and most of the control components in the back to get some noise immunity and reliable stuff that was more easily replaced.  By this I mean using the previous boards I had to build a line driver board so the breakout board could speak to the servo with noise immunity from using the 2 wires versus the singled ended wire coming from the breakout board.  I also learned that actually grounding the shielded cables is super important and having a good ground near the machine is nearly essential IMO.  I would also suggest for a possible retrofit project that you buy some new wires for all your devices to be hooked up.  As in kind of plan what gauge wires your going to need and order some reels of shielded cable in the correct sizes that you'll need.  I dug through and reused a lot of the older wires but it would have looked more professional and uniform had I done that.  The servo drives and VFD have a descent book to go with and to a first timer this can seem overwhelming but you just got to take the time to read through see what options you have and get them set correctly for your situation(parameters and such).  I ran a Haas at my work so I decided to figure out the keypad matrix on Haas keypad.  Just so I could bring the Haas feel back to home.  If any1 would like the matrix table I'll put it in an excel sheet.  I'll try to take some new picture of the back cabinet as well and post it up tmrw.  I read through JHChopper's retrofit and try to closely mimic what he had done.  A big thanks goes to him as well or I wouldn't have felt at ease at trying to retrofit this. I have a video of it cutting I'll post up.  This was it's second test piece so I had pretty slow feed rates especially on the plunge.  As my confidence in the machine increases I'll move to a more productive level. Happy Holidays

So I had begun working on my machine again about a month ago.  Everything is wired and works fairly well I still got to do some servo tuning.  I haven't yet hooked up the toolchanger but it's the next thing on the list.  I got the haas keypad hooked to the pokeys and I have mapped about 70 of the buttons to their respective button presses in Mach 3.  Here are some pictures.  I completely changed my control cabinet compenents as well to some more expensive and reliable electronics.  I have a couple pictures I'll put and maybe I'll take some more if anyone's interested.

Thank you very much for your response.  I got the brake working good now and all 3 axis move as they should.  I ordered the spindle drive and it should be here late next week.  My next concern was the air switches for the tool changer.  What are there power requirements?  110 ac 220 ac or 24vdc?  They appear to be Ac from what I can tell but don't want to burn them out as Im sure they are hard to find.  When my machines up and running I'll repay you with a free job for all the generous help.

Did quite a bit since I last posted.  Changed the motor plates so they match the new Teco Servos.  I wired up a couple more things in the electrical cabinet. Then made 3 line driver boards and also intergrated the brake circuit into them.  I called about which pin it was for the brake output they told me it was pin 45 but that doesn't seem right.  So waiting on more info before I modify 1 of the control wires I bought off them.  More pics soon as I haven't post many lately.

What pin did you use on the Teco servo drives to disengage and engage the Z axis brake.  It speaks about a break output in the book but doesnt say a specific pin.  I look though the CN1 and didn't see a brake output.  Any help would be greatly appreciated.  Thank you!

Disregard that last post.  I had everything hooked up correctly I forgot to send 5v to the enable on the breakout board.  After I did that everything worked great.  Thanks

Been working alot lately and haven't had much time for the machine.  I got some free time recently and tried to get the servo interfaced to the PC.  I wired the servo motor and connected the encodered and powered it on.  Everything worked fine it shows the position if I manually move the shaft of the motor.  The SON(servo enable) was off at this point.  I then enabled the servo on that worked fine and it jogs fine if I use the Dn-05 menu on the driver(manual jog).  The problem Im having is it doesnt seem to see or acknowledge any input from the PC.  I bought the line driver SN75172N.  I made up a breadboard test circuit for this.  I used your e-stop and enable circuits which both work as expected.  So everything is working except it don't move via the computer.
