Its a mute point anyway as I will not be changing the configuration. As I have tried to point out this is not my first rodeo I have owned other CNC machines over the past 15 years.   This is my first Mach3 one however that is why I am here. Thanks.

So from what I understand Mach3 knows when you Home All the switch is now a Home and instead of stopping and faulting it just reverses.  So when the Home sequence is started the Z if first, then Y and then X. I do not see an issue. If your Homing the machine your sitting or standing right by the machine if it screws up the its E Stop time.  When the Homing is complete then it goes back to the limit mode.  My other commercially built router did exactly the same thing it was not a Mach control system.

Its working fine, Home all works as I combined Limit  and Home.

Yes its up and running now.  Got it doing a test file, the one with lots of movements, especially Z's.    Windows XP not the easy set up for a Network but it got done.  I did set the pulse Frequency at 25,000 so I would not need to retune the motors and the OEM settings I had in Mach3 work just fine.  When the file gets done and it seems to be a lot faster, maybe.  I will do the permanent install, thanks guys!!  (Gals)   Yup its faster, old parallel port running Mach3 40 minutes, new UC400 running same file 24 minutes and the motors are a Lot smoother.

The screw terminal connector should have been in the box, seems like a mistake. I'd ask Cncdrive if they can send it out if you can't get one locally.

There's a lot more electronic suppliers than Radio Shack. If you want the connector quick, ask on an electronics forum (and on the Cncdrive forum) if they recognise the connector and google for any electronics suppliers near you.

Documentation is in the UCCNC folder after you do the installation. The user manual is also available for download from their website.

 There are NO electronics suppliers in this area, and mail order its usually a shipping charge that exceeds the cost of what was ordered. I finally kluged together some pins and got it powered up and set up in Mach3, I have yet to try.  One of the support staff from where I purchased answered my email and is sending me the proper connector.  Thanks for the reply!!

I did get the UT400 ETH controller yesterday and have yet to try out. Zero doc's or paper came with it, no required circuit board connector to parallel port, no way to connect power via screw terminal, just some oddball plug connector.... not included. Not a happy camper. You would expect for $160 the screw terminal connector would at least be in the box!!  The rest of the connectors and cables I had ordered but they are required for the board to work.  The connector for power??  We no longer have a Radio Shack so If I can not find one in my junk box its another expense.

  Merry Christmas and Hanukah  season!!

So what board did you buy?    You must also realize that getting a CNC system set up requires skills that some users may need to learn on their own, not here.

I've done all that. I installed the script. It was working fine but now it isn't. As for way y axis ways there is no binding. If you unhook the rack you can push it with 1 finger from 1 end to the other with no problem.  There isn't 1 tight spot in it at all. It almost seems like I have 1 lazy motor but they are both the same and new

A broken wire or loose connection to the stepper motor or power supply can cause it to fault out / lose steps.

I have been involved in electrical and somewhat in electronics since 1962 and also air craft electrical.  100% on crimped connections and extra flexible wire.  One other thing, they do make stepper motors that have feedback like servo motor encoders. I looking into it at one time and they were not much more expensive than regular steppers. I will try to post a link if I can find the source.

I have a Chinese 6040 router purchased from Automation Technologies and it came with a wonderful PDF user manual that tells how to set up the touch plate. You do need to copy and paste the VB Script into the button for the AutoZero.  The Script is in the documentation.  I suggest reading the instructions that came with your machine.
