My old XP computer died last week.  I tried a newer PC with a fresh 32-bit WIN10 and a PCI parallel port, but no luck.

So I bought a UC100.  I thought it worked after a quick test.  I had control of x,y,z on the keyboard. But then when I went to use it this morning, it's not right.
 
On a ref-all-home, it stopped on the Z.  Like it went past the switch.  Someone else said they had a ground issue after going to the UC100.  I'm not sure how to trouble shoot that.

After more testing time, it seems like I need to start with moving one way on X with the keyboard before using Y or Z.  But then is stops after a few short moves and I loose control.  I can't just run a program either - the spindle CW F5 button flashed and MACH stopped at around the 3rd line.

I think I'm close.  IS there something to setup up after moving to the UC100?   This is an old K2 machine.

Looks like I'm in trouble then.  No comments. 

Well I moved to the uc100 a while back when I ditched the xp machine for a win10 mini.  I just had to move the XML file to the new machine and the licence and it just worked. Is yours a genuine uc100?  There are apparently many clones around.

Hi,
if I'm not mistaken a genuine UC100 requires that you install a specialist drive on your PC whereas the Chinese clones rely on the PC's existing USB interface.
Were you required to install such a driver?

You certainly need to install  special Mach3 plug in but no requirement for a special USB driver.  Good support available on the CNCDrive forum.

Thanks.  I'm close, but just not quite.

I did install the driver.  Before that there was not control at all.  Now it is just erratic.

I'll try there.  In the meantime, I ordered a refurbed old PC.  I need to make some stuff for customers.  I had hoped to move to more modern hardware, so basically do it sort of right. I'm guessing I really need a new controller, but that is a whole different level of troubleshooting. I used a machine at a shared shop for some tests.  It was way better.  More industrial, not PC at all.  But it relied on running filed from a USB drive.  I'm thinking of moving to something like that. 

I'll try their forum.  Thanks.

I figured this out.  The USB cable is very sensitive to placement.  I moved the connection to the front of the PC and kept the parallel connection away from the power supply.  I ran a job today and it works.

The nice guy at UC100 support said if the driver screen works in Mach3, then it is NOT a counterfeit.

One small thing, the manual control with the keyboard is not exactly like the old PC.  Like the fine control to zero out.  It needs more technique now because it moved a lot more.  Close enough though.
