Drivers operating in erratic way

Try installing it as Administrator. "Jit" stands for Just in time debugging.

I am the Administrator Jaz.
It is the only account on this machine .
Tried uninstalling and reinstalling all to no avail. Tried with and without UC100 but throws up the error .
Yet Happily installs on an XP pro or a Win 10 machine neither with UC100.

Process of editing the registry sounds dangerous to me

...often as part of a Java installation. Try installing/updating from Oracle.

Much as I appreciate your advice doddy , you could be talking chinese as far as I am concerned .
Can you expand a little on the process (preferably in words of one syllable) for those who( like me) are IT challenged

Apologies.

I'm largely guessing here but, whilst Jazz is correct that JIT is an acronym of Just-In-Time, this technology is frequently and commonly associated with the Java JIT compiler. Java, being a programming language and development environment common for cross-platform development.

Because you mentioned you was getting run-time exceptions that referenced the JIT debugger, it's one possibility - and just that - of an issue wrt to the installed version of Java on your Win10 machine. Just a possibility, not a hard diagnostic.To this end if you go to Oracle's site (Oracle bought out Sun Microsystems, who developed Oracle), then you can download the latest and greatest version of Java. See here

This is just an idea - for the reason given above, and that I, and you also, have already got UCCNC working on other machines without problem.

I'd also suggest giving the full details on the UCCNC forums - they are active.

That's the forth person I've seen that's been having problems and been using a UC100.
That thing really seems like fitting a band aid that was quickly bought out when PC's started removing the parallel port.
Connector converters have never been very reliable.

Dump the junk and get a UC300 or 400ETH, a couple of cables and bob's. Save yourself hassle.

This is the way I'd go in the future when I eventually need more pins. UCCNC / Servo spindle / Toolchange etc.
As it is my £40 Dell refurb (with actual p,port), WinXP, £7 bob & Mach3 have been faultless for over 3 years on 3 axis.

[Doddy]

The UC100 is not a connector converter, it is a motion controller, similar to the UC300/400 that you recommend.

I understand too that it is needed to make Mach3 work on a 64 bit processor. Mach 3 was ok on 32 bit machines but 64 bit machines needed them.
Or is someone going to tell me different?
This machine actually does have a parallel port if anyone can tell me how to make it work

I always thought that the 64bit processor count doesn't matter as it is backward compatible to 32bit. So a 32 bit OS can be installed with no issues. The difference is the ram usage allowance.

Being honest Daz I dont really understand the ins and outs.
I was advised by a chap I met at the Alexander palace model show( member of the society of experimental engineers and I understand he was their CNC guru) that in order to run Mach 3 on a 64 bit machine I needed a UC100 . It would not drive even a single stepper when I first tried .
I took his advice and it then worked.
Same gentleman guided me here so his advice seems sound enough.
He may well be reading this thread !

Hi John
Just a thought , have you tried registering from a smart phone ? Or set up a gmail account.

Cheers
