Drivers operating in erratic way

[John11668]

The first question to ask is it a genuine UC100 from CNCdrive motion controls or was it bought from eBay.?

Next, I've seen this happen many times with various controllers, and often it's a corrupted Mach3 XML. Either create a new profile using the same settings or go into the XML backup folder and use an old one that you know worked. Personally I'd set up a new one.

Or better still invest in UCCNC as it's now much better than Mach3.

The UC100 was obtained from CNC4you and I am assured that it is the genuine article .
I dont have a problem with the £60 or so for a UCCNC licence but slight concern about familiarization with a new bit of software.
Will I find it easy to convert ?
Is there a trial option?

I moved from Mach3 to UUCNC earlier this year and it is a doddle, the only thing you may need to look at are the Constant Velocity settings. UUCNC is also a lot faster when you need to restart a program part way through taking seconds to restart instead of ages like Mach3. The standard probing functions are great.

Still cant install UCCNC despite trying various settings
Will see if CNCdrive can offer a solution.
WRT The erratics I was about to change cables anyway . Will fit new screened cable and and ensure screen is well earthed and then see if any difference. Changing the controller frequency did not seem to help sadly.
Any other suggestions would still be welcomed though.
