UCCNC has been a deeply unreliable and unpredictable mistress in the 2.5 years I've been using it. Random movements have cost me hundreds of hours and dollars in damage and have very nearly cost me limb or worse. Random freezes and crashes are increasingly common as updates roll out. The motion controller consistently disconnects from the PC if left on for any sort of extended period with no changes in voltage. Thousands of lines of my profile randomly deleted. All of which and more I have literally begged and pleaded for 2 years for on the UCCNC forums but am consistently told that it's my equipment, which after EXHAUSTIVE troubleshooting it is proven untrue. And then the knee-jerk is that I'm the 'only one this is happening to' when that is demonstrably untrue. Most recently, after describing an issue I'm experiencing with the UCR201 pendant for the umpteenth time, I was told by Balazs that I was the only one experiencing issues, after which 2 others chimed in stating that they were experiencing the same issue, and Balazs has promptly stopped responding to the thread, or any other thread I'm participating in. I'm not unreasonable, but I am more persistent than those that have come before that gave up which seems to be the response for the very real but slightly less common issues with UCCNC.

If I could, I would love to dump this software today and get into something else. However, UCCNC happens to be pretty unique in this space that is occupied by much worse monsters like Mach or less flexible solutions, my workflow is now married to it, and the issues are just inconsistent enough that I can convince myself it's not worth gutting my machine to switch to something else. I run a business and *can* tinker, but am not in machining to tinker. I'm in machining to produce work reliably, but UCCNC seems to really just not be that software.

This might be more of a rant than anything else. If any old timers have some wisdom that isn't "It's just you" I'm here for it. Really not sure what to do except bin this motion control system.

Hi - What motion controller do you use? I use UCCNC and UC100 and its been pretty good for 5 years. There is a glitch in the CAM side of it if your using that at arc starts it backtracks occasionally. But now I use Fusion360 and import gcode, it has been rock solid on stuff I do. Peter

Hey Pete, I'm on the UC300ETH.

sorry no experience with the UC300 - Peter

Hi,
I have used Mach4 daily for eight years without the sort of hiccups you are referring to.

A month or two back I found my machine when doing rapid traverses was having an occasional glitch and had been getting worse. It would not lose steps but rather move in a discontinuous path but
still end up at the right location? That's when I recognized that the little PC (Dual core Atom, on chip Graphics, 3MB RAM) has been running continuously for four months. I did a power cycle and the problem
went away. I make it a habit now to turn the PC off once a month or so. Other than that my PC runs for months at a time without ever losing Reference let alone setup or profile data.

My understanding is that UCCNC and Mach4 are similar in terms of look and function. I think Mach4 has an advantage in screen editing and scripting environments which makes it very flexible.
From your description I would guess Mach4 has the better record for stability also.

I have the same problem with UCR201

There should be a fix for it, but I have not tried. Check this: https://forum.cncdrive.com/viewtopic...=3598&start=10
