Hey, new to this forum and would appreciate some help...
I bought a used CNC, Platform CNC by Grunblau about a month ago. The anti-backlash nut's collar was unscrewed on one side when I bought it so I figured out how to tighten it back on. CNC was working great with mach4, made several cuts with it over the past few weeks.
This evening the Y-Axis started cutting out of sync with MACH4 during a cut so I stopped it. Then I tried to jog it and nothing happened. I lifted up the spoil board to find both anti-backlash nuts slipped and I have no clue why this happened or how to fix it.
I hand threaded them a little and the machine jogs fine. There hasn't been any binding or weird noises/shakes prior to this.....It was working great and then it wasn't?
How can I fix this so it doesn't happen again?
I'm attaching pictures and any help would be greatly appreciated. I'm really new to CNC and want to get back at it!!
