Question Help with Plunge Rate/Z Axis Speeds for 3D Milling

Hi,

i have the same issue with SC2 black edition. I use UC100 and UCCNC with Win10 Vectric Aspire. I only lose Z-steps. Before i lost Y steps aswell, but that was manufacturing issue and leadscrews where binding. I had to add extra washers to one side rollers, so x-axis carriage did not bind Y-axis. Allso i added ballscrew nuts to get friction down. I discovered now that stepperdrivers where overheating, so i i added some cooling to it. But i still get problems with z-axis. And there is noise aswell

Anybody have some new info? I use UC400ETH with UCCNC with my DIY CNC with no noise and issues. Seems like there are so many issues with this machine

Best wishes!
Martin
