Hello. I've been having a bit of trouble with the vibration on my Workbee CNC machine rattling loose screws and whatnot. It seems to just slowly take itself apart. I've also been finding the stepping motors spinning free when the screws holding them to the lead screws loosen. I'm tempted to just threadlock everything but I'll certainly regret it the minute I need to change anything! Any tips? The other day it was cutting something out and this long grub screw fell out and I can't find where it goes. Can anyone on here help me work it out? I'm hoping it's not important... Thanks in advance!
