Hello everybody, this is my first post in this forum!
I have purchased a 1212CNC router from China which I plan to manufacture my parts with. I have run into some problems which I can't seem to get my head around and request some help!
Ok, so my first problem has me thinking that there is a bent ball screw on the X-Axis. No matter what feed & speed combo I throw at it, there are marks on the surface (even when facing 0.1mm deep) at 10mm intervals. My ball screw is a 2510 which leads me to believe that a bent screw could be the culprit. I have tried adding a flexible jaw coupling, re-aligning the screw, and shimming the ball nut to no avail...
My second, larger problem, is that when climb cutting on the Y-axis (Y+) the spindle seems to 'Jump' through the cut, visibly shaking. I am aware that routers lack rigidity however this is a machine which should be more than capable of machining 6061 aluminum at the feeds I'm giving it:
RPM: 10,000
Feedrate: 1000mm/min
DOC: 4mm
Optimal Load: 1
This combination seems to be working well for very similar machines online however my machine prefers shaking itself to pieces!
Please let me know what you think, I'm at a point where I feel as though I've checked everything and just trying to find the cheapest upgrades necessary to make the machine perform better
