Hi,
I'm almost ready to make my first cuts with my X3, thought I would ask a few more questions first.
Backlash. I bought kit #4 from CNCfusion. I have heard others mention as well- that the locknuts for the ballscrews are incredibly tight. I tried to set mine about where I thought they should be to preload the bearings enough without being too tight and causing wear/damage. While setting up the motors in the Mach3 software, I noticed .010-.025 of backlash on my dial indicator.
I have read the ballscrews can have .003 or so of backlash, so I assume the rest is likely slop in the bearings- possibly loose mounts?
Where in Mach3 can backlash be accounted for if I still have "too much" after adjusting mounts/bearing preload?
Any tips for fine tuning/ first test run help would be appreciated.
