Just got the machine going yesterday, today I was running higher feed rates for Z, then it just stopped, and now I hear an random grinding noise.
Took Z screw off the machine, looks like there is some grease from the bearing on the top of screw (see pic), and when I rotate it by hand it will bind and make grinding noises.
Any ideas where to get replacement, and how to install new ones, also what size spanner tool I need to pick up to take the nut off?
Thanks!
UPDATE: CNC Fusion is sending me new bearings, and gave me tips on what spanners on mcmaster might work for the z nut. I would give them an A for quick email response.
Also picked up local bearing replacements in town, here is the make\model that matches Koyo 60002rsc3 gxm 00711, cost was $10 for two.
