Fixing up a used M2

[insta]

I've actually been experimenting with no fans on the RAMBO or filament drive. This leaves only the part cooling fan and the power supply fan for noise, because the motors are so goddamned quiet with the dampers.

Until I installed the auto-levelling stuff that is, now it's constantly squealing with microsteps.

I ditched the filament drive one along time ago (I didn't mind being the guinea pig on that one) but I was too scared to lose the the case one as I'm not sure how hot the boards get. The 24 volt fan I use now in the case is probably louder than the stock two. Let us know if there are any long time effects of not running the case one.

I did just start experimenting with the blower type fans for cooling and it's pretty quite, I though about sticking one of those in the case too.

I think it's 2-in-1 for the round rods on the Z-Axis and greasing the X and Y linear rails and Z threaded rod with white lithium?

Curiosity got the best of me.... I just looked this up in the manual and it says "Clean oil from the X and Y linear rails and apply a fresh coat to each. A dot of oil in each of the long grooves on the X and Y rails is sufficient. Once applied, move that axis through its full travel multiple times to spread the oil.

Thanks for checking about the oil. The white lithium seems to gunk up a bit.

I did a longer print today and the M2 is working great.

That's not what it used to say (about the oil). Wonder when that changed. It even came with a tiny tub of grease.

I thought I had read about the white lithium somewhere so I found the docs that came with my first M2 printer and there is a section about lubrication. That was about 3 years ago.

Best pictures of a V4 mount . They are so much better then the ones on the MG PDFs. I am almost ready to do the upgrade. I have the parts. The V3 is working fine for me but I want to try PET.
