Hey All, Just a quick I3 MK3 update. After over Four (4) miles of filament, my X Axis linear bearings are asking to be retired..
The two 8mm S/S carrier rods show no degradation in diameter which is great news.
What prompted the maintenance check was a dramatic increase in 'crashes' while printing, so me being me started looking for software and firmware issues and not a hardware issue.
In the last firmware update, Prusa had adjusted that sensitivity while adding some detail enhancing algorithms to the updated Prusa slicer.
All-in-all, great fixes, but it did increase the likelihood that crashes would appear at a higher rate. (You can override this by switching to "Stealth Mode", but print times will be a bit slower).
Turns out the linear bearings are worn to point of replacement and while I am replacing those I will install the Mk3 "S" Upgrade (I bought in 2018 LOL).
The Axiom being, if your printer is printing to your satisfaction don't make changes for the sake of change. Good Advice, that.
It seems a small thing can effect the larger over time and much like the frog in the pot of slow boiling water, I didn't notice the problems until it was too late.
This sort of maintenance is easy and inexpensive, 3-4 hours of disassembly-reassembly and less than $50.00 in bearings with shipping.
So, after a few miles of filament, if you're having frequent print crashing or even unexpected artifact issues, first lube your linear bearings and next try replacing those.
Best to all, LB
