I am about two weeks into by MPCNC build, and I am somewhat obsessed. Between family and work I have been struggling to find time to learn and design my build, but it is coming along. I have been reading as much as I can in these forums and have been resisting to go overboard. I would like to build a solid machine with as much accuracy as possible and have opted to upgrade to 1” stainless steel tubing. I purchased a 20’ length of stainless tubing which has blown my budget for upgrades or any additional tubing right now. This is limiting my usable dimensions to 22x22x5, but I am hoping it will give me good tolerances and I figure I can always upgrade in the future if I want a larger build area.
I am about to purchase some parts from amazon and I am a little apprehensive when looking for acceptable bearings. I feel pricing and quality are all over the place. I purchased some bearings a few months back to make a fidget spinner for my son and was disappointed with the quality and how poorly they spun. How concerned should I be with bearing quality? Will this have a big impact on machine performance?
The printing is coming along, with almost half the parts printed. I had an odd failure printing the Roller pieces last night where after a few layers in it appears the printer went haywire … I assume(hope) it was some glitch in the gcode. I resliced the part and kicked of the printing. I am new to 3d printing so I am unaware if this is common or a sign of other issues. So far so good with the new print.
Here is the accent color along with the standard black, it was this or the grey that came with my PRUSA.
