Building out the MPCNC. Starting printing from a humble Anet A8 modified with an SKR V1.3 and TMC2130’s. Using a brand of filament called Duramic, which prints like crap but the parts felt sturdy so I just rolled along. Took about two spools but there were calibration prints and other prints in between. I measured the time each part took and weighed each of the parts after printing to compare to the listed projected weights in the parts section, most of the weights were within a margin of error but others were way off, which concerns me a bit but not enough to not put the machine together.
Projected total filament used: 1793.28 grams
Actual filament used: 1589.6 grams
where most of the difference was made up by just a few parts but mostly the XY_C_Burly with a projected weight of 201 grams and an actual weight of 139 grams , oh well.
Printing times were mostly accurate, there were some time savings since I was printing at .32mm layer heights but nothing to write home about since the print head was moving at 40mm/s
Waiting until this weekend to go do curbside pickup of the conduit and table materials with the control board, 660 and other parts being delivered later.
Picked up the archim 1.0 since it was available on this site. I’m familiar with creating custom marlin builds with platform dot io (can’t include links) from getting that working on the SKR, so it shouldn’t be a bad choice.
Does anyone here have any recommendations on how guides on how to build an enclosure of the printer table? I want to eventually cut aluminum and also have heard that wood dust is pretty gnarly stuff (cancer…) so I wanted to build something that was as clean and safe as possible, help here would be awesome. If it helps, the machine will be placed right under a window in my garage so access to easy ventilation is possible.
The plan is to have something that I guess is considered large, with a conduit X and Y length of 43" and 33" , which may hinder the aluminum dream but we’ll see.
Will hopefully have a mostly built out pic of the CNC by this Sunday. Looking forward to feedback.
