The cycle is complete! Borrowed a friend’s anet a8, built an MPCNC, used MPCNC to cut the MP3DP. Now I can return the printer!
Pretty standard stuff across to board. 0.5" plywood frame, 0.5" MDF base, mini rambo, titan aero, and other misc parts from Ryan’s store. It was a great exercise in getting speeds dialed in for various materials. The only thing that’s different about this build is that I milled the y speed plate out 0.125 inch aluminum. The 1/8" aluminum y speed plate weighs approximately ~120g which is about twice as heavy as the same part cut out of 0.25" MDF (62g). For reference, the full y plate cut from 0.25" MDF would weigh in at roughly 220g.
The very first print came on near spot on with ~0.1mm error on a 20mm test cube. This has been a breeze compared to modifying and tweaking the A8 to produce decent prints.
For anyone else using the Titan Aero - did you have to cut or purchase a spacer such that the pinion for the gear drive on the extruder could be spaced properly? I ended up printing a 2mm spacer with PLA but wonder if it won’t warp over time given that it’s smack dab up against the heat sink.
Obligatory… Don’t mind the missing stack. It was broken off on purpose
