Having had in mind to enforce my version 01 MPCNC for a long time, I finally managed to cut four motormount plates from 6mm aluminium. Mind you, cutting was done on the MPCNC itself.

A hint that we can expect an MPIM?
(Mostly Printed Injection Molder)
I felt very much in the tradition of the original RPers when making these: The self-replicating and -evolving machine.
One could cut them from hard plywood (at least birch, better beech or mahogany) too.

Failed attempt of the machine to replicate itself. 😉March 28, 2019 at 5:54 am #94827
I just finished replacing my original version 1 machine with the latest burly parts. I have to say that it is functionally and practically a totally different machine in terms of performance. Although I use mine almost exclusively for carving, the difference in rigidity and reliability are astounding.
I’m impressed that you were able to do those aluminum parts with that version of the machine. I never even considered it an option with my own. What was your tool and feeds/speeds?April 3, 2019 at 8:01 am #95440
Sorry it took me a few days to reply; I used 2flute-VHM aluminium end mills bought from Sorotec .
They also have excellent drill-less tools for wood. Makita RT0700 spindle, running at about 14kRPM, 0.1 mm per Z-step, 200mm/min, and widening of the slot to an island, 30% track overlap. Don’t even think of making it faster. And that with the old sloggy setup.
Right now I am printing the Burly parts, giving my new 160 € (!!!) alfawise U30 printer a nice burn-in. Nice machine for that price! As with the first generation, I use PETG filament.
Oh well, and thanks for your comment!April 3, 2019 at 8:52 am #95443
Ulli, what cable did you use for your steppers? Looks like a nice shielded cable.April 27, 2019 at 12:18 pm #98303
Hi, sorry for the late reply. Yes, industrial grade multipole shielded cable. I don’t like the thin model train wires. Way too much inductivity. I think these are 4 x 1.5 mm^2, don’t know the corresponding AWG#.
