It’s been a bit over a year since I had to disassemble my old 525 because it wouldn’t have fit in the new apartment. Ever since then I was thinking about how to bring it back to fit in the space availlable to me now…
For the last couple of months I have been measuring spaces, moving things around and even gone so far as to sell a machine that I haven’t been using much anymore, an old chopsaw!
Well I found a small space under my workbench where the new MPCNC can stay. It can only have a 300mm*220mm workspace, but that fits my other plans for this build just perfectly
Small and rigid!
2 days ago I started printing parts, so far all of them from Fiberlogy Carbon Fiber PETG.
As you can see in the image below, the first print on the left had some major overextrusion issues, but after a couple of iterations all the settings are dialed in quite well
I have about 600g of Prusament PCCF left over from another project and was thinking about printing the core from that. That would leave me with ~100g left on the spool, what other parts would you recommend to be printed out of PCCF?
I was thinking the Z axis parts?
Ryan is going to have the best info on what parts get the most stress. Personally, I’d do the tool mount in PCCF. I’ve broken my mount a couple of times, and ended up beefing it up somewhat.
So far I printed all the parts with 2.1mm thick walls, that should help with rigidity. If it turns out that some parts are still not stiff enough I can reprint them from CF HTPLA or PCCF…
It will help a little, at least it will stop the table amplifying sound, it won’t do anything for the airborne variety. Think of a guitar or violin body, the sound boxes are actually tuned to amplify the sound in a specific way. Our tables are like cheap ukuleles!
I thought about randomly spacing the webs in my last table to give a variety of pitches of resonance for each square, in the hope that they would magically cancel each other out, but then I looked at the maths involved and thought… nope!
