I had a mk3 kit ordered back in March but got frustrated with the delays and cancelled that and now I have two monoprice printers. One select plus and one mini! I have really been using both and I love to see a fusion 360 design come to life on the printer! Jim
Then the X-Axis along with the Z-axis lift motors and screws:
The extruder built and attached to the X-Axis. This took the bulk of the build time tonight, as there a lot of parts to put together, and cables to route.
Cable management on the rear of the extruder.
So far, the build has been a breeze, apart from some fiddly bits where M3 nuts have to be pressed into some deep holes. And the instruction book is amazing, you get a full colour printed book, and it’s in English, not some facsimile of the language.
These are some fasteners I designed for my friend, who in his spare time is the boatman at the local rowing club. He wanted some nuts making up to hold things in the racing boats (I forget what it’s for, but these are the same sort of 4 or 8 man boats you see at the Olympics and the Oxford V Cambridge race on the Thames). The crews have a tendency to do things up too tight, stripping fittings out the fragile boat shells and causing lots of grief and costs to the club. These are can only be done up by hand, and if they try and wail on them the nut will strip out of the plastic before it does any damage to the boat.
I’ve had the fusion 360 files sat on my laptop for ages, as I couldn’t get them to reliably print on my old delta printer. The MK3 romped through them.
They’re M6 nuts pressed into the bottom, and the text reads “HAND TIGHT ONLY”, just so the crews don’t forget.
Great work with your MK3. I ordered a kit that arrived in late January, but due to major, unexpected changes to my schedule I didn't get the build completed until this week. Was happy to see that, after a couple of relatively minor tweaks (tightening a belt, adjusting height of the sensor on the extruder) I'm getting clean prints. Now my only issue is that I've managed to forget everything I learned about Fusion 360 over the past few months. So some major resharpening is in order there.
For the printer enclosure you built--is that functional or aesthetic? I was just wondering about it the heat generation in the box if that would make taller parts sag, or if by maintaining the build area a little warmer you would get more even/slow cooling and hardening of the part? Looks good though, answers the question of where to store the darn things when you aren't using them. That second print of the boat came out great! I can barely see any layers.
It’s functional... certain plastics really don’t do well with drafts and stuff causing diffent cooling rates of the part. This causes warping and possible printer crashes as the head hits a corner or other feature that has lifted.
I need to modify it though, as the MMU unit needs a little more headroom inside for it to fit nicely and for access to it.
