I came across this build a few months back, and finally got started! For anyone thinking about this project, Simon was a pleasure to buy from. The plastics he sent me were perfect.

The metal base really pushed my little CNC machine to the limits, but I learned a lot about proper feeds and speeds for aluminum while I was at it. One broken bit and some ruined stock is a fair trade, I think! I've decided to ruin Simon's aesthetic by mounting my power supply on the base, as I'm less worried about portability. The additional cutouts are for a Duet 3 Mini 5+ control board, Raspberry Pi, buck converter, and USB-C breakout.




One noob question: what's the 5mm dia hole bored into the bottom side of Gantry Plate 1 for? This is my first printer and the answer isn't jumping out at me. I'm hoping I can skip it as that will be the hardest feature to machine. Cheers!

 

Thanks Simon, that's got me well on the way.

It's amazing what a mess I've made of my house creating this small machine! Axes are all moving happily and I'm waiting on a few parts to finish it off - I went a bit overkill with my heat bed wire gauge, and de-laminated one of the contacts while heating them up. Lesson learned!

I was pleasantly surprised by just how rigid your design is, I thought there would be more compromise with the cantilevered X-axis than I'm seeing. I'll post some pics once a bit more progress is made.

 

Parts finally arrived - I've got a silicone heater on the bed, which works well. I like your dual hot end setup, but keeping it simple for now until I figure out how to use one. I had some trouble with the extruders grinding until I added some blue loc-tite to the nuts holding the tension bolts and the big external gear, which was unwinding during use of the right side extruder. They were easy to open up and clean out - great design. I need to buy some tiny nylock nuts.

I'ts been a few days of dialing in settings, but I'm incredibly happy with the end result. With pressure advance enabled, I've got the speeds very slow otherwise my infill suffers - I'm not sure if my speeds are normal, or if the machine can handle more with better tuning. Max 30mm/s, 15mm/s on the delicate stuff, and 200mm/s travel with PETG and a 0.4mm nozzle. Some persistent blobs I can't seem to get rid of, but nothing that won't buff out.

This thing's hypnotic to watch - this is a fantastic machine, Simon. Thank you.

 

After looking at several 3D printer projects recently, I've came to realize how well documented this project is, when compared to others.
It's really nice to have drawings of everything.
So congratulations to mr. Indieflow for that. And thanks.
