Ok So I'm building a #Prusa Mk4 3d printer. The gummy bears were a nice touch but the whole kit is amazing. The instructions are top notch too. Maybe I haven't done this a lot (I haven't) but docs like these take an incredible amount of work. Hats off to them.
"Step 10 Y-axis: geometry check" showed me just how warped both my desktops are. On an actual flat surface it doesn't rock at all, on my desk.. well I was very worried I had somehow warped this steal and aluminum frame with an allen wrench.
The xBuddy itself is a sizable controller computer. Ethernet, 2... maybe 4 motor controller, heat bed controller, something called "power panic" (which I really want to know more about) and an lcd controller.
Oh that's cool - power panic is litterally the system detecting a power loss, keeping enough power in it's caps to move the print head to a safe spot and writing the current progress to memory. If power restores fast enough it will just start printing once it's powered back on.
Even cooler prusa has a page full of videos about how to test each safety feature. This isn't something I've ever seen before in any equipment I've ever been around.
Whelp I got the y axis motor installed (they have you insert nuts into 3d printed parts and that's a neat trick) and I'm done! Only 6 more sections to go...
The X and y axis were fun to build. The X also carries the extruder. I’m enjoying the elegance of sticking hardware into 3D printed parts. The threaded black caps that travel on the y axis threaded rods is super cool too. I was like how on earth will I align this? The caps can screw in quarter turns!
It’s been a wild week and I was able to steal a minutes here and there and didn’t take enough photos for a narrative. But I like what I got to share so I’ll share it. ¯_(ツ)_/¯
I got the heating unit and electronics (loveboard?) attached. The amount of work that goes into this extruder is awesome. I would not have thought so much could go into such a small device.
