RE: Y-Axis improvements (collecting thread)
A Youtube channel called Robothut does mods to the Prusa that look really interesting. Here's his linear rail mod: ,
He also has another one using 'Ultimaker-like' brass-graphite bushings that reduce noise ( ). I ordered some, but it'll take a while to get here from China. My current MK3S works fine, but it's loud during fast infills so I had to turn it to stealth mode so I could sleep.

I have various JST type connectors with 2,3 and 6 ways for the Stepper, pinda, fans etc. I also bought a few XC60 connectors to use for the heater. I've read that the xc60 can be hard to undo once connected so if I find its troublesome I'll replace it with a tamiya connector used on RC model battery packs. I have a few of those laying around and they should take the current requirements of the heater.
I'm planning on having them behind the x axis, i'll wrap from the control board to the connectors and then again from the extruder back. That way I only have to worry about the extruder to connector area when making changes. We'll see how it goes when I do it 🙂

@neophyl
thank you,
XC 30 would be more than adequate on the heater, Tamiya connectors are huge!!!
on the mk3, the 40watt heater draws less than 2 amps
on the mk2 printer the 40 watt heater draws less than 4 amps

Yeah I know but I like to over spec when it comes to electronics lol. On the tamiya I have both the normal size and the mini type. Comes from having a misspent youth playing airsoft and having lots of various battery packs around. I also design and build embedded electronics so my parts collection often has stuff I can use in it.
I really shouldn't have watched those youtube vids, as now I want linear rails too lol. I think I'll rebuild with the printed ones Chocki posted and look into getting some linear later.

Hi,
I made a polymer bushing and a bushing clamp for the Y-axis a while ago.
