Re: Kossel rails vs wheels
I'm glad someone asked this as I was going to myself :) Here's what I can tell so far. There are three common variants. 1) Use smooth rods either side of a makerbeam/open beam/standard t slot/square...

Thanks for the input, your Cherry Pi looks like a really nice build! I was indeed thinking about option 3 and have also found a similar discussion regarding Graber wheels vs MGN12 rails on the google...

It's not my build - it's someone elses. I'm just using it as a basis on planning my own build as I loved the idea of using the rails as both support, and for movement, and probably even for getting 5v...

Have you got fans and heat sinks on your stepper drives? My first guess would be your stepper drives are overheating and dropping steps. Try dropping the motor current if you can't add fans and heat...

Quotemikep-nz The problem with using Aluminium tube as a bearing surface is that the soft aluminium surface is so easily damaged by dust and dirt and once it gets damaged it quickly deteriorates to...

Mikep-nz would you care to post a picture of your aluminium extrusions that were ruined by the bearings?

I know size wise this is probably useless, but how about something like this to wrap around the outside of the bearing: [www.ebay.com] It's basically just a rubber casing, presumably to fit right on...

I stumbled upon something potentially useful for the future. Basically I was looking at types of aluminium extrusion, wondering if you could do some sort of wheel based rail, without needing to attach...

Not related, idea: You could use two of the rubber bearing covers with a Dia 22 mm, 608 bearing to create a self aligning system, and/or absorb vibration. (tu) A means to hold the bearing within the...

Hi guys. The bearing on extrusion noise is actually fairly minimal. I've put about 1.5 kgs of filament through the printer and there is no sign of wear. The majority of the noise is from the belts,...
