Re: New Own Design Printer 'Cherry Pi'
Vreihen, that effector/mount looks good. I would have to redesign it a little for my 43mm rod spacing and magnetic attachment but if I ever feel he need to a) auto bed level and b) regain my full...

QuoteTheTechnicalNoob So you managed to store the bed leveling data in the eeprom which eliminated the need for recalibration at every print? I was trying to find a way to do this but failed to find...
View ArticleRe: motors getting really hot!!
What does it mean really hot? How long is your stepper without shaft? I push about 1.3A to the extruder stepper and it is not getting hot. It is only about 45°C. Its phase resistance is 2Ω. That means...

I cant see it working. Whilst it's a nice idea, makerslide, openbeam, vslot, et all are pretty much a complete failure due to price and lack of demand. The thing is this: We have printers. So why is...

Regarding the rods - 6mm metal tubing works. Andy used it on the Cherry Pi. It's dirt cheap too. In the UK it's sold in B&Q. A load of online places sell it as well so if you're elsewhere it...
