What voltage should the stepper drivers be set to? The build guide for the old model mentioned this, and I don't see a corresponding entry in the new guide. (Not that I have my kit yet. It shipped today, so I'm living vicariously by reading the manuals and forum posts.)by animoose - Prusa i3 and variants
Looks good. I have a spare fan somewhere. Looks like you have the mounts are something I could print ... hmmm ... if only my printer was finished.by animoose - RAMPS Electronics
Thanks for the advice, everyone. Is the heatbed MOSFET is Q3 in this diagram (http://www.reprap.org/wiki/File:Arduinomega1-4connectors.png)? If so, it looks like there is plenty of clearance around it so I can attach a heatsink. The one I had in mind is a small (15mmx15mm) one from MCM (http://www.mcmelectronics.com/product/83-13677?utm_source=transactionalemail&utm_medium=email&utm_campaby animoose - RAMPS Electronics
Should I add heatsinks to the FETs on a RAMPS 1.4 board? I've read various reports of them overheating, and I've got a few spare small heatsinks and some thermal paste lying around. Is it worth doing this as an extra safety measure?by animoose - RAMPS Electronics
Looking forward to hearing your experiences. I ordered one yesterday, no ETA for delivery yet.by animoose - Reprappers
If I have a printer that takes 3mm filament, is it simple to convert it to one that takes 1.75mm by just replacing the J head? The reason I ask is that Replikeo advertise a kit at $250 with 3mm and at $350 with 1.75mm, but on ebay you can see 1.75mm J heads for $10 or less (example: ). I appreciate that the really cheap extruders will be low quality, but this seems like a big price difference betby animoose - Reprappers
This kit looks interesting. I've been on the fence about which of the many kits to buy and have more or less settled on a Folger after reading the other long thread on these forums about it. I am not keen on acrylic frames, as an aluminium one looks good. Replikeo is about the only other one I've seen with a steel or Al frame at a price I can afford. From the picture at it looks like the Z axisby animoose - Reprappers
