I've pretty much gotten the message that Robo will not have any spare parts for the R2 any time soon. So, if i was to look for the thermistor plug that they use in the hot-end, what would I look for? Is there a specific type name I can look up to find them on Ebay or Amazon? What is the procedure for crimping them onto the plugs that the extruder uses? Right now I'm waiting for a replacement from Robo, but I wouldn't mind having a few spares around, just in case. I can find the 24v heaters without a problem, I just can't seem to find the connectors that are used to plug it into the extruder. Are they mini-molex connectors? Funny how I've been building PCs for years but never knew the names of those little three/four pin connectors. Maybe we should start a little unofficial parts list and where we can find them?
