QuotePointy Well that was a bit of a failure. First off the brackets are no good, there isn't enough room to get the USB cable in, so I am currently printing mark 2. Next up, all of my end switches were broken, so I had to replace them. I was trying to keep things neat with heatshrink, but the heatshrink obviously didn't want to bend when I put the caps on and damaged the switches instead. (Reaby dougal1957 - Delta Machines

Quotetjb1 Quotetanner331 I use both ABS and PLA This problem occurs more with PLA but it also occurs with the ABS. I'd say your main problem is the E3D, it's terrible with PLA and likely jamming and causing the extruder to strip the filament. Sorry but I would have to disagree re the E3D being bad with PLA as long as it is an original one that is (The clones may be a different thing) I have hadby dougal1957 - Reprappers

How much current/torque do I really need for a printer? The motors I found run at 4.4V and have per phase current draw of 2A resulting In holding power of 63 oz.

I couldn't get marlin to even compile for me hence I went to Repetier which to be honest I prefer anyway now though next printer will be a 32 bit controller as it will be a semi large delta (400mm dia bed with 1000mm towers) should give me about 550 mm build height at 350mm diameter or so just need to print all the parts for it now.

Quotedc42 To use a thermocouple, you need to use a thermocouple amplifier chip. Like all the other printer electronics I am aware of, the Duet does not have one on board. The easiest solution (other than using a thermistor instead) would be to use one of the available thermocouple amplifier breakout boards. These come in two varieties: digital output (typically based on the MAX31855 chip, e.g. frby dougal1957 - Delta Machines
