Re: Molex connectors - Help!
I don't think that it is a Molex-brand connector, but rather a 0.1" spacing pin header plug. The Molex 2510 has the same pin spacing, and is the common keyed Molex connector used on stepper motors:...

I'd strongly recommend to use connectors with a latch to protect against insertion the wrong way. Molex KK100 is the de-facto standard, many others are compatible.

Powers of two problems with stepper motors are usually related to micro-step settings in firmware or jumpers missing from your board. You didn't provide an exact measurement to work from, so I can't...

Hello, All the jumpers are on the board. I tried to run the Z-stepper motors without the jumpers and they are turning more quickly, but with a lot of noise compared to the X and Y axis. Is there in...

It could be some sort of "prevent dangerous extrude" where it checks for a certain temperature before letting the extruder motor move. Because if you try extrude with no heat, you could damage the...

Thank you for your answer! When I was searching on different forums, I read that. So I decided to try it. I hooked up the resistor and the thermistor. I heated it up to 175°C, but there was no change....

I prefer the Molex SL series - this has wire-to-wire housings (as well as male and female pins) that the KK is missing, and also has a SL-wire-to-KK-board keyed compatible connector as well as plain...
