In repetier firmware the extruder motor needs to be inverted.
My Da Vinci nozzle extruded at over .05mm. The mk8 is .04mm. I'm printing at the same temperature. It seems like it heats up faster.
The insulation on the hot end block probably helps it heat faster.
Curious why you didn't just re-use the stepper that came with the printer?
I used the mk8 drive gear on the Da Vinci stepper. That way I didn't have to rewire.
I'm trying to switch extruders at the moment to a mk8 from the davinci stock. Everything makes sense except the heating wires and the thermistor wire. I'm not sure which one to use, should I use the stock thermistor and heating cables? How do I connect them and or remove them. The davinci thermistor seems like it's stuck.
I got the thermistor hooked up but I'm clueless on setting up the heating cord. You said you used quick connects? Is that like a quick way to connect wires? I.E quick connect mk8 heater wire to davinci heating wire?
Please tell me , how you level the print bed without da vinci nozzle ?
Thank you for your answer
The automatic leveling sucks, stop using it.
Manual leveling, using either a feeler gauge or a piece of paper, is the way to go.
I only manual level the bed.
Maybe the location that the extruder does the the probe could be changed. When the probe touches the metal corners it completes a circuit. It should work the same if the tip of the extruder touches the corners. The tip would have to be cleaned so no plastic interferes with the circuit.
Thanks! I will need two of these since there are two heating wires. One last question. I'm am using the davinci stock fan and I was wondering if I can use the mk8 stepper motor since the plug from the davinci stepper motor fits it.
I reused the Da Vinci stepper motor because my mk8 motor had wires coming out of it that led to a different style plug. If your mk8 motor has the same plug as the Da Vinci it should work.
Did you pull the davinci gear out or did you cut it off?
I used a crescent wrench around the shaft and hit the shaft with a punch. I was trying to save the gear but it ended up getting deformed. It would be faster to slice it with a dremel. The mk8 shaft has a flat spot for the set screw. I left the Da Vinci shaft round and tightened the set screw.
Uh, I've been reading a bit in the last few days about ways to pull the gear off the shaft (cause I just did that with mine) and some people claim that any method that involves hitting the shaft with something (hammer, punch or whatever) has the risk of messing up the stepper's internals because of the vibrations generated. So I'd be careful with that and consider the alternative ways that do not involve hitting the shaft... just my 2 cts.
