Solved Nitehawk-sd Extruder Motor Not Working

[EdB]

I couldn't find any specific for for the Nitehawk so since I found other questions about it here, I thought I would try this forum first.

I upgraded the Stealthburner on my Voron 2.4 r2 printer to the Nitehawk-sd board. I have gotten all the functions on the board to work, except the motor. I have two printers I was going to upgrade so had another Nitehawk that I was able to try. Same problem. Everything worked, except the motor.

I used the LDO doctumentation on for the Nitehawk for the configuration. Has anyone else experienced this problem?

Here is the part for the exteruder. I only commented out the lines when the extruder was connected directly to the Octopus board.

## Update Gear Ratio depending on your Extruder Type

gpio's all looks correct, try bumping your run current to .6 or .7

 

[EdB]

I bumped the current up to 0.7 and still no luck. After I send an extrude command, there is no resistance to turning the motor by hand. With other printers, I would feel some resistance even if the current was too low.

I thought maybe the wiring was different, but even when it is, I would hear something when trying to move the motor. I don't hear anything at all here.

Tried a different motor with no luck.

Moved the motor back to the Octopus and tried it the way it was. That worked. So I know the motor is good. The one thing different between the Octopus and Nitehawk is the use of a TX_PIN. Didn't have to use that with the Octopus.

Okay. I'm an idiot. I missed the ! in front of the enable pin. It's working now.
