Hopefully someone can offer some assistance, video attached describing and showing the issue.
X-Axis motor goes into a high pitch squeel after stopping motion (not normal motor whine) & loses steps
when swapping the cables on the x and y motors, the x motor moves and sounds clean, while the y motors show the issues above.
Using the Mrambo that came with the kit, pwm_motor_control is unaltered.
Hopefully that provides enough info for someone to help.
Thanks!August 4, 2019 at 11:51 pm #108446
Is there an easy way to change in Marlin the motor pinouts, to effectively swap x with e? Using the extruder motor output it runs great. Just the x motor output seems wonky. I’m using the firmware linked off the main page, and the mrambo board was the one provided in the kit.August 5, 2019 at 6:06 am #108471
I wouldn’t worry about it. They all do that to a point. When my printer does it, I just jog it a couple mm, and it stops. I think it does that when it’s between real steps, the microsteps keep it between full steps and it vibrates in that spot.August 5, 2019 at 6:06 am #108472
You can swap the pinouts in pins_minirambo.h
Does it act any differently or just whine?August 5, 2019 at 9:56 am #108501
The motor vibrated excessively, caused the set screws to come loose, I secured them with some medium strength loctite.
I swapped the motor pins in marlin, and I’m using the E motor driver, everything works better now. guess I just got a partially bad board.
