Anyone know why I would get this?
Pot set too high perhaps, PID’s not tuned properly, Belt tension way too tight… there could be several reasons
Please Check the wires to E Motors…i Sounds like wrong conections
Probably, the sound is coming from extruder
Someone mentioned end sensor not hitting. Going to check that first.
Sounds like the stepper is missing steps. This is likely because your driver voltage is set too low - thereby lacking in torque to actually move things. Best way to be sure is to simply measure the driver’s voltage.
Loose belt or dirty/bad encoder. Shudder down, check wires let it re-home.
What command did you give the printer that resulted in that sound?
I was just trying to jog the axis
So that would be coming from your X axis motor since I take it that is the one you are showing not moving. If it was all the way over to home and doing that I would suspect your limit switch not tripping.
Low power was already mentioned. Bad connections, a broken lead, or crossed leads can result in that sound as well. An intermittent connection will often result in it bouncing back and forth which can be confirmed with a cable wiggle.
Do any of the axis jog properly? If so swap the leads between a working one and this motor and see if the issue follows the motor or stays with the board connection.
@Greg_Copeland Do I need to install jumpers to the drivers? I had some pololou drivers initially, (did the same thing) now drv8825. 12v, 480watt PSU on an MKS GEN v1.4 board.
@Jeff_Parish thank you. That sounds wise. And yes, the y-axis runs okay.
The problem seems to be with the board because my working y-axis Motor doesn’t work when plugged into x-axis driver
And x-axis moves perfectly from the y-axis driver
Ok. That narrows it down. Next step would be to compare the voltages you get across a working driver as compared to your X. Then if your drivers can be swapped out try that to narrow it down further.
@Jeff_Parish Thanks Jeff. You are quite helpful. It may take a minute, if I dont get back right away
how do i test the voltage across a driver? where do i put the multimeter leads?
Not sure for your drivers. Can you show a picture of them or find a pin-out description?
I’d try swapping out the driver on your board and see if the problem follows the driver or again stays on the board. This might tell us the if checking the voltage is necessary.
Ok. I found a video of one and the schematic of mine.
Touch GND and what should the other be labeled? I don’t see vcc
