Hello I’m new to 3d printing, and new to 3D HUBS. I own an anet 8A, I have to say this printer have been a learning experience since the beginning, form the poor translated instructions to the mislabeled cables. But I can say I really enjoy the process. I only have managed to print one cube. Yesterday when I was printing the second object the y axis started to behave erratically with a jerky movement and no real displacement. I’m not sure what it can be. I’m sure the stepper motor is ok because I switched the y and x cables and the y was running smoothly and x was the one with the problem. It means the problem may be the board. Please any help or suggestions will be very appreciated.Thank you in advance.

Is there anything obviously wrong with the board like a burnt component or loose/badly soldered joint?

does it happen if u move the head from the printer’s panel?

When you refer to the head,are you referring to the top part of the printer where the LCD is? If so no,I haven’t. I only have removed the belt from stepper motor Y and the board to check it out. heatbed runs very smooth without the belt. The Y stepper motor behave the same way without the belt.

u said u changed the x/y cables and then the X motor works bad, so is not a motor problem. try to move the X and Y axis from printer control panel. not from gcode.

6

I did, when I moved the Y axis from the menu, I got the same result, the bed just shake and no movement. The weird part is when I send all axis home Y move fine weird nose but it move.

Board look perfect no signs of burnt component,I’m starting to suspect it could be a bad stepper driver… there Is any way to test them?

8

now what if exchange de x/y cables and test again from panel?

Hi, if it works only during homing maybe it’s a wrong set up of y speed, step/mm or acceleration, check it out.

If it’s a bad configuration of y axis also check your start/end gcode of your slicer, maybe the end gcode of the first print changed some settings.

Same result I’m starting to think the stepper driver or something on the board is fried

now is contradicting with what u said first: when u exchanged the cables u said the X has problem. this is not the same result.

Ok I unplugged x and y cables from the board only no from the stepper motors and switched them, to test the actual ports of the board, after switching them x had the problem, and y was just fine but obviously in the wrong axis, I guess you was suggesting to switch the whole cable in order to test the cables, I did it and the cables seem to be working just fine no mater where a put them the problem keep coming from the y port on the board
