hello everyone,

I am extremely new to 3D printing, and was hoping I might be able to find some help from some of you more experienced users. Everything seemed to be working fine for a couple days, but today after cancelling a print that failed to adhere to the print bed, it seems as though my Y-Axis is totally uncalibrated or something. When I hit “home”, the x and z axes have no issues, but the y-axis sort of stutters and makes a loud grinding noise. It does not reach the front left corner or the print bed, instead it seems as though it goes to the back left corner. I try to use the “move” y-axis function, and it just gives me loud noises and the bed shakes pretty hard. Can anyone tell me where to start in fixing this issue? I’ve tried googling and can’t seem to find any similar issue.

thanks!

My guess is a bad Y stepper cable. Pretty common thing to go bad. See if you can switch it out for the X maybe and see if the problem changes.

The Monoprice Mini, which I have and enjoy, has a bug in the firmware and it doesn’t handle canceled prints well. I’ve found that a power cycle after canceling a print takes care of the problem.

Sorry I disappeared; life came up and left me with no time to work on fun things. But it appears you might be right about the faulty cable. Could you by chance provide a link to the correct cable i should purchase to replace it? Is it the standard 4 pin to 6 pin that shows up in Amazon for “stepper motor cable”? I’m mainly just worried about buying the correct cable with the correct connectors. Thanks so much

I encountered this a couple days ago on my X axis and at this point I’m pretty sure it’s not the cable, at least for me. Try swapping the cables for the X & Y axis, then moving them using the move interface. If it’s a cable issue, the problem should stay on the same axis, but if it’s a firmware/mainboard issue it should swap.

I’ve got a ticket open with Monoprice about repair/replacement options, and I’ll probably try re-flashing the firmware on the problem board if I can get them to send me a new board without wanting the old one back.
