After extensive testing, I have came to the conclusion that my Superplate will no longer stick to PLA. I tried cleaning with alcohol, cold and hot, with no change. Then I move on to stronger solvents. Denatured alcohol, mineral spirits, paint thinner, and even brake clean. After each cleaning ...

I ordered one direct from geeetech, $20 shipped.
have to wait for shipping from China, however.

If the firmware doesnt help, try using a different SD card, My pausing problems were caused by an SD that the printer didnt like.

I need to replace the Y axis stepper motor, It has been making a grinding noise that keeps getting louder. Vref is correct, belts and pulleys are all ok The stepper motor itself has a bad bearing or gear inside.
It is larger than the other stepper motors on the machine, part number 42shd0430-24b

My A30 has been very noisy, vibrating hard enough to move itself around its table, especially during fast Y axis movement.
I added TPU soft feet, nailed the table the printer sits on to the wall, replaced belts and pulleys, added a support bracket with double dampers to the Y axis, checked and ...

Has anyone managed to get the 2208 drivers working yet? I am interested in doing this upgrade. My machine is noisy and vibrates terribly.

I fixed my pausing issue. One particular SD card I was using would cause the printer to pause at random, it wasnt a firmware or a slicer issue.
I did purchase S3D, and I am glad that I did. There is a pre-set profile for the A30 in S3D that actually works, the thin-walled printing and support ...

The printer shipped with all of the lead screw hub to bracket screws loose. I mistakenly tightened them. Apparently the brackets are not completely straight. I loosened the screws again and the binding issue is gone.

If I use this firmware, must I replace all of the drivers with the tmc2208? or can I just upgrade the X and Y axis drivers?

I also made sure that no wheels are loose or binding, and checked that the beam is level with the rest of the frame using a digital level. I also replaced the stepper screw couplers because they were off-center, causing a wobble.
Should I try for an even higher VREF value for Z than 1.15? perhaps ...
