So this is in my configuration.h #define DEFAULT_AXIS_STEPS_PER_UNIT { 79.89, 80.36, 2603, 95 } //Orig { 80, 80, 4000, 500 } 93*2 = DRV8825 1/32 Stepps Because I have threaded rod NOT Lead screw. I have disconnected the screws from the Z-Axis steppers. And I STILL get the same noise. It is as if one...

Its not a bearing, in the 2nd video it was a combo of the shafts and the screws being very bent.

the problem NOW is firmware, Im sure of it.

Hi, you need to install your z-axis fixing plate.

This was also part of the problem,

The top plates? I removed them as the threaded rod is so warped, that it rocks the X Axis up and down as it travels on the Z. You will notice that I have red caps on top that hold the guide rods, allowing the threaded rod to spin freely. THIS got rid of my wobble. But that is not the problem, the pr...

I have been trying to update my Pro C to Marlin for some time. Its having z axis issues when doing a rapid movement.

Here is a Video that can better explain the issue.

All I found was a .hex file, but I have installed new steppers, and THAT helped with 1.1.8 on my GT2560 Rev A.

Hi, you can refer to this: https://www.geeetech.com/download.html?download_id=35
and the proc don't use 1.18

That link is to a Hex file, not a Marlin / Arduino download. perhaps for an other board?

I have 1.1.8 on my Pro C, and.. My i3 Pro C running Marlin 1.1.8. on a GT2560 Rev A. Things are moving MUCH better now. But, I have run into a problem with the Z Axis. When Z Steps_Per_Unit = 1280 The z moves nice and smooth. But only half the distance ie. 10mm of indication = 5mm of movement When Z...

yes, there is a heated bed under the glass. My machine is a Pro C.

I have checked that the glass is flat, using a straight edge. And the glass is flat.
