thank you, i did loosen off all the screws on the brass couplings and i moved the rail down and loosened the z motors and tightened them back up again. I have run it all the way to the top and down again a few times with some lubrication and it seems ok now. I wont really know until I do a very big ...

So I updated to 1.38 luckily there were no issues
Now the motor tool 1.2 is working except for travel acceleration
I made my changes and pressed Apply. Looks like values have been saved. Will print something soon to test !
new settings below.

Really ? How ?

Hi William unfortunately this did not help

It will not read the settings I want, so I am not confident to try and write my new settings. Is there another way to write the acceleration and jerk settings please ?

I downloaded the tool from here
https://github.com/Geeetech3D/Smartto-Tool/tree/master/applications

unfortunately only some of the fields are read in while others are still blank

I want to update the Jerk and Acceleration but the Tool does not work and M503 does not return anything either
I have ...

This is a new printer so nothing is worn

Is there an easy way to check if the z rods are bent ?

I am doing a 3 day print, after day 1 the printer gets locked in z and keeps printing over itself, basically a big mess
I press pause
After I resume it goes for another day without issues
Day 2 printer locks up again
I press pause and restart then works as normal

I originally leveled the x rail to ...

After printing for 24hrs the right side is now about 3mm higher than the left. The printer was jammed on the same layer for ages until I paused it.

I’m getting the same issues, I did add some grease which made it better but yeh the tops of the rods are shaking, especially the right one.

I am doing a 3 day print and after day 1 it’s like the z axis just got stuck and the printer kept going over the same layer over and over. I decided to pause ...

Sorry William not sure what a driver board is... but sounds like overkill ?

I found another post who mentioned that they are 12v fans running at 24v which is why they are so loud
Solution is to add a resistor in series.
Will give it a go
