Upgraded firmware now having many problems including self test, bed leveling and first layer.
So I upgraded the firmware last week. Now the self test fails at x axis length, the PINDA doesn't find the calibration spot, I'm getting random globs, and my first layer looks terrible, even after hours of bed leveling adjustment. Maybe I should go back to the previous firmware? I don't know what other info you need, just just ask and I will provide it for you. Any help is greatly appreciated. Thanks!

Hi,
I'm pretty new at this, so I might be wrong, but have you tried redoing the first layer calibration? It would appear your nozzle is a bit high yet. At least that is my problem when my first layer looks like that.

Join the crowd! As I brief over the threads to find and answer to my problem, I see that there are more threads with the same problem I am having.
It has to do with the new firmware upgrade. I upgraded and have the same x axis problem as you. I saw the same problem on another thread.

It might be worth doing a factory reset and recalibrating. This is sometimes necessary when moving between firmware versions with significant changes, and the changes from v3.8.1 to v3.9 are many.

Same issues here. Do you mean factory reset when using the wizard. If not please tell me how to factory reset.
I need to go back to previous firmware before these errors drive me crazy. Just did a resoldering job on my heatbed to get rid of the mintemp bed error and that was probably a total waste of time and work which now may make my bed vulnerable to a short.

Factory reset didn't help me:
Press and release the reset button (marked X and positioned under the control knob on the LCD panel) Once you see the text "Original Prusa i3 Prusa Research", QUICKLY press and hold the control knob until you hear a beep. Release the control knob.

Azaffiro honey I found the solution. The following steps worked for me.
1. Followed your instructions for reset.
2. Went into calibration and did belt level check because my x axis was only going to center of bed when i moved manually (printer off).
when it started belt level check it moved all the way across in all directions of both x and y.
3. Did xyz calibration.
Now lvelling my z with calbration.
Try that.

Just finished my first print. I printed a remix of the hotbed cover plat that directs the wires to an angle so they don't bend. I modified the hole to be bigger to fit the new wires that have shrink tupbing as this made them to bulky for the original hole. I am also going to modify the cover more so that it has curving channel guide the wire along the backside of the bed to hold the extra length of wire i added to the cut thermistor wire i soldered. I wanted to make sure there was no tightening of wire and more slack. here are some pics of my first print since fixing.
I am happy with my printer again until it fails again. Resetting to factory defaults seemed like it gave the printer a relief I think.

I wanted to add this file. Try this calibration square. It is much better than the factory first layer calibration.
You can adjust z while this calibration square is printing so you can see where you need to set your z height. When you start the print press the knob then go to live adjust z and turn the knob until you get the right adhesion and squash of plastic on the bed. It is a live adjust z calibration using pLA.
