Taz 7 X Axis leveling slow
Closed, ResolvedPublic

Description

My Quivers sometimes level the X really slowly, my fix has been to turn the machine off and on again, this fixes it.

@anolen I am pretty sure the leveling sequence uses the feedrate of the last command that was sent to the printer. @marcio is this correct? can we set the feedrate of the level so it is the same regardless of moves sent to the machine prior to the level command?

This should be fixed with newer FW. A feedrate was added to the level gcode. Its a little slower than what it was but that was to help reduce binding T4941

The X axis level isn't working well for me with the recent changes, it just bounces off the tops alternately and doesn't reach level.
I have just been leveling manually by turning motors off, shoving X axis all the way up and holding it while pressing the auto home button.

You can see in the video how it just kinda dances around and doesn't end up level.
@anolen is this what you were seeing or slower?
For the record I am running 2.0.0.63 per approval from @DaniAO

Almost, I was seeing it a little slower on mine but not by much.

The X Axis leveling isn't attaining level, this is causing error for the auto nozzle calibration because the process includes the automatic X axis leveling. The nozzle offset values provided by the auto calibration are nowhere near correct, especially the Z nozzle offset. Multiple vernier prints must be made to correct the X/Y offset values from those provided by the auto calibration as well.
I would prefer to be able to manually level the X axis without the auto calibration throwing it off again, but I doubt this is a viable solution for customers.

I believe the z nozzle offset is a different issue. Every time ive calibrated my alpha ive had to manually adjust the z offset. We are looking into another solution for leveling the x

But it would make sense to me that the z nozzle offset is wrong if your X axis isn't level. I have to recalibrate every few prints because things start being inexplicably off whether it is z offset or nozzle offset.

From what I've seen T5206 is a good solution to this issue

T5206 is now merged into master so closing this one out as it appears to correct the bouncing during x level.
