UM3 Error printhead moves into build plate!

[Pia92 0]

Hey there, 

 If I pause the print after a few layers, the print head moves down into the print and build plate before it moves up.

It happens all the time. It happens within the bottom layers. The leveling is manually but well. I think it does not happen within the infill.

I use Cura 4.4 and an UM3 with the actual firmware. 

I figured out that default there is a end g-code in my printer settings:

 

G91 ;Relative movement

G0 F15000 X8.0 Z0.5 E-4.5 ;Wiping+material retraction

G0 F10000 Z1.5 E4.5 ;Compensation for the retraction

G90 ;Disable relative movement

 

Is the issue there? 

 

Thanks in advance!

That gcode looks fine. 

 

Sounds like a new firmware bug for the Um3.  This sounds familiar.  @Dim3nsioneer - is this a new firmware bug possibly?  Is there an older version of the UM3 firmware that doesn't do this?

 

What version of the firmware do you have Pia92?

It can't be a new bug as 5.2.11 is out for quite a while now.

I would try a Cura Connect reset first.

FYI - "cura connect reset" is done on the machine and it fixes many many issues that have nothing to do with cura connect.

To answer this question:

The end script is not executed if the print pauses.

 

How do you pause the print? On the printer, in Cura, with a post-processing script, or...?

Sorry, for letting you wait.

 

I reset Cura Connect, it is still the same. Acutually, I am not even using Cura Connect. I start my prints from a USB flash drive.

 

I pause the print on the printer, no Cura command or script.
