Cura 3.3 - Bug in Pause at Height Plugin

[berndjm 16]

If using the Pause at Height Plugin with layer-numbers instead of height there is an unexpected move to x 0 y 0 before resuming the print.

gcode with pause at height:

 

gcode with pause at layer:

Sorry if these are dumb questions:

1. If i used the extension in that way, how would the bug manifest itself?  I tried this over the weekend (and should have done so with a test print), but I ran it on a piece I was hoping to be a success and, when I resumed, the bed continued back upwards right into the nozzle, creating a burn hole in the print before I had to manually stop it.  It also caused the filament in both spools to retract way back into the PTFE tube, causing me to essentially remove all of the filament and refeed it to start over.  I did the pause at layer and not at height.
    
2. This is my first time using (or even finding these extensions).  How likely/quickly will an issue like this be resolved?  Does your discovery have a fix we have to wait for or something we can/should do ourselves?

Thanks!

 

UPDATE:  I think the Z in the bottom code is also a bug. That might explain why my print crashed into the head on resume.

 

Either way...Good catch!!!

 

 

Here is my examples of height vs layer:

I can confirm what is stated above. I'm on Cura 3.3.1 and have had the head crash into the piece when using pause at layer. Hopefully this gets fixed. I know it can be edited in the GCODE manually, but the reason for using a plugin is so that you don't have to edit the code by hand.

 

Thanks for looking into this.

@chuckmacgee:

You're right. In my test-case I didn't realize that the Z1 is a problem, because on 0.2 layer height pause at layer 5 = Z1 ?
