End G-code in machine settings causing issues

[Fishhooks1945]

PopOS! 22.04 Cura 5.1.1 latest dremel and autotower plugins, 3D45

I tried printing a retraction tower, and in the end made a big mess.. the machine just stops and tries to inject a ton of filament into the top of the tower. https://youtu.be/JF6ziO7qqOA
For example, here is the end of the gcode for the retraction tower.

I realize that Dremel Plugin's "G92 E1, G1 E-1" is just a standard retraction at the end of the print that everyone does. However, I checked a few others printers (utilimaker 3, ender 3 pro, prusa) and it seems this Dremel plugin is the only one that uses the "G92 E1, G1 E-1" method, where most do "G91, G1 E-1".

I changed the end g-code manually in my machine settings to "G91, G1 E-1" retraction method, and now my tower prints OK. 5axes's calibration shapes plugin has almost 1 million downloads (and AutoTowers plugin is an extension of 5axes plugin), so I think it makes sense to change the dremel plugin's end g-code settings to be more compatible and people make happy towers :) I also add comments to the End G-code for easier understanding and debug:

; Start of End G-code from Dremel 3D45 machine settings
M104 S0 ; shut off extruder, then bed
M140 S0 
;G92 E1 ; not compatible with cura plugins, !standard practice
G91 ; relative positioning
G1 E-2 F300  ; compatible, gets same result as original dremel file
G90 ; back into Absolute positioning so print present works
G162 Z F600 ; not standard marlin
G162 X Y F2000 ; proprietary? yes, this is makerbot\thingiverse lingo
M84 ; disabble all steppers
