The version of WiiBuidler that ships with the MPMDv2 is Wiibuilder2.1.2.1 from Febuary 2021.
The newer version have several more features including an auto-update function (not tested by me)
The the latest version of WiiBuilder can be downloaded from WeeDo3d at http://www.weedo.ltd/download-2/ you can use any version listed as far as I can tell, but you MUST edit the printer profile to have it recognize the MonoPrice pritner correctly.
Here is how I did it, other ways will problably work...
go into the directory
C:\Program Files (x86)\Wiibuilder2\data\profile\jsonProfile2
make a copy of the profile direcotry for the printer you are using, it should be appaent which one.
Uninstall WiiBuilder to be safe.
Instal the updated version of WiiBuilder that you downlaoded.
create a directory for the profile files can copy the files you backed up above into thisdir, I did
C:\Program Files (x86)\Wiibuilder2\data\profile\jsonProfile2\MPMiniDeltaV2
navigate two level up to the driecotry
C:\Program Files (x86)\Wiibuilder2\data
edit the file
C:\Program Files (x86)\Wiibuilder2\data\machine.xml
at the beiniing just after
--VVVVV-- copy the lines below into the machine.xml file save and you should be able to open WiiBuilder and select the MiniDelta v2 as a printer --VVVVVVV--
