[Issue with cura 3.2 and monoprice select mini v2]

Good idea. I don't know if the OP can edit the title or if it might require a mod to do it. 

[Issue with cura 3.2 and monoprice select mini v2]

I noticed when I upgraded Cura today that anytime I tried to any the monoprice mini select, it would crash immediately. After digging around it looks like the problem is in the malyan_m200.def.json file. It is used for providing definiations for the MP mini select. To fix the problem edit \Ultimaker Cura 3.2\resources\definitions\malyan_m200.def.json

 

About 2/3rds of the way down there is a line

 

"material_diameter": { "value": 1.75 },

Change it to

 

"material_diameter": { "default_value": 1.75 },

 

save and all should be good. Hope this helps
