As long as you have the 2.54mm pitch JST connector, and that pitch is all that I've seen on my printer or the other "stuff" that I've worked on, then the DuPont connector will fit the pin spacing. You just don't have anything other than the friction between the sockets and the pins to hold the connector on, so the connector could vibrate loose.
Long term, I'd get the new connectors and eliminate the additional failure point of an adapter. Short term while you're in the "I just want to see it run" mode, the DuPont connectors will work just fine.

A blob of hot melt glue works wonders, and if not too extensive can be easily removed

Congratulations! I'm totally amazed that you got a good print with that few ugly ones!

Same here! It'd have been even better if I remembered to set the steps per mm on the extruder.

That's smart. I was wondering what'd happen with the connectors since I want this board mounted upside down.
Still considering what to do for an enclosure.
Something like this is similar to what i've done in the past, and i'd have half the materials. Plywood is appealing since you can easily screw stuff into it. The grey rectangle is the laptop since I think it'd be convenient to run the machine from that.
There's alot of talk about fire hazards so I was hesistant about plywood, but on closer inspections alot of it seems to be the result of crappy machines. It turns out they're disabling safety features like thermal runaway checks to save on program memory in the firmware, so they can use cheaper electronics. But it's still something i'm thinking about.
Also looking at commonly available building materials it seems like cement backer board is the only thing that's truly fire proof, but I can't imagine the dust being healthy for me or the machine, and sticking something like vinyl on it would defeat the point. There's glass too but I don't really want such large panels hanging about, especially on a machine that might get a little warm.
As for insulation - I was in the loft when trying to sort that water tank leak and found there's a few unopened rolls of rockwool up there. I could use staples to trap that behind some woven glass roving, to reduce the combustible stuff. The plywood would probably be enough but i'd also like to try insulate sound.
Oh yeah I also did the two pillars stringing test to check the retraction. Default settings seem fine with no stringing but one of the corners got a bit wobbly. I feel a part cooling fan might help with that.
WeldingRod:
I used polycarbonate for mine.
I wouldn't insulate; you don't want to get too hot.
I would make at least one panel transparent so you can check up on the motion.

Setting this off on a 3 hour run to see how it copes. When levelling the bed and moving the gantry around though the stepper motors seemed alot stiffer than they were. Are the bearings failing already?
Edit: Ah it turns out it's because they're plugged into the board, and it must be sending the current back into other windings. I was worried something was failing already!
