Support Monoprice Delta Mini V2

[war4peace]

I have installed the plugin, however Cura (4.12.1) doesn't recognize Monoprice Delta Mini V2.
Error message is "Could not connect to device."
The printer is online and connected to Wifi, Wiibuilder can communicate with it.

Hi @war4peace

Thanks for reporting this issue! I do not own a Monoprice Delta Mini V2, so the support will be limited.

1. Could you email me your stderr.log? If you are using Windows, it is located in C:\Users\<user>\AppData\Roaming\cura\stderr.log.
2. Does the Monoprice Delta Mini V2 have a Web UI? For instance, if the printer's IP address is 192.168.0.100, can you control the printer via http://192.168.0.100?

Did some research. This project suggests the Delta has a Web UI. Supposedly the Delta has a similar API to the Mini V2.

@war4peace
In addition to stderr.log, can you share what you see if you access http://<your_printer_ip_address>/inquiry?

Hi @loociano
Sure thing.

I have no web access to the printer, this is what happens if I access http://printer_ip_address
I get a blank page with a row of text saying "This URI does not exist" - same if I add "/inquiry" at the end.

stderr.log:

Needless to say, I can use the printer just fine over wireless with the Wiibuilder application.

Also, the manual never mentions a web interface: https://downloads.monoprice.com/files/manuals/21666_Manual_210224.pdf

Hey @loociano,

I just subscribed to this issue, as I got the same issue. Running a linux pc though, Wiibuilder isn't an alternative and therefore I am highly interested in this patch. Let me know if I can do some testing for you!

Very best,
Jeroen

There's a reverse engineered http API. One might fork this repo to add functionality (I'll look into it actually).

[loociano]

Thanks @ayman for the lead. Clearly the Delta V2 API is completely different from the Mini V2 API, which is way simpler.
