4 years ago Hi,
I am looking to add support for Flashforge Adventurer 3, and I was wondering how FlashPrint is doing the autodiscovery of printers in the network, with some Wireshark I'm now able to do auto discovery, and in the process of a proof of concept based on
UM3NetworkPrintingplugin for FlashForge Adventurer 3.Apparently the printer is listening for a multicast packet on
225.0.0.9:UDP:19000and with a crafted payloadc0a8012b46510000(I have not ideal what the payload is) it will reply with the printer name:0000 4d 79 20 33 44 20 50 72 69 6e 74 65 72 00 00 00 My 3D Printer... 0010 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 0020 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 0030 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 0040 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 0050 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 0060 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 0070 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ 0080 e1 00 00 09 22 c3 2b 71 00 08 00 00 ....".+q....Below is the sample Python for sending the magic packet

Hi, Are you trying to connect via USB cable and print?

Is your feature request related to a problem? Please describe. I would like to add support for FlashForge Finder in Cura. I did a little scripting already and have some pieces that I would love to put together. I own a FFF and it is a good starter printer. I use Cura with it already but did several hacking to get some things working, so having a few of them ready from Cura itself would be awesome.
Describe the solution you'd like I would love to see Cura support for Finder as a Machine Definition built-in, so users can get it ready to use more easily. I can create the definition with the data I used already in the UI so it would be cool, just need proper directions on how to proceed.
Also, would like to support some features like sending the job over wifi. Today I operate by uploading the g-code from Cura to a cloud provider as I don't have a USB stick (odd, i know!). Then I use the built-in firmware feature to download from cloud and print. I would love to implement the functionality to send the print job over wifi and keep monitoring it over as the printer allows it using TCP. I have some pieces like a custom GX code writer that the printer uses and allows a print preview image to be displayed in LCD (testing yet).
Finally, I have a small script to work around the "Pause at height" solutions from default Cura that oddly don't work with Finder (printer goes nuts if I use them). I implemented a small script to allow to use the M25 command that the printer understands. Would like to ship it (or a version of it using already existing plugins) to avoid a set of trial and error for other users.
Describe alternatives you've considered I am using these for a year and think this would be a good addition for an upcoming Cura release, as I often find users on Forums that don't know how to get the job done with Cura and may be losing a lot of good features from it.
Affected users and/or printers Only owners of FlashForge Finder that don't like/can't use the provided Slicer software.
Additional context I need some guidance in order to get things done but I'm all in to send pull requests and get feedback/review. I also can code in Python and have the printer so I can test different things until we get it ready to release.
