Auto discovery not working

[adammhaile]

I have a single J1S on my network and am trying to use sm2uploader from OrcaSlicer to upload my files. Unfortunately I'm having no luck even when supplying the IP address directly.

When I don't provide an IP it never finds any printer, even though I can ping it and Luban finds it perfectly fine. When I do provide an IP it still tries to auto discover (I feel like it shouldn't be doing this) and it seems like it connects but then throws an SACP error. See log below.

I'm running firmware v2.6.2 on the printer which it tells me is the latest.

Any thoughts greatly appreciated.

Please restart the printer.

I seem to have noticed a pattern in J1 when luban connects and disconnects the printer.

I will debug this issue. Thanks for your detailed fdbk.

Weird... yup, that works. What's stranger though is I had not run Luban to test until after it failed to work the first time (2 minutes after first startup of printer) with sm2uploader. One question... it still tries to discover printers on the network even with -host and still fails. I thought that providing -host disabled discovery? j1uploader does work with auto discovery... but nothing I can do with sm2uploader gets auto to work.

I'm having a similar issue on an M2 MacBook Pro when communicating with my Artisan. The app connects if I specify the host explicitly, but not if I omit that option. I'm running version 2.8 of sm2uploader. Sometimes I get this:

2024/05/28 11:34:43 Discovering ... 2024/05/28 11:34:43 Error discovering on 192.168.68.255: write udp4 0.0.0.0:59967->192.168.68.255:20054: sendto: no route to host 2024/05/28 11:34:43 No printers found

whereas other times, I simply get this:
