Thanks @Jaesin
That was helpful to confirm my suspicions about the port.
I can confirm that it’s likely a problem with my octoprint setup/build.
I can manually send commands to /dev/ttyS1 from the user running octoprint, and the printer accepts them
zim@zim:/root$ echo -e “M1202” > /dev/ttyS1
turns on the light
However, octoprint still just times out. Will dig deeper on that side.
UPDATE: well, i changed away from auto, to force it to /dev/ttyS1, and while it fails on first connect, it connects on subsequent tries. Weird, but I’ll take it. Thanks all!
to anyone else who has a new zim, or hasn’t converted to OctoPi, using the cubie board was fairly painless. I’ll upload my notes/instructions in another thread, but for the most part, just follow the zim-oprint and zim-bootstrap instructions, they were super helpful.
It was nice to not have to remove/replace the glued in USB port, nor open up the zim at all to get it running octoprint. I’ll eventually yank out the cartridges, and install spool, but seems to be alright for the moment.
