Sometimes writing a monthly update feels like a therapy session – writing down all your problems and hopes, and hoping someone is reading it.

The February Mainsail update is out on Patreon! This month: a massive init process refactoring, new HappyHare features, Vitest integration, and the honest confession that I'm increasingly becoming the bottleneck of my own project.

Re: #3dprinting

#bdsensor was a bust because I use an ultra-flat, #MandelaRoseworks heated bed with embedded magnets. Magnets unfortunately fuck with Eddy currents and thus no bueno.
It's unfortunate, I really like the technology and being able to do a scan of the bed by just running the probe across it is awesome and high density scans take essentially the same amount of time as low density ones. Nothing like a 30x30 bed mesh created in under 20 seconds. But alas, I'm back to the #BLTouch. It just works despite not being "best".

I spent a weekend converting the system to #Klipper and while it works, I haven't noted any big benefits compared to Marlin.

In fact, because I need to write macros from scratch and at some point figure out how to use the LCD on the printer, I'd say it's overall more complex. For some reason it's also running slower.

That said, at some point I should be able to wire in an #ADXL345 which will help me deal with harmonics better.

Lastly, I think it would be awesome to use the nozzle as a probe, so I have passively been pondering how to mount #piezo sensors to do so. But my platform wasn't designed for them, so I will probably need to make hardware of some kind.
My thought at the moment is a disc with a lip on it so that it will hold the piezo sensor away from the bed, and then use a aluminum spacer around the bed screws on top/through the piezo so that anything pressing on the bed transmits down to the sensor.

All in time.

Trying to preheat the bed on the #SovolSV08. idle_timeout does nothing, apparently, because the bed still shuts off after ~10 minutes.

I don't want to try to understand these macros people have posted, so instead I'm going to use a #HomeAssistant automation that simply tells the bed to heat, waits 10 minutes, then tells it to heat again, etc.
