Support for BTT UPS 24V V1.0 with BTT SKR mini E3 V2.0

Marlin Firmware Service Feature Requests

Hello,

Could you please add support for BTT UPS 24V V1.0 with BTT SKR mini E3 V2.0 board? It would be nice if this is available in firmware builder as well.

Regards
Rejish

I’ve put this on my TODO list - although I can’t give you a timeframe right now.

If it can be disabled by default, but turned on via a G-Code command, then that would be my preferred option - then it can be included in the nightly builds.

My understanding is that, if it is made available in firmware builder then regular builds need not to be disturbed and those who want it, can have it through customisation. Anyway, thanks for the prompt reply!

I’ve got this option available in the current test version of the site - so it will become available in the Firmware Builder on the next push to the live site.

I tried the power loss option newly added in firmware builder without success. Printing continued after power failure until the UPS discharged completely as if it did not detect the power failure. Is it PC12 pin configured for detecting power loss? For mini E3 board, its PC12 as per my understanding. Am I missing something?

Yeah - the power loss doesn’t work on UPS - its for last minute protection when the mains power dies to the printer. The printer will have no way of knowing if you’re running on mains power or UPS backup.

You would need to enable it in your G-Code as well: Power-loss Recovery | Marlin Firmware
