so i guess the MMU isn't power loss safe?
i have my printers on large APCs and had a power spike during a MMU print which reset the printer somehow (didn't cause this before when it was just a MK3, i guess part of the MMU2 firmware change. so the printer reset, and recovered but the MMU just sat there with all 5 lights slow flashing refusing to respond to any input, it was completely locked up. had to stop the print and chuck it, and power cycle the machine so the Selector would unlock during the power on self test and alignment then it was working as normal.
any quick tips on this in the future?

Re: so i guess the MMU isn't power loss safe?
ok i found the gibhub ticket on it. n/m
the MMU is seeing the stepped sine wave from the APC and going into error mode because it signals bad power. the rambo appears to have no problem with this but since the MMU is connected on the main supply to the rambo then both see the bad power signal but the MMU cannot recover.
possibly using a pure sine wave APC might keep the MMU from going into error mode.
