I am printing with a UMS5 an item how takes 23+ days to print and needs 100% infill and has a ratio of 1,5 hours printing of PLA and only for 30 seconds of PVA. After a day 7 I got the message that the PVA was running out of filament. The PVA was not empty but clogged up in the extruder. I use the option "Change Filament" to get the extruder going again. about 7-8 days later the same thing. So for the continuation of this print I did the change of filament every 5 days, the final print will be ok. My question is , will adding the "Prime Touwer" taking care of this problem ? Or, setting the standby temperature of the PVA (is now 175 C) to a lower setpoint, say for example 50 C to keep the PVA dry in the extruder. I assuming that the software will take care of heating up the PVA in time before it starts to print. And how clever is the printer software ? will it calculate the heat up time before the PVA is needed to print, or wil it just halt the printing process heat up from 50 C to 215 C, instead of 175 C to 215 C ?

During a print of 23 days, about halfway there was a 10 seconds power cut. Lost the print (it was already 11 days printing..) after cleanup restarted the print again... My question is does the software of a Ultimaker S5 any way capable to communicate with a UPS? So if there is any power cut, the ups takes over, send a signal to the S5 how will stop/pause the print in a proper way and wait until the power is back again and continu printing ?
