I've been through every video I can find to learn about the in's and out's of this (my first) machine. Here's the prob:
When I start the machine everything works fine. Pre-heat is quick and holds well. As soon as I hit 'build', the temp drops a few degrees and causes the machine to be in 'warming up' mode and eventually not print at all.. If I do get a print to start it usually takes less than 5 minutes for the temp to start rapidly dropping. Go back to pre -heat and it gets right back to 220.
I've tried files from Thingi as well as test prints that came with the machine. It is second hand with a new thermistor. I've checked the connections and made sure all is tight. At a loss and a bit sad....as is my daughter who's waiting for her first baby yoda.
Thanks for any help!
