My prusai3, clone, does not reach its preset temp when starting up along with the bed. If I set the extruder to, say 250, and not turn on the bed heater, it works fine. If, however, I have them both turned on, the bed reaches the set temp but the extruder can’t get to its temp. If set to 250, it might get to only 235. The bed will reach its preset. I recently put in a slightly larger capacity power supply, and a thyrister controller for the bed. Any thoughts why this is happening? Thanks for any help.
