I second that.
When faced with a problem such as this, a conversion to 24 volts is less a question of "why" than a question of "how". In my mind anyway.
There are other threads that cover that subject in great detail of course so it doesn't bear repeating all the steps here.
But suffice it to say that if having to replace the original PSU with a quality version anyway, the added cost to convert everything else to 24 volt components is relatively minimal.
The original 12 volt system appears to have happened because an earlier design was simply scaled up in size without adequately considering the added load to the PSU and connectors.
Motor, bed heater and PSU problems were the consequence for many users, despite success stories.
