Hi.
Recently I've "upgraded" my UM2Ext and closed the build chamber.
I've also changed the position of the motors and they are now mounted outside (I even added heatsinks to the X and Y motors although they are pretty cool.)
The ABS printing has improved much and almost no lifts occur.
The temp in the top of the chamber is around 60 degrees C. and it is achieved only by the heated bed.
I would like to crank it up to 100 C. in order to eliminate internal stresses inside the printed item and to 100% eliminate raft lifts during printings.
I was thinking about adding a closed loop system comprised of a heating element, a fan, thermocouple and a CPU, such as Arduino (I'm not aware/ sure if the UM2 motherboard could run a script for a separate heating system nor provide the power for one).
I'm pretty sure you can buy a COTS heating system, or someone probably have done something like that.
Any thoughts ?
Sincerely, Guy.
