@mrawesome987 said in Tuning E3D Hemera with Revo:

I preheated it to around 210, and it got to temperature, but then it dropped to 189 instantly and resulted in a heater fault. I am thinking that there may be something wrong with the thermistor (it's built into the heating cartridge on the E3D Revo). Since then, however, it's seemed to work ok.

I think you should contact E3D about that. I seem to recall some issues with revo thermistors.

@mrawesome987 did you remove the leadscrews to check them for straightness?

@mrawesome987 said in I need help choosing and finding a PSU?:

What are the big advantages to going with AC? Faster to heat?

No longer needing a large noisy DC PSU is the big one for me. Even a high quality +600W DC supply hums pretty loud under load not even counting the cooling. With an AC bed your DC supply can be sub 350W and whisper quiet. The added benefit of heating a +400mm bed quickly is nice too.

@mrawesome987 thanks for the update. I think the firmware must have been stuck in a loop in the Atmel/Microchip SD card driver waiting for the hardware to become ready; although in theory the transfer should time out instead.

@fcwilt @fcwilt I was testing a ton of different stuff and I ended up commenting those out.

I just found the problem...

;Fan M950 F0 C"fan0" ;Create Fan 0 M106 P0 S0 M950 F1 C"fan1" ;Create Fan 1 M106 P1 S1

The "Create Fan 0" and the "Create Fan 1" was not commented. I have no idea how this happened, because I certainly didn't change it after doing the firmware update.

Well I feel like I wasted your time, but thanks for the help!
