Hello team!

Got my kit on Saturday evening and finished the construction on Sunday evening.
This morning made the adjustments and it worked - except for some runind printouts.
The reason were the motor drivers that got really [color=#FF0000]hot[/color]. But to find out, it took a time and a burned finger. I got some small heatsinks an an old PC fan and now it woks like charm.

My suggestion: add some heatsinks for the drivers to the kit. Or just an advice that they can get very hot and additional cooling is required.

Hi Eddy,

to what value did you adjust the reference voltage on the drivers? At 0.425 to 0.55 V, they should not heat that much …

Cheers,

Where can I do this? It’s not mentioned in the Assembly Manual.

It is not part of the build it is in the next step, the printing manual.
