Just finished my Hesine 505, It's a Prusa i3 clone with the melzi v2.0 board.
I was running the printer after I finished it and got all the software working and finally connected to the
controller board.
It probably ran a total of 3 to 4 minutes and I stopped it to check everything. Noticed the stepper drivers on the Melzi board are pretty hot.
You can touch them but not for long. I didn't have a chance to put my IR temp meter to it and read the actual temp.
What would be considered normal with these drivers. I want to say it has the 4988 drivers but I cant find it
anywhere in the documentation.
Any Ideas or am I overly concerned over nothing?
