Ramps Board Running Hot
Posted: Wed Aug 28, 2013 5:17 pm
I have more or less completed my Ord Bot build and I am presently held up by my QU-BD extruder playing up. While I am waiting for a new extruder pulley I have been running the printer through some dry runs to fine tune the settings and the calibration.
I noticed the RAMPS board runs very hot and I was thinking of installing a cooling fan. I measured the temps with an infrared thermometer. The stepper drivers vary from 39 deg C for the Z axis (not used much I guess) to 79 deg C for the X axis. However the copper heat sink on the power end of the board read 220 deg C !!!! Anybody fit a fan?
