I'm only having overheating problems with my Y-axis. The psu is 12V 10A. Im using the CPU-heatsinks that i ordered from you along with the linisteppers. I have ordered a larger heat sink, that i will mount before running the machine again. Is there any more tips you could give me? would a difference in speed generate more heat? i adjusted my software to get more mm/min. the motors are quite warm 50-80 degrees celsius.
