Mikael Engström[HTPXCFGKMPH3U] Questions:

I have been running the linisteppers for a while, but im having problems with the heat dissipation, the linisteppers are modified for a "Vexta PK266-02A" motor (i have paralleled the 1ohm sense resistors R1 and R2 with two identical resistors making R1 0,5 ohm and R2 0,5 ohm. the stepping mode is half step. 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.
