Keep your stepmotors cool !

Dear Golem,

We had a stepmotor running hot due to high workload, high voltage (70 VDC) and amperage (7.5 Amp running). This video shows a cheap DIY solution to cool your stepmotors. The water running throught the cooling tube is running in series to the milling spindle coolant.

Be simple, buy our 5 euro solution instead !!!!
