Can we speak to Heat and the effect it has on the stepper motors. Since the Extrusion Method requires a motor and the proximity causes the heat to spread to the motor, what methods do you guys use to control the temperature. besides bowden extrusion, or liquid cooling. any thoughts?

Went through the connections and found a slipped heat shrink that exposed the wires and caused a short.

This taught me that lost COM can be due to bad connection.
Thank you all for the input:)

After checking up on the specs for Nema 17 motors. I found
Temperature Rise: 80°C Max.

the motor was definately above 80C.

Next step switch out the motors and deploy direct fan with heatsinks.]]> Janski Mechanics Fri, 27 Jun 2014 21:22:58 -0400 https://reprap.org/forum/read.php?14,375389,375399#msg-375399 https://reprap.org/forum/read.php?14,375389,375399#msg-375399
Has anyone fried their stepper motor due to high heat?]]> Janski Mechanics Fri, 27 Jun 2014 21:16:40 -0400 https://reprap.org/forum/read.php?14,375389,375398#msg-375398 https://reprap.org/forum/read.php?14,375389,375398#msg-375398 jbernardis Mechanics Fri, 27 Jun 2014 21:10:08 -0400 https://reprap.org/forum/read.php?14,375389,375390#msg-375390 https://reprap.org/forum/read.php?14,375389,375390#msg-375390
I have 2 extra 40 mm fans looking to use it directly at the block and the gear / nema 17 plane.

Hope this makes sense :)
