The motors make useful hand warmers this time of year :-)
Mine run on the edge of too hot to touch and I haven't had any problems yet - 80 degrees C above ambient seems a common maximum.
hahahah!!! nice one chris... its ages since i was in that position watching them motors turn on the road runner g-code
it was all magical mystical shit to me (still is a bit)
iv got the 5 axis version of your board, my motors are a bit bigger than yours and dont really get hot at all on 24v, iv heard plenty of people reporting how hot the motors get, i think in some cases its pretty normal
What motors are those Chris?
I hope not... 85degC absolute case temp is the maximum recommended temp you should run a stepper at - higher than that and you risk internal breakdown and demagnetisation.... remember inside its going to be a lot hotter!Quote:
