Hi Robin, i had a bit of trauma a couple of days ago, one of my X axis motors started losing stepps.... lots of them... i hate making scrap

took me a while to suss that it was heat realated, i turned the fan up to full on the driver heat sink (5 axis all in one job)

i was really starting to trust this machine im a tad twitchy now ... its been ok now for a couple of days..... fingers crossed
