Thanks for the suggestion. I stumbled across a couple of posts here with similar problems that suggested increasing the pulse width. I did that and have not run in to the problem again. The comments also suggested that this issue seemed to be tied to jog speed - which explains why I could do a G0 and not a G1 (the G1 was 1 ipm and G0 is something like 10).
I also notice that Gecko has a tech note on heatsinking or using a fan to keep the G540 cooler. Interestingly, I just turned up the heat in my shop today so some epoxy on a fishing rod I am building will cure faster. My G540 is just sitting on my wooden desk while I am getting things set up. I've almost got the electronics box completed. I will be putting a fan in to that.
cheers,
Michael
