Nema 17 on Pololu - overcurrent?

Hi,

My newly built Prusa with Megatronics and Pololu is giving me a hard time.

The first seconds of most prints go well, but then my X and Y axes begin to skip quite fast.
Same in pronterface.

I think I read somewhere this might be due to overcurrent? The steppers would protect themselves against overheating thus skipping G-code commands?

where do I look if I want to try if reducing the current would help?

thanks!

If it is overheating, you'll notice the steppers cutting out briefly in a regular pattern, as the chip overheats and cools.

You can adjust the current with the trim pot on the pololu itself.

Thanks!

It worked!
