The G2 board... help!

Postby alberto2000 » 2018-Feb-Thu-15-Feb

So I finally jumped the gun and installed the G2 on my Simple Metal with Heated Bed. Installed latest (is it?) firmware G2CoreSimple1403.170421.bin using bossac and it seems to work. Using pronterface I can set the temperatures, move the motors, etc. But:

1. The motors make a LOUD hissing noise when on. It's like they receive too much current? Why is that?
2. So I tried issuing M906 / M907 to set the motor current for each axis but I get "code unknown" error... not supported by firmware?
3. The Printrbot documentation / github seems all so messy I'm not even sure if I have the latest firmware...

Can anyone point me into some direction? Is there a newer firmware than the one I found? https://printrbot.zendesk.com/hc/en-us/ ... rted-Guide

Thanks!
