Re: Low power experience

Once you hit 11 volts the motors will start to complain and make strange noises during a slew. We will change the parameters for operation at 12 volts with a drooping battery so that the motors will still slew properly and not put as much load on the battery.

Awesome. I always love new updates and things to play with. The battery was really low. I think it's output was 11v when I pulled the power and threw it on the 10A Bioenno charger.

I have looked at the battery performance of the Mach2 and I believe we have a software fix for it. Stay tuned and we will have some new software for you to load so that you can run off a low charge battery.

So like a buffoon I didn't have full charge on my battery but I let it run it's course as much as it could. Thankfully it made it through the imaging for the evening with no problems.

Hours later when I woke from my slumber, the battery was quite low. I tested issuing some slews before throwing the battery on the charger and noticed it never threw a low voltage error at all. Only motor stall was thrown (en masse, spamming the APCC error dialog). 

Previously, if my mount had low power it error throw that, turn the LED yellow, and stop. The Mach 2 behavior is quite different. Probably worth looking at.

Other than that one test, the Mach 2 was a beast. Awesome guided, unguided, and it really takes to complements well. 😁
