Re: Issues with 4.2 firmware
I tried the new firmware and got similar inaccuracies in the voltages. No errors this time, but I depend on the voltage for SOC monitoring. Version 4.2.1 showed main battery voltage 11.1, logic 0.5 Version 4.1.34 showed main battery voltage 12.8 logic 0.6 The reading were a few seconds from each oth...

Issues with 4.2 firmware
I just went to change the tuning on my 2x45A and it auto-updated to the latest version of motion studio (including 4.2 firmware). I went ahead and updated, but immediately it was giving logic battery low errors and the main battery voltage appeared low as well. I even set the logic battery low level...

Re: Current way off
Also, quick follow up question: Will the Roboclaw attempt to protect itself using the incorrect current reading? It doesn't seem to be doing it at the moment, but I'm also driving it pretty gently at the moment.

Re: Current way off
That's correct, it's showing significant current even at 0 duty. The board is powered by two 35AH SLA batteries in series. The motors are two Quantum wheelchair motors... not sure on the specific model. They're rated for 24V and 200 watts continuous. Are there any other specs that would be useful? T...

Current way off
I just installed a new Robotclaw ST 2x45 and the current readings seem very off: While motionless: M1: 25A, M2: 4.5A While in motion: M1: 53A, M2: 10A Any ideas what's going on here? Both motors are identical and an external current sensor shows no current while idle, and about 15A while in motion. ...

Re: Sealed cooling
It's in a black plastic enclosure that it also shares with a Solo. So basically the worst of all characteristics. Sounds like I need to hunt for an aluminum enclosure and see how that goes. Bolting the solo to a metal enclosure should take care of that one, and the 2x15 should benefit as well. Thank...

Sealed cooling
My project has relatively low power requirements: 24VDC with ~1A per channel on the 2x15A roboclaw. Originally I thought I could get away with just putting it inside a sealed enclosure, but on hotter days the controller has been getting scary hot (90C). Unfortunately my project is in a very dusty an...

Re: Intermittent Communication Issues
Thanks, I think I'll drop it all the way down to 9600 and see if that fixes it.
What's the most reliable way to connect to the pin headers? The connections are soldered to the ESP8266, but I have to use those silly crimp-on pin sockets for the Roboclaw side.

Intermittent Communication Issues
I've been using the Roboclaw 2x15 with great results for the last couple weeks, but the last few days it suddenly started intermittently reporting 0 volts for the main battery voltage and the motor currents return identical values (normally they randomly fluctuate). I'm using an ESP8266 to communica...
