Okay, Found by chance this: https://forums.basicmicro.com/viewtopic.php?f=3&t=777&p=2677&hilit=absolute+and+quadruple+enc1#p2677 So changing the software from IonStudio to BasicMotion fixed the problem, which is ridiculous. Why allow updates of IONStudio which doesn't work and is no long...

boards without connectors or with B2B connectors
Hi,
Is it possible to purchase roboclaw 2 x 7A in small volume ie <10 without connectors installed?
Ideally like to plug the roboclaw onto another board, hence don't fancy the idea of desoldering!
Thanks,
Rob.

Re: Encoder question.
Thanks IMC support! Just came across this forum note ,10K pullups installed on the encoder outputs and works perfectly. On a full swing of the worm drive motor has a total range of 6447, it's pretty accurate +/- 2 Is there a method to store the position value if power is unexpectedly lost on robocla...

Re: Losing communication with Roboclaw,TTL serial and Raspberry PI
Managed to resolve, and don't know why. So I'm posting this if others come across the same issue. But what I did do was: 1. Clean install of Jessie lite 2. Install pyserial 3. installed python roboclaw software (version I had was the latest) 4. modified the config.txt and enable_uart=1 (possibly dou...

Re: Losing communication with Roboclaw,TTL serial and Raspberry PI
Hi, Greatly appreciated the reply. Downloaded from Pololu... Running Jessie Lite, RP3. Whilst I was updating Jessie, I thought had the problem licked.
