Re: Firmware 4.1.34: Power Cycle required when enabling Limit/Homing Switches
Do you have any update on this? I've not had a reply to the email you requested.
I'm guessing this is low priority. Can you therefore suggest another type of controller on which the limit switches work correctly on both motors.
I've had enough of breaking stuff due to this 'feature'.

Re: terrible spikes with PWM mode
>Can you show scope shots of the 15s and 200ms spikes you talk about?
I think they already have!
If you look at the timebase on the scope, it says 40.8S. The repitition rate of the pulses is about 15S on that basis.

OK, I've sent an email containing all the details I could think of. Sorry for the delay, but also due to Covid I was unable to access the machine until Friday.

Re: 4 Motors - Position / Velocity tracking
Thanks. I was gradually coming to that conclusion.
I started with the Auto-Tune result - and gradually increased the I term until it was very close. Close enough.
The 3mS calculation / movement interval is interesting - may be useful one day!

Re: Firmware 4.1.34: Power Cycle required when enabling Limit/Homing Switches
I've tried this dozens of times, exactly as you describe - and it still does not retain the value for S5. The sequence I've followed is: Set S5 to Motor 2 (Limit Both) Write Settings from the menu Disconnect Drive in BasicMicro Studio Unplug USB Disconnect power to board. Power up board Plug in USB ...

Re: Firmware 4.1.34: Power Cycle required when enabling Limit/Homing Switches
That doesn't work for me!
It remembers the state of S4, set to Limit(Both) but not S5. It's a bit of a machine-wrecking bug!

4 Motors - Position / Velocity tracking
I have a platform, lifted & lowered by 4 linear actuators (DC Servo Motor + Encoder + Limit Switches). I'm using 2 x 15A Roboclaw Dual Channel controllers connected to an Arduino through Packet Serial. I need all four to stay locked together, so the platform stays level. I've tried closed loop V...
