Re: SOLO no longer detected by Windows

One point which is still unclear to me (perhaps a subject for another thread?) In battery-only power source scenario - how can one calculate if the "peak power absorption rate" of the battery is greater than the "peak power generation potential" of the motor? In other words, how ...

Re: SOLO no longer detected by Windows

Ok, makes sense - Thank You! To Summarize how I managed to kill this SOLO (Presumably applies to all RoboClaws): When using only a Power Supply instead of a battery to power a RoboClaw, and the battery voltage is set in Motion Studio to match the power supply voltage - the SOLO will send energy gene...

Re: SOLO no longer detected by Windows

Ok, thanks for your thorough explanation. Lesson learned - don't use a bench power supply without shunt diodes and power dissipation with a motor which can generate significant amount of energy (not inductive spikes, but generator). Alternatively, I will put a battery in parallel with the power supp...

Re: SOLO no longer detected by Windows

Ok, thanks for this useful information. My bench power supply does shunt the inductive voltage spike - it even makes a little click when the protection circuit is triggered - but perhaps it's not fast enough. Are there really no protection flyback diodes in the Motor A/B leads? Would you agree this ...

Motion Studio - Auto-Tune PID crashes app

Hello, Motion Studio 1.0.0.64 I'm using a SOLO 30A with a 600 PPR A/A Encoder with microswitch endstop on S3. After trying multiple times with multiple PCs and SOLOs, I have always experienced the same problem when trying to auto-tune PID (Velocity or Position) - it has never completed. Encoder work...

Re: SOLO no longer detected by Windows

Also, does the fact I'm powering it with a bench power supply have any significance? This problem seemed to occur when I was performing forward and backward movement (using PWM slider in Motion Studio) with small ramps - so quick direction changes. Also, I am not providing separate logic power, does...

Re: SOLO no longer detected by Windows

Regarding your comment about killing usb cables, I did try 3 different cables, no joy. For the USB port, I plugged a generic FTDI into the same port as SOLO - The FTDI is detected by windows as VCP. Even so, I did try using a different PC (which I have used successfully in the past with SOLO) After ...

Re: SOLO no longer detected by Windows

Hello, thanks for your reply. As I mentioned in my post, I believe I have already done all the troubleshooting steps you mentioned. I've even inspected the USB SMD solder joints with a microscope - they look ok (no cracks, the jack is firmly mounted to the PCB). Is it possible to put a SOLO Into DFU...

SOLO no longer detected by Windows

Hello, I Have been working with a SOLO 30A for a few weeks now. I'm using a bench power supply set to ~17V (to simulate a 4S battery pack) and a micro-usb connection to a Windows 10 Pro machine. The motor is being driven at <10A in closed loop with encoder and microswitch endstop (with 4k7 external ...
