Hey all, Throughout our testing phase with the BlackBox X32, we seem to have finally done something it didn't like and it hasn't acted right since. We believe something got fried, but we don't know what. It lights up when powered, but it doesn't connect to any PC and it doesn't energize the steppers or respond to any input. Is there any possibility of shipping it back for repair? We already bought a new one and have been using it in the meantime; we just hate having an extra board playing paperweight... Thanks!
We don't offer a repair service, sorry, but if you have any ideas what happened to it, we may be able to offer some insights on what it may take
Totally understandable. It's been a little while now so the details are a little fuzzy, but best I recall, we had connected a bldc motor controller (an esc) to the pwm output from the blackbox. The documentation with the esc was not very good, and long story short we connected the pwm to the throttle input for the esc and shortly after, the blackbox just stopped functioning. No pops, no smoke, just a sudden disconnect from everything and a de-energizing of the steppers.
So the PWM port is directly connected to a GPIO pin on the ESP32. If the backfed voltage caused damage the ESP32 itself will be the victim. You'll have to be able to do SMD rework to replace the ESP32, but they are around $4-5 so if you try / know a guy - shouldn't be too hard
