Hi folks! Long time lurker here, finally made an account to reach out to the community for a little bit of help. I’m nearly done with my second build, a dual rear with pneumatic tires (build thread to come once finished) and I’m having strange issues with the two DIYElectricSkateboard 4.12 VESCs I’m using in it. I’ve successfully set parameters and even done a small shakedown run with them, but now that I’m tweaking for final assembly, I’m getting weirdness.
When I plug in the loop key, everything powers up, all seems well. I squeeze the GT2B trigger, the wheels spin. If I keep the motors spinning for ~30 seconds, both stop, and will not start again. Motor detection also only works once or twice, then refuses to work again. If I unplug the loop key and let everything sit for 20 minutes, I can get the same response again. It almost behaves like the VESCs are overheating, but everything is stone cold.
I’m running 10s with 6354 motors. I have the current limits, voltage limits, ERPM limits etc set correctly, the damn thing just seems to go on strike after 30 seconds. Has anyone experienced this? Does anyone know how to fix this?
I’m definitely upgrading to a VESC 6 ASAP, just for peace of mind, but in the meantime, it would be really nice to ride the board I just built.
Thanks in advance!
