Do you have a source for “normal guidelines” I can review w/ my students?
Background, we got CAN errors at the end of the daisy chain on this year’s robot, but didn’t have time to troubleshoot beyond “swapped the physical device, it works now go” at SVR.
We ran twelve devices on the bus this year, mostly physically located directly off the PDP (for minimum power wire length to each Talon). The preattached CAN wires were extremely too long, so after we soldered the adjacent devices, we bundled them up and tucked them underneath the power leads. It’s physically beautiful and preserves cable length for future years, but in retrospect added a fat inductance loop between each device. The final device on the daisy chain (Talon controlling an intake arm) got the intermittent control errors.
Would those inductance loops be contributing to this? Or do I need to look elsewhere?
Sweet! The drive rectangle turned out especially well, I really like the packaging you found. Do you have any provision to spring-load it similar to 2767’s positraction?
