Connecting Multiple ESCs: Dos, Donts and Dual Receivers (SERIOUS)

[b264]

Yes

@b264

Assuming you have skate A and skate B and they each have VESC-compatible ESCs Left and Right

(this actually won’t work on single drives ) (assuming dual drive for everything)

​

• Connect a Mini Remote radio receiver to skate A ESC left
• Connect a Mini Remote radio receiver to skate B ESC left. (You could actually do this with more skates, but only with 2 remotes.)
• Connect a GT2B radio receiver to skate A ESC right
• Connect a GT2B radio receiver to skate B ESC right.
• Pick two integers, I’ll use these two. They can’t be the same. left: 37 right: 42
• Connect a bluetooth or metr module to at least one ESC per skate.
• Grab a paint marker and write “37” on a Mini Remote. Write “42” on the GT2B remote.
• Power up and pair all receivers, and set the failsafes , and set the throttle mapping and curves on every single ESC. They all need to be set.
• Connect to the bluetooth or metr with a mobile handset (with wifi connected) using VESC-Tool or metr smartphone application. Turn on TCP forwarding.
• On a laptop or desktop on the same wifi (or wired) network, connect to VESC-Tool and set all the left ESCs VESC ID to 37. Set all the right ESCs VESC ID to 42. This is in App_Settings > General . Write the changes each time.

to change remotes

• Connect to the skate with VESC-Tool using a forwarded TCP connection
• In App_Settings > PPM > General change both ESCs’ Multiple VESCs Over CAN setting to False and write the value. Don’t try to get ahead of yourself. Turn them both off FIRST . ignoring this can cause you to have to open the enclosure and use a USB port
• Now look at the remote in your hand, and whichever number is written on it, go to that ESC on the CANBUS, and set Multiple VESCs Over CAN to True . Write the value. That skate is now using the remote in your hand and ignoring the other one.

So you can switch which remote is active in about 30 seconds…

Yes, to ensure that your canbus chips don’t die, both escs should be powered on at the same time.

Sooo… is it possible that I fry my CAN chip due to accidently lost power of one vesc caused by self-disconnecting the one plug from T-connector(split) while riding?

[glyphiks]

Depending on your esc and what can wires you had plugged in, I believe it is possible

Flipsky VX-1 pairs to multiple receivers, very unstable though do not waste time trying to run a VX-1 with dual receivers.
