So, Im starting a new project that uses 8 motors (all need to do the same task).
Does anyone know how many VESCs can be daisy chaned together as I cant seem to find any threads on how many can be used in unison or what problems can arise from using multiple together?
If the limit is the CAN ID number, it should be 256 devices (8bit coded), so you have some margin.
I believe if any fail in the chain - the ones past that controller will also lose signal/control. So you might want some form of redundant signal. I know Ben suggested against split servo control and only canbus for dual VESC 6, but i’ve run dual VESC 4.xx this way without issue, so besides cost savings 8 4.xx might be better (redundant) vs 8 VESC Six.
If you want to go all Six’s - i’d post up on his forum and see if he has any suggestions.
HTH - GL!
Thats some good advice there. The plan is to make a small plannetary engine using 8 planet gears, therefore 8 motors to run a beefed up gocart. Do you know of any resons a split servo shouldnt be used as wouldnt the input signal be the exact same for each vesc that way?
paging @trampa What are your thoughts on this as I see you posted in another thread about never using the Y splitters
Edit: Would it be possible to have multiple receivers connected to a single remote, so each motor/vesc combo can have a dedicated receiver… that way if one of the motors fail, it wont shut down the rest of the chain??
Using Y PPM slpitter on VESC 6 result in fried components.
There are more sensitive on VESC6 than VESC4, so if you never experienced trouble doing it with HW4.xx, ask @Nowind about HW6 
See the thread where we’re talking about it.
Multiple receivers can be connected to a single remote. For the small cost of the extra receivers I would think in this application that that would give you the best backup? There was a lot of discussion of the pros and cons on this thread.
Yes, Im using 4 receivers and 1 remote with the HKGT2B
Thats perfect news then.
Thanks for the help @BigBoyToys @bigben @Pimousse. next step is putting the DIY engine together 
Will there be a build thread here or somewhere? That will be great popcorn material! 
There definitely will be ( even though its not directly esk8 based )
and it all starts by me finally finishing building a £1.2k printer to make the large-ass gearbox for the motors ( pls save my wallet )
a quick update. The VESC 6 are still performing perfectly in whatever conditions. I got an eagle tree heavy duty and they barely go above 30°C in most of the cases. I’m running dual FOC 12S.
Just a quick update, I am waiting for my PCBs to arrive of my own version of the VESC6 , it is very similar to the original. Got all the components and reflow oven is waiting 
fingers crossed that all is going to work.
Looks like you might not be the only one waiting for their PCBs. These guys have even got their boxes ready!
Oh no 
Please Maytech, don’t sell more crap!
And they’ll have to fold it to fit in the box…
I don’t understand, I didn’t see Vedder release the PCB yet on vesc project, so how did you already order the PCB?
He released the schematics only, not the PCB. I have designed the PCB myself with Altium software. It took quite a while to do it in my spare time, but it is a hobby for me.
Cool stuff man I can’t wait to see what happens when you fire yours up. Please do share… really exciting times.
Would you consider releasing some readymade to the hungry hoardes here?
