Wondering if anyone has attempted to convert their build into a 4wd setup by soldering the two wires from the CANBUS on one Flipsky 6.6 Dual VESC to a second one as seen in the pic below? Did it work?
The CANBUS on the 6.6 Plus version of the 6.6 Dual has a port for the wires but there are only two wires yet four pins on the PCB board. Anyone know what gives? (I am speaking about Flipsky Dual 6.6 VESC only)
This is from the 6.6 dual mini. 4wd is has itās own position on the switchā¦ looks like the CAN bus is used for 4wd and its 4 pin.
I did for a a few days just for fun.
It was 4wd 6374 with a 1:5 gearing on 8 inch tires
The front couldnāt get enough traction due to the slight wheelies it did from the back motors.
I instead went with bigger dual motors and cut the price substantially
SOflo - Yes, it is from the mini. It was the best image of the canbus switch that looks identical to mine on the 6.6 standard (not āplusā). I was using it to illustrate my question if anyone was able to connect the points specified and how were the 4wd resultsā¦
Still looking for input/results if anyone has any. Thanks!
Dirtbag - so it worked? You soldered the connections exactly as shown and the VESC did indeed drive the four motors no problem? No sparking ESC or anything, lol? Iām using 6354 motors. I have soldered wires to the points identified but I am nervous to apply power. Itās $600 worth of VESC thatās on the line here so I am hoping to get positive feedback before I take the leapā¦Was there any negative results from doing this? You just didnāt want 4wd?
@kchxaz you need to tag @Dirt_Bag to make sure he get a notification and can answer if soldering the CAN did work.
I run quad on other vescs and i donĀ“t use CAN to connect the vesc. I just bind a receiver to the front vesc and one receiver to the back vescs (each side is connected via CAN than). That will work with every vesc, also with your. you just donĀ“t have traction controll between 4 wheels, only between two wheels, but that is no big issue in my humble opinion.
I didnt even bother with that layout. I just used a ppm splitter cable and copied the settings on all 4 vescs. For perfect throttle matching, make sure you map the throttle identically on both.
DB - Iām probably over thinking this but what do you mean exactly to map the throttle identically? You mean the min/neutral/max wheel throttle position sensor? But youāve only got one receiver (since you have a cable splitter coming off your single receiver - one for each Dual VESC, correct?), so you wouldnāt have to perform the app wizard setup for throttle matching, right? Am I thinking about this the wrong way?
Program dual vescs as normal. Just match the ppm values on each vesc and your good.
Theres really nothing difficult about it, set up your first vesc and then do the second to match all the settings.
Will this work for 6wd?
That I cannot answer with confidence. Instinct tells me that you will need three dual VESCās if you want to approach a 6WD solution. Even then Iām not sure how you would wire the canbusās in that instance. If you havenāt bought your VESC(s) yet definitely go with the āplusā version that supports 4WD. When I bought my VESCās I asked Flipsky more than a few questions about VESCās being able to be used for 4WD solution and even with the back and forth questions the dumbass answering emails had no clue and I ended up buying the incorrect VESCās (my knowledge of VESCās then isnāt what it is now).
Speaking of Flipsky VESCās, yes they are cheaper than the competition but so are the devices - Cheap! Didnāt end up making a difference since one of the VESCās showed up DOA and when I tried contacting flipsky I was ignored. When the other VESC took a shit less than a month later and I finally did get someoneās attention they had the balls to charge me to fix the goddamn thing, including the one that was DOA. Never again will I buy Flipsky products of any kind.
Now that I remind myself of that catastrophic error in judgement, might want to avoid Flipsky VESCās all together. Just be sure that what you do buy supports 4WD connections. May I ask how this is going to be set up? Iām trying to picture a 6WD esk8 in my headā¦
