Noob question thread! 2020_Summer

Stupid question… I can’t seem to figure out how to connect vesc tool on my windows laptop to stormcore. I can pair the bluetooth but stormcore doesn’t show up in the tool

Use this vesc tool. Bluetooth works on Windows with this one.

Don’t connect the esc directly to the computer.
Go to the vesc tool connection tab > bluetooth le > press the scan button > select your esc > connect.

Thanks confirming official version of vesc tool doesn’t work with bluetooth?
Seem kinda a silly bug.

AFAIK, vesc tool 3.0 (fw5.2) has buggy BT

Worked like a charm. Much appreciated

Veteran materials specialists: 18-8 stainless for truck bolts, yay or nay? Just double checking that I haven’t been tempting death :joy:

Truck bolts you’re definitely going to want zinc alloy steel. That’s the most important structural/load bearing fastener on the board.

Stainless is not ideal for the job

Thanks! Like these guys? McMaster-Carr

Yeah, I’d personally go for 10.9 steel (instead of 12.7) with the idea being they’d bend before snapping but only matters when there’s a car on top of your board.

What are you guys’ opinion on using heel straps on mountainboards? I’ve been looking at some trick videos on YouTube of mountainboarders, and the mobility you get without heel straps look quite appealing, and they’re still able to stand perfectly on the boards. And they don’t drag their boards with them every time they bail.
The question is though, would it be a good idea to use/not use heel straps while offroading in forests and driving on mountainbike tracks?
There’s a lot of vibration in the forest, so maybe that’s the main reason to use heel straps in this situation?

Btw check this insane trick at 2:30 !

Ok, so just setting up my new stormcore. I noticed in setup that the “slow ABS Current limit” is set to false whereas when i previously setup my flipsky vesc it was set to True. Can someone explain this setting for me?

Thanks heaps

also, noticed the “Duty Cycle current limit start” is set to 85% instead of previous 100%. Not sure if I should be concerned

85% is safe. 100% wants you to die

Thankyou.
I have another issue now. My Flipsky VX2 remote is pairing to the receiver but the motors are not responding to the remote. My motors are working as per the setup test but the remote is not able to control the motors. I have traced the wires to the receiver and discovered i needed to swap tx with rx. This is now done but still have the same problem. Here’s a screenshot of my remote settings in vesc tool, remote setup on the remote itself appears correct (i’m assuming stormcore is still fsesc or do i need to change to focbox?)

Starting with the easiest rather than most likely:

Do you have a pic of the UART connector where you swapped the TX and RX? The connectors have a different number of pins, so it’s possible to connect it shifted over by one pin even after you swap the TX/RX

After that, bit of background. The stormcore is designed by the same primary engineer as the Foxbox Unity, and has a lot of similarities even though it’s a significantly upgraded next generation. I’m trying to dig up the useful threads on VX2s and unities, it’s a common issue getting them set up.

I did get mine running properly on a unity but struggling to remember what fixed it. I think it was a combination of

  1. Not having other UART devices, plugged in including the unity’s BT module
  2. Toggling/finding which one worked between FSESC and FOCBOX in the VX2
  3. Swearing

Actually I’m fairly sure it was this, the UART thing only caused problems with telemetry not with basic functioning:

Thanks so much, this worked! I now move on to my next problem(s):

1 - The VX2 is not picking up the speed and displaying it on the remote (i assumed this would still work with the Stormcore…)
2 - It’s hard for me to say for sure but i am 90% sure the speed setting on the remote is making no different (the reason i’m not 100% sure is because my deck is in the mail so running this by hold my rear truck up whilst I test, but i’m pretty sure i should be able to notice the difference between low speed and high speed)

Ayyyy nice. So again, easiest first: your throttle doesn’t control speed, it controls power, like in a car. Sure if you want it to go more fast it needs more throttle, but it very much depends on the driving conditions and you can’t compare throttle position vs speed under different conditions. 50% throttle on a board is a very different died when there’s a 40kg kid vs a 100kg me on it. Because it takes very little power to free spin the wheels (even gripping with hand strength for resistance), you’re not gonna notice a huge difference between power modes. Ride with a person on it, if you still don’t notice a difference then there might be an issue.

Speed display: this is the telemetry issue I mentioned. For me it was one or both of:

  1. Extra UART devices confused the unity + VX2 combo
  2. VX2 expected telemetry data in a particular format, and whichever Foxbox/FSESC setting I set it on was wrong.

I haven’t got a super clean answer, but I would give good odds that just switching up the remote “ESC mode” and/or making sure there aren’t other UART devices will fix it. And I’m 99.9% sure changing these will not bring back your earlier problem of not driving the wheels, that was almost definitely caused by the “Control Type” input setting

Thanks, I think you are right

listening carefully when I have the thumb wheel ever so slightly pushed forward I think there is a difference so I’ll park that as a non-issue.
On the other issue I have tried switching the esc mode on the remote but doesn’t change anything.
Given the app settings were wrong for control type, do you think there are any other settings I could try?
Worst case scenario, when my flipshite esc toasted it did some damage to the receiver which is stopping the telemetry coming back to the remote

IMO it’s very unlikely that the receiver is partly damaged, UART being the relatively complicated digital interface that it is it either all works or is all dead. The reason for it not to be displayed is not so much that the receiver isn’t sending it, but that the remote isn’t set up right to display it

One troubleshooting tip that could help though: whenever you make a change to the remote settings, turn both the board and the remote off and back on again. The initialisation routine solves a lot of problems. Should have mentioned this earlier because I tore my hair out when I found it, but it’s been a while since I messed with a VX2 so I’m fuzzy on the details

I have lower confidence in this, so feel free to go against it or take correction from others: I don’t think there are many (really any) settings of substance in VESC tool for UART that help with this stuff. It’s basically just “is it on” and “did you turn on control input in the VESC remote section”.

Thanks for the tip, tried again and still same problem, even tried repairing to see if somehow that made a difference.

I will mess around a little bit more but if anyone else has any ideas that would be great.

Thanks again, I am miles ahead of where I was, at least now I can use the board!
