VECT Tool freezes after uploading lisp script

I uploaded a script to a MKS 75100 that turned out to be a permanent loop over the print method. Now VESC Tool completely freezes under Windows 10 after connecting to the controller via USB. It manages to read the hardware version, which is shown in the bottom bar, but that's it. I tried VESC express, but it is unable to establish a CAN connection too.

The auto-run checkbox was checked when uploading the script, so restarting the controller leads to the same state.

 

PPM throttle detected in Vesc Tool but has no effect on motor

I'm trying to setup a PPM throttle, input displayed in Vesc Tool but the motor doesn't respond. PPM Mapping and Input Setup Wizard show correct input values but after the wizard completes successfully the throttle has no effect. I made sure to click "Write Configuration to Vesc" and to write app config but no luck. I can control the motor with keyboard if "APP to Use" is set to "No App" but not when it's set to "PPM" or "UART and PPM".. I'm sure I'm missing something really silly but after many attempts I think i need help :) 

VESC BMS problem with LTO Battery

My electric supercharger project uses a 32s LTO battery driving a VESC 100/250.    I'm using an  ENNOID BMS which communicates to the VESC across the CAN bus.   If I check Vcell Min under BMS Limit Mode, the motor will not start.  I have Vcell min set to 2.2V and all the cells are well above that.     Is there a way to get this working?

Thanks

Steve

download logfiles (Express) via mobile?

What I am missing desperately: to be able to download logfiles (created with VESC Express) via mobile. Unfortunately, the VESC app (at least for iPhone) is lacking this.

Unless I am missing something, please PLEASE add this to the list!

Thank you.

Btw, if you want to replay / see details about your trips, upload them here (needs GPS data being included):

UART Servo Output Works in VESC‑Tool UI but Not via ROS Publish

Hello everyone,

I’m running a VESC 60 MK6 on firmware v6.xx with VESC‑Tool v2.05, connected over UART. In the App Settings → General tab, Enable Servo Output is set to True, and I can manually move the steering servo by sliding the control in the VESC‑Tool “Controls” view.

However, when I publish a Float64 message from ROS to /commands/servo/position,

(for example: rostopic pub /commands/servo/position std_msgs/Float64 "{data: 0.5}")

Connecting over USB with M1 Macs

Hey Team, I have a Go-Foc G300 and Flipsky 75200 Pro V2 and both will connect to the vesc app over bluetooth on my m1 mac but not over usb, I have tried with a 2013 macbook with intel chip to connect over usb and it connects perfectly. I have tried to search the forums for an answer but haven't come up with anything, does anyone have any insight please?

Thank you very much.

Ben
