Re: Hardware temperature control tsdz2

More and more different solutions are being offered to improve the heat dissipation of the tsdz2. RicMcK has packed the laminated core of the motor with aluminum, combined with high-quality thermal pads and compound for better contact. RickMcK indicates that the temperature is now almost the same bo...

If you setup 48V for a 36V motor and keep the power low as for 36V, the current will be lower with lesser ch...

The cgq8 is the speed sensor with a double head connection for lights.
In that case it looks indeed only a different controller with bluetooth with the same motor.
This has consequenses for installing (and developing) OSF.

Pretty sure l used the firmware from the github that stancoke had a link to page 14 l think. I'm away for a few days so will check when l return and update of required.
The github version of stancecoke is indeed the 19C version too. Inside the files, the date is: 31/7/2019

I'm using the V19 and 3.7. ........
v. 19C is the latest.
Version 19A and B has this stil this bug.
So, if you want to prevent the same problem, check thoroughly if you have the "C" version of the firmware.
The java-configurator v3.7 is the same for all.
