Marlin: Tevo Tornado not making Marlin Firmware open source

[uwuscutely]

The Tevo Tornado is using a Marlin Firmware however they are not making it open source. That is considered violating the open source law of Marlin. Any solutions?

[Roxy-3D]

The first step is make a formal request that they provide the current (shipping) source to their customers.

Someone has already done so but the CEO declined

maybe a few emails from the marlin Dev team could clear this up, its striking a startup like Tevo would do this. "kimhee you have the email addr. spare a willing Dev from having to search for it"
did the printer come with an Sd card ? is it on there.

It did come with an SD card however it's not in there

They have released the firmware. Right now it is posted in their facebook group under the files section.

Can you provide a link? I was trying to check it out and I can't find the 'Files' section.

The firmware can be downloaded here but you will need to join the TEVO Tornado Owners group: https://www.facebook.com/groups/TEVO.Tornado.Owners/274134936426057/

That's better. Under GPL a vendor cannot require you to sign up for a group or attach extra conditions to obtain the firmware.
