TeaCup firmware

Hello.

Sorry for my English, I used Google Translate.

I have a homemade 3D printer with Teacup firmware and Raspberry with AstroBox.
AstroBox detect my printer, allows you to manually move the head, set the temperature, etc.
I’m trying to start printing, but as soon as the printer head is positioned at the origin of coordinates and make first move - the connection is dropped.
I tried to change the baud rate in TeaCup and Astrobox, tried different Arduino in printer, but the result is the same - does not work. What to do?

Thx.

Have you updated the software of your astrobox? There were some fixes in the latest. We also haven’t done any tests on teacup but maybe others here have.

Yes, of course, I’ve updated the program. Still it does not work.
