Hi Aiph5u,
I am not sure you are actually using this controller, because otherwise you might have noticed that all sounds good on paper, but in practical application the buildbotics controller is just a little better than garbage, is full of software bugs.
What I encounter on a regular is:
-Program loading over wifi fine initially, after cutting a few toolpath the upload will not work
-Lost steps because the Rasperry Pi cannot handle the amount of data, resulting in random cutting and loss of workpiece
-Controller does not recognize memory card
-Controller does not recognize Joypad
-Controller does not home one axis after start.
-Controller loses machine home resulting in running into the limits of the machine bed resulting in motor stall and consequently loss of work home.
-Numerous other bugs that do not come to my mind right now but require restarting.
-controller bugging when you hit stop followed by any other button while stop is still flashing yellow like author of this post encoutered.
It is so bad that on any day I start the controller there is a at least 50% chance of having to restart at some point. Often I have to restart multiple times.
Add to that the fact that restart, machine homing followed by workpiece homing takes several minutes, the amount of time I lose is considerable.
This forum is full of post of people having to restart and loosing their work home, resulting in loss of the workpiece.
