I have a Robo 3D R1+ that I control with a Raspberry Pi. Everything was working great until about a week ago.
Now when I try to set up the printer for a print I will up-load the G-code (saved from simplify 3D). I will preheat the extruder and the bed. I will then extrude 10-50 mm of filiment to ensure the extruder is working and then I will start the print. At random times during the process I will get an error message to connect a printer via USB even though the printer was connected just a second ago. Sometimes I have been able to get the printer to go though the entire leveling process and then on the monitoring of the print it shows that the print is running even though the 3D printer is not doing anything.
I have done the following:
Turned off everything and let it sit for 10 min.
Turned on the printer and wait 10 min.
Plug in the Pi and wait 10 min.
Load astrobox and set up the print
I have also downloaded .11(22) and re-flashed my sd card with the software and it is still happening. If anyone has any ideas I would be great-full.
