    3. DO not working?

    I think I fixed it. In the BOM it gives the name of R1, R2, R3 as a 270 ohm resistor but a part number for 270k ohm. It should be 270 ohm. I switched out the resistors and the relays work now.

    3. Software crashes and robot shuts down

    I added the heat sink and that seems to help.  Heat sink gets too hot to touch, but no crashing.  Probably would be a good idea to add a heat sink to the BOM.

    The power supply is 3A, 36W output @ 12V. Nothing else is being powered by the power supply. Nothing extra on robot (end effector, tool). What is odd is when the servos reset to 90 degrees at reboo...

    Software closes, robot goes limp.  After 10 to 20 seconds the robot reboots and all servos quickly and simultaneously return to 90 degrees with no issues.  The LEDs remain lit.  My power supply is ...

    Thanks for the help and sorry for the slow response, I have been studying for the FE.  I made the file change and tested it on one servo and it seems to be working fine.  Moves and stays and also r...

    3. Software issues

    Hello everyone. Just finished my robot today and I am having the exact same issues as Pukindat JB.  Joints start at 0 and immediately return to 0 once J+ is no longer clicked.  I have not made any ...
