Hi everyone,
Well I have completed the 4 axis BOB Board and tested it. Pics have been taken. I have nearly completed one of the Single Sided 3977 Boards & have been inspecting the soldering with a magnifing glass and multimeter very reguarly (my eyes are no longer as they used to be.
Question: I have read the warnings about not disconnecting the stepper motor while the Power is on, But can you test the board without the motor connected?
As I have only the final stage of testing to go before soldering in the 3977 (I am dreading the even thought of that) I really need an answer to this one. I only have 3 chips and don't know if I can obtain any more, so am being very careful.
Thanks in advance.
