Everytime I drain the water from the bathtub upstairs the bathroom
sink in the basement starts to badly overflow. But I could leave water running in basement sink and it drains O.K. I snaked out the main drain and it still backs up out the sink after taking Bath. It does not back up through main floor drain at all. Need help with this one.

Run the snake the opposite direction. You are now running to towards the street. Run it towards the pipe coming from the upstairs.
When you opened the cleanout plug, was it full of water? If not, the blockage was from that point back and not from that point to the street.
Most people assume it is from where ever they are to the street so they miss this type of problem.
Alternatively, you could take off some pipes and go from there down. Perhaps from the bathtub trap down. Perhaps from the bathroom sink down.

it sounds like the tub downstairs ties into the drain line before the basement sink does, and that there is a blockage in between the sink and the tub. pull the trap on your unpstairs sink, or pull the toilet upstairs and snake the line from there.

You have a ventilation problem, not a clogged drain. You need to check your vents on your roof and make sure they are not clogged or blocked.

Snake out your sanitary vent since you have the machine.
