I installed a new hard drive on my computer and decided to install the latest version of SB. I had been using SB 3.5.18. I often use the keyboard commands to raise and lower the Z axis for bit changing. When using the page up or page down key with SB 3.5.18 the Z stops as soon as I release the key. With the new version the Z coasts to a stop. I don't like the coast, I want to have accurate control of where the Z stops.
Also, I typed JY 24 to move the spindle and decided to stop the movement by hitting the Spacebar. The movement stopped but I could still hear the Y motor. The software was locked up. I hit ESC to close but it wouldn't close. I used the Windows Task Manager to shut down the SB software.
These problems led to my uninstalling SB 3.6.36 and reinstalling SB 3.5.18 which has worked perfectly since I first installed it
