Bridgeport/Romi EZ Path 2 SD
Need Help. We have a 1999 Brideport Romi lathe that we are having threading issues with. Below is a link to a video of it. It mainly does it on course threads such as 2 or courser. It does not do it everytime. It will also jump in the middle of a thread. The z axis and spindle encoders are good. Does anyone else have this trouble or know what my problem is. Thanks

A coarse feed rate and enough rpm will force this to happen. The general rule of thumb is 2 threads out in front is the best start position to synch with the tach. In the case of a left hand thread you will have to run the spindle slow enough so that the thread cycle can make the tool dive in at the start of the left hand thread.
Every CNC lathe has a feedrate limitation in the threading cycle and the EZ Path is no exception. When you have a very coarse feed rate as the videos show it's not unusual to see this sort of jumping. Slow the rpm down and start the spindle before the thread cycle is enabled.
