I own a L28 cnc machine (TopTech-Optimum) with 808D control. When threading a " wait for first thread cut" line appears. We take a lot of care programming the thread code, using cycle 99 or g33 same problem arises. I bought the machine 30 days ago and is a new machine.
There is only one rotary encoder mounted on spindle and the right ratio is operating.(300 up to 3000 rpm) k9 funtion. With other turning operation things seem to be OK. Thank for you advice.
By the way ¡Happy New Year for all of You!
