I've had my 10EE a little over a month, no problem until today. Wanted to cut some threads as I have done on this machine several times before without incident. Set up everything for threading. The lead screw would not turn. Called the factory. Very helpful pleasant people to deal with. The guy told me to take the cover off the change gears to make sure all gears were engaging. Did that all gears are engaging. He told me to call back tomorrow and talk to Scott who is more expert in the gear train. I can turn the lead screw easily by hand but it will not engage mechanically. Any thoughts?
