If I change the x values and chase the thread on a piece of 3/4 stock it works great.
When I change to 3/8 stock I keep the draw back on x to 100 above stock the threads
look like ski slopes lol?
one side of thread looks like 30 degree the other side looks like 60 degree from center out.
What am I doing wrong. Just got this machine in off of ebay lol ... HELP! Thanks
