I was looking at purchasing a Weco Formtracer FT3-D+ as a back up tracer but on try out it and first turning on in the morning it shows a trouble code "TMO stylus up" and the stylus does not go high enough to enter the frame . After several resets the stylus goes higher after each reset then eventually operates normally for the rest of the day until you turn it off and start over the next day .


Any thoughts as to what causes this ? The accuracy is perfect. It is like the stylus is sticky but yet that is not the case , when operated by hand there is no impairment of movement.
