what do you think is the next step? I already spent the time running programs in the air, marker test, wood test and metal test. I guess i need to redo the z axis stuff the right way. For test programs i ran the roadrunner small, the mudflap girl, biohazard sign, and a harley derby cover. I ran all of them in th eair a few times each to make sure the program was not acting funny. Then I ran them without z using the marker test. After that I moved to the wood blocks and then on to aluminum. I then finished up with some 1018CRS.
