Hi guys this thread is a result of to much messing around and trying to get thing done the easy way, so anyway heres my problem, the machine was working fine with no problems until I decided to download big tex blue screen and set up an auto tool sensor. So everything was going fine but for some reason now when I send something to cut I goes in the opposite direction on the Z axis, I have been messing with the different configurations all day but I just cannot get it to work 100% when Ihit ref all the machine refs ok and then I send a toolpath the machine moves down the Z axis to about 50 and then starts going back up again and travelling to a -6. Any help would be great. Thanks again
