The Haas VF4 (sometimes called a VF-4) is a popular medium size CNC, with a travel 50 x 20 x 25. The programmed value must be half the total tolerance.Used Haas VF4 For Sale Medium Size Haas CNC VF4 The tool length error exceeds the programmed Mm tolerance. Check that the probe stylus has been calibrated on the machine. Check that the status LED on the interface is changing state when the stylus is deflected. If this does not happen, contact the supplier of the system for assistance. The expected surface is not contacted within the overtravel of the probe.Ĭheck the program and edit where necessary. A program dwell may be required. Check that the status LED on the interface is changing state when the stylus is deflected. If this does not happen, contact the supplier of the system for assistance. Check that the stylus is not in contact with the surface or check to see whether vibration is causing it to unseat during a move. The alarm may also be raised at the start of a macro if the probe system is in error (a probe open signal condition is forced by the Renishaw interface). Check to make sure that the probe system is switched on in time before a skip move begins. If the stylus remains in an open (triggered) condition during any part of the cycle, the PROBE OPEN alarm is raised. Return to reference and edit the part program. The stylus is in contact with the surface before the skip move begins. Refer to the macro programming section of the Renishaw Manual for the relevant inputs required.

Caution: Make sure the turret is safely away from the probe stylus before indexing the turret. If using the ‘T’ input on the cycle call line check the value is not zero (0), otherwise this alarm may occur if no tool or tool offset was selected in the MDI mode before running the cycle.
