This User's Guide has been compiled for tool setter Vers TS v.2.x currently manufactured. The  User's Guide for earlier releases is located here.

Purpose.

The Vers TS sensor is used to determine the exact coordinates of the tool (cutter) installed on a CNC milling machine by contact method. The CNC system generates these coordinates when the tool touchs the VersTS measurement platform and uses them to calculate the height and diameter of the tool, to link the machining program to the workpiece location. The device can be used with various CNC systems: LinuxCNC, Mach3, embedded systems on industrial machines, etc.

Specifications.

Installation.

   The VesrTS location is defined so that the entire surface of the ceramic pad of the device is in the working area of the machine.

The device is mounted in the T-slot of the desktop, if necessary, preliminary exposure of the measuring pad is performed parallel to the XY plane with a 2mm hex key from the kit:

Connection.

Be careful! Vers TS is an NPN-NC sensor, i.e. normally closed to ground. Connection to controllers with PNP inputs, i.e. designed for sensors short-circuited to power, it is possible only with the help of special npn-to-pnp Converter, otherwise, both the sensor and the controller may be damaged. 

The connection scheme for normally-closed npn sensors is applied, the color of the wires inside the cable corresponds to the colors of the connections  in the scheme. 

Adjustment.

Before starting the measurement, it is necessary to adjust the device. As a result of the adjustment, the surface of the measuring platform should become parallel to the XY plane. The control indicator is clamped into the spindle or fixed to the carriage of the Z axis.

   The indicator should be sensitive to a weak effect of 0.3-0.5N (for example, most lever indicators have this property).

First, the adjustment  along a line perpendicular to the axis of the device, then along the axis of the device.

Step 1. The approximate location of the control points for alignment along a line perpendicular to the axis of the instrument is marked in the figure. The control points are brought to the same level in Z by turning the adjusting screws M4 with a 2mm hex key from the kit. When adjusting, both tightening and loosening of the screws are used. The key is recommended to hold for a short lever, so as not to develop excessive force.

 Step 2. The approximate location of the control points for alignment along the line along the axis of the device are marked in the figure. The control points are brought to the same level in Z by turning the M2.5 adjusting screws (the screws are located inside the holes protected by rubber bands) with a 2 mm hex key from the kit. When adjusting, both tightening and loosening of the screws are used. The key is recommended to hold for a short lever, so as not to develop excessive force.

 It will take several cycles of Step 1 - Step 2 to achieve the minimum deviation acceptable for a particular measurement.

Using.

There is software ProbeScreen  in free access for convenient work with probe in the LinuxCNC(ver.2.6 and higher),

Probe Wizard - in the Mach3 system.
