Process of using professional tool setter is similar to auto zero. The first stage is to

seek tool setter with acceleration to G0 speed according to pre-defined direction.

When tool setter is triggered, the moving speed is decelerated to 0 and the

second stage starts. The second stage is to leaving the tool setter with

acceleration to predefined % of the G0 speed towards the opposite direction.

When tool setter changes its status, the difference between Z-axis coordinate and

predefined tool setter surface coordinate is used as the tool length offset and

save in tool library database. The movement decelerates to 0 then accelerates to

G0 speed to the coordinate where tool setting started. This process have

overshot when tool touches tool setter surface at first stage. Therefore, tool

setter with retreatable surface is required to avoid tool and/or machine damage.

A low cost tool setter has hard non-retreatable surface isolated from the machine

electrically. It doesn’t allowed overshot (or allows every small overshot), It

requires movement to stop immediately when the tool touch tool setter surface.

Setting process is to seek tool setter with acceleration to % of G0 speed according

to pre-defined direction. When tool touch the tool setter, movement stops within

1/1000s. The difference between Z-axis coordinate and predefined tool setter

surface coordinate is used as the tool length offset and save in tool library

database. Then machine accelerates to G0 speed to move the coordinate to

where tool setting started. Please pay attention, even with control system stops

within 1/1000s, the mechanical system may not stop fast enough to avoid tool

and/or machine damage. The % of G0 speed should be set small enough to avoid

such damage.

The tool setter input shares same input as the A-axis zero switch input. When

auto tool setting is used, A-axis auto zero can’t be used. Operate the main menu

“Config”->”Ports and Pins”. Click on page “Input Signals” shown below. The tool

setting is enabled by putting a green tick in the “OEM Trig #1” row’s “Enable”

column. “Port #”, “Pin Number” and “Active Low” should be set according to

physical connections (referring to chapter “Shape and Connections”, section
