Hi

I have one question how i need to wire my switch (water )   to   cs-mio   and i would like to stop water when my cnc go on my auto length tool  and active water when it quit my auto length tool  ?

Can you help me .

Thanks

By water I presume you mean coolant? How is your coolant actually switched, is it a solenoid valve? If it is you will likely need a relay as the current draw of a solenoid will likely be more than the CSMIO can handle (250mA if I recall)

Not sure what you mean about tool length and switching coolant etc. Coolant is normally switched on by M8 and off by M9, so if thats in your code it will do it.

yes it is a solenoid valve 120Vac 4w   ... 

You will need a suitable relay with a 24v coil, you can then switch the solenoid with 110vac from the contacts of the relay.

hi
you tell me  that i need to add a  M8 to my g-code ...but i use Artcam to generate a g-code ... can it do this automatically

Never used ArtCAM but most CAM packages can do it, whether that is from within the CAM itself or by Post Processor.
Failing that you could add it to the script for the M6

i changed my post processor in Art cam

M6


Now which script of button i need to change  ...do modify  the procedure of M6   ..... Now i just have yellow led flashing and message : Press CycleStart
I not see the button tool change on mach3 i see just auto tool zero .... i think M6 is not for auto tool zero button

It will depend on exactly what you want to do but likely you will want to modify your M6start macro to include the tool setting script. You will also need to change the option in General Config to Auto Toolchanger so that the M6 macro will be used.
