Hello, I have installed the latest version Version Mach4_Hobby 2.0.3206 and I used the Touch button.

After pressing the button, the motor starts running, the tool touches the touch plate but does not stop and the potential risk is to damage the tool.

I am using paralel port (Darwin plugin).

Can someone help me?

The touch button should bring up the TouchOff UI. Once you have UI up you need to make sure that if your probe goes active the blue LED lights up.

It is active, the problem is it doesn't stop and does not retract.
Am I doing something wrong?

Can you send a link with a short movie?

Question

Is it active when you open touch
Does it go blue when you press the tool setter or use a wire to mimic the tool

It should be black when you open the touch do da

Is the first small blue led on the front page on or off before you run the touch

Last on did it work before you installed 3206 if it did have you altered anything

Can you send a link with a short movie?

Keep an eye on this channel. I think some docs and a video will be coming in the very near future. https://www.youtube.com/channel/UCcZ847PqPXOUrksLYct-gaA
Until then, hoover over buttons, DROs, LEDs, etc in the dialog to see the tool tips when they pop up.

As Stuart said, make sure your selected probe input is working correctly.

Please have a look over the printscreen.

As you can see the Selected probe is currently active is blue.

An error appears: Unexpected probe touch. So I know I am missing something but I cannot figure it out.

Is it blue when your probe is not touching? You can use that led to make sure your probe is working as expected. On when touching off when its not.

If it is blue when touching and black when not touching but your getting an unexpected touch there is about a 90% chance you have noise triggering the probe input when it should not be.

It is blue when my probe is not touching.
Ok, so what shall I do in this case?

Check your setting

Look at the active low/high and change that
Is it wired correctly ?
Are the pull up resistors correct

With no probe contact the small square led should be black and the one in the touch should be black as wel the led in m4 diag should not be on

When the probe is active the above is reversed blue blue on

The Above needs sorting and proved before you even try under power

I had a a working system but the software had a glitch (now fixed ) I was using a 3D probe and it drove the tip through a piece of 12mm MDF
So I have had to sort a system out like you but with a ESS and m4 ,I cannot use a touch plate as the resistance though the machine is to high to get a good contact so I use a switch type tool setter ( wire I got is different )
Just waitin for Warp9 to get the G31.x sorted

Just go though the setting/wiring one step at a time and prove each change do not make more than one alteration at a time else you wil not know which one was at fault

Stuart

I'll let you know about these
