How to use probing in Mach3 || Tool length offset sensor

[@MSM5500]

Thanks mate!. You're probably the only adequate person on KZbin who uses Z zeroing touch sensor properly. The other freaks all over the place are obsessed with use of the silly "touch plate thickness" parameter whereas we only need to know a delta between the tip of the initial either tool or probe (whatever hits the stock Z0 datum first) and all the offsets of every next tool used in the machining sequence.

Good video, but as you pointed out the machine bed and the spindle are earthed, so you don't need to attach the probe earth lead to the machine, just clip the hot wire onto the plate or tool length probe and off you go. And as you have gone to the trouble of isolating the tool length probe, you could leave that permanently wired, which means you only have to connect up the touch plate... this can now have a permanent connection so no messing around with crocodile clips and no possibility of forgetting to connect it. (just cont leave it anywhere that it can trigger the probing input.) :-) I use VB scripts capture x and y per job I take z as being the machine bed in CAM so I don't run into the issue of wanting to use a datum that I just milled away. That said i tend to mill mostly wood - so a piece of stock that 1/2 a mm thicker than it should be does not cause a problem, ali...not so much. this approach helps minimise the chance of the live tool coming into contact with the the bed or fixture.

Great video helped me a lot and I have watched a lot that didn’t help at all…Thanks

[@NerdInventor]

Nice! That is some high detail!

[@Uniquelymade]

Yeah I tried to compress it down but there is a lot to cover

[@mandem9319]

You did an amazing job with going through all things necessary man! Thanks a bunch also, since I'm about to reach the point of setting this up on my own DIY CNC machine :-) Cheers and keep up the good work!

[@Uniquelymade]

Thank you! I really tried to get out to like a teen minutes video but there was kinda a lot to cover. I guess with a script and less rambling that would have worked ^^

[@pawel102]

​@@UniquelymadeHi, I used your script but I have a problem. I set the zero tool, zeroed the surface of the processed material, then went to zero tool setter. when changing the tool and zeroing, the tool ends up with a value of approximately +220,000 and so on with each another tool. Can you help?

[@mangeh9520]

Great video! Could you do one with what youve learned from building your CNC and do differently if you would do it again? I'm also intressted in the end or current cost of this project.

[@Uniquelymade]

Thank you! That's a great idea. I just moved tho and don't have my machine here yet but I will put it on the video idea list :)

[@tontonsatan3093]

Interesting video and well detailed. However...Tried that probing wizard and the version might be different from yours, on mine the z height probing returns stupid values (like -8952...) and is overall really crappy buggy shit, which version did you use? Or maybe it has to do with the mach 3 version you're using(using the latest personnally) Same goes for the auto tool zero script you linked, after probing the z axis wants to go down crashing in the probe instead of going to safe z, lol... Other than that, keep up the good work, you craft nice things.

[@ArcAiN6]

so, i have a 4-pin touch off probe with over travel alarm (two pins for probe, and two for over travel) How did you set your probe up in mach3? i see a ton of options in the configuration window, but they are all named, and none are touch off probes or whatever

[@DangerFreakTV]

Awesome !

[@MrScary-zu1vc]

I got Probe wizzard that you use . I have problem with that . I don't know Why it dosen't work normaly . I try to find XY edge but it only move X axis it dosen't move Y axis . Do you know why ?

[@Yaroslav_Tselovanskyi]

So basically your first tool, the one you found zero with, will be the starting point, and all the other tools are just different Z offsets of the tool 0.

[@Uniquelymade]

Exactly

[@soorenaaslani7491]

So everything works great except for one thing. Before and after the tool change the M6 routines (M6start and M6end) slowly jog at 50mm/m to the X and Z machine 0. How do I increase this feed rate so it doesn't take an eternity? What kind of code do I edit in the files?

[@denniscolardo9773]

Hello may be you know how to make mach3 screen set to fit the screen? The mach3 sofware that the supplier gave me is very small

[@Uniquelymade]

I'm sorry, I never experimenters with custom screens

[@silelis1980]

Hello, I have question about 7m 11s of this tutorial. How do You change manually walues to: -10, -10, +7,95. How is it possible? I can not figure it out. When I press ctrc+z/ cltr+x/ ctrl+x I can write value but after enter it turns back to previous.

Hi nettes Video ich habe bereits den Werkzeuglaengensensor der funktioniert ähnlich eine kroko Klemme and die Spindel die andere fehlt dafür ist ein rundes isoliertes Teil dran auf das I fährt bis Kontakt dann 1mm zurück. Es ist am Breakout Board bei Probe angeschlossen und nun frage ich mich ob ich das auch für x und y nutzen könnte wenn ich ne kroko Klemme dazu mache bei schwarz. Wo ist deines angeschlossen?

[@Uniquelymade]

Meine x y und z sind alle am gleichen pin angeschlossen und schließen zu Erde

Hi Max, where can I find more info about the plastic z probe you have on your CNC and the script for it too. Thanks!

[@Uniquelymade]

hey sorry, I was inactive, I made that plastic probe myself

[@rolita85]

Salve I would need help to the wizard installation. After installation when active one of the probe functions the machine does not move the axes. Can help me solve the problem thanks

[@Andi-dx1hp]

Hello, I have the same problem, do you found a solution until now?

[@Uniquelymade]

Sorry the video is very old and I don’t even have the machine anymore

[@rengankrishnaiyer6912]

Sir, how the machine measure the top of the stock with respect to the touch probe ?

[@Uniquelymade]

It measures the difference in length of the tool

[@rengankrishnaiyer6912]

@@Uniquelymade noted, so how does it know the top of a material stock?

[@Uniquelymade]

I have a tool shown in the video that electically also probes that. The video is honestly very old and I don't even have the machine anymore

[@rengankrishnaiyer6912]

@@Uniquelymade thank you. I will figure it out

[@donatascivas1642]

When digitizing input is active, mach3 not allow move any axis, so whole machine stops right after touch happens..

[@Uniquelymade]

I have sold my machine and can't give any more support for this video, sorry

[@Inplacavel1234]

Did you ever get a error probe tripped during xy movement

[@Uniquelymade]

That probably means your motor cables are not shielded. You need to either move the probe cable away from them are get done optical isolation on the probe cable / some filtering

[@Uniquelymade]

The current in the motor cables induces a voltage spike in the probe cable

[@Inplacavel1234]

@@Uniquelymade thank you for the input ,I've tryed a new cable that's completely outside the machine and i still have the same problem

[@Uniquelymade]

What's your setup? What controller are you using?

@@Uniquelymade I have the problem in Z touch. If I start the Z touch in the macro, it performs a quick touch and then a slow one, and then it gives the error. If I run the "tool height script", it runs without problems.
