- CNC Machine Workpiece Zero: How to Set it Perfectly Every Time!
In this comprehensive tutorial, we dive deep into the crucial process of setting the workpiece zero on a CNC machine (here a CNC Router). Whether you're a beginner or an experienced machinist, mastering this skill is essential for achieving precision and efficiency in your machining projects.
In this video, we will cover:
- The Machine and Work coordinate system
- Step-by-step instructions on how to set workpiece zero manually
- Tips and tricks for ensuring consistency and avoiding common mistakes.
- The different Tools and techniques to help you achieve perfect results every time.
- My Prototype set up that uses a vision system to set X Y Zero
By the end of this video, you'll have the knowledge and confidence to set your workpiece zero like a pro, ensuring top-notch results in your CNC projects. Don't forget to leave me a like, if you got value from my contend - I would really appreciate it!

welcome back! have missed your videos if you have time you could make a tutorial on Eding cnc software, all the ones I've seen are in German.
Thank you for your valuable tutorials. Is the Eding software completely free and is it compatible with grbl?
The software license is included when you purchase the controller from Eding. You will no longer need GRBL.
Thanks for taking the time to put these videos together - they're very helpful! I picked up the normally open version of the 3d tester after your previous review and I love it. I've got it in a dedicated tool holder for an ATC spindle so that I can use it to probe x, y, and z. It has made multi-tool jobs a lot more pleasant!
That’s the way to do it. It makes much more sense in an ATC. 👍
I've really been missing your vids! Hope you have some motivation to post more of them in the future :)
I hope so too 😀😀
Welcome back 🙃 Now back to my Plasma Table build ......
Good luck for your build!
Hi, nice to see that this kind of 3d touch probe is also available as "npn-nc" as well........ usually (99,9%) of these are "npn-no". Unfortuntelly PGFUN does no send to Germany.
Oh I did not know that. So it’s not available on the German Amazon ?
@@JBWorx Yes, correct. When I click on your link, Amazon says "This item cannot be shipped to your selected delivery location. Please choose a different delivery location."
@gebbi80 so I looked on Amazon.de. I found the probe also as NPN but they are the NO contact version. If you cannot get the NC version I think it’s not the end of the world.
Hi @JBWorxStudio
Thank you so much for the valuable content and information on this channel.
Having recently moved to Eding CNC, I would love some more content on setup and use of this CNC software.
So far I’ve only come across one German youtube channel, M5 by Michael Heyder, that explaines a bit about this software. Not being fluent in German makes it a bit difficult to follow this information.
Hey that is super awesome that you are using Eding CNC as well. Yes I know his channel - he has an accent as well so yes not as easy to understand. I will note down to make a set up video on Eding.
@@JBWorx Please do!
There are not many english tutorials, but plain basic ones, explaining Eding CNC, so I guess it would cater to english speaking users of this CNC software.
And there are so many nice features within this software
Agreed I was always happy with this software also if you ever need a repair on your board you can send it in and get it repaired or replaced for a flat fee. Pretty good service.
Sir, how do i know the top of a part if my machins is probing using a tool length sensor placed on my cnc table ? Do i have to premeasure its thickness first and enter somewhere in the probing function ? I have use a fixed thickness touch probe placed on top of a part and probed it. The probing macro knows the thickness of the probe hence it can 0 correctly above the part. Just that i don't understand how it can predict the top of a part if it is probing on a TLS placed on the table.
You will probe twice. First on the calibrated standard position on your table. This will tell the controller the length of the tool. Next you probe on top of the part. This will tell the controller where the z zero of the part is. Now for the next tool change you only need to measure on the standard position on the table. The controller calculates the offset from tool one to tool two. Hope this makes sense.
@@JBWorx thank you for the reply. looks like your probing macro/function quite advance. I am using mach3 and macro I hv can be used to probe using touch plate. from probing I will hv the Z 0 of top of part. maybe you can do a video to demo wow do u probe with TLP?
Very nice review of setting coordinates. Thanks
Thx for reaching out !!!
It's nice to see you again, great as always !
Thank you for reaching out !!
excellent video sir
Thank you glad you liked it
Welcome back!
Thx trying to post more in the next couple month
Das mit der Kamera finde ich interessant. Nicht unbedingt zum edge finding, dafür ist es mir zu viel guesswork. Aber da könnte man evtl. selbst mit Eding so eine Art Steuerung wie bei Datron aufbauen, wo mit der Kamera die Bereiche gekennzeichnet werden, die der Taster anfährt. Letztes Jahr waren beim open house day von Eding ein paar Jungs da, die da eine vielversprechende Demo gezeigt hatten...
Gibt aber imho zwei Dinge zu lösen. 1. Haltbarkeit der Kamera. Ich hatte mal einen ausfahrbaren 3D Finder an der Z-Achse und den haben die Schwingungen gekillt. Ne HD Webcam hat keine beweglichen Teile, könnte daher vermutlich auch dauerhaft klappen. 2. Sauberhalten der Linse. Meine Z-Achse ist an der Unterseite ziemlich verschmandet, mit einer fiesen Mischung aus KSS der MQL und feinsten Aluspänchen vom Gewindewirbeln. Da müßte die Linse irgendwie vor geschützt werden, mit einer Klappe, o.ä...
Fänd ich klasse, wenn du in der Richtung etwas experimentieren würdest 👍
Ja ich hab ein USB Microscope mit einem Schutz (einfach nur ein Plastik Aufsatz vor der Linse) welches etwas weiter oben angebracht werden kann. Ich denke für Projekte wo man eh außen die komplette Kontur fräst ist das sehr interessant. Danke für dein Input - hatte einen pneumatic cylinder vorgesehen um die 3D Probe anzubringen (a la Datron schwingt also von oben runter im Halbkreis) … ist dann aber wohl nicht so eine gute Idee wenn deiner das nicht ausgehalten hat.
Danke für dein Input.
@@JBWorx Ich hab da auf Insta mal einen etwas detaillierteren Post zu gemacht. Sowohl zur Mechanik des Ein- und Ausfahrens, als dann später auch zum Fail 👍
Oh ja sehr schön dein Equipment!!
@@JBWorx Danke dir 🙏
Nice stuff English too. !
6:30 If your spindle is electrically isolated from the bed, it's really helpful to wire up an LED so it will light up when the tool makes contact. More precise and won't leave a mark on the workpiece like homing by feel. The same electrical conduction can be used for auto probing too. Obviously it also requires a conductive workpiece, though at least for Z probing, you can hold a piece of aluminum foil on top of the workpiece and touching the bed and probe to that for a reasonably repeatable position.
Yes that is a good suggestion. I also like the aluminum foil tape and just wrap the edge of the part if it is not conductive. However I stopped using this method after breaking a really expensive Datron bit. I set Z with my tool length sensor and use the 3D probe for x-y. It is accurate and fast.
