Command meanings: (Semi colons separate command sets)
G38.2 Z-25 F100
G38.2 is a probe command which means, seek until the probe circuit is closed (Arduino ground to
pin A5). Z-25 means drop the Z axis down a maximum of 25mm (metric in this case). Of course, this
travel should be interrupted by probe contacting the plate surface. F100 is the probe travel speed.
You may want to slow yours down, but 100 works fine.
G91 G0 Z3
G91 G0 Is a rapid move, the Z axis 3mm up or positive direction.
G91 G0 X-50
Then rapid move 50mm left, or negative X direction.
G91 G0 Z-8.2
And drop Z down 8.2mm in preparation for X probing.
G38.2 X25 F100
Now probe for X side of the calibration plate.
G91 G0 X-3
Pull bit away from the cal plate 3mm.
G91 G0 Z8.2
Raise bit up 8.2mm before moving to the front of the plate
G91 G0 Y-50
Move toward front of the plate 50mm.
G91 G0 X50
Move right, in the X positive direction, 50mm.
G91 G0 Z-8.2
Drop the bit back down 8.2mm in preparation for Y probing.
G38.2 Y25 F100
Probe Y axis.
G91 G0 Y-3
Pull forward off work, 3mm
G91 G0 Z8.2
Raise bit 8.2mm.
G10 P0 L20 X? Y? Z?

Great video, thank you, helped make my MPCNC a lot easier to use
Great video, this music is depressing AF though.
Thanks a lot! Very good video
Nice work! 👏🏻👏🏻👏🏻
love the video editing
i have a problem, g38.2 give me error code. my mach3 no recognize g38.2
one concern I see with your example is if you happen to touch off on one side with the cutting edge of the carbide and the body of the cutter on the other side the offsets will be off.
I was about to say same till I saw your post
Hello Nice video. This should help me since I am new to CNC. I have a fully nested CNC with Rich Auto B58e controller. When editing my post, where should i input these lines of code. I know i'll have to tune the # to my probe. My machine uses standard g-code G21. Any help is greatly appreciated.
hello
if he/it pleases you the software that it uses is Mach3 or another if yes which
Hi. What software can do xyz probe ?
salut tu as rien brancher a ta carte de pilotage ?
Hi!
Your video is very good.
I was calibrating the height of my cnc with a homemade sensor.
The height of Z is already fine, but now it doesn't move for X :(
Could you help me please.
Hello! Can you tell me where you connected the XYZ-Sensor cables. You have a wiring diagram or a video that explains it, especially the connection to the CNC Shield. I will thank you for helping me connect the sensor. Thank you.👍
You need to get a wiring diagram of your CNC controller, I'll try to find it at WEIHONG NC Studio here.
cut the cable on your router or undo the coil , youre going to have a fire not to mention creating EMF
Great
I don't have a problem doing the piece entirely of aluminum. It will be more precise, and will last longer.
Why not just use a square sheet of metal with two flanges bent at 90º?
Tengo una cnc y necesito ayuda para calibrar
นาทีที่6:02ขึ้น ที่มันวัดระยะเอง นี้โมดิฟายเพิ่ม หรือมันมีในโปรเกมอยู่เเล้วครับ แล้วท่าทำเองยากไหมครับให้มันวัดระยะเอง
Good work but can i know from what you get x=35. 943 and the y=-17.255 please explain it thnx again
Please check this video, calculator is available

...I like the “clearance hole” best...
... oops, I forgot to remove the probe and it dives at X0 Y0...
SWEEEEEEET!
Nice video but yes when using x and y probe you should use a dowel or anything perfectly round not an endmill..an endmill wont give proper zero..so it in reality cant be done accurately with an endmill..for x and y.....
Maybe you could always spin the endmill so that the cutting edge is not touching the work edge ?
@@pentachronic Its the cutting edge that NEEDS to touch the device
@@Mogul25Years Actually it is the center shaft that needs to touch. As long as you know the diameter of the center and it consistently touches off on the center. The problem with using the edge is that the mill can rotate and become an eccentric reference. This is what I was alluding to.
I have a couple questions:
1) Have you tried using it with the built-in probe module in UGS? It seems like it should work.
2) Did you build it with materials you had handy? I'd be a little concerned about the wood (looked like MDF?) expanding over time due to humidity. If your machine isn't capable of cutting aluminum, you could use something a little more stable but very easy to machine like Delrin.
In any case, that was still a very interesting project and gives me some ideas how I could create my own since I am still using the Z-only "puck" type.
I use this code, tune it to my mdf thickness...its actually from Ryan of Ooznest. I have not tried the UGS inbuilt.
thick aluminium and delrin or HDPE is difficult yo find here.....and yes MDF is not the best for long term use...............
@@MickyRalte Either way, that's a cool project. If all you have is MDF, you can use a sealer to help protect it from expanding. We have a big ShopBot with an in-house built vacuum table and middle layer of the table with the vacuum channels is made from MDF. I believe we used shellac but any kind of sealer would work.
Ok I know my probe is cheap but that thing is thuglife cheap lol
