[@alanwood3597]

Hi Charlie, me again. I installed the edge finder scripts and these also work fine except if you accidentally leave the screen in machine coords. No matter which script you run it then causes a Y negative travel. Machine is a small CNCEST with RnR controller card. The scripts are quite useful for calibrating the X and Y movement. I bolted a 150mm parallel on the table in X and then Y and ran your scripts to find the edge of the parallel. After each script had finished I flipped to machine cords and noted the reading and then did the maths of the subtraction of the + and - readings and also subtracted twice the tool thickness. Having got an answer to the maths I fed this into the first calibration dialogue box where it asks for the distance wanted to move and then put 150mm into the second dialogue box to give the actual distance travelled. That probably is badly explained but I think you will get the gist. I did a similar routine on the Z using the tool height setter with and without a 1-2-3 block difference in height. I have also made a 3mm probing rod out of silver steel and put an insulated shank on it so I can using the tool setting pad in either mode depending on whether the job is conductive or non conductive. The only thing I have done different to your videos is put all 6 newly installed limit switches in series into one input on the RnR card. The software knows if it is doing a machine zero use of the switches or a limit action by virtue of the status at the time. Again badly explained ...

[@sunny5rising]

Did the calibration work out ok? If i understood correctly, i think you should only need to subtract the tool diameter once (per axis) in your calculations or tool radius twice. Haven't yet set my machine back up since the hurricane here in NC, but when i do, i will test the machine coords issue. Just been busy helping folks clean up and repair around here.

[@alanwood3597]

Hmmm ... you have got me thinking now. I have the probing backoff set to 1.5mm and I had a 3mm diameter probe. So what I really meant was 2 x backoff plus 2 x tool radius which I mentally was thinking as twice tool diameter which is technically a wrong way to describe it .... I just did an edit to the Mach3 operational screen by adding a LED next to the tool height button so you can see/test the probing contact. Found instructions on CNCnutz (Peter Passuello) KZbin site. It saves having to flip screens when testing the contact. Some pretty raw pictures of the hurricane shown on UK TV so good luck with the clean up.

[@sunny5rising]

Interesting about the LED. Thanks for the tip. I'll have to look into that.

[@WakaTattoo]

www.dropbox.com/s/ryqnuv9mjnly769/External.txt?dl=0 Eliminate the tenths and the format of the data on line 218. It is what gives the problem is not a definitive solution, if someone can fix the problem of the format I thank you. That way it works with whole numbers.

[@shaali4900]

Thank you so much for the tutorials, I setup the script with you brilliant instructions on a USB driven machine. Scripts are very touchy to say the least :) they work 50% of the time perfect. but other 50% they have broken bits and rolled away with the part :). Not sure what the problem is.

[@sunny5rising]

I'm not sure, but it sounds like there is a bottle neck in your system when it comes to the probe signals. Possibly the USB connection itself.

[@shaali4900]

There is virtually nothing running on machine except Mach3. I checked the resources, look good. I also tried different USB cables and ports. The Auto Z script, from time to time, after touching the plate, will push the cutter down a mm and then goes to z safe.

[@sunny5rising]

The computer dedicated to my CNC is pretty bare as well. For the z script, try increasing those Sleep delays I mentioned and sees if that helps.

I have a usb connected machine Can you help me on finding a tool zero script for it. my tool zero doesnt show pins under mach 3

[@luislanga]

I tried this on my machine and got a few errors on Mach3 v3.041. After reverse engineering the whole script I found out all I had to do was change my VarStandOff, VarGageThick and VarProbeDia to whole numbers, as "VCATCH" was returning the operation between these variables with a decimal point and mach3 apparently didn't know how to input decimal values into my xyz coordinates, the first time I tried it I got -28715 or something like that, good thing I have limit switches, cuz I sent it g0x0y0 before checking where the machine thought it was. I guess it could be easily fixed if you don't have a whole number diameter probe, but I don't want to read through VB script or Mach3 documentation right now. Thanks for sharing, Charlie!

[@sunny5rising]

[@speppino]

Hello Charlie, I tried your script with a 6040 Router from ChinaCNCZone. This has a USB controller and none of your script work or some partially worked but then I could not repeat the results more than once. In addition I got many errors. In particular, when I run the edge finder I get " Maximum travel reached...." which I tried multiple distance but still the error pops up. but this error in not consistent and once or twice I was able to succeed but they the DRO was not peftectly zero after the measurement, but x was +12 microns and Y +19 microns on the display. but after I was not able to measure it anymore. The error keeps coming back. For the " external center finder" I get the same error right after the probe touches the first side. Once I was able to touch one side and when the probe went to the other side it stopped giving me an ( Hope I remember correctly 322). For the "internal center finder" in a circle ( i checked the circle option) the probe touches one side, goes rapid in the starting point, moves to the other side and after it touches goes rapid back to the opposite diameter and it stops with an error "error on line 277 -Internal error . In addition a couple of times once it stopped, the machine started moving again on its own with no reason. fortunately at very low speed......it is scary and fortunately I used foam with aluminium tape to test all the options. Unfortunately nothing works or is extremely inconsistent and dangerous to test on real parts. I hope you can find the magic solution for this. Thanks a lot for your hard work.

[@sunny5rising]

Thank you. Glad you enjoyed the video. The feed rates in the scripts work fine, but you can change them as you wish. You will need to be sure there is conductivity between the probe/tool and part/touch plate. You can test this before running the script by temporarily jumping the contact points with a piece of wire and making sure the "Digitize" LED lights up upon contact. If you are not sure that there will be conductive contact or are afraid to run it, DO NOT RUN THE SCRIPT. Hope this helps to answer some of your questions.

I’m running Mach 3 Ver R3.041 Thank:

[@sunny5rising]

Hello Larry. Thank you for the compliments. Since you're using an older version of Mach3, we may have to customize the script. Email me at [e-mail] and tell me which Revision of the script you are having issues with.

[@TomEF0361]

Hello Charlie, thank you very much for your scripts and your support for this CNC/MACH3 | Automated tool setting | Edge/Center Finding (X/Y) | Includes INCH/MM scripts. I have a question. Is it also possible to create a script to measure the workpiece position with "corner angle"? Angle of Surface?

[@sunny5rising]

Thomas, you're welcome. About the angle question... I am currently working on a probing script to set coordinate system rotation angle (G68). Not sure if that's what you are referring to.

[@TomEF0361]

@@sunny5rising Yes Charlie, thats the right way what Im looking for. Have seen it on new Mach4 but I will not change my Running System :-) 1000 thanks for you work!

[@doubletop12]

Charlie I had this working fine until recently and I needed a system rebuild. Now I have problems with the internal and external centering but the X/Y edge finding works fine. The problem I have is at the end of the code the tool doesn't center on the midpoint and the DRO's don't zero. However, if I single step the code the tool centers correctly and the DRO's zero. As I said, edge finding works fine. I am guessing some sort of timing problem, but tweaking the sleep values in code doesn't appear to make any difference Mach3 V 3.043.66 and Center external script Rev 16 and Center internal script Rev15b. Edge finding scripts Rev13 Any clues on what to investigate please?

[@sunny5rising]

If you would, Copy and Paste your modified version into a text file. Send it to me at [e-mail]. I'll look it your edits and maybe make some more.

[@doubletop12]

@@sunny5rising Charlie Will do. I think I have found the problem IsMoving() jumps out of the loop early and the DRO's are still changing. I think you have found a similar problem because in the edge finder scripts I see you have a Sleep 500 after the axis move and IsMoving. The trouble with a fixed delay is it depends on the speed of the move. If you reduce VarFeedRate you require a bigger delay. Although I have now included Sleep 1500 between the last move and the DRO read I also have code that loops and reads the DRO's until they have stopped changing. I am doing some more tests and will then send you my revised scripts By the way my controller is an NVCM USB device. Pete

Hi Charlie, best work is yours automated tool setting. I am beginner in that world, can I have your good scripts for update my selfmade cnc ? Thanks. Best regards

Hello. Yes, the link for the scripts are in the video description.

if i do manual edge finding do I have to input the diameter size of the edge finder or can i travel half the distance of the edge finder?

[@postiemania]

I have to try this, thanks Charlie

[@sunny5rising]

You're welcome.

[@dansv3872]

One problem i had was that my z was going down for some reason or because i'm stupid, so i replaced the line with G91 Z15 . Another problem i have is that i always get "Maximum Travel Reached. Reposition X Axis Closer To Part And Try Again" so i removed that if statement , Another problem i have is that even if set Span to any number , the tool moves until touches the probe then it pushes into it faster a few mm more , after that it goes to the other side but it goes too far away . Is very weird ,maybe i'm doing all wrong....

Dan, email me at [e-mail] and I'll send you another script to try.

does external center covers outside diameter of a circle?. i noticed internal center does have circle option

[@sunny5rising]

Helo Rengan, the external center script can be used to check diameter, i just didn't program it to do it automatically (for safety reasons). To check diameter, run the X-Span, then the Y-Span. This will center the probe. After that, again run the X-span (making sure to not move the Y axis when resetting the probe up), then check the X-Span reading. Run the Y-Span again (making sure not to move the X axis) and take its reading. Those last two span readings will show the diameter on their particular axes.

internal center button is not available on my mach3, any help would be appreciated

[@hellarms]

Thank you for the tutorial and script. Can you please help me to solve the issue witch I have? For example, when I click on the button External center I get error: Error on line: 72 - Sub or function not defined: MachMsg. When I click on the Auto X plus button I get error: Error on line: 57 - Sub or function not defined: MachMsg.

[@sunny5rising]

Sounds like you might have an earlier version of Mach3. What version do you use?

[@rprilutsky]

I am having a problem with internal center script. Probe moves toward x+ normally until prob touches the part. Then it returns fast but does not slow down and moves fast toward x- until i have to hit e-stop. I am using mach3.r3.43.62 . What could be the issue?

hi, your viedeos is helbful. A Question? Can you post a auto tool setting with fix position z toll length? thanks

[@GurusOnWheelsSalisbury]

my spindle bit is already making a connection through the spindle and to the aluminum bed . if i clamp a piece of aluminum in the clamp and clip one wire to the bit and the other to the object im already making a complete circuit through the spindle before even clicking a button . the digitize light is already on . how do you overcome this ?

[@sunny5rising]

You will probably have to isolate the part, either by cardboard or wood between the part or the bed/clamps/vise. Alternatively, you might be able to isolate the tool by putting electrical tape around the tool shank before you put it in the spindle.

Not quite sure. I'd have to learn about it and experiment with it.
