CNC Mach3 | Tool Setting Touch Plate | Auto Tool Zero (Z Axis) | Includes INCH/MM Script

[@davidvelozee]

Sir, thank you so much. Works like a charm. Love the audio! TROUBLESHOOTING: For users who are using a USB to DB-25 pin converter and you don’t see the “LED’s” light up in the “Port 1 current state” section (at least they don’t for the ebay version of the dongle), follow along with everything else, but at the CONFIG -> PORTS AND PINS -> INPUT SIGNALS section the “Automated Setup of Inputs” button will not work. Instead enter the following information manually (NOTE: this is for a JP-382A controller board). Scroll down to “Probe” - Enable: CHECK, Port #: 1, Pin Number: 15, Active Low: CHECK, Emulated: X, HotKey: 0. Click OK and continue with video. You still won’t see the LED’s light up but it still worked for me.

[@sunny5rising]

Thanks for the detailed explanation. I'm sure it'll help some folks out.

[@billllewellyn1571]

@@sunny5rising Hi Charlie. I love your set up it makes me happy. May I please have a copy of your script please. Bill

[@bobbailey7024]

Hi David, My old parallel port computer died and my only choice was to buy a newer one with Win 10 installed (what a dreadful system). I had to buy a genuine UC100 USB to parallel converter, but I eventually got it working. I was almost stopped dead in my tracks because I grounded the probe and no LED illuminated in the Diagnostics page. I have no idea what the board is, probably a Chinese knock off but the motor outputs are X axis 2,3 Y axis 4,5 Z axis 6,7 and A axis 8,9. Thank you for restoring my 'will to live'. I shall give your suggestion a try.

Pro Tip: Don't tighten your endlmill. Then when you realize space bar can't stop it, you save your cutter. :) Nice video. Works for me except I had to wire my touch plate the opposite of your diagram. I'm very happy, I'm going to spend the next 30 minutes homing my mill over and over.

Thanks to you, I've been able to use it very comfortably for the past few years, and I'm just now thanking you.

BUT, the good news is that the MACH screen shows the Z axis moving to a height of 21.336mm, which is the default plate thickness of 20.066mm added to the default 1.27mm of stand-off distance above plate. Voila!!! Didn´t install the voice messages, it seems a bit of overkill. Many thanks again!

I have a gauge like yours and when i short the ground to the gauge i also get a probe light. When I connect the clip lead to my endmill and try and get a connection no go.

Thanks a lot for your wonderful content. I have a question :D I have used many hours and now I thought it was time to reach out ! I've got a CNCz 6040 China Machine, Mach3 and a windows 7 computer. I can move my cnc, run programs and stuff- spindle works, but when I go to Mach3 Diagnostics there are no green lights showing at Port 1 pins current state? How is that? I ran a monitor program to check my ports activity and could see there were some ports that were red and some were green. Well all this began because I wanted to use my touchplate probe... I can press the auto tool zero button- but I doesn't stop it movement down the z-axis when it touches the plate. BUT----I can only use the auto tool zero if I have my active low unchecked- as soon as I check the active low setting in ports and pins input for the probe it doesn't work. I can see the digitize light is green when active low enabled. And it doesn't flash or turn off when i test the probing plate. What is wrong? Could it be a missing ground connection in the controller box for the probe? Or electrical noise? Or my setup? A bios thing with printer port? I know the CNC 6040 are not the best built machines, but it is all I could afford ::) I hope I dont need to solder stuff and rewire, as I am not so proficient in electrics.

[@martindekker8203]

ok I have it set up as you suggested and I'm having problems with Z not going to Zero. My touch plate is 19.2 mm and this is the same measurement I'm getting in "Machine Coordinates" while, with "soft Limites" on or off and Machine Coordinates off I am at Zero in Mach3 but my tool is not at Zero and is about 5mm above my zero. What am I doing wrong? Also, do you need to set all your axises to zero in both soft, normal and machine coordinates before auto zeroing? Cheers ps: touch plate, touch plate, touch plate lol

[@AgentWest]

Thank you for the script and a good quality fun video that explains how to use it! That being said, for some reason after touching the probe my CNC would go to top Z, hit a limit switch, then set DRO to probe thickness. I ended up removing a bit of code from the script ("Move to contact point due to overrun" bit) and it's been working flawlessly since. Any idea why my machine could be acting that way when yours worked fine in the video? I'm using Mach3 with MKX-IV control board. Probe/plate wired to "probe" on the board.

Hi Agent West, I have the same problem. Had the probing script crash into the plate a few times... disastrous... the tip was supposed to move up (in positive direction), and it does 9/10 times... Anyways, highly recommend doing a soft touch pretty much all the time until you are sure the script works. I'm using Mach3 USB. The best I could figure was that some of the code (OEM LED and OEMDRO) correspond to different fields for me. Switching between the workpiece/machine coordinates, I realised that the script was zeroing my machine coordinates. As Agent West suggested, I also removed the bit of code from the script ("Move to contact point due to overrun" bit), and changed all the G90 to G91, now the code works.

[@AgentWest]

Ah, makes sense if it was using absolute coordinates instead of machine coordinates.

This script seems to work, but it doesn't zero the tool and wont let me move the machine or anything until I hit escape. For example I zero Z axis 5mm above the machine bed, run the script and it then stops when contact is made leaving Z axis at - 4.90. which kind of makes sense as my plate is a 0.1mm shim. Am I missing something or misunderstanding ?

[@sunny5rising]

Thankyou. Glad you enjoy the script. Yes, I'll do a video on how to do this soon. If you can't wait, download one of the several Screen editors ( at MachSupport.com). I use either Screen4 or MachScreen. Open your screenset and look at the Z AutoToolZero button information. Within there you can set a hotkey.

[@yannpenhas9280]

Hi Charlie ! Nice video and great job on the script. I try to put that in place on my DIY CNC. It works fine except just one issue : I have limit switches on X, Y and Z and the Z limit switch triggers when the tool touches the probe. As a consequence, the CNC stops in emergency instead of finishing the script. Do you see any way to have the script work fine while keeping the Z limit switch feature active for the rest of the operations? Sorry if it is a stupid question, my level in Mach3 is not far from noob :) Thx for the support

[@yannpenhas9280]

I forgot to mention that my probe is on the same pin as my Z limit switch. So the expected behavior would be that the Z limit switch activation does not trigger CNC emergency stop during Auto Zero Tool script, but reactivates normally after the script is finished

[@sunny5rising]

Apologize for the late reply. There might be a way to disable Z limit through scripting, not sure. I'd have to look into it. On another note, you could temporarily manually disable the Z limit (ports/pins_Inputs) while using the Z_axis script. Before running the script, make sure the digitize LED does light upon contact.

Haha, I won't crush it, I'm testing with a cheap end mill not tighten too much and on a foam block... I'll try to do some videos once I'm in the shop

Hi Charlie I want to ask you if it was possible to insert in the script a tool change type normal probe z, do the roughing, change the tool z 0 probe z that returns to point z0 I am waiting for your answer as soon as possible hello

[@sunny5rising]

It's definitely possible, yes.

[@ThePekeTsu]

Thanks for this informative video! Question: when I try to run the script, my z-axis goes upwards, not down. What should I change?

[@sunny5rising]

You're welcome. If you haven't tried both the v12 and v22 scripts, give the other version a try and see if the issue persists. If it does, let me know and we'll figure it out.

@@sunny5risingFor some reason, I had to add -1: Code "#100=" &VarMaxDistance * -1 Now it works perfectly!

[@sunny5rising]

Excellent! Glad you got it working.

[@spourabbas]

Thanks for the great video. I set up the z probe detect and it works fine! But some time it confuses and insteed of moving in z direction to probe it moves in X direction! Do you have any idea why it could be?🙄

[@sunny5rising]

I'm not sure why that would happen. There are no X movements in the script. Sounds like some sort of system issue, but I have no idea.

Eu estava com mach3 263 deu esse erro - "Erro na linha: 54 - esperado: =" instalei a última versão do Mach3 (R3.043.066) ficou perfeito. Muito obrigado.

[@KAFA2020]

I am really happy for your awesome video. I am facing another problem. I am using mach3 for my CNC machine. But here in BD, we face load-shadding. Sometime I load a long time design but in the running time electricity cut off . I can not damage costly wood. Therefore, If I want to re-start the work from the same point where the machine stopped , What is the procedue for MAC3 system? Please could you help me? I will be grateful to you.

[@sunny5rising]

I will have to do a video on this topic. There are several ways to continue an interrupted job in Mach3. Which way to do this depends on several factors (home switches installed or not, CNC program written in absolute or incremental mode, for examples).

[@KAFA2020]

Dear respected@@sunny5rising​, Please sir, I am facing some problem about the load shading. Here in Bangladesh, electricity cut off frequently. After completing almost 50% sometime 70% of the total program, sometime electricity cut off, then I can not re-start the program from the line where electricity cut off. Therefore, I need a good solution about the uncompleted design. Please sir, could you help me? I need your help

[@KAFA2020]

Dear sir, still I am waiting for your response. Please sir, I need your help.

[@sunny5rising]

Try this... kzbin.info/www/bejne/baqkdouDYtekZ6c

[@Shopbuilt]

Would there be a way to edit the script for a different axis other than Z?

[@sunny5rising]

I also have a video and scripts for XY. kzbin.info/www/bejne/g4KciYdpZdhghrc

[@naidenhadjiev922]

@Charlie Sarsfield Hi, thanks for the video man, it explains all the steps very well, I get this message "This is only for the printer port modes!" when I click on Automated Setup of Inputs. I can't continue.... what should I do?

[@sunny5rising]

I haven't ran into that situation before, but I would imagine that you should still be able to manually insert the Port/Pin number and Enable the probe. If you don't know the pin number, you should be able to cycle through pin number options till you find the one that works. I do use a parallel port, so perhaps it's why I haven't heard of your issue. Not sure.
