**Sorry for the rotten video this time. I don’t know what happened to the exposure settings on my camera.**
In this video, I’ll demonstrate and discuss the addition of a second Z axis touch plate to my @AvidCNC 4848 Pro CNC Router.
First I’ll show you the parts required for this modification. I’ll run the M12 cable and connect the 2 touch plate M12 cables to the controller box. I’ll wire the 2nd touch plate and connect it to the M12 cable.
In Mach4, I’ll show you how you how to adjust the thickness of the touch plate being used at the time.
Finally, I’ll wrap up by discussing the reason for using the two different touch plates.
As usual, if you have any comments or questions about anything I covered in this video, please join me for the Live Q&A, or put ‘em in the comment section below.
On Sunday, February 5th, I’ll be hosting a LIVE Q&A session, where you can ask your questions pertaining to anything I’ve covered in this video. That Q&A starts at 3 pm Eastern time, Noon Pacific time. Hope to see you there!

Good video Mark Thanks for sharing. I know this video was created a year ago so i can't be in the live stream :( but great info.
Great video! We have 5' x 12' AVID with exactly the same issue. Probably will implement but make a 1" thick plate so no setting have to be changed. Thank you again!
You and me must be telescopic Mark! Only just thinking on how to zero a bit with Mach3!
Awesome video Mark. Thank you.
You just LOVE spending my money, My Friend! I’ll have to remember to send you a photo of the very simple modification that I made to better control my long AVID touch plate cord…
Haven't you heard, Rick? I'm an expert at spending other people's money. Spoiler alert - I'm also an expert at coming up with things for other people to do. :D
Nice upgrade as I have the even larger Amana surfacing bit and have been using paper to zero. Also, a good tip on checking for continuity on bits as I broke a boring bit (teflon coated) and put a nice gouge in my Avid touch plate. If I do this upgrade, it would be preferable to find a 1" thick plate (or make my own) as the touch plate thickness difference would set me up for a human performance error that could be avoided. Steve
Thank you, Steve That's an excellent point about making a 1 inch thick touch plate. If I knew what I was doing when it came to metal, I'd try that myself. Maybe one day...
There's a bit of nuance on how you write your auto-tool-zero script. A good script will probe twice. First, in a high speed, then back out a milimeter. Second, probe at a snail's pace, to find the exact micrometer
If you machine a lot of metal or plastics and you need 4 digit resolution, then I completely agree with you. For woodworking like I do, 4 digit resolution is a case of massive overkill. Half the time I don't even need 3 digit resolution (I'm an old-school woodworker who came up through the cabinet shops where we had a .03125 inch/0.79 mm builder's tolerance.) Still, your point is valid, and if the type of work you do requires that fine of a tolerance, then by all means yes - pursue the most accurate method that suits your work.
@@MarkLindsayCNC Do you utilize rest-machining? As you know, In RM, you have to be super accurate on your Z, or else you get a silhouette.
Great mod Mark! I suspect Mach 4 would allow you to add a drop down or set of radio buttons to the main probe screen... I'm not a Mach 4 expert, but I've fumbled through a few UI improvements.
Hmmmmmm... Thanks for giving me an idea to investigate, Greg!
Hello Mark! Nice and informativ video as always 😊 I wonder why you don't but the ground permanent to the motor mount for example. Then you don't need too fiddle around with the magnet evry time. 🤔
The magnet takes 3 seconds to attach and remove. In this video, I was testing the bit to see what was conductive and what wasn't. I have some bits that are painted and are non-conductive. I wasn't sure about the surfacing bit.
@@MarkLindsayCNC 👍
Great idea. Looks like you need to have a piece of aluminum milled to the same thickness as your Avid plate then you wouldn’t need to reset the setting.
I talked about that during the Live Q&A. ua-cam.com/users/liveX5XqSIxUnFk
id be machining one the same size
The point of the video was to show folks that they have options, and how to put those options into effect.
Cool. Wonder if you could leave the avid config as is in Mach4 and just use G92Z-.381 whenever you use the other touchpad?
I probably could. I'm just getting into that, so I haven't tried it.
Hello Mark, been watching your channel for a while and finally bought a avid just like yours. I wonder if you could see what you think about this. I used the spoil board file from avid and all my rows were off by 4-5 mm. Not sure what happened. So I made another file to match my rows perfect. Ran the file after using the touch plate on the lower left corner and I was off again 4-5 mm. Past where it should be towards the back of the machine. I know very little on all of this and just want to get my top cut. Seems like a off set problem? Thanks for and help you can spare. I think I might have found my problem.. After watching your video again. I had the tool size in correct. Still had it at .5 from tramming it. Going to re run it
Something else to remember to do is check and adjust the calibration of each axis. Jim Neeb did a great video on axis calibration on his Avid CNC about 3 years ago (He's a member of the Avid forum as well.) Here's a link: ua-cam.com/video/E5H7Fsrq95c/v-deo.html
Thank you so much@@MarkLindsayCNC
Why not just switch the touchplates?
