Are You Ready to Learn to Write GCode for Your Touch Plates? 

Greetings, I just wanted to give you a couple of tips on your code. At the beginning of your macros if you define G91 you don't need to enter it over and over. It's defined until you change it EX: G20; G91; G38.2 Z1.5 .... G91 is now defined. Also G0 has been defined too many times. G0 X; Z; Y; each instance after the ; is a separate command and G0 is carried thru. You only have to redefine if you alter the scheme such as a G92 command. This being said I have cleaned up your code. This is what is running on my machine at the moment. G20; G91; G38.2 Z-1 F3; G92 Z.255; G0 Z.5; X-1.25; Z-.75; G38.2 X1 F3; G92 X-.377; G0 X-.375; Z.75; X1.145; Y-1.25; Z-.75; G38.2 Y1 F3; G92 Y-.377; G0 Y-.375; Z.75; Y1.145 Notice only 3 G0 commands. Just wanted to help you clean up your code. I have designed 2 versions of the macro above with a .125 offset for .25 mills and a .0625 for .125 mills so I don't have to keep recalculating the offsets. I do thank you for the idea of the plate design and for explaining in English terms what can be confusing to many. Hope this helps in future endeavors.

Thank you for the thorough explanation. While converting to Metric to help my brother, I took the liberty to convert the hard-coded values into variables so anyone can just change the values and not mess with the gcode itself. This gcode is in METRIC system. If you want to use Imperial, change G21 to G20 and your variables accordingly. Cheers! ;VARIABLES #101=6(PROBING BIT DIAMETER) #130=50(FEED RATE) ; #102=10(TOUCHPLATE WALL THICKNESS FOR Z PROBE) #103=15(TOUCHPLATE WALL THICKNESS FOR X PROBE) #104=15(TOUCHPLATE WALL THICKNESS FOR Y PROBE) ; #105=-20(MAXIMUM AMOUNT TO MOVE Z IN ORDER TO FIND TOUCHPLATE - down) #106=15(AMOUNT TO MOVE Z AFTER Z PROBE - up) ; #107=-40(AMOUNT TO MOVE X BEFORE X PROBE - left) #108=-20(AMOUNT TO MOVE Z BEFORE X PROBE - down) #109=15(MAXIMUM AMOUNT TO MOVE X IN ORDER TO FIND TOUCHPLATE - right) ; #110=-15(AMOUNT TO MOVE X AFTER X PROBE - left) #111=10(AMOUNT TO MOVE Z AFTER X PROBE - up) #112=40(AMOUNT TO MOVE X AFTER X PROBE - right) ; #113=-40(AMOUNT TO MOVE Y BEFORE Y PROBE - closer to you) #114=-10(AMOUNT TO MOVE Z BEFORE Y PROBE - down) #115=-20(MAXIMUM AMOUNT TO MOVE Y IN ORDER TO FIND TOUCHPLATE - away from you) ; #116=-20(AMOUNT TO MOVE Y AFTER Y PROBE - closer to you) #117=20(AMOUNT TO MOVE Z AFTER Y PROBE - up) #118=40(AMOUNT TO MOVE Y AFTER Y PROBE - away from you) ; ; 3 AXIS PROBE G21; G91; ; START Z PROBE G38.2 Z#105 F#130; G92 Z#102; Z PLATE THICKNESS G0 Z#106; ; START X PROBE G0 X#107; G0 Z#108 G38.2 X#109 F#130; G92 X[#103+[#101/2]]; X PLATE THICKNESS + PROBING BIT RADIUS G0 X#110; G0 Z#111; G0 X#112; ; START Y PROBE G0 Y#113; G0 Z#114; G38.2 Y#115 F#130; G92 Y[[#104+[#101/2]]*-1]; Y PLATE THICKNESS + PROBING BIT RADIUS G0 Y#116; G0 Z#117; G0 Y#118;

Paw Paw... I always feel so bad when I forget to like a persons video so I have now gotten into the habit of clicking the "Like" at the very beginning of the video. Thanks for all you do in the world of RU-vid.

Every moment that is better and better , now a im passing to the dark side..tks for share Paw Paw´s Workshop your deserved like again..!!!

Starting my beginners learning. Lots to learn wish me luck but I am in no rush plenty of time to learn on the weekends

I definitely needed to know this information since I have to write my own code for the touch plate. Funny part in the video is when he mentioned that if you have any questions post it in the comments. Who in the world would have any questions after looking at this, this video was 100% thorough with no confusion and everything was explained so simple.

Outstanding. I work in cnc and your video will make it easy for the inexperienced to set up their 3 axis probe with no issue.

Today is the first day of my home built CNC machine. And what you have taught me here I will do very shortly. Thanks very much for the great information!

Thank you sir! I just made me a round touch plat and works wonderfully. Im gonna use the knowledge you and others just gave me and whack two sides off my round one and make a 3 point button! Thanks for your contribution, the G-code and for the stuff I dont know yet!

Great Video, a lot of good information!

Thanks this helps explain it more even for me. Since this was over a year ago to try and help others. I also wanted to mention there is a newer version of UGS that has (return to zero) button which might make it easier to return it instead of doing it by typing it in. Also the new version you can move xy and z independently now so you don't accidentally jam your bit into the board buy forgetting to change xy movements which might be higher increments than what you'd like to set Z movements for. Great stuff Paw Paw!

Great. I'm an ex CNC turner so this all made sense. I didn't know the commands you were using but now I do so a great big thank you. I just bought a Z probe kit but not got it working yet. ( Keeps throwing up errors) so now I can go an troubleshoot what's not right (I hope) Thanks again. Jim

thank you for the great video, I was having problems with my probe set up and went step by step with your video and it works fine now. I use your videos all the time as they are very well done and instructive .

Informative! Thanks!

Great Job, I really enjoy watching your videos, I learn quite a bit from them. Stay healthy and keep making videos.

Thank you for helping me understand the logic, your an excellent teacher!

This making more sense as I'm getting more familiar with G-Code. When you define the macro, it's tied to a fixed radius bit, it won't work if you change bits from say 1/4 in to 1/8 in

Good job,very detailed explanation and also good demo.

Thanks!

SUBSCRIBED!! THANK YOU FOR YOUR VIDEOS AND SERVICE. 🙏🏻

Thanks for the explanation, Better to open CNC Training class.

Thanks for the excellent tutorial you're a great teacher

Thanks..... great job Mr. pawpaw...

Great video. Wondering why the machine didn't already know where the 0,0,0 point was when you had entered all of the offsets. You had to manually enter the coordinates to move to 0. I may have missed something.

Great video pawpaw...soon u b 100k subscribers...

thanks

A little late to the party -do love your videos Since I use homing on my X-Carve inorder to get the probing commands to work I had to turn off soft limits $20=0 Cheers Mike

Excellent sir

Nice explanation, thanks. All ok with the weather ?

You failed to point out that the .5625 on the X axis is also - .5625 @time stamp 31:11 Thank You so much it helped very much!

Enjoy watching your show. Have you ever done a 3 axis probe on a X-Carve? Can it be done? Would like to see it done very much.

Why is the Z-1.0 command needed? Won't the machine automatically lift the spindle as soon as it touches the plate? What if you left out this command entirely?

I think I may have missed the use of the semicolon in writing the G code? Did you mention this detail? Thanks

Paw Paw, Where did you get the power supply box you use, and why do we need it?

Hi Paw paw . hope you well. I try make probe touch plate with mm not inch how workout for mm?

Thanks for that, big help. I have 1 issue, my touch plate thickness is .242 on x and y axis, I added .125 for half of a 1/4 inch bit.. .367 total.....my bit ends up not centered over corner of material but on the outside edge of x and y axis. I use bcnc and have homing switches on my Powerroute.

I’m ready To code with your video and the comments! Now when not using easel, but vcarve/ugs. After you probe and load the file. When you click send will it raise the bit a little automatically like in easel? Or is it something separate after xyz 0.

Hi I try make G code for mach 3 but not work no move just noting check below if right ? maybe I missing something ? G21 MM G38.2 Z-25 F100; G92 Z10; G91 G0 Z10; G0 X-50; G91 G0 Z18; G38.2 X25 F100; G92 X20; G91 G0 X-5; G91 G0 Z18; G91 G0 X50 G91 G0 Y-50; G91 G0 Z18; G38.2 Y25 F100; G92 Y20; G91 G0 Y-5; G0 Z18; G91 G0 Y50

What books do you recommend for learning to write G-code?

I have entered your macro code in my CNC using UGS but instead of moving in inches the machine moves in mm. I have the latest UGS platform installed.

does the g code apply to like running a laser Preston

Super grandpa🔥🔥

☺️👍👍👍👌♥️

Where did you find what the codes meant

Did you ever had an issue that zero in the center of your design in Vcarve and when zero the same on picsender and send code starts drilling a hole 3" bellow the design?

That doesn't look like the Easel control panel?

lo hago exactamente igual que Ud.lo único que cambio es el G20 por G21 y las cantidades en mm.Pues bien,el mandril se va para arriba.Ya me tiene loco.Me parece que me voy a olvidar de ésto y volver a la hoja de toda la vida

💐❤️🇮🇶

Thanks!
