How Mach3 Can Store and Recall Table Positions Using Offsets

The work offsets function of Mach3 is a very handy tool. It can memorize positions of your table and recall them quickly. This video shows how to use them in a simple quick way.
This is also useful for programming a position for tool changes or other maintenance.

lord... been reading all sorts of threads... asking questions of mach3/warp9 folks... none of which suggested this to me. this is all I needed and I'm very thankful you posted it! thanks

[@rbalker]

I read the manual several times trying to make sense of this but was still confused. You explained it so well, it all makes sense now. THANK YOU.

[@geofferyshanen7758]

I have spent hours watching videos to learn what you just taught me in 10 minutes….. outstanding video….. Thanks!!

[@leewimbs1773]

Excellent explanation. Have been using Mach 3 for a couple of years and never really understood offsets. Thanks for doing a simple, well described, training session of offsets.

[@kelleysimonds5945]

You are the best source for info on Mach3. They should pay you for your clear explanations.

[@postiemania]

I have been watching Gurubrew for 5 years now, always come back for his tutorials. Clear precise and appreciated.

[@doug9121]

Thanks for all the help you happen to be the best for fixing problems with Mach 3. Hope you are well

[@trondwell13]

subscribed - Correct video title - straight to the point - single subject explained

[@jasonlong30]

thanks so much. I just broke my bit and have to wait until after the weekend to get a new bit and I was concerned with losing my position after I turn my machine off. This work awesome and it saved my g55 even after machine was turned off. Very Helpful... GuruBrew for the win.

[@OdyZeus]

You seriously explained it so good! I've seen other videos trying to set up my offsets and they talk like experts, but they don't explain good! And you did it so simple and so understandable!!! 🙏🙏 Thank you!

[@MrSkeeteman69]

you really explained it perfectly. now I'm begining to understand the whole offset thingy.

[@anthonykalogerakis9673]

ive had mach3 for 1 week, your video helped out alot, its helped me understand the offset section and how to set up fixtures, cheers mate!!

[@raulirimias4810]

Very neat video. Thank you Guru Brew for sharing your experience with the rest of the world.

[@benwarren250]

This is exactly what i was looking for! Very concise and to the point and simple to understand. Thanks

[@mereskimade]

This was very helpful, best description of the multiple G54-G55 etc I've seen yet.

[@gregmiller8293]

Thank you for showing you can Home over the material you are cutting and not just the lower left corner.

[@rchavez5056]

All this time has passed and I never knew what "Go To Zero" did. Thanks for the informative video. I hope you are doing well. It's been a long time since you have posted.

Fantastic - just the video I was looking for! Thanks.

[@ramirogonzalez1048]

super clear and usefull! what cnc are you using? Thanks!

[@maccaslasher]

A big help thank you. One thing im struggling with tho..... xy datum position is always centre on my jobs, i cant understand how to set that when using an offset. i click in the middle of the circle it shows but the machine acts like xy datum is at a corner

[@andreww6738]

Awesome video, thank you. Always enjoy your vids, so helpful ! : ) I havent got my machine up a running yet. Decided to go with a Masso instead, so hopefully I'll figure that stuff out soon.

[@muharremgumus1830]

This is very very usefull video. Thanks for sharing this info. You are great

[@ianbertenshaw4350]

Totally new to cnc and mach 3 and been having a hell of a time just getting the machine back to home after running a programme , if i go to machine co ordinates after the programme has run and click on go to zero only the z axis moves . So if i make a part and use G55 as my tool offset can i put G54 at the end of that code to tell the machine to go to home or machine reference zero ?

[@shaunwhiteley3544]

Love the Mach3 videos, please keep them coming 🙏👍👌😀

[@andywah9413]

Very well explained thanks for sharing!

[@omskariyazmaraikayer913]

Brief and clear . Thank you.

[@angellee5253]

thank you. very good and clear video

[@IH1940HAY]

Have been using My DIY CNC for 18 years and never used or understood offsets, I understand now, but I just do one at a time using a jig so didn’t have a need for offsets. But if I were using multiple jigs I know how to now. VERY good explanation. Could you do a YT on MACHINE COORDINATES? Thanks

[@Peter-qd2wp]

Great explanation. Thanks for your videos.

[@ZeroMod]

Great clear explanation - THANKS!

[@danballarin]

8 minutes of my time well spent! I just tried to read and understand this for the past hour and got nothing.

[@mrgodBG]

this was simple and helpful! ty

[@rickmccaskill7888]

Thanks. I have been trying to figure this out. Now very clear. How does the Ref All Home button work? I click on it and knowing happens. Any help would be appreciated.

[@kwk8363]

Thank You for the video, it was very helpful for me

[@martindekker8203]

Did you set all your offsets from home G54 ? It looks like the way you did it won't get you to any offsets from home. Just wondering if its better to set all your offsets from home and not from another offset point. Very simple explanation though. Thank you

[@peterandrade4313]

Excellent video and very well explained. I using UCCNC software and hopefully this will be similar.Thanks again.Peter

[@stevemorton7141]

I have 4 offset values in my gcode program. I selected a corner of my work piece and then 0,0 for G54 offset. I then referenced 3 other locations from G54 on the work piece and then zeroed each one as G55, 56 & 57 offsets. The program runs perfectly. When I exit the code I hit fixture save. When I reload the code the 3 offsets are in the correct location to each other but not the G54 0,0 position. How do I save the offset locations correctly when exiting the program? Thanks, I really loved your demonstration.

[@HagerHay]

I saw one of your videos where you had I think a felt tip marker mounted on the router head where it was offset from the bit. And you went into mach3 and configured a button that would shift the XY zero to that position, then press another button to return to the XY of the bit. I can’t find it again. This method is similar but I would like to have the other one where it would be permanent on my machine. Thanks

[@alirezamirabdolbaghi651]

Nice explanation, thank you

[@robjupp]

Now I get it! Well done and thanks.

[@maciejkulczycki3882]

Thanks! One cannot find it in stupid manuals!

[@dsaworxcarpentrysolutions9155]

Nice explanation 👌

[@bcoopx]

Nice explanation, thank you for sharing

[@antonio_cataldo]

Thank you for this tutorial. After choose fixtures, can I start a program and automatically repeat that program for all fixtures?

[@vigenboghossian6452]

Do we need to save position of every g offset or not

[@MrGitsum69]

When setting up different starting points and running a program; can you have Mock3 switch to a different starting point to start on another program on the opposite side of the machine without having to stop?

[@jasepotts2865]

Hi, do you know what the VB code is to select a particular desired offset? I tried copying the code from the mach3 offset screen but that just gives an error.

[@mazin_0_0]

Thank you, does this work the same way as NK 105?

[@JeffWoodshop]

Love the video : I am a daily mach3 user . I know some but it is not my friend. I have a pretty cool screen set the big tex screen might want to check it out. Pretty nice running ATC but in manual tool changing so basically all tools on one file. It would make a pretty good video there is also laser x y position. Big fan thanks for the video and your time.

[@nazarshah7242]

jaza kalla (thank u) from pakistani nation

[@chanbaik8970]

Awesome video, thank you., BUT, CAN YOU TELL ME HOW TO SET THE X, Y, AND Z ZERO? FOR THE FIRST TIME

[@brianway]

Hi, I am new to the Mach 3 world, I understand how to create, and use offsets, but how do I save them permanently? When I power off/on, they are always gone. I even hit "save" when I'm done. Great videos, thanks for all the effort you put in!

[@jimgeorge6220]

Go to config, fixtures. and save your settings.

[@pemptusioths]

youuu... i like you. you are the best! That was very helpfull !

[@иньянь-е8м]

Спасибо вы помогли разобраться .

[@nadermerizian5990]

your videos are great, well explained. I couldn't find anybody that is able to do Automatic home. Let's say you went to fixture 56 and the machine finished the job completely, what command do you tell the machine to go home automatically, without pushing Ref all home, is there a code command for that. thank you for your effort of these great videos.

[@jamesoathout7541]

G00G53Z0X0Y0 Will send it to MACHINE ZERO (HOME).

[@nadermerizian5990]

Thanks James for the reply. Since you are so good at Mach 3, I want to throw another question at you. let's say you have 3 or 4 parts and want cut them all at once without going home and start from the beginning. I have fixtures set up already at certain positions on the table of the mill, how can you add, let's say fixture No 56, 57, 58 and so forth to the g code. Do you have to copy each fixture to one Note pad and give it a certain name, and then load that g code, or is there an easier way. thank you in advance.

[@talgtalga3767]

@@nadermerizian5990 Hello.. did you get anwered ? i have also same question how did you all these four apporation you got note pad each and download g code and they run for each fixture 56, 57, 58 or one by one ? please need help

[@shamimmoohebati]

Now if you have to change tools and need to "Auto Tool Zero" how do you manage z offset for the rest of fixtures?

[@mattwagner602]

great explanation thanks!

[@stanislasnguimatsa2555]

Salvation please Mach3 does it have a scale function to increase or decrease a drawing if so how to adjust it I made drawings in mm but during machining it is a larger drawing that I see on my board

[@mdsharook894]

fixture save position after power shutdown and any time?

[@mohammadsarfarazi4866]

Hi, it was great, I have a problem, please give me a solution, when the machine is electrified, when the power goes out, the CNC loses itself and I have to do the work from the beginning ... Please help me and email me the answer

[@Ahdevefa-go5ts]

Thank you, may I live long 😊 senin için dua ediyorum

[@klausmadsen3639]

Hi, great video as I wrote earlier. I haven't got my machine yet so I am just trying to learn Mach3 while I am waiting. I have tried to do exactly the same as you but it goes to the same "0" points all the time??? Can that be because I have no machine connected or...? I would not think so and everything else seems to be working, so what can it be?

[@dptp9lf]

Great Video Steve!

[@KAFA2020]

Dear sir, I am facing big problem with my Mach3 cnc machine. Here, we face frequent electricity cut off problem. Sometime when electricity cut off, all the X, Y, and Z value in mac3 are changing when restart the machine again. Can not start from the same point where it stopped to work. It wast my expensive wood. I want to start from the same point where it stopped. Is there any solution to solve the problem? Please could you help me to solve the problem?

[@danpesonen2774]

Awesome thank you. Had my CNC mill for 17 years and never once have I used a fixture. Always nest in CAM or jusr add multiples to the CAD... So stupid I'vebeen

[@rufustoad1]

Hi Guru, I noticed you do not make many video's anymore? When you were zeroing each offset I noticed that Z axis was the last to run. I think if you were to zero all then return to that point you may have an issue if you already placed the part on the table. Any way to change that?

[@Nocadleeeee]

Why does my mach3 forget the coordinates i set under g55 and so on? Is there a way to set the default zero to be in a specific set by my position?

[@Yaroslav_Tselovanskyi]

How do you jog multiple axes at the same time?

[@leewbox3326]

have you by any chance made a script to zero the tool every time you change to a different tooling? i've been looking for one that will home over the touch pad, zero the tool, return to project, work, then return to touch pad for new tool ? or direct me to where i might find such a script .

[@Δημήτρης-η4ρ]

May i ask something?If i shutdown the pc, home my machine(i have home limit switches and it auto zeroes when they are triggered) will the offsets still there or they reset it all?

[@dougrundell947]

I'd love to see more videos on mach 3. I don't like the fact that I can only jog in one axis at a time. Is there a work around for that?

[@maxsmith2320]

Doug... there is a work around that.... just press up ARROW and right ARROW same time

Any thoughts of moving to mach4? I have a emco f1 running in demo mode (a gift). I am building programs that exceed the demo g code line limits. I am trying to decide if I should purchase mach3 or mach4.

[@alnaee2634]

Thanks for the informative vids . i have a weird problem with my Mach3 . All my axis works well only the positive , for example X+ and X- Y+ and Y- Z+ and Z- and A+ and A- . the negative movements do not work where do i go wrong in pin and ports? i appreciate any help here.

[@GuruBrew]

In ports and pins you should have shared a pin number between the negative and positive signal in most cases EXAMPLE (X++ and x-- should both be set to port 1, pin 10) Hope this helps

[@davordado9285]

beautiful and clear thanks a lot

[@arkanprivateinvestigator1642]

Nici and clear! Thank you!

[@Ronbrownsbest]

Thanks! I didn't see how I would go beyond the G58. I want to run the same subroutine every 16" x 16" on a 4x8 sheet. Any help?

[@scubasteve4486]

You might want to use a cad software to create a pattern then use sheetcam to write the g code for mach3.

[@NeoIsrafil]

Yah I've always wondered if there was a way for mach to tile a toolpath too rather than me making a different gcode for each length of wood I get, to just kick out like 8 signs in a row up a board.
