Mach3: How to Set (Zero) Milling Tools and Edge Find Workpiece

How to set tool length offsets and work offsets for a Mach3 milling machine CNC conversion.

Love the idea of G59 as a std location to check/create your tool height offsets.
Nice job!

When you are close to the surface, just release the tool from the tool holder, lower it to the surface, and tighten it again.

Well done! I'm saving this to my favorites.

Another great vid! Thank you! Very helpful. :)

hi great help, I got in trouble with the tool offset, I have put the tool Nr 1 a 4mm finish EM and by the hight a dummy nr as you did but the tool offsets button is off, please help.

At the minute 5:01 how did you paste the comand on the input and then what command did you pulse to crank the spindle down. Thank you

great video its not letting me set the bit and the green light dosnt come on
any help

if you dont touch off the head without a tool how can you get a tool measurement..?

Hello, what are the conditions that must be available in the computer in order for the Mash3 usb to work with me without problems, and thank you very much

When you Jog down in MPG one step 0.001" do you press, and will move continually or just no matter how much you pressed it you will get 0.001. Because my system moves more than 0.001" when you press it, what I'm doing wrong?

Great video, I just have a question on the x and y axis offset. The mill tool Dia is .3125 inch and the Gage block or shim is .005 inch. I was wondering why did you double the thickness of the gage to .01 in and the total dia is .3225 inch. I was think only one side on the cutting edge of the tool is contact with the surface of the block so you just have to add .3125 and .005 and the result is .3175 inches. if the off set is .3225 inch would it be too far from the block that is needed to be milled?

Is there any point in doing this if you are just using r8 collets instead of repeatable tool holders?

[gokhanceterez]

we assume that clamp is perfectly parallel to the axis, right ?

Hi Frank, thanks for a great educational video, I have a question regarding on tool length measurement using G59, so when you change tool for a different operation, do you always have to reset the G59 tool off set and new tool length measurement must be made? because I am working on this one milling project and it requires few operations with different mill end bits and length. Thanks in advance

How about a mechanical edge finder?...they're cheap as not to use one, and much better than using a rotating mill and a paper.

Hi Franco i am not understanding the G59, is this just a reference for positioning for G54? Thanks, Great Video!

do you know what to move in the mach to get off the switched on limit switch?

[OrganGrinderEleven]

OK, I get that you like the feel of the shim as an edge finder, but DON'T do this with gloves on! even though those nitrile gloves are pretty flimsy, it's just a bad practice to have gloves anywhere near rotating parts. That mill would be happy to rip a finger off. I've seen it happen.

Your x and y home positions are backwards.

I clicked on video to see how to bring it on origin zero but no info
