Hi there,

I'm brand new to cnc machines and got my hands on a dyna 1000 24x36 with mach3. I got a brief run down from the previous owner but now I'm on my own and reading up like mad

I can't seem to get my z axis to return to zero. I can move all three axis but when I press GoTo Zero only the x and y return. Am I missing something simple in the settings?

Any advice would be appreciated!

Thank you,
Tony

When you use Goto Zero, the X and Y axis move first, then the Z axis.

Is the Z axis enabled and working?

All axis work if I move then using mach3 with the arrows but when I use the goto zero function only x and y return and the z stays to wherever manually adjusted it to.

Cheers

What version of Mach3? You might want to try reinstalling Mach3, or trying a newer version.
DO you have a valid license?
Check through General Config, and see if there is a setting for Goto Zero. Also check in Config > Safe Z.

I do have a valid license. Note at the shop right now but I'll check the version of mach3 in a bit and update if needed.

Let you know!

I just took a look, and I don't see any settings that can cause what you're seeing.

Gerry,

Is it possible that the home offset was manipulated?

Jeff...

[ger21]

Goto Zero goes to work coordinate zeroes. Home Offset just changes the machine coordinate home switch position, and should only affect Homing.
I don't think that it would have anything to do with Goto Zero.

I'm running Mach3 R3.042.020

I've also attached images of my Safe_Z settings and Motor Home / Soft Limits settings.

Also, just so you guys knows..... My Z axis is working and I can run simple test files that I've setup. I've created just a triangle and messed with pockets using lazycam. Its basic for you guys but new for me The thing that I don't get is that the z axis is working and run files, but pressing GoTo Zero only returns the X and Y axis back to their zero's. I know that you can customize the screens / buttons in Mach3 so is it possible that previous owner messed with the actual function of the button on the screen? How would I go about checking that?

Cheers,
Tony

You'd need to open the screen .set file in a screen editor to check the button function.
Is there any message displayed when you press the Goto Zero button?

I think I have that version on my machine, but I never use Goto Zero. I can't check it because my machine is buried under a pile of junk right now.

I'll download a screen editor and see if I can figure out the function of the button! My machine has homing sensors (limit switches I think) but they don't seem to be working right now otherwise I would use them to home to the bottom left corner of the table. Thats another project along with ensuring the machine is square I did some pocketing on triangles and one side of the triangle is slightly thicker than the other but the depth that the z axis goes down is consistent when it routes out the entire inside.

Sorry if i'm not using the correct terms for these functions / processes. I'm green but learning quick!
