I bought my M3 2.5 years ago and am just now able to use it again after sitting in a closet for 2 years.
That being said i am learning all over again and having some difficulty.
I designed something very basic in easel and exported the g code file, opened it in UGS platform and when i run it all of the axis go to max and try to keep going until i stop it.
Another problem i have is that the yellow arrow in UGS does not accurately portay where my spindle is, it just sits there as if im nit moving anything around.
i do have control of X, Y and Z manually.
When building the file in easel i set the size of the work piece to 10" square and i run the toolpath in easel and it works fine.
Since i hadn't used this thing in a couple years i did make a mistake this morning and fried the uno, i ordered full new electronics from Millright today but i had another uno laying around and put GRBL on it and got it running after i realized what i did wrong, i plugged the 24v into the uno.
Anyone have any suggestions? A lot of this stuff doesn't make sense to me but im catching up quickly.
Do you know why the yellow arrow in UGS is nto accurate to the placement of the spindle?
No matter what file i use the z axis goes to the top and then the y goes all the way forward (front of the machine) and the x goes all the way to the right and all axis bind up until i stop them.
Does your M3 have limit switches? If so, have you tried homing it in UGS using the Home button in the Common Actions window? It might also be labeled $H or you can just type in that command. That will set your machine zero position. From there you can jog the X,Y and Z to the zero position on your workpiece and hit reset zero to set your work coordinate origin. (Hopefully I got the terminology right.)
Based on what is going on it seems as though the machine thinks that it is bigger than it is.
When trying to run a file it goes to the back right corner, opposite of where i have home at.
It then tries to keep going, what i noticed is that the yellow arrow is moving but much slower than the x and y are.
I have made multiple files where the work area size is between 6 and 10".
Is there somewhere that i can tell the machine what the maximum size of the work area is? i thought this was done inside of the g code, you design something in the space given and the g code tells the machine to stay within this space, am i thinking about that correctly?
My 3d printer has a setting where yo u tell if the max x, y and z. Can i not do that with this?
EDIT- I let something run and it does all of its movement in the back right corner, this is what it does for everything i try to run.
I tried these settings earlier and it did all sorts of bad things.
X, y and z would only move about 10mm very slowly and my z motor would make a whining noise and got pretty hot. It would only stop when disconnecting the 24v power.
I was able to stop it by reverting to the settings I posted.

The back right corner is the default homing location.
The Steps/mm are very high at:
$100 = 250.000 (x, step/mm)
$101 = 250.000 (y, step/mm)
$102 = 250.000 (z, step/mm)
Should be:
$100=40.000 (x, step/mm)
$101=40.000 (y, step/mm)
$102=80.000 (z, step/mm)
Check the jumpers on the CNC Shield to make sure you have the right settings. (page 29 of the M3 manual.)

I agree with Bruce that you should take a look at your jumpers and make sure they are vertical as pictured in the assembly instructions versus horizontal.

It seems weird that your GRBL firmware settings were messed up. Did you by chance connect to the machine with Easel? If so, I believe Easel can rewrite your firmware settings, thinking it is an Xcarve. You should only use Easel to generate gcode, and then connect to your machine and run the gcode using UGS or another dedicated gcode sender app.

I did use Easel but i generated the g code. I did not let Easel make any changes.
