Hello, I am building a 6ft x 11ft plasma water table. Table is mostly completed. Using Masso controller. I am very new at this and learning from scratch. I have the homing set at Z0,X0,Y0. Everything goes to the back left corner. From there my coordinates goes X 0-120", Y 0-64", Z all the way up, 0-4" Is this right? Or do I need to splite the distance and have  Orgin in the center with negative at on end? Meaning my home would look something look X -60 Y -32, Z 2.
I uploaded a picture. Any help be appreciated.

not realy, normal it you are in front of your table:

x to the right is positive
y forward is positive
z up is positive

have a look (describes the right Hand rule):

Hmm, so you saying I have X and Y backwards?

if the left side off your Picture is the front side of your machine,
then y is backward, and z as well.

My front is at the end.

that is not "normal",

because all drawings have this orientation


 Y+
 |
 |-----X+

so you allways have to "rotate" in your head.

So, I do have my X axis and Y axis backwards?

Yur Home position should be towards your bottom-left.Looking at your photo/drawing Your Y should be X, and your X should be Y

Yes, it's backwards, but you don't have to change it.


If you set your Y home to be 64, then it's fine like that. Just set the Y Home Offset to 64, and Y 0 will be at the other side. And moving in the correct direction.

Thank you very much. That explains the issues I been having in Sheetcam. I will change it, it will drive me nuts every time I look at it. Thanks again for everyone who took time to help me out.
