##### Help with table coordinates.
« on: December 29, 2018, 12:41:01 PM »

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

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

Make no mistake between my personality and my attitude.
My personality is who I am.
My attitude depends on who you are.

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.
