Thread: Homing.....totally confused

Hi all,

I'm having some trouble understanding the homing/limits setup. My BIG problem, is trying to figure out where X0Y0 is supposed to be (specific to a gantry router).

If I stand at the front of my machine (as per picture), I was trying to set X0Y0 to the top left corner. I can set this up okay, and the DROs all work correctly. However, when I set a work offset (G54), Mach seems to want it's X0Y0 at the bottom left corner of the work. When I do this, +Y goes in the right direction, but +X goes the wrong way. So if you load the Roadrunner, the tool comes off the work when it traverses X. Am I supposed to be setting home at bottom left?

If someone with a gantry machine can explain, it would probably help me save some of the little hair that I have left. A screenshot of your homing/limit screen would be very nice too.

I went onto the Vectric site today, to purchase Cut2D. They are using an exchange rate of 0.56, compared with current 0.669. I tried to order in US$, as Paypal is using the correct exchange rate, but they are still trying to bill me in AU$. This adds AU$43 to the cost . I've sent them an email, and hope they will fix the issue before I continue with the purchase. I haven't found an alternative site to purchase from, so I might be stuck with a crap rate when I buy.

Thanks for any help.
