xyz orientation issue

[m_c]

As A_Camera says, convention standing in front of the machine, is X is right to left, with Y being forward/backwards, which typically means the longest axis is X. However on routers, it can be either, and I wouldn't say any particular way is right or wrong, as long as you know which is which.

Moving X or Y in the positive direction should move the spindle in the positive direction for the cartesian coordinate system relative to the work area, with the origin being in the bottom left (same as the home point on your top diagram).
So standing in front of the machine, on a moving gantry/spindle machine (aka a typical router), the head would move away from you/right for positive moves, or with a moving table (aka a typical mill) the table would move left/towards you.

If that is working correctly, then it sounds like Aspire is flipping the g-code for some reason. It's usually worth running one of the supplied controller example g-code files to see if things are moving in the correct direction (the classic Mach 3 test is the roadrunner file, which should be in the mach3 installation directory somewhere - strap a pen to your spindle, tape a bit paper to the bed, and see what happens).


It's worth noting the home point is actually irrelevant in terms of movement. Mach can be programmed so the home point is in whatever location you'd like. You could have it bang in the middle of the bed if you want, but it's far more useful to have it at a back corner to keep the spindle/gantry out the way for loading.
