I'm new to the operation of CNC machines and am just setting up a machine that I have built. I wanted to have the AXIS and +/- directions setup so they made sense to me but I'm worried I am accidentally creating a rod for my own back somewhere down the track. I have changed the Jogging Screen Layout as per the image below.
The Z axis is my vertical axis that carries the spindle & the ++ is at the bottom of the axis. The axis is Homed to the top away from the ++.
The Y axis is the gantry (across the table) with the ++ on the right side (looking at the spindle) and it is Homed to the Right + side. I will probably Home to the other side once the cable drag chain is installed.
The X axis is along the table (who would have guessed
) with the ++ at the back of the table, I'll probably Home to the front (--) of the table so changing cutters will be easier.
All thought welcome, for what its worth negative numbers just confuse me.
