I recently asked for a function in MachX to set the type of motion for any axis, moving-tool or moving-work but got nothing. A "normal" configuration is assumed, but gives no allowance for different machines.
So. Does X axis move the tool or move the work? Moving tool means left is Zero, --, and Home. Right is + and ++. Moving work means right is Zero, --, and Home. Left is + and ++.
Does Y axis move the tool or move the work? Moving tool means to the front is Zero, --, and Home. Moving work means Front is Home, +, and ++. To the back is - and --.
Z axis is usually moving tool, so Up means Home, + and ++, and Down means - and --.
In general, ++ means + end Limit switch, -- means - end Limit switch.
- and + are for coordinate system and DRO increment, which makes the tool-path display orientation correct. X increment to the right, Y increment to the rear, and Z increment upward.
If I have stated this incorrectly, please correct it.
