If you are in absolute mode entering "G1 X1" tells Mach3 to move the X axis
to the position where X=1". If you were at X=9 or X=-7 then the machine
would have to move the X axis 8 inches to get to X=1. If you are in
incremental mode and enter "G1 X1" you will move 1" in the positive
direction from where you are now. Think of it like standing in line, you can
move to the front of the line or back of the line (these are absolute mode)
or you can move up or back one position (incremental mode).

I enter G1 X1 into the midi and my X axis moves exactly 8". Can anyone tell
me why the DRO reads 1". Thank you Art

I've never had homing switches, and always simply zeroed the DRO's to set a new
'home' position. All the machines I've supplied work the same way, and we
simplified the screen layout so that the key tab 1, 2 and 3 functions are on a
single page ... load, zero, run ... what am I missing?

If a system has no homing switches turned on, then Mach will zero the machine coords when home is pressed or called for

Message 13 of 17 , Aug 20 7:45 AM
• 0 Attachment
You're missing the difference between 'machine' coordinates and 'local'
coordinates. Let's say you have a 4'x8' workbench. You have a board that is
1'x2' that you want to drill a hole in the middle of. So, you pick up the
board, place it on your workbench, use a tape measure to locate the hole's
position from the edge of the board and proceeded to drill the hole. This is
perfectly natural to us as we instinctively understand where the workbench
is, where we placed the board on the bench and that we need to measure from
the edges of the board to locate the hole, we would not measure from the
edges of the bench.

Machine coordinates describe a location on your bench, local coordinates
describe a location on your piece of wood. You can move your piece of wood
anywhere on the bench and your local coordinates on the piece of wood
remain the same.

Now picture you have a 4'x8' router table instead. Machines are stupid and
can't 'see' the ends of their travel like you and I can. So you might want
to tell the controller that the machine travel is limited to the 4'x8' area.
That area the machine can move in is described in machine coordinates, i.e.
it can start at the front left corner which is (0',0') and travel to the
back right corner which is (8',4'). What if you wanted your spindle to raise
all the way up after a job was completed? When you put the board on the
router you set Z=0 to the top of the board right? Yes, but that was the
'local' coordinate system of the board. If you tell the Z axis to go to 0.00
in local coordinates it will take the bit to the top of the board, if you
tell it to go to Z=0.00 in machine coordinates it will raise the spindle all
the way up.

While these different coordinate system seem confusing and even unnecessary
at first it is important to note that we instinctively use them all the
time. If I asked you to set the board on the router table 6" in from the
left hand side and 6" up from the bottom edge that would make perfect sense
(machine coordinates). If I then asked you to make a spot 6" from the top of
the board and 6" from the right hand side of the board that would make
perfect sense as well (local coordinates.)

Hope that helps,

Jeff Birt
