MACH 3 Z axis
« on: September 02, 2009, 05:33:57 AM »
i have manage to get Mach 3 up and running but when i cut a file the Z axis works in concussion with X and Y.
can i setup Z axis so that it will move on it own, or am i getting it wrong in lazycam .

If your code has a G0 or G1 move with X Y and Z moves all on the  same line then they will all move together. If the Z is on a seperate line then it will move alone, likewise X or Y on their own line.
So as an example if the code was as follows all axis would move together

G1 X100 Y 50 Z-10 F100

If however the code was as follows the axis would move one at a time.

G1 X100 F100
G1 Y50
G1Z-10

LazyCam should be putting out seperate Z moves if they are required. Afraid I dont use LC but a few here do and if you look in the members documents you will find a manual that Rich wrote.

Make sure your Z goes up first and down last: up out of the way before X and Y movements, especially rapids, and down after X and Y have put it in the right place. Sounds obvious but I snapped off several cutters learning that one.

Also make sure your feedrates for Z are specified explicitly to make sure you don't stub your cutter down too hard :)

dpot,
Can you post your .lcam file which is posting that code, as i am curious as to the code posted from LazyCam and you cut parameters set in LC as well.

dpot,
Took a quick look at what you posted.I suggest you take a look at the LazyCam manual.
Note that LC will default to a positive Z=1 for the rapids on import of the dxf.
How are you planning to cut out the parts of the plane? I think that the layout was meant to use a knife
to cut them out as there is only 2 mm between some of the lines.
Note that if you wanted to cut everything out all you have to do is select the layers you want to machine and define the cut parameters for  those layers. If not LOL, as the entities are scattered into diffferent layers.
Have Fun,
RICH
