Title: Wrong working order when offsets used
Post by: Carel_cnc on September 17, 2006, 10:43:18 AM
To all,
When i start a job in Mach3 and use an offset (e.g. x-50, y-50, z+10) the program starts by lowering first the Z-axes and then it moves the X and Y axis.
To my view this is the wrong order because now the bit can run into the clamps that are holding the workpiece.

Am i doing something wrong, or is there a setting to make the program first run to the x,y coordinates and then lowering the Z-axis and if so where is it.

All help is appreciated,

Greetings Carel_CNC

Carel,

Take a look at the safe_z postion option under the config. logic menu.
See using Mach3mill documentation for it's use.
What are the first few lines of your program?

I agree with allanjs, using the Safe Z would fix your problem but, what/who made your G-Code?

If somebody actually wrote the code, why not just edit the code so the Z command happens after the X & Y travel to the proper position.  Or, if the code was generated by Lazy cam, I think you need to set the rapid Z depth so it won't hit your part.

Good Luck.
