Hey

Well just to make life more difficult, we have version 1.84 of mach3 and in the config dropdown there is no referance to safe z setup....and in the material setup in artcam theres no option to have a top offset but i had a thought last night, would it have anything to do with the tool start depth for example it starts at 0 and tool finishes the cut at -5 so somewhere its got to go from 0 to -5 and in a slot 8mm long i guess it will have to ramp down to do this (maybe its a numb thought but !!!)

Cheers

If i remember correctly for version 1.84 you will find your safe z height on the diagnostic's page
Your problem has to be in your material set up as Brett said.
when you look at your g-code
N60 G00X0.0Y0.0    - moves to x & Y zero but not Z
N70 G00 Z10.0        - moves to +10mm in Z
N80 G0X27.5Y207.2Z2.0     - at the same time moves to this position while moving tothe +10mm Z and this is where it appears to give you the ramping cut you don't want.

If the +10mm is in your material then you didn't zero to the top of material or if zeroed from the top of table you have an offset in your mateial set up

hope that's a little clearer than mud, call your Artcam rep he sholuld be able to walk you through this one

The mateial set up page Brett posted is in AC pro but you should have one similar in Insigna

Hello to all,
I got a similar problem and don't have a clue also,when a file is loaded to Mach every thing looks good except at the start the Z axis goes up about 3-4 "  and comes back about 1" and starts to cut air and is no where close to the top of the material,I have to adjust manually to get it to cut but is not accurate.I check the Zsafe move and looks fine.Any ideas? Thank You for the help,Marco.

If everything looks good in your file then I have to ask if are you zeroing your Z axis before running the file? what is your safe Z height set to?
You might post the first few lines of your code.

It looks like a setting problem to me, the code looks OK, a few funny bits in it but nothing that's going to cause a problem.

This is what its doing on each line so you can see if that's what it dose on the machine.

Hello Gary,
I  do a reference of all of the axis and after that go to the edge of the material and zero all of the axis, My Z safe is set at .2

When you are in Artcam you should have an option of where you set you zeros. I susspect you are ref, off of the bottom of you material rater than the top.

hello to all,
No I check that part and the Z axis is set at the top of the material.
Thank You,Marco.

What is in the height offset 1, it should have zero in the Z height.

or

Remove the lines N30 & N40 to kill the offsets.

Graham,
I believe your referencing the file posted by Plastic4 and not Marco (rem300wm)
Marco post your file and I'm sure someone will be able to help you further if we can see the code to help trouble shoot.
