Title: Save Z - Beginner - To many options - Simple but not for me
Post by: jokerper on June 06, 2018, 08:21:36 AM
Hi

I have been generated some gcodes from Vetric where it demands the Save Z settings and Home start position x,y, z.

My autotool macro have also an save Z setting:

ZMove = 30.00 'Total lenght of Probe to move before Stop or no Contact Made.
ZOffset = 25.00 ' Plate Hight
ZSal = ZOffset + 2.00 '+ Free Hight, Will possition the Proble 2 MM over the Material.

Mach3 config also have a save Z setting.

So now am I confused.

How should the output be:
Vetric
Save Z = ?
z1 = Clearance = ?
z2 = Plunge = ?
Home start x=0,y=0,Z=?

Mach3
Config - should I also use the same save Z settings in here ?

In Mach3:
What should the DRO be at:
X=0
Y=0
Z=???

Hope you can help me...

You are not doing anything wrong you just need to give it more time - many do not visit the forum on a daily basis and many, like me, just don't have a definitive answer.

It is not "saVe Z" but "saFe Z".
In Vectric:
Z1 Clearance is height above material Zero (top of material) for rapid movement (G0) to avoid any clamping of your material.
Z2 Plunge is height above material to which your tool will be plunged at rapid speed (G0) before switching to programmed plunge speed (G1).

For Safe Z in Mach3, you should do some reading (Mach3 manual, no link at the moment).

And please, take look at the attached picture. If it does not make all clear, then sorry  ;D

If you have a Z axis Home switch, then in Mach3 I would set it to machine coordinates, and a small negative number, like -1.
If you don't have a Z home switch, then I would disable Safe Z in Mach3.

Can I ask you about the setting "Position model Gap above material" 1mm

I think I have been getting into some good settings now.

Code: [Select]
ZMove = 30,00 'Total længde af Probe at flytte før Stop eller ingen kontakt lavet.
ZOffset = 25,00 '
Pladhøjde ZSal = ZOffset + 2,00' + Gratis Højde, vil give den mulige 2 MM over materialet.

Mach3 config har også en gemt Z-indstilling.

Så nu er jeg forvirret.

Hvordan skal output være:
Vetric
Save Z =2
z1 = Clearance = 2
z2 = Stoppe =?
Startside x = 0, y = 0, Z =4

Mach3
Config - skal jeg også bruge de samme gemme Z indstillinger her?
I disabled Safe Z in mach3

I Mach3:
Hvad skal DRO være på:
X = 0
Y = 0
Z = 4

I think it works for me.

The surface of a wood that I've been cutting in 2.5D was uneven, and since there was a lot of material on the back side, the whole model was "sunk" for 1mm.
