Thank you TPS :)
Now is much better, but still is problem with Z.
After fixing all parameters for correct directions XYZ in MPG MODE and now HOME working correct too, but after pressing GOTO ZERO my X and Y going correct, but Z going UP... and my Gcode is over Machine Boudaries.
Do you know how  to solve this problem?

Do you know what values should to be fixed for A Axis in HOME limits?
I would like to use Helical Interpolation for G-codes.

By the way, I have licenses from 10 years and I still using in the first machine, but everything have been set up automatically by loading Puling and now I see other options for setting all.

for your z-axis up is positve and down is negative?

goto to Zero means goto Zero whereever you set the Zero of your z-axis
if the actual Position is negativ it will go up if it is positve it will go down.
anything is possible, just try to do it.
if you find some mistakes, in my bad bavarian english,they are yours.

are you still talking about this g-code ?:

Code: [Select]
N100G00G21G17G90G40G49G80
N110G71G91.1
N120T1M06
N130 (End Mill {3 mm})
N140G00G43Z15.000H1
N150S12000M03
N160
N170()
N180G94
N190X0.000Y0.000F2000.0
N200G00X-23.500Y-23.500Z10.000
N210G1X-23.500Y-23.500Z-1.000F500.0
N220G1X23.500Y-23.500Z-1.000F2000.0
N230G1X23.500Y23.500Z-1.000
N240G1X-23.500Y23.500Z-1.000
N250G1X-23.500Y-23.500Z-1.000
N260G00X-23.500Y-23.500Z10.000
N270G00Z15.000
N280G00X0.000Y0.000
N290M09
N300M30
%

here
N200 G00 X-23.500 Y-23.500 Z10.000
the g-code tells machine goto X-23.500
so if your left bouandary is X0 then it whants to go outside.


as sayed before, to run this code jog your machine somewhere to the Center of bed and lower Z-axis aprox 15mm

then press X-Zero and Y-Zero and z-Zero and THEN run the code

Hi,

I have to say true, that correct position of Gcode for inside Machine Boundaries were saved only after turn of Mach3 and PC too.
After next opening Mach3 were correct position of Gcode.
The same situation were after setting Z and position of Gcode.
That explain why I have had so much problem with setting all parameters.
For correct Save Setting don't enough just push buttons and confirm by Save Setting.
For totally saving parameter we have to turn off Mach3 and reset PC too.
After such operation are 100% saving Settings only.!
About such saving told me the expert who sold me the Mach 3 program, but I forgot about it.

Now Gcode position of Z is inside Machine Boundaries ofc.

"for your z-axis up is positive and down is negative?"
Yes , but after HOME I have X and Y in minus value, and Z in plus value.
Is it correct?

Maybe you know how to setting Gcode for Axis, because I dont see correct G code after GOTO ZERO.
Now Gcode looks like I attached.
Two option when  ToolPath / A-Rotations Enabled is active and without active A-Rotations Enabled.
and General Cofnig.

What is wrong?

sorry never used a 4th axis.
there are some setting's in Config -> Toolpath maybe one those help's.
anything is possible, just try to do it.

OK TPS
Thank you very much for your support :)
I have one more question,  what should be  the value of the Z axis  in the minus or in the plus after HOME?
I showing it above... on my screen.

that depends on witch coorinats you have selected (machine coords or workpiece coords) with the button below
axis DRO's.
in machine coords it is normaly Zero or a small amount in minus
in workpiece coords it depends where you set the workpiece Zero, but normaly it will be positive.

just try it by set Z-Zero somewhere below upper end of Z-Axis then make a homing and the press the
Machine coords button to toggle the cordinate System.
anything is possible, just try to do it.

Yes I make like that.. and have result like above.
Maybe my English isnt so good for technical explanation...

Could you check your HOME value XYZ and comparing with my screen ?
I dont have other router for such comparing.

makes no sence to do a test on an other machine, coord's will allways be different.

Looks like you haven't read the suggested chapter of manaul about coords, Offsets and so on.

if you do a ref All, ONLY machine coord's will be zeroed and work coordinates will Display a value based on this
Zero and the actual work offstet.

go to diagnostic page, in the upper aeria all coords and offset's are displayed, Play arround with zeroing AND homing
and watch the values, maybe this helps to understand, why current Position can be differnt after homing.

anything is possible, just try to do it.
