Thank you for your replies...

1) The problem is that when i use cv all the time when i draw circles these don't have smooth lines but rather have many many small steps.

2) Well, i will be as descriptive as i can...
We have the motor with the head for the tool change, and when you are in front of the machine you see the disc motor that is on the left of the router motor. This motor has the ability to change directions, and i mean by that that it can align to disc to cut along X or along Y. The point is how i can find the center of the cutting disc related to the router as some times disc will have to continue a job where the router was and vice versa, and of course how to make this be done automatically.

3) I probably did not explain it well, when i say the main console i do not mean the main mach3 screen, but the control panel that has the various switches on that control the machine.

4) Explored that folder and opened the files it included but did not find anything relevant to homing... Looked at Mac3/macros/Mach3Mill

5) ...

Regards,
Tom Stefanou.

Thank you very much for your rapid replies but still have soe questions...

1) How does it know when to use G61 or G64?
2) I am using SheetCAM
3) Is this a setting in Mach3?
4) If i got it right i just have to enable Safe Z option?
5) I have 9 tools that will be placed in the same position after they are used... so the real question was how to instruct mach to get each time the correct tool from the right position and furthermore how do i set up all these tools?

Thanks again,
Tom Stefanou.

Hello, my name is tom stefanou, i have a 3 axis cnc machine.

i would like to ask a few things...

1) How can i instruct the post processor or somehow else switch to Constant Velocity when it draws a circle and to exact stop when it draws a rectangle?

2) The cnc machine has a router and a a cutting disc. The disc can operate in 2 directions. along X and along Y. How can i calculate and implement in the post processor the offsets required for the cutting to be correct and accurate?

3) I want to enable the router through a Start button on the main console. In case the router is not enabled i don't want to allow the user to start the code execution and also warn the user. Is there a way and if yes, how ?

4) I want to have a button that will find home position of all axes. first of Z then of X,Y. The point is that i want Z init to complete and then to start X,Y homing. I found the Command G28.1 Z1 and then G28.1 X1 Y1 but i want to insert a delay between them. How could i do that?.

5) I would like to make use of the tool changing functions using the atc post, the tools have fixed positions. i don't know how to do that at all.

Thank you all in advance for your help.

P.S Sorry for my bad english!.

Tom Stefanou.
