I cut up to 16mm (0.62")
After it the cut turns bad, but I have cutted 20mm.
Normally I get better results if I use a constant speed, but as you say in corners the botton stays behind of the top as thickness grows. Normally I lower the speed of cut of all the piece (all the gcode) not only in corners, if you get behind in corners then it means that you are getting behind in the rest of the cut, but for example, you do not notice it because you are on a straight line.

General Mach Discussion / Re: Open door as pause
« on: September 11, 2008, 11:47:22 AM »
Thanks Hood.

I made a simple tap:

M03 S400
G01 X500 F10

When I press feedhold, the spindle maintains rotating, but X stop, if I pressed cycle start again, X moves, from the point it has stopped. It is how I would like, expect the spindle does not stop - very important. Appears that the spindle is "not connected" to the button.
What can I do ?

Thank you

General Mach Discussion / Re: dxf files for Turn
« on: September 11, 2008, 09:29:14 AM »
I do not use Autocad, but you should save the output in autocad for old compatibility, like R12 or something.
New autocad versions make dxf with more complex, and probably that is confusing lazycam.
Try qcad, is free.

Hi

I cut with plasma, and I want constant speed - better cuts. All other cuts should also be better with constant speed (laser,water ...).
Can you tell why do you want so slow down ?

Thanks

I use Qcad. For me a very good cad program that outputs standard dxf.
Lazycam opens it, in am not sure if lazyturn can do it, but the bases are the same so it should also (I never tried it).

General Mach Discussion / Open door as pause
« on: September 11, 2008, 07:12:55 AM »
Hello to all.

I have a complete closed machine, were if I open its door, the program should act like a pause: turning off the rotation of the spindle, shutdown the coolant. This allows the user to inspect the work. After the door is closed, the program continues doing what it was doing (turns the spindle on, allows a accelaration time, then continues)
I do not know if this is possible. I think it is, but also some security issues are present. Anybody did something like this ? It should be common.

My second question is how can I save my current machine coordenates, tool number and tool offset being used, so that when I open Mach again, everthing will be as when I closed it.

Thank you in advance,
Filipe

From what I am aware of, compensation is not fully functional in Mach3, at least in turn mode.
Do you use turn mode (lathe) with compensation ?

Thanks

G-Code, CAD, and CAM discussions / Software for process compensation moves
« on: September 04, 2008, 02:50:49 AM »
Hello.

I am looking for a software for lathe turning that would have:

1) for input a gcode file with compensated moves (that uses G41 G42 ....), for example the output of a mastercam software
2) that outputs the resulting moves without compensation that could be used in mach, since mach does not process the G41 and G42

Any ideias ?
Thank you

Show"N"Tell ( Your Machines) / Re: Prototype Lathe Toolchanger
« on: May 24, 2008, 07:36:50 AM »
Very nice toolchanger.

I also made a toolchanger some time ago, but insted of calling T0101 or T0202 and so one, I call a sub program in my gcode program that unlocks the disk, moves the dish to a determined position angular position (axis A in my case), calls a rely to lock the disk. All this code lines appear on the Gcode file that I upload to mach.

To make it more user friendly it is more nice only to call T0101, and the machine does all the rest, like it is shown on the video, and like all machines.
I really do not have an idea how this is done. For sure it have to be programmed, but were it is programmed ?

Thank you,

LazyCam (Beta) / Post Processor to change output
« on: April 02, 2008, 04:40:53 AM »
Hi to all.

I need to change the output of lazycam, for exemple from

G2 X12 Y435 I34 J546
G1 Y234

to

G3 X12 Z435 I34 K546
G1 Z234

this is for transform the active plane XY (that lazycam posts to) to XZ.
Is this possible with lazycam post processor method, or I must make ascript to do it ?

Thank you,
Filipe
