Show"N"Tell ( Your Machines) / 3D polyuretane special cutter

« on: January 04, 2008, 03:48:42 PM »

Hi.

This is my newest work, and also the most demanding work that I ever done.

It is a 3 axis machine to cut large blocks of polyurethane with strips of wood. My client will use this machine primary to make surf blanks.
Some facts: around 30 rollers, 7Kw including vacuum pump and cleaner.

It is tested and working fine. We are only doing a cage around all the machine to maintain a safety perimeter.

It was all designed in my workshop, in south Portugal.

I am accepting orders

General Mach Discussion / Control jogging speed

« on: October 31, 2007, 05:28:59 AM »

Hi.

This is probably very, very simple. I would like to control my jogging speed (keyboard), where (if I can) control this ?
The best would be to have 2 or 3 speeds, like using shift and directions keys to toggle between speeds.

Thanks

General Mach Discussion / XZ plane arc bug ?

« on: February 07, 2007, 04:11:35 PM »

Hello I started a topic with a similar name in lazycam, one day ago, but I think that the problem is not lazycam, but mach3.

If this is a bug, it is a big one. I hope I am doing nothing wrong because I am not a long time user.

I attached a very small Gcode (around ten lines). This code works very well if a user uses the XY plane. I am using the XZ plane, and the gcode is allready prepared for that, so if anyone wants to test is, nothing is needed to change in the config of the machine, you only need to load the code.

The problem is the directions of the arcs. G2 and G3 codes are not being interpreted correctly by mach3. Some arcs are being done CW when they should be the way around. This can be seen in the toolpath window.

As can be seen on the picture that I send, some arcs are OK, others do not. For an example, if you check the gcode line that appears on the window of the code (N70) it refers to a G2 code. What we can see on the toolpath is a G3 code!

LazyCam (Beta) / Lazycam arcs output bug ?

« on: February 06, 2007, 04:16:39 AM »

Hello.

I think this is a bug in Lazycam. I have a DXF file that loads just fine. It is only 2 lines and 3 or 4 arcs.
When it outputs the gcode, lines are fine, but arcs are not done currectly (start and end point seens ok, but the dirrection is incorrect).
This can be seen on the toolpath screen of mach3, so it is nothing to do with the machine that I am running.

I attached the dxf and the tap file.

Thank you

G-Code, CAD, and CAM discussions / Most simple Gcode with arc problem.

« on: February 05, 2007, 07:31:58 AM »

Hello. I'm running the latest version of Mach3.

I have in Config/General Config set to absolute mode and IJ to incremental. The following GCode gives me problems:

G17
G21
M04
G01 X30  Y20  F200
G03 X300 Y200 I60 J34  ; <------ PROBLEM
M05
M30

It gives me: "Radius to end of arc differs from radius ..."

I added G90, G91, changed the setup to absolute IJ and everthing else I could remember ...

Thank you.
