G-Code, CAD, and CAM discussions / Zero CAD to CAM
« on: December 19, 2014, 04:26:25 AM »
I am trying to use Mach 3 to plot from a dxf file onto ply. As I have limited travel relative to the job size I am splitting the job into 4 segments and plotting 4 times moving the job each time within the machine travel area.
Its obviously necessary to get the 0-0 point correct for each segment  ie TR, BR, TL & BL

I thought this would be easy. I am using AutoCAD LT then LazyCAM to generate the G code.
The process works fine except for the zero problem.

As a trial, I have just created a 50mm dia circle with the centre at 0-0 on the dwg.
When this is processed and then loaded to Mach 3 the 0-0 point is not in the centre. It is at the corner of a rectangle of the dia size.
Why does it not carry over the 0-0 point from the drawing ?
What do I need to do to achieve this ?

Thanks Geoff

General Mach Discussion / Re: Toolpath Display Reversal

Gerry,
My table X+ & Y + are to the right and away from me which I understand is the normal. I have a big diagram on the machine to remind me !!

However, the tool path is mirrored. My current job has an aerofoil section where the leading edge is on the left for the model.
It is on the left in the CAM program and is on the left in the Mach 3 toolpath. When the G code is run the machined cavity has the leading edge on the right.

General Mach Discussion / Toolpath Display Reversal
« on: April 11, 2014, 04:59:02 AM »
Currently my job/table is reversed compared with the toolpath display.
I do not want to reverse the X & Y movements.
I wonder if there is a way of just flipping the toolpath display >

On my PC (Windows 7 64 bit) I also have XP running as a virtual computer.
I have just tried the procedure suggested and it works fine, so I guess it's related to Windows7 and 64bit in some way.

My problem is thus solved as I can work on the XP version.

Thanks for your help.

I have tried to reinstall Mach 3, but get "Launcher Error Box showing - Could not start set up"

I tried deleting Lazycam and then installing Mach 3, but got the same message.

Hi Rich,
Do I have to reinstall Mach 3 then ?
I have tried deleting Lazycam and reinstalling but I did not get the prompt you mention.

General Mach Discussion / Mach 3 and LazyCAM

I am aware that Lazycam is no longer supported, but find it useful for simple profiles.
I recently had to reload Mach 3 and Lazycam and they are both accessible on the PC

However, when in Mach3 I cannot access Lazycam as I have previously ie File - Lazycam.
I just get "File not found"

Is there some linking action I need to take. ?

Thanks
