FAQs / Re: Cant get tool settings on mach3 to work... NEWBIE :)

« on: July 15, 2012, 04:06:45 AM »

Hi Rune,

There are different ways of handling the cutter radius compensation.
You can produce an 'on the line' type of toolpath then include the G41/G42 commands into your GCode to apply the offsets set up in your tool table etc (see the Mach3 manual for full details).

Personally I prefer to include the cutter radius compensation into the generated GCode (exactly what your Phlatscrip appears to have done).
Just changing the tool size within Mach3 will not have any effect on the actual toolpath if you are using this method.
If you post a question on the Phlatforum the guys there will will tell you how to set your tool diameter within the Phlatscript/Sketchup GCode generation.

G-Code, CAD, and CAM discussions / Re: CorelDraw PLT to Gcode

Hi FlatCreek,

Sounds as though the problem is in your SheetCam settings then.

Sorry I can't be of any help here as I have no knowledge of using SheetCam but there are many other forum members who use it all the time and I am sure they can help.

Hi FlatCreek,

Perhaps some more details of exactly what you are doing may be helpful in resolving the issue.

I presume you are exporting the Corel drawing as a PLT file then loading this into LazyCam to create the necessary GCode toolpath ??
If so then perhaps the problem is within your LazyCam setup.

Hi Abhi,

It occurs to me that any axis 'slump' you have would vary dependant upon tool loading and not just the axis position so the only realistic solution would be to change to fully supported rails despite the cost.

Just a thought.

And just to add to the suspense a pic of the blade holder fitted to its Sonotrode.

I needed a new blade holder for a tangential knife which would enable relatively quick and easy blade change and positional setups.

With just a couple of hours to spare, whilst another CNC job was running, this was the result (the only CNC operation was milling the flat).

Hi Terry,

The physical over travel clearance is 0.5mm before the top of a limit switch is contacted, there is then a little more as a switch is activated.
