General Mach Discussion / Re: Mach3 & Artcam ramping problems

What is in the height offset 1, it should have zero in the Z height.

or

Remove the lines N30 & N40 to kill the offsets.

Tangent Corner / Re: DYI Rapid Prototyping

The very early ones used paper, they rolled glue, then laid paper on top, then cut the shape out with a laser, they did this over and over again until the final shape was complete.  They also had the advantage they could make hollow shapes without supports, funny how things move on, not always for the better.

General Mach Discussion / Re: Mastercam X Lathe Post Processor

Some posts do a G97 to stop the spindle accelerating as the x axis rapids into position and then change to the G96 to do the cutting, sometimes they do it on a rapid to a tool change as well.  The G97 fixes the speed at what ever it is at the time.

Send me the post and I will sort it for you.

It looks like a setting problem to me, the code looks OK, a few funny bits in it but nothing that's going to cause a problem.

This is what its doing on each line so you can see if that's what it dose on the machine.

General Mach Discussion / Re: Why don't work simulation offline?????Grren pen not showed

« on: February 07, 2007, 02:16:30 PM »

Remove Mach3 and reinstall it, run it with the default setting and it should run the simulation with out any problems.

DON'T install the mach drivers when you are asked.

By the way, the demo version will only run the first 1000 lines of the roadrunner.

General Mach Discussion / Re: Drawing / engraving size difference

Hi fred,

can you export DXF from your drawing package.

I think HPGL is scaled to fit on your printer page, you may have an option to export in 1:1 scale this may cure your problem.

It sounds more like the DXF file is metric
