Size Help

[Mark Stehr]

I am running Dolphin CAM V10 with Mach 3. I just got it along with a Sieg KX1.

The problem is z travel seems fine, but x-y seems tiny.

I believe it is all in metric, I've checked the settings in Mach 3 controller and in the Dolphin CAM. Every time I start CAM a window pops up with options including inch or metric. I always choose Metric, All my read outs are in metric in the controller. In CAM under set up>machine type> mill> it is set to metric.

In the Controller Mach 3, under General Logic Config The G20-G21 box is blank (unchecked) for _ LOCK DRO's to Setup Units. Should this be checked?

One funny thing is the diameter of the cutter changes once the program is loaded. I set the tool info in mach 3 to 6.37mm, and I also set the same info when writing the CAM program and it changes to 161.798mm??? I am using a template program to cut a simple rectangle pocket.

The only other thing I can think of that might be funny is that I have written the program in CAM, Post Processed it from Dolphin CAM so it is now a .ppr file, then I load it from the "My Documents" folder.

I've included pics of Regen and Tool Setting changes before and after the program is loaded. Am I right that it is cutting, but just really small?

Any help is truly appreciated.

Thanks,

Mark Stehr

Hello Mark,

I think that this is something in the MACH setup. 6.37 x 25.4 =161.798 which is the inch to metric multiplier.

Maybe because you don't have the G20/G21 switch set it is converting the tool sizes.

This wouldn't explain the small sizes, I don't enough about MACH to point you in the right direction.

Perhaps a post to the MACH forum would be useful.
