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

Mark,
I think your problem with the tool size is caused by Mach starting in Imperial. When you load your Gcode which you generated in Metric, there will be a G21 - probably in the first line - and that switches Mach to Metric mode and multiplies all dimensions by 25.4, hence your 6.37 tool diameter changing to 161.798. I had similar problems to this when I started with my KX1 and had several peculiarities like yours working in metric. I saw that Mach always seemed to start in Imperial so I added a G21 entry to the initialisation string in General Config and now everything seems to work as I intended.
Jim.

Awesome thanks Jim!
I'll give that a try. Thanks for the help!
