size help

[Mark Stehr]

I am running mach 3 and dolphin v10 on my new Seig KX1 and I am programming in MM and the mill is in MM. z axis seems fine, but x and y jog fine. but when I run the program or run the regen on the control everything seems tiny. I run the part and it looks like its not moving.

Any ideas?

What are you're default units set to?

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?

I can't thank you enough, thanks again so much.

Kind regards,

The .ppr file is Dolphin's post processor file. It seems as though you may be confused a bit. I assume you are posting with the correct post, mach3_inc.ppr?

The G20 in the upper right of the first pic tells me the machine is set up in inches. When you load the g-code with a G21. it's multiplying the diameter by 25.4, thinking it's displaying in mm's.

Or the other way around.
You're definitely mixing units.

I'm guessing the machine is set up in inches, and the g-code is in inches, but with a G21 in it.
