General Mach Discussion / Mach 3 installation

« on: December 07, 2010, 12:12:11 PM »

Hi
I used my mill with a mach 2 program for a short time and now I installed the Mach 3 but I ran into some problems when installing...

First I copied all the settings from the mach2 (i think)
but now I wont get my mill to run? it seems to do the job on the screen but the mill doesnt move or turn?
I got all the limit switches runnining exept the emergency trigger? cant figure out why and if it has something to do with the machine not running...

And the mach 2 program wont run ether?

Any basic hints, any standard things that often are forgotten? Modbus settings??

I guess that its just one or two buttons to press...

Thanks

G-Code, CAD, and CAM discussions / HELP toolofset, G42

Hi I have made a simple drawing in SolidWorks and generated a G-code and I loaded it to my mill with Mach 2 system, but it will not accept my tool and then also not compensate for the tool, I have a tool in my tooltable 6mm diameter and in my mach window It says T6 but I am not sure if there is any ligt that should indicate that its active?
anyway, I thought that I could just change my G-code and get it right! BUT NO!

Sometimes it works a few posts in to the program, and the I get errors
for example : "Concave corner with cutter radius comp on line #23"

this is my code

This is just a 4 sided part with one big hole 50mm and two small holes, it turns out just fine exept the part is 6mm to small and the holes are 6mm to big, due to the cuttercompensation does not work....

I would be very glad if anyone gould explain what I do wrong?
and I can add that I tried to set up the Mach 3 program but I didnt get it to work, so that is not an option at the moment, but I guess that the mach 2 should work...

G-Code, CAD, and CAM discussions / DXF-Mach2-Scale

« on: November 23, 2010, 12:45:45 PM »

Hi everyone, Iam new to this CNC programming but I have made good progress...
I am blaming my poor english combined with how-to-do manuals I have got stuck in my milling when I tried to import a SW-drawing to my Mach2 program

I dont know if I do anything the right way but this how I do it: I sed my SW-drawing to the SW DWGenerator and remove all the templet lines from the SW-drawing? then save the drawing as a DXF and after that I import the file into the Mach2 "import DXF"
So far so good i get G-code and everyting looks fine, but when I start my mill, the part turns out much bigger???

and also I cant get the toolradius to work but thats an other story (perhaps i just need to find an example to follow)

I would be glad if anyone could help me.

I´m from Sweden that is my exuse for poor spelling and bad sentences
