Can anybody help me write a post for a Techno-Isel RG-5996 Servo Driven unit? I have used SheetCAM quite a bit with my Tormach Mill and would like to use it to get started with my recently acquired router. I have never made a custom post before and I don't have any known good nc programs for the machine.

Where can I start?

After posting the first part I remembered some of the demo files that are included with the machine:

Try the 'minimum g-code' post. If arcs come out strange, try 'minimum g code abs arcs'

[68rustang]

I have my post processor set as 'minimum g-code' as suggested. Does SheetCAM only output *.tap files? The Techno controller looks for *.nc Files. I changed the file extension to *.nc manually and when I loaded that file the machine didn't move as expected.

Basically it went to the tool stand location and picked up a tool, then instead of moving down to the surface and starting the cut it went up and hit the limit switch.

Looking at the code,to my untrained eye, the only difference I see is the supplied demo files don't include line numbers.


This is what it produced:

My experience thus far has been with SheetCAM and my Tormach mill with hardly any issue.

To change the output file extension, go to Options->G-code file extension.

Try removing the line numbers and changing the G20 to G90.

If it works, I'll make up a post to suit.

I changed the G20 to G90 and it seems to have worked. I left the line numbers in because I was too lazy to manually edit all the lines.

I ran a program cutting air and it looked good.

Les,

Another thing I have noticed is it is not setting the spindle speed. It is only turning it on or off. Can that be accomodated in the post you offered to write?


Thanks,
Eric

You can change the post yourself if you want. Go to C:\Program Files\SheetCam\Posts and make a copy of the post. Open the copy with a text editor such as Notepad. Near the beginning of the file look for this line:

-- text (" G40 G90\n F1\n")

Change it to:
text (" G90\n")

Save the post. Select this post in SheetCam and try the code. If the router still gets upset, edit the post and delete these lines:
if(scale == metric) then
text (" G21\n") --metric mode
else
text (" G20\n") --inch mode
end
