DXF files

[mmjpotter]

Hi everybody,

I am looking for some assistance from all you people
who favour different CAD packages to run you CNC
equipment. In a previous post I mentioned that my interest
is ‘Servo motor control’ but I get the impression that most
Software used and discussed here outputs step/direction
Information for stepper controlled systems.

The control I have developed will read ‘G’ code and ASCII
Lists and I am working on a DXF file reader so I can link to
Some of the CAD packages I read about on this board. I am
Including a link http://freespace.virgin.net/mmj.potter to a
Sample program from my controller. This program generates
A helical volute toolpath. I am hoping that those of you who
have experience with different CAD packages will draw the
toolpath and email me a copy of the DXF file so that I can
compare the results generated by my converter.

I hope that is fairly clear!!
If who have any queries contact me at
mmj.potter@virgin.net

Have fun
Mike P.

Just to clear your thoughts about servo control using step and direction. It can be done by using a Gecko G320/G340 servo drive. It accepts step and direction control.

Thanks Jeff

I understand the Gecko drive system and I think it's great for converting stepper outputs to servo motor control. My controller outputs are the same as the Gecko drives and also performs the same PID servo control alogrithms .

What I don't have is a clever graphics front end.

Thanks again for your reply all information gratefully received.

Regards Mike
