Hi Shane,

Do you have a intermediate program that uploads the gcode in your machine ? 

I work myself with cambam which is creating the gcode for a reichenbacher machine. With the help of some people there they created my postprocessor and it works very well. I already post a question for your machine. If you have more info to give me please do so. What is your line of work on the machine ?

regards

Hi Peter and Stephane,

Thanks for this info.

Both Aspan and Pratiko seem to be possible solutions for running DXF through older CNC’s.

I’ve never personally tried them but if they can process DXF running Polyboard will be easy.

However, if I was buying a second hand CNC I wouldn’t get a machine this old. Too much hassle finding parts and support.

A few years ago I was employed to set up an old Giotto SCM machine for a company and although I managed to get all the software working with DXF etc. we still had never ending problems with relays, motors, end electronics and with no really tech support from SCM it tooks ages to find and repair. Really not worth if for a business where time is money. 

When all was added up with down time, and my fees, the company who paid me could have bought a new machine with the same money.

All the best,

Ness

Hi Ness

Back in the early 1990,s I had a Morbidelli auther 504, which i upgraded to a later model mid 1995.

These worked well with Aspan, we could also import from autocad.

Hope this helps

Cheers

Peter

I use Pratiko + CAD CAM from cnsolutions.it/ for my Biesse Rover 346 and 322 works great for dxf import.

When exporting file it makes the cni format. Then it makes a floppy image of the file then transfer via serial port or usb floppy

emulator to the machine.

Hi Vidar,

No more than has been already said.

Aspan seems the only promising lead .

You can see more info here:

Hello everyone,

I’m starting this post because I often come across the problem when people have an older CNC that can’t directly use DXF files from Polyboard or StairDesigner .

Both Polyboard and StairDesigner write very nice clean and well organised DXF files that all modern CNC can use directly either in the software installed with the machine or through  other CAM packages like Vcarve, ArtCam,  EffiCad etc.

But problems arise when the CNC machines are older and can’t read DXF. 

This is the case with Shane who has a Morbidelli author 504 mod: TRIA 7500 1996 machine .

I have another person who is having the same problem with his Biesse Rover CNC.

These machines require a special CAM package that can write the specialised code that the machine can read.

I have come across this problem several times with other machines and never really found a good solution.

This time I have a bit more hope with a software package called ASPAN.

I have contacted the editor that is Atool software in Italy and they claim that the software can import DXF and write old Biesse and Morbidelli code.

I’m waiting for more information and will keep this thread updated as it comes in.

If you have any other ideas to help Shane please post here as these older machines are cheap and very heavy duty and can be a great investment if they could just easily interface with modern DXF output.
