Bobcad & Radial Code

[BobNutz]

New here, great forum!

Also new to CNC. Recently came to a shop where Bobcad 17 is used to control an older Anaheim Control driver. Prior to my trying my hand at using Bobcad to code the cuts on an XYZ router, the other guy had made many cnc files to cut with. All his files are nothing but X,Y,Z coord to cut the entire project. When I tried this using a different machine using BC 17 I get I & J codes for radial. The router is hooked up through the AH driver and to a PC using very old G-code software to run it and it doesn't understand I or J codes. As I read through the older code it appears non modal and every arc or circle is made with nothing more than x,y,z coords. I've tried everything to replicate this same code but can't get 17 or any newer version to output code in strictly X,Y,Z without going I or J on me.

Any ideas on how to get circles and other radius objects to code in strict x,y,z output without radius codes?

Thanks

You could divide the circles and arcs into many parts. Change: Break: Divide
To stop the controller from reading past the I, replace all the I's with (I . Edit: Replace.
This is if '(' is the symbol for end of block. I have a Fagor and use ';' and not conversant with Anaheim Control. Someone else may put us right.

You can also interpolate the Arcs.

Go to 3D
Click on More
Then Interpolate
Try selecting Region and modify the Accuracy(the smaller the value the more lines, but also the smoother the arc.)
Click OK
Drag a box around the part(s).

Everything will be converted to line segments.

well after much thought, we just updated to the new Bobcad, downloaded the TurboCNC post and put in TurboCNC. I have to say that I like Turbo better than the old G-code for Win95. Seems to be more responsive and I get escape key kill switch ability whilst seeing the z depths as they change.

Overall, I guess it was time to update.

Thanks guys.
