General Mach Discussion / Regen Command on Lathe

« on: February 09, 2010, 01:21:14 PM »

What does the Regen commmand on the Manual Screen of Lathe do? Can anybody point to where it is documented? Nothing in the index that I can find. I clicked on it and after that my Axis DRO went a bit haywire. When I told it to jog .10 it showed a jog of from .155 to .165. I don't know if there was a connection, it is the only thing I can think of to explain why jogging suddenly became erratic.

Can you enable block skip in Mach3 Lathe? If so how and can somebody point to where in the documentation this is explained?

Yes, was using Mach3 Lathe post. Discussed with BobCAD and they say it is an error in their code. Since I don't need these commands I deleted them from my post processor.

Hi,

I am new not only to Mach3, but to machining. I have a lot of experience with woodworking and a fair amount of programming experience. I got into machining because I started making jig for precisions wood working and quickly realized that cutting aluminum on  a table saw and driling and tapping on a drill press was never going to be accurate enough for me. So I dug into options on the internet and discovered the world of hobby machining and then, glory of glories, CNC machining. I haven't been so excited since (I date myself) I first bought an Apple II computer in 1982. I have jumped in full bore: bought a Sherline lathe and Taig mill and run them with a Soigeneris controller. I am an inveterate designer and have been using Rhino CAM for several years now. I recently bought BobCAD for its CAM features and having mastered the basics of it and Mach3 am starting to cut stuff. There is a lot to learn, but that is half the fun. I recently went to Cabin Fever and got a great opportunity to see the works of some great craftsmen and and talk with them. I stopped by the Mach3 table and talked with Brian Barker a bit and was fascinated by the little Taiwan-made gantry router table he had for demo purposes. I look forward to chatting with the other forum members and hope I don't embarrass myself too much. FA.

G-Code, CAD, and CAM discussions / BobCAM G-code 96 or 97 Error in Mach3

« on: January 31, 2010, 11:20:13 PM »

Hi,  I am new to Mach3 and to CNC machining, but love doing this stuff. I have a Sherline lathe with a Soigeneris controller. I draw in Rhino, and use BobCAD's CAM to set up my g-code.  I have Smid's CNC Programming book on order and hope to be writing my own g-code soon. (By the way if you can recommend a good g-code tutorial that has demo programs please let me know). That out of the way, my question is:

BobCAD created a g-code program for me using canned cycles that is supposed to turn a piece of aluminum (or delrin) to size, cut two grooves in it and then cut it off. The program looks fine in BobCADs simulator. When I import the g-code into Mach3 I get a message saying "G96 error no S code". When I go back and make sure the CSS option is turned off I get "G97 error no S code". Since I have a Sherline mill with no spindle controls I don't want a G96 or G97 to show up, but if it does why is there no S code? I am not clear is this is a BobCAD issue, an issue with the post-processor or an issue with Mach3. Can you advise? I am also asking BobCAD about this. Thanks, FA.
