General Mach Discussion / a axis as a linear axis
« on: May 20, 2010, 04:35:14 AM »
Hi All
I am trying to do some engraving on a circumference for a machine dial. I set my A axis as a linear axis in general set up and calibrated it so 144 mm linear movement gives 1 rotation on my rotary table (800 steps per mm x 72 assuming a 2mm ptch leadscrew). The G0 commands work perfectly but as soon as I do an MDI G1 command it seems to revert to angular motion and feed rates. I thought I might be able to do this without axis swapping as my Y motor is hard wired to the stepper driver and it seemed an elegant solution. I have also tried slaving the A axis to the Y axis and disabling the Y axis but the rotary table motor just jitters and screams...not good. any suggestions . I know I should work in degrees for rotary axes but going through my code and converting all Y moves to A angular moves seems really tedious. I have tried CNC wrapper but  on conversion the feed rates in A axis are way to slow so you have to move the  A axis move to a seperate line and and add a seperate feed rate...clunky at best!

any help appreciated


General Mach Discussion / No mCodes in MDI mode?
« on: April 17, 2010, 10:59:50 AM »
Hi All
Ive been using mach 2.63 for a while and updated to latest version last night. For some reason I cant seem to type in M3 and M5 in MDI mode as i used to. The spindle is working and I can start it using the F5 key. is this a new safety feature or am I missing something in the setup?

thanks in advance


LazyCam (Beta) / DXF loads incorrectly from turbocad
« on: March 20, 2006, 05:42:38 AM »
Futher to my inability to load DXF files to lazycam I can now do this (my own stupid fault that one   :-[). However Tthey do appear corrupted as per attachment.
The first attachment is how it looks in lazy cam and the second is how it opens in sheetcam (correctly)
Any ideas  ?????
