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

How bizzarre..i did copy the XML file from my old version of Mach 3 (2.63) . This may be the cause as the motor tuning etc was all wrong and it didnt copy across properly

Yeh a little bizzare to assign a hotkey as default that you are going to use a lot elswhere.
Still a great program otherwise

Hi All
I found out the problem and that was the M key on the keyboard was set to MDI select. Hope this helps anyone else who runs into this :)

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
