Title: Tangential Control A-axis...
Post by: Vaklin on August 02, 2009, 06:43:29 PM

Hi!
Is possible to add some M code with which will be possible to turn on and off tangential control for A-axis?

You need to make a macro for whatever M code you want to use and have it toggle oem code 241.

Found the programming manual. Will do as you recommended. Thank you!

Again about the rotary A axis... As I see the Mach didn't calculate shortest patch and every time uses positive direction. This is in absolute mode, because I don't use incremental and never tried. Also better will be if A axis knows negative digits. Something like this... Zero position (and machine zero) is Y axes on the circle. Possible values +180 to -180. Operators decision go trough 180 or not by check box. In one case calculates shortest patch via 180 in another, change direction regarding machine possibilities.



----- EDIT----
Exactly, Mach 3 behavior suits me. Positive value rotate CW, negative CCW. Will do in post-processor all rest.

Now, after week of investigation...

Please, let -0(minus zero) and +0(plus zero) in rotary axes be treated as every another digit. Now + and - relative to zero is always +.
