G153 maybe not working right in Imperial mode

math_indy

I have parameter #115 set to 1 (imperial mode) and it seems that G153 behaves very strange.  


I have machine coordinant (X0.0) HOME signal at the X- limit so all machine coordinates should be positive but when I execute:


G153 X2.0 F6350.    (GOTO MACHINE COORDINATE X2.0 INCH AT 6350 MM/MIN)


The table moves from X1.0(MACH) to X0.9829 (in the negative direction?!?) where it hits the software travel limit but G153 X2.0 should have invoked positive direction motion?

I have not tried G153 in mm mode.

My programs that use G54 coordiants and G01 motion all seem to work well.

Much better now

1. Add G20/G21 recognition macro variable (#448): in G20 mode, #448=25.4; in G21 mode, #448=1, used to correct the bug that G28 and G153 instructions execute errors in G20 mode;

The implementation code for G28 and G153 is defined in slib.nc. If you are interested, take a look at how #448 works.
