Hi group

I am runing EMC with default startup code as G21
I have seen that if you use emc with default startup code as G21
and exit the program then it cant store and recall the work offsets
correctly.
for examle if workoffsets were x=-1 y=-1 z=-1 (all in mm)
when you exit and reopen emc then work ofssets are set to
x=-25.4 y=-25.4 z=-25.4

And sometimes i have noticed when you run program using G54 then
all the three axes start to travel towards an unknow position to
touch there hard limits. i think this may be due to the problem with
workoffsets storage problem.

There is another troubles if EMC is used in metric (mm) units (that
is if your default startup code is G21 or you enter G21 from MDI)
the SetCordinates dialog box found in scripts menu doesnt works.


i would suggest people to please set the default startup code to
G21 in ini and experiment with EMC to check these bugs of the
software.

No doubt EMC has lot of good features that are unmacthable to many
commercially available programs. In my country most people use metric
system (mm). If these problems are fixed then i think it will build
lot of confidence in people using them

Asim
