RE: [CAD_CAM_EDM_DRO] Re: servo2go Model-II card and anyother software than EMC

Hi Asim
It is true I run G21 and inch. I do not use offsets
other than G92.

As Pauls says...get on the developer list and the IRC channel.
Big things are coming we hope...and we need your help.

Hi Les


Thanks for your reply. I think you have been using EMC with default
startup code as G20. if you set the default startup code in the ini to
G21 then you'll be able to feel my pain very quickly.


You'll find the follwing bugs:


1. EMC does not jogs in mm. although you are running your machine in
mm by default.


2. EMC messes up with loading of work offsets. It multiplies each


workoffset with 25.4 and loads it. this way you never can use emc in
mm mode as default.




There are many other bugs like:


1. EMC sometimes picks some very slow feed value for G0 rapid move.


2. The homing polarity reverses for z and x axis. to fix this i run
emc first time with EMCMOT = stg2mod.o. i exit and run second time
with EMCMOT = newstgmod.o


3. you can not set and use workoffsets manually when you are using the
EMC in mm by default. to use workoffsets what i do is as follows:


I have defined in the run file a copy command that copies the var file


which has all the workoffsets set to zero. and i use G10 command in
each program to set the workoffsets




I've been writing about the bugs i find in EMC but each time i
download emc i found these things unchanged, and never addressed.




By the way please tell me what is EMC-II? Does it has fix to the bugs
found in EMC-I ??




best regards




@sim
