Hi
I want change default coordinate system at startup - for example by edit value of "5220" number parameter in .var parameter file. I write these python codes in GUI :
varfile = open(os.getcwd() + '/' + ini_file.get('RS274NGC','PARAMETER_FILE') + '.bak', 'r')
		vardata = varfile.read()
		varfile.close()
		varfile = open(os.getcwd() + '/' + ini_file.get('RS274NGC','PARAMETER_FILE') + '.bak', 'w')
		vardata = vardata.replace('5220	1.0', '5220	9.0')
		#print vardata
		varfile.write(vardata)
		varfile.close()
		varfile = open(os.getcwd() + '/' + ini_file.get('RS274NGC','PARAMETER_FILE'), 'w')
		vardata = vardata.replace('5220	  1.0', '5220	9.0')
		#print vardata
		varfile.write(vardata)
		varfile.close()
parameter files (.var and .var.bak) temporarily changes but actually value of "5220" variable remained equal 1.0.
Anyone has an idea?

The proper way to setup the environment is with a proper preamble in each and every G code file... otherwise you might get a surprise one day. Of course you can put a start up G code in the ini file in the [RS274NGC] Section.
