First off I have managed to get EMC2 Live loaded onto a computer and running. Lots of changes since the last time I looked at EMC, I really like the graphics in the AXIS interface, makes debugging programs a lot easier.
I did translate a program that was running on a Fanuc control and got it to run on EMC. A few things I had to change. All with AXIS, I have not tried the others. 1. I could not get the G28 position to work right. 2. Had to remove the G68 G69 rotation from the program. 3. Could not find a way to get to the tool comp numbers. So had to put tool radius in a variable, #107 4. Some funny stuff happening at the tool change, may be related to the G28. 5. The work offsets seem to be ignored. In the MDI panel the active codes displays G54 regardless of what is in the program and even changing the G54 location in the .var file is ignored. I found the reload tool table in the menu but could not find how to reload the variable table. Question is there some place in the interface to see what the current values of variables are? I find it handy to watch the numbers while the program runs to make sure the calculations are being done the way they were intended. Also nice to watch pass counters to see how much is left to go, the graphics display also gives that info just not in a quantized form of a number. Here is the program if you want to try it. **************************************************** *** **** **************************************************** (MILL CONCAVE RADIUS) (WORK ZERO) (X AXIS CENTER OF PART) (Y AXIS CENTER OF PART) (Z AXIS TOP OF PART) () G0G17G20G40G49G80G90 G91G28Z0M5 (G69)(TURN OFF ROTATION) () #100=-1.0000(X START) #101=1.0000(X STOP) #102=2.000(RADIUS TO CUT) #103=[90.0/30](ANGLE STEP SIZE) #104=0.5000(DEPTH OF RADIUS FROM Z AXIS ZERO) () #105=3565(SPINDLE RPM) #106=21.39(FEED IPM) #109=2(TOOL BALL ENDMILL) #110=59(WORKSTATION) #107=0.1875(NOTE TOOL RADIUS BECAUSE CAN NOT FIND EMC TOOL TABLE) (#108=0.0)(PART ROTATION ANGLE) () (START AND END ANGLE SHOULD BE) (BETWEEN 0 AND -180 AND THE) (START ANGLE SHOULD BE) (GREATER THEN THE END) #111=45.0(START ANGLE OF RADIUS) #112=-45.0(END ANGLE OF RADIUS) () (DO NOT EDIT AFTER THIS LINE) () N1M1(FIRST TOOL) T#109M6 M1 G0G90G#110X0.000Y0.000 (G68X0.000Y0.000R#108) S#105M3 G43Z1.000H#109(M8) () (NOTE 13000 IS THE START OF THE TOOL OFFSET TABLE ) ( FOR THE FANUC NEED TO FIND THE EQUIVALANT IN EMC ) (#150=[-#[13000+#109]+#100])(X START POSITION) (#151=[#[13000+#109]+#101])(X END POSITION) () (NOTE FIND OUT WHY THIS NEXT LINE IS BAD??)
