One trick is to not have an M02 at the end of the program. This gets a warning message, but doesn't reset the offsets. I think you can reinstate the offsets with G92.3.

Re: [Emc-users] Reset of offsets after running program
We *could* have a bit to set in the INI file to kill this feature if the owner so desires. All it would take is an implementor with the proper skills who desired to do that. As long as the default was to "do the right (according to specification) thing" I certainly wouldn't object to it. I, too, am running BDI and using TkEMC. The next time I'm ready to reinstall, I'll switch to Axis, but I can understand your frustration. I'm anticipating that the switch might be painful, so I'll probably install the new system on a second machine so that I can still get work done as needed while I'm playing with the new system. It is unfortunate that I'll have to do that, but it is a common problem. I have the same issue with upgrading/changing my phone system from [EMAIL PROTECTED] to Trixbox. I'll need a spare machine for that, too.

[Emc-users] Reset of offsets after running program
Okay, I am making a request/plea. Refresher, I loaded up EMC2 after running BDI for about 3 or 4 years and I use TkEMC (because I like it!!!). After running my first program EMC2 reset my offsets to what the machine started at. So I asked the group why is it that BDI didn't do this and how come I can't use the right click on the axis to set the offset. The jist of the answer I got was "because thats not proper edict".

[Emc-users] TkEMC Continues and Increment indicator bug
I just wanted to ask if anybody had fixed the problem in TkEMC when you press the c key, the display screen display of continuous and the increment value should change/toggle and it does not. It would be really really great if someone could fix this. Andy - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
