I guess I didn't realize the offsets were not saved which might explain some bad parts I have made. When using the option to write changes to the current work offset I never open the work offset screen any more.
Every industrial CNC I have run has saved the offsets automatically.
I think this should be the default option and shutting it off be the special option.

Hi Tom,
Just seems a little odd for them to disappear unless you save. When you enter offsets into industrial controllers they stay there until you change them. For example if you set up a job at the end of the day and power down machine, when you start up the next day those exact same numbers from the day before will be there until you change them again.
I cant really think why you want them to go back to zero? If your still running the same job you will want to be using the same offsets, and when that job is finished you will have to enter another set of numbers anyway. Anybody else have any thoughts? Thanks.
Mark

Me, too. It happened me many times that all the work I had done for determining the offsets exactly, got lost next time I turned on the machine and I either ruined parts or had to redo the zeroing job. Unpleasant. I know that I should "save" but it's counter-intuitive and I often forget it. My vote is that it should remember any change to the offsets (including those done via the "zero" and "set" buttons and direct editing of the table), by default. By the way if I'm not err the "Tool Height" function automatically saves the values (and the edits to the tools table are remembered as well). This is confusing (at least for me), I have to remember that changes to the tools table get remembered automatically while the edits to the offsets need a explicit save, and I often mistake.

Hi Mark,
Well I wonder if someone could expect when they power up the machine
that the offsets are in a known state either zero or what they have
saved previously. Not dependent on what was done last before
shutdown.
How about a "Save on Exit" checkbox on the Offset Edit Dialog that
persists.

The first thing our customer requested was that offsets were always remembered, so we had to modify that.
So maybe it should be a 3-state option: - always zero at start-up; - always set to whatever was explicitly saved; - set to last state (i.e. treat the offsets like "non volatile memory"). I guess for consistency, the same 3 options should be independently settable for tool length offsets and maybe g-code variables (other than the variables which actually save the offsets!)

The process of shutting down the machine should have no bearing on work offsets unless the user is not homing the machine before each use.
I have read that some people are doing shut down procedures and expecting the machine to start up in the same position. But that is just asking for trouble.
Honestly I am surprised this has not come up sooner. I feel like this is one of those features that just has happened for normal use. Just as the tool table always saves so should the work offsets. If there needs to be an option to change it between
saving and not saving then make it a feature switch like writing directly to the work offsets is. A checkbox, on the trajectory planner page or maybe a whole new tab for all the options. This would be somewhat like the parameters on industrial controls.
Or maybe a lot of these options people are asking for get incorporated into a configuration text file so you don't have as much work on the GUI to do.
Something like this
Display_machine_encoders=0
Auto_Save_WCS=1
Write_to_current_WCS=1
Thats just my $0.02

Hi Tom,
Yes a save on exit checkbox should work fine. Seems like most people here agree that this should probably be the default option, but I would be happy either way as long as i can change it. Thanks.
Dan, I have to admit I am using a shutdown procedure on my machine until my home switches arrive and i get time to install them. This is working well enough for my toolchanger to work and use soft limits but i agree its not the best way. My machine has cold start marks on each axis and I visually check to make sure they are lined up on start up. Working ok as a temporary soloution anyway, at least im able to use machine.

The only problem with only have a save on close prompt is what happens when you loose power or the computer/Kmotion crashes? Now you lost your offsets.
I actually was not homing for about the first month, that was until my mill tried to put the spindle through my vise at rapid speed because machine zero was down there, oops. I realized the reason for the home routine that night.

Yeah, it happened me too, more than once. Power loss while working, then power on again, then machine ruining parts until I realize the offsets were different before power loss. I personally think that the "automatic & immediate saving of the fixture offsets" should not only be the default, but it should also be impossible or very hard to change that default.

The latest Test Release now has a "Save Always" option on the
Fixture Edit Screen that is enabled by default. The option checks
for any Offset Changes every 1 second and if there are any changes
writes them to the Vars Disk File.
