Gscreen - a GTK / Glade / Python based screen

I will definitly half to second that idea Andy, our guys have forgot to select Tool table in that drop down box and then they get all confused when they go to the tool table and their values aren't there. Then I hear them yell from across the shop at me because they can't figure out what's going on.

offset origin does work like AXIS except you can't select the user system it uses the current one.
zero origin is just a convenience button to set the offset to zero.
What it doesn't do is allow touchoff to tooltable, but yes I could add a button for that.

Using G92 seems odd, but whatever they are used to.
It seems that they are using G93 to add global offsets But I'm sure you can do that without using G92

I will let someone very familiar with such things to chime in though...

I will remind you to please please do lots of testing with Gscreen it is under development so is not as stable or tested as something that has been released for a few years.

So after reading:
www.linuxcnc.org/docs/2.5/html/lathe/lathe-user.html

The concepts are:
tool offset - The difference between the tool lengths compared to a common point - Gscreen doesn't have a button this yet, but you could edit the tooltable directly.
origin offset - The way to move that common point - Gscreen has offset origin button for this.

I can add a tool offset button which I think use the Gcode G10 L10 or is it L11 I don't quite understand why you would use one over the other.

LAIRE82 I think your guys are using G92 to avoid the offset origin idea but G92 really accomplishes the same thing.

Rick's boss here....We only G92 one tool in the turret set-up. It probably is cheating but we usually have a main tool that will be always be in that pocket on every machine we have like an 80 deg turning tool. We never really mess with using a G92 on the X axis except when loading the tool turret for the very first time so the maain tool will never have a value in the fixed or geometry offset we use the assignable or wear offsets to make fine adjustments this is why the FANUC Style patch is so important to us . We do however use G92 in the Z axis everytime we change a job or a lenght of material. Once all of the tools are set-up to with offsets we can use any tool to touch off the face of the part and G92 the new Z 0 position. We always program the face of the part Z 0.

Our use of G92 probably goes way back to a GE controller that nobody could figure out how to move the axis origin on....G92 just always worked and our guys could wrap their heads around it very easily. Your axis origin button is fine and in time we will teach our guys how to use it. I just want to say that the Gscreen is a very nice interface and much more touch screen friendly. My machinists keep putting a mouse on the machine with the Axis display and it drives me nuts just for the fact that the mouse will not last out there and we will end up with a mouse shortage....LOL
