Re: [Emc-users] Adjusting Work Coordinates and Offsets?
I think these have been suggested, but just to clarify (as much in my mind as anyone else's): (a) Assuming you decide the Z height is to be 0.1 lower than it is at the moment, use MDI mode to go to a known position (say X0 Y10 Z20), Step Jog down 0.1 and Home Z to a value of 20. (b) G92 can be used, with care, and that can be set manually, so once you know how much you need to add (+ or -) you can manually enter the appropriate G92 using MDI mode. Go to X0 Y10 Z20 then, assuming you want an extra 0.1 on Z, G92 X0 Y10 Z19.9 should apply a global offset. G92.1 will cancel that offset. (c) You could alter the tool offset in the Tool Offset table. I think this can be done quickly and conveniently via FileEdit tool table, or if you issue a T~ M6 command, but it would let you enter a new value directly. Once completed, you need to invoke a G43 to have the change take effect, but that could be in the program when it runs, anyway. (d) You could use a G10 L20 command. Take the tool to a known position like X0 Y10 Z20. Assuming you want to make it X0 Y10 Z19.9 (so that you are effectively getting an extra 0.1 depth next time you run the program) then type G10 L20 X0 Y10 Z19.9 and LinuxCNC will calculate the offsets required to assign those co-ordinates to that point. That is done in MDI mode. When you run the program again, the Z will be 0.1 lower without altering the depths in the program. (e) Less handy - you might be able to leave the G54 offsets as they are, but always add a variable whose value is picked up from a memory location. The added-on value would be set manually, either by defining its value at the start of the program (so this would mean a quick edit to set its value), by placing it directly into the memory location using MDI mode, or by defining a button to set its value. When the program runs next time, it will pick the value up and add it on to the position. This is a bit like adding a wear offset (see http://comments.gmane.org/gmane.linux.distributions.emc.devel/6631 ) which is not currently implemented in LinuxCNC. I have not tried this. These would all require some testing and checking, as my machine is off at the moment, so I have not tried these out (although the situation is familiar enough, and I have used (a) to (d) regularly. Simplest is best, of course, so (a) is often enough for my jobs.

[Emc-users] Adjusting Work Coordinates and Offsets?
Is there a simple way to add or subtract a small amount to the offset for an axis. It seems all the G10 commands replace the stored value, What I would like is a comand that adds to the old one regaurdless of machine position . Is there such a thing? How hard would it be to make one? I need this for a wood carving machine. The machine operators often need to make small adjustments to the depth of the carving, bumping it up or down a few thousanths. Using touch off is a bit cumbersum, the operator either has to do the math to figure out what the new offset should be and type it in, or jog the machine from the machine 0 (where the machine parks) to the new part 0 then touch off. I would love to be able to set up a pyvcp panel with buttons like incremental jog buttons that could jog the selected coordinate offsets incrementally. But I don't see an easy way to set this up. -- Todd Zuercher mailto:zuerc...@embarqmail.com -- Master Visual Studio, SharePoint, SQL, ASP.NET, C# 2012, HTML5, CSS, MVC, Windows 8 Apps, JavaScript and much more.

Re: [Emc-users] Adjusting Work Coordinates and Offsets?
This takes some special work for your g code, but I have done something remotely similar. What I did was use the G54-59 offset system and G file subroutines called from pyvcp. If I have this straight in my mind what you are doing, it would be something like this. 1. Home to G54 x,y, and z. 2. Pre-define some variable(for Z offset) that is set using a g subroutine called from a pyvcp button/value combo. 3. Include a subroutine or code in your G code(set up your post processor to include it) that sets up G55 based on G54 + your Z offset, and sets the coordinate system to G55. 4. Include code ending to put back to coordinate G54. One downside to this, is that unless your chosen variable is persistent, it won't show up correctly in the axis preview. One workaround is to use one of the unused persistent variables from something, or the way I did it, I custom built linuxcnc to add some loose persistent variables.
