yes - this is exactly what I wanted/needed with the gui defaulted to L11 it will be sweet on most mills I don't see any reason g59.3 would be used for anything other than this thanks On Fri, Oct 8, 2010 at 4:35 PM, Chris Radek wrote: > On Fri, Oct 08, 2010 at 04:22:40PM -0500, Stuart Stevenson wrote: > > > wow - that works good - thanks > > what took so long? :) > > > Fixing the existing bug I noticed while testing the new feature... > > > Do you think this is an OK solution to your problem (once we make > the GUIs use it?)

Re: [Emc-users] setting tool lengths
It looks like there's more than one way to get Z0. For what it's worth, here is how I do it on our Haas mill. It is also how I plan on doing touch off and tool pre-setting on my EMC2 mill: First, to use this method you must measure tool length using a tool holder mounting fixture and height gage. An actual tool pre-setter would also work. Both will result in positive numbers. Next mount a coolant proof dial indicator in a tool holder. This is the type with a locking bezel pointer. Put this on your pre-setter and make your new tool measure some round number, say 7. inches. Lock your pointer at that reading. Put that tool in your ATC carousel just like you did with your edge finder. Now when you are setting up a job do these 3 steps: 1 - Jog the indicator down to the part surface so the pointer lines up with the bezel mark. 2 - Press "Part Zero Set". Your gage line is now 7. inches from your part surface. 3 - Add negative 7. to your G54 Z register. This eliminates the need for swatches of paper or wood because your new tool is already compliant yet very accurate. I hope this helps.

Don't put them so close together; inhibit breeding. ;-) Ok, so it is late and I can plead old-timers syndrome or something. I keep thinking about a gage ... basically a honed cylinder with a spring restrained piston and a couple of prox switches. The first switch is a warning and slows the approach velocity and the second marks the length. One can either bolt this to the mill bed or use magnets to affix it so positioning it on top a work piece would be possible. Gage all your tools against it using the reference tool as zero. Set it atop the workpiece and use the offset to get workpiece zero or use cradeks dowel method. It should not be too difficult to clone this across machines to make things consistent. Surface grinders do nice things. :-) In this off the wall thinking I have even considered a reverse version of the sensor system that mounts in the spindle and allows touch off plus offset to give top of workpiece. There must be a somewhat easier way but indeed it is late and I'm somewhat taxed for bright ideas. In the light of morning maybe something else will reveal itself but I don't hold out too much hope. Keep thinking, it is the only hope we have. Dave > > I want to have a variable (in the .var file?) that will allow me to set > > positive tool lengths using a tool set block on the table surface.

Re: [Emc-users] setting tool lengths
At the moment I like the idea of the .ini entry and forcing the user to do it one way for every machine. The tool set machine measurement can be typed into the TLO for the times when the tool set probe cannot be reached. I would then need to make/purchase a 40 taper tool set standard adapter for my tool set machine and all would be well. You are correct - it is late - time to sleep on it. -- dos centavos -- Beautiful is writing same markup. Internet Explorer 9 supports standards for HTML5, CSS3, SVG 1.1, ECMAScript5, and DOM L2 & L3.

I currently have G59.3 system on my mill set so the reference/zero length tool (probe length for me, gage line for you) is touching the table at Z=0. That way I can switch to G59.3, put a 123 or 246 block anywhere on the table, roll a .5 dowel pin between the tool and the block, and touch off the tool to 6.5 (if using an upright 246 block). Then I switch back to G54 or whatever. I think this procedure would do what you want too, if you just set the coordinate system right. It would be nice if you did not have to remember to switch systems though. It is easy to mess up. Maybe we need a separate system just for tool touch off, or maybe using G59.3 automatically under the covers is good enough. Either way, we'd have to make a new subcommand of G10 L10 Pn (not sure what format? L11?) that does the deed. Then (the hard part I think) is letting the user select which method in the gui (touch off tool relative to current work offset, or touch off tool relative to the specific special/G59.3 system). I'm hesitant to force one or the other - I usually use the table method, except when I can't. Sometimes I can't get to the table at all - so I probe the top of the workpiece, set G54 to 0 there, roll dowel between tool and workpiece, touch off tool (while still in G54) to 0.5. An easier way out would be to leave G10 L10 alone and change the behavior underneath to force relativity to a certain coordinate system based on an ini entry. Then we wouldn't have to touch the GUIs (but different emc machines would work obscurely and dangerously differently with no hint to the user). It's late - this is probably clear as mud.

[Emc-users] setting tool lengths
Gentlemen, I have asked this before but with the EMC2 machines breeding in my shop I want to get this implemented. I want to have a variable (in the .var file?) that will allow me to set positive tool lengths using a tool set block on the table surface. I want to be able to match the tool lengths the machine sets to the tool lengths our tool set machine measures. The variable would be a constant that is compared to the axis position to calculate the tool length from the imaginary gage point. I have a 50 taper tool set standard I can put in the spindle to determine the gage point very accurately. Our 5 axis mills that have 5 axis tool length compensation need and use positive tool lengths in the TLO. I would like to have positive tool lengths on all machines just to be consistent. I will start working on this here unless someone (with much better programming skills - wink wink) has completed it. :) thanks Stuart -- dos centavos -- Beautiful is writing same markup.
