[Emc-users] Touch probe functionality
I saw this question asked, but I never saw an answer. From what I have seen it looks like the ABILITY is there, but my understanding of HOW TO is a little weak. In my vision of a perfect world (yes, dreaming, again), it would be nice to issue a command, or run a routing where I could give it, starting xyz and ending XYZ (for a 3 dimension rectangular solid) and a 'spacing' unit (.01 or .1 or 1, or whatever depending on the units and a probe would start at one corner and probe to the other scanning the rectangular area. It might need a probe tool diameter and a 'safe space' (how far above the upper Z to go to ensure clearance when going to the next point. What I would like for output is something that is a point cloud, either as just points (x,y,z) or in another format that might be used in the image-to-gcode program that is with EMC2. ref: http://www.linuxcnc.org/docs/2.1/html/gui/image-to-gcode/index.html This would allow 'copying parts' and the such. Yes, I expect it could/would be slow, but getting the job done is more important than time. Could someone point me down the right path? I would love to add the docs of 'how to' to the EMC wiki if I can get it to work! ...

Re: [Emc-users] Touch probe functionality
I did this in EMC 1. At that time I had to write a special program to do this. The program talked to emc through NML and wrote out the g-code file. However I believe this can now be done in EMC2 with just a g-code sequence. Be advised that it takes a long time to probe even a small area in this fashion. I did a 4x5x1/2 region at .01 inch resolution and it took something like 4-5 hours. Because of this time issue I moved on to looking for other digitization solutions. - Original Message - From: Jack Coats [EMAIL PROTECTED] To: Enhanced Machine Controller (EMC) emc-users@lists.sourceforge.net Sent: Sunday, November 16, 2008 7:04 PM Subject: [Emc-users] Touch probe functionality I saw this question asked, but I never saw an answer.

Re: [Emc-users] Touch probe functionality
I hate answering my own messages, but I found what I wanted. I promise, I tried to look first before I posted, but life happens. There are samples in /usr/share/emc/ of .ngc files that deal with probes and logging data. like: gridprobe.ngc probe-hole.ngc smartprobe.ngc tool-length-probe.ngc ...

[Emc-users] Touch probe functionality
Hi all, Thinking of making a touchprobe, but Im missing the link between the probe itself and EMC controll. Is there a special piece of code that needs to be run to locate a corner (tell EMC to do the moves), or it this already know to EMC.. What about logging a point cloud.. is this something EMC can do..

hi Kim i've just done something like that for qualifying my converted mill: http://homepage.bluewin.ch/andyfrommel/6101.html (sorry, it's still in german... but lots of pics) i selected the pin on the parport, where the prober was connected to, as the probe input and used the G38.2 command for probing. to get the coords you can make use of ' probeopen' i used this code snippet to qualify the probe itself by measuring the z-coord at the same xy pos 50 times.

Be aware that in CVS trunk there are new probing modes that let you do more advanced things. These will be in the not-yet released 2.3 versions, but if you want to build and run trunk you can. http://www.linuxcnc.org/docs/devel/html/gcode_main.html#G38.x%20Straight%20Probe - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100url=/ ___ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
