[Emc-users] Machine coordinates & offset madness!!
I am trying to get my printer setup with the correct home coordinates and have it read 0 for x,y & z and everytime I start lcnc it shows z having -235.211 something and I have NO IDEA where its getting this from? I zeroed out the .var. If I touch off the z axis it will make it 0 but the -235.xxx moves to the G54 coordinates. If I then zero the g54 offset it goes back to the DRO coordinates.. That number bounces back and forth without every becoming 0!! I don't have limit/home switches hooked up yet and was "hoping" to manually move the Z to the "home" position and have lcnc see it as being at 0. So if I issue a HOME ALL it will just call itself home without moving the machine. Right now if I press HOME ALL it makes the -235.xx as home position. How do I reset everything to 0 in lcnc? Where is it getting this -235.xxx number from anyway?? Bob -- Learn the latest--Visual Studio 2012, SharePoint 2013, SQL 2012, more!

The best way to understand all this is to read the HAL and Integrator Manuals on the LinuxCNC wiki pages. I had the same question(s) and this pretty much cleared it up. If you are able to read through the source code you can see exactly what's going on. http://wiki.linuxcnc.org/cgi-bin/wiki.pl?LinuxCNCKnowledgeBase Bob -- Learn the latest--Visual Studio 2012, SharePoint 2013, SQL 2012, more!

If are familiar with electronics you could get the prototype cape and wire up some I/O line drivers to them and connect right to your stepper drivers and with Charles' MachineKit image be good to go. The BeBoPr just does the same thing but adds the MOSFET's to control a 3D printer's heated bed etc... Also, the abitlity to connect a touch-screen is there as well. I believe the drivers in linux are availble to read the input from it as well. It would be nice though if there was such a Parallel Port Breakout type board pre-made for those that need that option and provided the connectors ready to be wired up..

Currently it seems that Andy is right - you see relative (workpiece) coordinates so simply do "touch off" for Z axis. Ideally for testing purposes you might want to set workpiece and machine coordinates to be the same. You can switch Axis GUI to show either machine or relative coordinates with Shift+3 combination to see, what is the difference between them. In MDI you can also command a movement in machine coordinate system by adding G53 before G0 word. This is one more thing you can use for testing. It looks to me that there are few things for you to learn about all these various coordinate system things, so here is a link for a start: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?CoordinateSystems " A fter reading t he above link you offered that answered alot of questions in one short page!! I am not sure which coordinates they are to be honest, but since that page said the default coordinates are G54 on startup then I would think that they are relative. I understand how the coordinate systems are working in LCNC now and alot less confused :) I am going touch off the Z axis to 0 to bring it under the machine limit of 200/-200 in the INI file and see if I can move all 3 joints up and down like it's supposed to move. If this works out then I know the kinematics are working as planned and then I can set up the actual machine coordinates and limits to my actual machine boundaries and go from there. Its been so long since I've last used a CNC machine (home built back in 2005/6 using Mach3) and really did everything in machine coordinates on that since I was only cutting wood objects 1 at a time. I can see how powerful LCNC is now and the possibilities are endless with its G/M Codes. Thank you very much for the help!

Re: [Emc-users] lineardeltakins and 'World mode' problems
Ok, I got it into World mode and my next issue is I tried to issue the command: G0 Z10 and G0 Z-10 and it gives me an error saying the command would put the axis past its postive limit. It said this 3 times for each axis After homeing the machine and switching to World mode it made X and Y 0.0 but changed Z to -278.00 ? Not sure where it got that value from for Z? I was able to do G0 X10 Y10 before the command above and it seemed to move the 3 axis properly to that position. Its just the Z command isn't moving anything? Here is my ini file in case it helps?

I then hommed all axis and 0, 1 & 2 all went to 0 on the MDI with a * next to them all. It still said the same error message when I tried again. It seems like it wants axis(joint) 3 to be hommed also since that one still shows -0.00 with no * next to it. That is the extruder and there is no home for this axis. How can I get around this? I have the search_vel and latch_vel lines for all 3 axis's #out (commented) so technically no home or limits on machine. Axis 3 doesn't have this either. I also tried the "lsmod | grep kins" line at prompt and it just returns back to the command prompt without doing anything or showing anything ?? Did I type it wrong? It won't let me do any MDI commands either while not hommed.. Ideas?? Bob -- Learn the latest--Visual Studio 2012, SharePoint 2013, SQL 2012, more!

Re: [Emc-users] Emc-users Digest, Vol 89, Issue 6
"Are you switching to "World" mode?" I didn't even know this existed... I've read through the documentation a few times I must have missed this part... This would be AWESOME if it fixes this.. I know that when Axis did load up the Axis's were numbered 0,1,2,4 instead of X,Y,Z,A . I will give this a try. I needed to walk away for the night and take the wife out and get a fresh look at it.. Thanks Andy for the help..
