[Emc-users] converting TO a Mesa 5I25
Hi all; Received my 2x Mesa 5I25 plus 1 7i76 (the stepper interface) One of the 5I25s is going into a sw-stepper to Gecko G540 based box, on a mill with rotary table, touch probe and mpg. Other than starting from scratch with pncconf, is there an easy way to convert the ini files by hand to the 5I25? I do have this mill set up the way I want it to be. The ini files are hand-modified. In case you are wondering: Why go 5I25 for this mill? a) computers for mill and future cnc lathe are then identical, hw/sw wise; b) work through the 5I25 so that I know how it works under the hood before tackling the CNC lathe. I do have pncconf up and mainly running (thanks Chris Morley) but wonder if it might just be really easy to do the conversion by hand. Thanks for any advice you can give this newbie; John A.

Re: [Emc-users] converting TO a Mesa 5I25
Basically you just need to change the pin names to match the 7i76 and change to the 5i25.

For both methods one needs to have a good understanding of HAL. Going through the HAL tutorial might be a good place to start. http://www.linuxcnc.org/docs/html/hal/basic_hal.html Once you get comfortable with using a terminal to load modules, set up threads, run functions and connect pins to nets. You can look into using Glade and GladeVCP's HAL interface to put a face to your HAL back end. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA -- Master Visual Studio, SharePoint, SQL, ASP.NET, C# 2012, HTML5, CSS, MVC, Windows 8 Apps, JavaScript and much more.

The mill 5i25 is going to be driving a Gecko G540, so maybe the changes are not that great. I have read before about adding to the servo thread, even for stepper -based machines. I do however seem to remember some issue with step pulse length generation; that should be simple enough to find in the mailing list again. Thanks; wish me luck! John A.

[Emc-users] Homing?
Greetings all; I just trim to trim the z backlash (its hopeless, wait for new ball screw) and set my auto-zero-cal code up to establish its home position as being the back end of this gage I have made. The code I think, is doing exactly what I wrote it to do, but when I run it, expecting it to set the co-ordinates of g54 properly, I find its setting it relative to whatever it thinks home is. Not at all useful. It appears that I need a method to use this gage twice, once to home the lathe, and then to establish the offset, the touch off IOW, doing both again when I have completed a part and have brought the stock thru the chuck and re-clamped it in preparation for making the next copy of the part. So it appears I will need to do an ini axis homing section, per axis to home it, but this is going to need a switchable home method dependent on the tool mounted since the x home will need to be searched from the outside in for a normal tool, but from the inside out for a boring bar tool. So, is there a way to use the tool number to switch this homing sequence? Or, alternatively, and AFAIAC, the much better way, a method of setting the home position of an axis from gcode? Something like a brute force setting of one of the $5xxx variables? Home as one of those vars, doesn't seem to be assigned in the rather limited list included in the G54-etc section of the gcode. All that covers is the variations of co-ordinate systems. Then, can I 'net' the debounced signal from the probe, into the motion.home tree somehow, but without normal probe activity mucking with motions idea of 'home'? Thanks for any guidance.

[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.

[Emc-users] Servo Tuning
We finally have the test system up and running. We are running servo drives. The drives themselves have some adjustments so the best operation will have to be a combination of drives and PID values. I can't seem to find a Hal pin that I can trace on the Halscope to measure either required value/Actual value or the error between them. I presume that would be the best way to tune the system.

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.
