The original thread was getting way long, with a lot of info spread out.
Pleas pay particular attention to the hal_gpio stuff, there is a basic 3 axis mill config that works. If you get any errors when thrying to use hal_gpio, unless the error log states "no permission" the issue is a permission error (which should not happen), otherwise it is related to the GPIO pins selected or somethng else. Mostly this occurs when a user attempts to use the SPI allocated pins without disabling the SPI interface.
What I suggest to the RPi users is to bookmark the Index thread forum.linuxcnc.org/38-general-linuxcnc-q...l-images-only#325007 for later reference . 

The major difference re GRBL & Linuxcnc is that Linuxcnc (what runs on the PC) is interprets the gcode and works out the timing & responds to realtime events.

With GRBL the PC sends gcode to the GRBL controller and that interprets the gcode.

There is no option (and so far it does that like it will ever be an option) to send gcode to an external controller.

UNITS = INCH # issue a G20 at load
DEFAULT_UNITS = INCH # same as G20

Remove the comments from those two lines.

Talking about having to drop this menu down and change every time. I thought i changed everything in the ini related to units (attached).
 

 

forum.linuxcnc.org/plasmac/40057-camera-for-touchoff
There was/is something for PlasmaC and/or QtPlasmaC, but i can not find it, might be in the manuals, but searching for it now i noticed some of PhillC videos have been removed from youtube.
It did skew adjustment also, when the plate was not placed parallel, etc.

Anyone have any experience with using machine vision with LinuxCNC?  Specifically I am looking into adding a camera to a CNC router for automating the touch off process for part location and size checking.  I want to be able to fixture a part (a frame) to the table then start a routine that would find the edges of the frame opening, make any needed adjustments to the part coordinates, and g-code (adjust a parameter or 2) and then mill the piece.

Does this sound like a reasonable task? Anyone already done something similar?

Did you finish your project, did you use the original encoder or did you change it?

i will try that tomorow
thanks

I don't think you will get much help without a description
of your Modbus hardware and software setup.

electricity is back here ... last slave is your EP box ... check the config but there is no SDOs setup .. I think you will have to create some over the SDO object and then translate them -> object 0x8000:01 .. 17 

but it's also legitimate if you don't want others to use it, why look for loopholes?

There is now an alternative

Maybe there is an eeprom setup and you will have to overwrite something in the eeprom .. because I can not see any SDOs in the startup list out of SM configuration... From the dmesg you are still tring write SM managers what not exist for them... 

My setup before the translator was ... Active configuration, unplug the TC3 master plug lcec master.. ethercat pdos ... And just rewrite active config then I have exporting the SDO config and everything works everytime..

You are using the TC2 instead TC3 .. there should be problem of crashing because I did the translation over TC3 withe 20other slaves CoE or SoE and it works well... Use just TC3, it is better and it is free... Did drag and drop file to the console? Because you have to insert full path ... I am in the heavy storm right now and I can not check your stuff ...

# 3. Execution of this software or parts of it exclusively takes place on hardware
produced by Synapticon GmbH.

of course you could just use it, no one will be able to prove it,
but since I'm trying to integrate EtherCat into RIO,
I can't use it so easily in my project.

Before looking further into this, There seem to be
no hal connections that set the spindle directions.

That is, there are these net statements:

net Y73-SPFWD <= spindle.0.forward
net Y74-SPREV <= spindle.0.reverse

But signals Y73-SPFWD and Y73-SPFWD are not connected
anywhere else in the hal file. Normally I would expect
these to connect to some direction control output bits.

How is direction controlled on your VFD?

@scotta, I just tested the 3.1.4 unfortunately it's still the same no change. Spindle dips to nearly zero while in CSS
