Thank you!

You are actually the one who made me think about touching a machine with a dead controller

You made a really nice job of that.

Scope reading with 1000 nanoseconds:
 

And with 900 nanoseconds and increased following error:
 

On a LinuxCNC 2.9.4 installation I find 'change.ngc' in '/usr/share/linuxcnc/ncfiles/remap-subroutines', so I am pretty sure everything in "nc_files/remap-subroutines" is copied there during the installation of LinuxCNC.

So we only need to move 'change_g43.ngc' from "configs/sim/gmoccapy/macros/" to "nc_files/remap-subroutines" and maybe adjust the path in the sample config(s).

 

Hello everyone,

I completed the work on my milling machine and have made a video showcasing it. At the moment it´s only available in german but I already recorded an english audio track so as soon as I figure out how to add this you will also be able to watch this in english.



Once again big thank you to everyone here who made this possible, I couldnt have done it without you!!

   

Hi all,

I am trying to understand and implement the caxis.comp with my lathe. 

My setup is:

VFD with ac motor for "normal" spindle mode (analog signal --> pwmgen)
C-axis is connected via a reducing gear to the spindle, the c-axis motor is a closed loop stepper (step/dir). The c-axis drive is engaged to the spindle with a pneumatic cylinder. Normally it is disengaged

I am trying to better understand the caxis.comp and was wondering if someone can shed some light on this:

pin in float spindle-revs --> connected to spindle.0.revs
pin in float spindle-velocity-in --> connected to encoder velocity signal
pin out float spindle-velocity-out --> ? velocity signal for pwmgen and/or step/gen ?
pin out float position-fb-out --> is this position feedback calculated from encoder velocity signal ? is this connected to joint.xx.pos-fb?
pin in float pid-in; --> connected to PID output of c-axis
pin out signed state; --> what is this for?

Has anyone used this in similar setup (spindle with pwmgen, and c-axis with step/dir). Should the step/dir generator be run in velocity mode?
Would probably help to have some insight.

I have also tried a similiar thing using the mux component and connecteing the encoder signal to the c-axis feedback or not (depending on the mode). But as others have experienced there is an ussed with joint following after switching back to c-axis mode. Even when reseting the encoder position to 0, this will only work if the c-axis is also at 0.
I also could not achieve proper orientation (homing) when switching to c-axis mode.

Will keep trying ----

Hi, there,

i am trying to make a keyboard shortcut to toggle between TURTLE and RABBIT jog mode. I think that the code should have look something like this: 

        if keyname == "r":
            "some toggle event goes here"
            return True

It is shown on in the def on_key_event section in the code attached from line 3052. Can you help me which event should I use to toggle jog modes? 

 

That would be the PID deadband pin.
