Steps to make a bootable USB to install LinuxCNC. was created by jeffmaxwell

Steps to make a bootable USB to install LinuxCNC.

Category: General LinuxCNC Questions

I am trying to  install the Trixie/Debian/linux cnc  image that RodW recommends. Can't seem to find the right steps. I have the mesa cards, 
HP core I5 computer with 16 gigs of ram and 1 tb hard drive.  I have been using computers for a long time but I can't seem to make any progress
doing this install. Suggestions?  Any help will be much appreciated. I have had the Plug and Go kit for a few years and would like to get it working for the control of an engraving machine I am building.  Thanks Jeff

How to enter tool lenght

Category: General LinuxCNC Questions

Hi if someone could explain or give a link how to measure tool length using a ER20 and tool setter for first time to enter the length in the tool library , tool setter working using Flexgui with M6 remap working if there is a gcode example someone could show me ?

Thanks Fred

Hi Cmorley

For a while now, the 50/100 "max velocity override" buttons and the slider haven't been working. It turned out the connections (signals/slots) had disappeared. I fixed the problem and also tweaked some minor things. The red LEDs in the two axis buttons were red instead of pink, like the other buttons. I removed the blank pages on the 4th and 5th axis buttons.

Launching gladevcp panel with gmoccapy

Category: Gmoccapy

After much frustration, I finally have the gladevcp working with GMOCCAPY. All of the features I wanted to implement are working almost as expected.

At this point I find that when I activate the laser pointer from the gladevcp panel, then jogging is blocked regardless of which tab is currently active. It appears that when the toggle is active, it blocks all other functionality of LCNC. Once the toggle is deactivated, all features return to normal. Does anyone have insight regarding this issue?

Also, I googled how to close a floating vcp panel during shutdown and implementing a python handler for the GtkWidget "destroy" signal did not appear to work. Does anyone have an python example for implementation of the "destroy" signal in a gladevcp panel or have an example of how to close a vcp panel on shutdown?

Tommy: I finally found one as "sim.axis.wrapped-rotary". If you, or others, know of more I'd like to hear of them. But you're not missing anything I see, it's more my search skills that are missing.

Aciera's comment regarding adding a "!" to [DISPLAY] GEOMETRY line implements a rotary axis over a tilting spindle motion. That seems to be the missing link to get "axis" working for my implementation.

Thank you.

YES. I finally found a simulation model, sim.axis.wrapped-rotary, using XYZA. I added the line GEOMETRY = !AXYZ to [DISPLAY] and the axis display acts as it should for a rotary table on A. The "!" did the trick.

I loaded the vismach axis sim model. The axis display has the same problem as above, I'll try the "!" fix which I expect will also work here. The vismach display does function as I expected, moving part with table(s).

These should work for me. Thank you very much for the help. I will have to change units to inches and the envelope size of the machine before my code(s) will run. Also figure out how these simulations implement tool offsets. But thanks to you I see a light at the end of the tunnel.

THANK YOU!

Was heisst sind nicht 'ansprechbar'? Die Pins scheinen angezeigt zu werden.

Kommt der Fehler gleich nach dem öffnen von 'Halshow', wenn du etwas anklickst oder wenn du einen HAL-Befehl auführst?

Servus,

Antwort: Eingerichtet habe ich das über die ISO ;-) von der LinuxCNC.org-Seite, also Debian 13 inkl. LinuxCNC.

Ich habe die LinuxCNC-Konfiguration „demo2023“ vom Debian-12-Rechner kopiert und 1:1 auf den Debian-13-Rechner übertragen.

> Dein Debian 12 lief auf
> enp1s0: 90:1b:0e:c4:87:3a
> enp2s0: 08:be:ac:22:81:a7

Richtig, Debian 12 hatte zwei Netzwerkkarten: eine für Internet und eine für die Mesa-Karte.
Der neue Debian-13-Rechner hat drei Netzwerkkarten, da jetzt noch die EtherCAT-Sachen dazugekommen sind.

> Jetzt auf enp3s0 und enp4s0 (zugehörige MAC-Adressen??)

Das muss ich noch nachschauen. Ich denke, ich schaffe das heute gegen ca. 18 Uhr.

> Auf alle Fälle fliegt Deine Mesa-Karte raus.

Ok, was bedeutet das genau?
LinuxCNC findet die Mesa-Karte grundsätzlich, verliert diese aber im laufenden Betrieb?

> Gehe noch mal die Installationsschritte von Mesa durch und prüfe die Zuordnungen der MAC-Adressen.

Das war damals über das mitgelieferte Tool, wenn ich mich richtig erinnere. Oder musste ich das damals separat herunterladen? Das muss ich noch einmal nachschauen.

Ganz dunkel kommt mir da noch etwas in Erinnerung, dass bei der Einrichtung der Mesa-Karte etwas wegen der Zuordnung bzw. Netzwerkkonfiguration gemacht werden musste.

[EDIT]Das ist schon etwas peinlich für mich. Die Einrichtung der Netzwerkkarte habe ich sogar schriftlich festgehalten.

For a preview with A axis work side rotation have a look at the '!' feature that can be used in the [DISPLAY] GEOMETRY setting in the ini file:

  
GEOMETRY = !AXYZ


Note that the above option cannot handle offsets.
See this thread for more:
forum.linuxcnc.org/10-advanced-configura...axis-display?start=0



If you want a vismach model to run the code and  have the tool path rotating  with the part have a look at:
configs/sim/axis/vismach/5axis/table-dual-rotary

This is an XYZAB kinematic with A being a work side rotation (for your purpose you can simply ignore the B axis and the 'TCP' mode):

I think you should use this
linuxcnc.org/docs/html/gui/mdro.html#_ini_file_options

Otherwise LinuxCNC needs to command your motion which you are not doing. 

I'd love to see a config where you simply enter a bend list and it does the maths to determine the commanded position

Measurement Only Axes

Category: Basic Configuration

Hi All,

I am trying to add a measurement only axis to my press brake. The machine is hydraulic (a Promecam) and the bottom bed moves up when the pedal is pushed. I have put a linear scale on the bottom bed so I can measure how much it travels up. I want to measure how far it travels exactly, so I can relate this to the bent angle of the metal.

Anyway, I have added a W axis to the INI and introduced a new joint (joint 1) for it. I can see this in the Axis GUI and it all works nicely, when the encoder moves, the W axis value updates. But when I type "g92 w0" to set a zero point, it doesn't set it to zero. I think this is because the dummy joint I have added for it isn't getting its command position updated. Please see config snippet below:

HAL file excerpt
#
# Setup bed axis (W)
# (this is a DRO only, and just measures the bending depth we actually reach)

# position and velocity feedback
net w-pos-fb <= hm2_7c81.0.encoder.01.position
net w-pos-fb => joint.1.motor-pos-fb

# linear axis encoder, w axis
setp hm2_7c81.0.encoder.01.scale  -200        # this many pulses per mm
setp hm2_7c81.0.encoder.01.filter 0           # no filtering
setp hm2_7c81.0.encoder.01.index-enable true  # encoder has an index

INI file excerpt
#********************
# Axis W - this is the linear scale on the bed
# it needs a dummy joint
#********************
[AXIS_W]
MIN_LIMIT = -200.0
MAX_LIMIT = 200.0
MAX_VELOCITY = 10.0
MAX_ACCELERATION = 50.0
LOCK_VELOCITY = 0.0
LOCK_ACCELERATION = 0.0

[JOINT_1]
TYPE = LINEAR
HOME = 0.0
MAX_VELOCITY = 100.0
MAX_ACCELERATION = 500.0

# axis will appear homed immediately
HOME_SEARCH_VEL = 0.0
HOME_LATCH_VEL  = 0.0
HOME_USE_INDEX  = NO
HOME_SEQUENCE   = 0

FERROR = 99999.0
MIN_FERROR = 99999.0



Any thoughts?

Thanks,
Greg
