LinuxCNC installation + 7I96S

1. you are selecting stuff you do not need, like parallel port
2. might also be the "locale" thing where the wizard has issues with other languages than English.
To test, boot the PC from the USB you used to install LinuxCNC in LIVE mode, use the wizard to make a new configuration and save it to hard drive or another USB, then reboot to normal install and test the config.

Open the hal file attached at that link, somewhere lower in the thread, it is named Graveri kuq as zip file, compare your hal to mine till you get it working, then add the safety stuff with some signal names in Albanian.

Would it be possible to download the INI and HAL files for my Mesa and LinuxCNC version?

I have made many configurations and I still cannot control the machine.

I’m on that topic (at the same time I express my admiration for the design shown there) but I didn’t see anything on my question. 
Clearly I'm doing something wrong in the hal file.

But what exactly?

Have a look at this, there is also the complete config attached there, it is the same thing as laser as it uses PWM to control the grinding bit pressure, and it also should have provisions for turning off the laser when canceling or pausing or stopping a job, that is normally not done with normal configs.

Repair Servodrive Yaskawa CACR

Category: Off Topic and Test Posts

        ​Hello everyone,​I'm working on repairing a Yaskawa CACR-SR20BE12G-E servo drive. I initially had to replace all the capacitors as two of them had incorrect values, which was causing the A.02 error. After installing the board, everything worked fine for about 30 minutes, but then the auxiliary power supply errors A.03 and A.40 appeared.​I've isolated the critical components after the transformer T3076, specifically D20 (code C3) and AVR4 (code 8C E4), which now appear to be faulty.​I need help confirming the identity and replacement parts for these components.​1. D20 (Code C3) - Raddrizzatore Schottky​I have traced the pinout of D20 and have the following connections:​CENTER PIN: Connects to the positive pole of capacitor C41 33uf 25v​TOP LEFT PIN: Connects to the transformer output, passing through diode D32.​RIGHT PIN: Goes to the negative side of the board (or where the letter 'N' is marked).​Question: Can anyone who has successfully repaired this confirm if the correct replacement is indeed the BAT54C (Dual Common Cathode, SOT-23)?​2. AVR4 (Code 8C E4) -​dimension(approx. 3x2mm). The marking on my faulty board is 8C E4, while a known working board shows 8C E8 (I assume the last digit is just a batch code).​Pinout/Measurements:​I'm using the following numbering: Pin 1 (Top Left), Pin 2 (Center), Pin 3 (Top Right), and Pin 4 (Bottom). Note that Pin 4 is common with Pin 2 on the board.​Using the diode function on my multimeter:​Black probe on Pin 2 or 4, Red probe on Pin 1 or 3 Reads 2.3v- 2.4V​Inverting the probes Reads 0.5 - 0.6V

Can you help me please?

Secondary PWM Output for LASER

Category: Advanced Configuration

Good afternoon colleagues.
I ask for help connecting the laser to the machine.
My machine works properly without LPT. Scheme XXYYZ. This is five motorcycles. And a spindle. The spindle to the 14-pin LPT port is such a feature of the controller.
I read topics -
forum.linuxcnc.org/10-advanced-configura...pwm-output-for-laser
forum.linuxcnc.org/plasma-laser/32691-settings-from-g-code-file
forum.linuxcnc.org/10-advanced-configura...er-control-using-pwm

From what I read, I understood the following - 
1. from the g-code file, control the status and power of the laser using the M67-M68 commands
2. the main thing is that the correct configuration must be made in the machine settings file 

My PWM laser is up to 20kgz. 

I'm trying to add the following lines -
loadrt pwmgen output_type=1.0 #1 this is for Spindel, 0 for Laser

...

    #net spindle-pwm     => parport.0.pin-14-out
    #setp parport.0.pin-14-out-invert 1
    net spindle-cmd-rpm => pwmgen.0.value
    net spindle-on <= spindle.0.on => pwmgen.0.enable
    net spindle-pwm <= pwmgen.0.pwm
    
    #setp pwmgen.0.pwm-freq 100.0
    #setp pwmgen.0.scale 15000.0
    #setp pwmgen.0.offset 0.133333333333
    #setp pwmgen.0.dither-pwm true
    
    net spindle-cmd-rpm     <= spindle.0.speed-out
    net spindle-cmd-rpm-abs <= spindle.0.speed-out-abs
    net spindle-cmd-rps     <= spindle.0.speed-out-rps
    net spindle-cmd-rps-abs <= spindle.0.speed-out-rps-abs
    net spindle-at-speed    => spindle.0.at-speed
#лазерный блок
#addf pwmgen.make-pulses base-thread
  #  addf pwmgen.update servo-thread
    setp parport.0.pin-14-out-invert 0
    setp pwmgen.1.enable TRUE
    #setp pwmgen.1.pwm-freq 20000
    net analogout motion.analog-out-00 => pwmgen.1.value
    net laserpwm pwmgen.1.pwm => parport.0.pin-14-out
        

doesn't work. The laser is not turned on by the M68 E0 Q 1 commands

Please tell me what I'm doing wrong? And is it possible to use the same pin 14 (I physically turn off the spindle or laser) for control?

Glade Hal Meter Spindle Speed -> postgui

Category: GladeVCP

Hello,
iḿ still a beginner with glade and today i wanted to add a Hal Meter in Glade that shows the spindle speed. 
Things i did so far:
- I found out that i minimum require a float signal (maybe that on the picture attached?)
- i created a Hal Meter in Glade -> see attached file

I tried to add the call for gladevcp.Spindel in my machine.ini but didn't realize that Glade starts after the machine.ini

My next step was the postgui.hal
net Spindelrpm =>  gladevcp.Spindel <= spindle.0.speed-out
Error --> custom_postgui.hal:9: Pin 'spindle.0.speed-out' was already linked to signal 'spindle-vel-cmd-rpm'

Yesterday i learned that if a signal is linked i can´t use it.... but from here i don´t know further

Please help

Why are there 3 2.9.2 ISO files?

Category: General LinuxCNC Questions

Keep only the latest ISO and maybe the Wheezy for users of parallel port machines, delete everything else.

 Hey CNC4Life,

I can't find your project - I think the link is dead.
Can you post it here?
Here is my INI...Currently, the reference process starts, and I am at pocket 1. Then I want pocket 5.
The carousel goes to that position, but when I want to go back to tool 1, the carousel rotates in the same direction (so I end up at a pocket with a higher number).

The carousel.comp  ignores the parameters for unidirectional and reverse pins.

I think there is a problem with the counts being given to the PID.

fixing "raspi firmware" errors on the official amd64 ISO

Category: Installing LinuxCNC

[code]--architectures amd64 \

is missing from auto/config file
[/code]

Does that remove anything else? The first thing that comes to mind is the hostmot2 firmware. (which I think is also "architecture all" )

Can you explain a bit more, I've created a file with parameters and changed them and ran the file and the parameters are updated without loading the file or reloading the file.

I'm new to cnc and linuxcnc in general. I'm trying to create a mesa 7i97t config file with Mesa CT but I don't see the option to use QtPlasmaC as the GUI. Is there any way to to this?
