7i92M very weird communication problem!!!

Category: Installing LinuxCNC

If there was no communication, LinuxCNC should exit.

Are you saying LinuxCNC is running but you have no activity light
(green LED on 7I92 RJ45)?

What does:

ip a

report when in this state?

Read value or file in G-code

Category: G&M Codes

Hello, I want to use QtDragon to determine the tool height using Utils - Workpiece and then save the result so that I can access the value in the G-code. My idea was to save the result to a file, which also works by slightly modifying the auto_height.py file. I added the following line:

def show_result(self, data):
        diff = float(data) - float(data)
        self.lineEdit_height.setText(format(diff, '.3f'))
        # New line by me:
        with open('/home/dg/linuxcnc/nc_files/probe_height.txt', 'w') as f: f.write(str(diff))

But how can I access the value stored in the probe_height file in a measurement routine.ngc, or can I save the measured value directly in
the G-coder as a variable, e.g., #5000

LinuxCNC with RIO (FPGA) SPI Issue: Unexpected 'HXHP' Response

Category: General LinuxCNC Questions

you need a clock of min. 10Mhz for the ICE40
Error: PLL input frequency 5.000 MHz is outside range 10 MHz - 133 MHz!
the cmd: '
gpio mode 7 clock;
gpio clock 7 5000000'
will generate an
18Mhz clock, not 5Mhz, don't know why


than you need to set the osc value to your new clock speed in
riocore/boards/IceShield/board.json
"clock": {
"osc": "18000000",
"speed": "29812000",
"pin": "35"
},

you can test the spi connection with the rio-test tool:
bin/rio-test riocore/configs/IceShield/config.json
i think to have the gpio commands you need to install WiringPi:
github.com/WiringPi/WiringPi/releases/tag/3.0

sorry, can not test it at the moment

Entwickler für eine Programmierung einer angepassten CNC Software auf LinuxCNC

Category: Deutsch

Guten Tag zusammen,wir sind ein Maschinenbauunternehmen aus Norddeutschland und suchen einen Partner, der uns bei der Entwicklung einer CNC-Software für ein Bohr- und Fräszentrum unterstützt. Die Software soll auf LinuxCNC basieren und eine eigene, individuell gestaltete Benutzeroberfläche mit verschieden Features erhalten.Das beauftragte Unternehmen sollte die Erstinbetriebnahme übernehmen und einen langfristigen Support sicherstellen können.
Ein Lastenheft mit den Anforderungen an die Software liegt bereits vor.Bei Interesse an diesem Projekt freue ich mich über Ihre This email address is being protected from spambots. You need JavaScript enabled to view it.
