Sorry I can not really help, but searching for infos on my Baruffaldi RH80 I found some infos in the internet that can at least help to identify Baruffaldi toolchangers and show some of the interior, nothing to technical- just pictures of a brochure. But might be potentially helpful for anyone searching for infos on his Baruffaldi TC:

Remora - Rpi Software Stepping Using External Microcontroller via SPI

Category: Computers and Hardware

As I mentioned. First I am trying to test it with a4988/drv8825 drivers. That's why I didn't loaded tmc5160 modules. Testing it in step/dir mode only

Remora - Rpi Software Stepping Using External Microcontroller via SPI

Category: Computers and Hardware

Hi, LinuxCNC is very capable of handling this configuration with 4 joints and a X Y Y Z configuration. Check out the config below for my 3D printer that has dual Z axes.

github.com/scottalford75/Remora/tree/mai...figSamples/hypercube

The two joints won't jog together until they have been homed. I've found that out the hard way...

PnCconf Mesa 7i96s PWM speed control OUTPUT_SCALE

Category: Driver Boards

Yes, but the pncconf spindle setup also works with other devices with fixed 10V or +-10V  full scale
(7I77,7I76,7I83 etc)

It really should have an additional field for potentiometer type outputs based on the card type
Maybe "Full Scale Analog Output" and "Voltage For Maximum RPM" or some such

PnCconf Mesa 7i96s PWM speed control OUTPUT_SCALE

Category: Driver Boards

Thanks PCW! The quick reply saved me much head scratching. I will admit that I find this area of the setup a little confusing. Isn't the Mesa 'Spindle Out' voltage fully defined by the input Spindle+ and Spindle- values? Given a potentiometer wiper can never have a voltage higher than its input, what is the need for specifying the 'analog Max Voltage' at all?

Yeah I've seen it before, I believe it's a bug with the version of Mesa you're using.
Compiling a new version of mesa with panfrost would likely solve it.
Otherwise I'd suggest to take a new Armbian image and install the 6.1.115 kernel from: drive.google.com/drive/folders/1sPtbXDfx...WCB8o-ur0CINmMNvcjTQ

With the overlay "opi5plus-fixedfreq-undervolt.dts" it has a very low latency. You only need to remove the "-plus" at comparability and after that install it with "sudo armbian-add-overlay opi5plus-fixedfreq-undervolt.dts"

PnCconf Mesa 7i96s PWM speed control OUTPUT_SCALE

Category: Driver Boards

Its because pncconf assumes that the PWM full scale is always 10V so if you specify 5V
Is sets the scaling so that you would get 5V (1/2 of full scale scale) at 18000 RPM.

Just leave the "analog Max Voltage" at its default 10V

PnCconf Mesa 7i96s PWM speed control OUTPUT_SCALE

Category: Driver Boards

I'm setting up my machine and 7i96s using PnCconf and have had some issues with the spindle speed control. My VFD expects an analog 0-5v signal for speed control, i.e. 0v stopped, 5v 18000 RPM. It is open-loop, no spindle encoders. The motor has 2 poles and the drive frequency at 18000 RPM is 300 Hz. When I generate my .ini and .hal files with PnCconf I get the following in my .ini file.
[SPINDLE_0]
P = 0.0
I = 0.0
D = 0.0
FF0 = 1.0
FF1 = 0.0
FF2 = 0.0
BIAS = 0.0
DEADBAND = 0.0
MAX_OUTPUT = 18000.0
OUTPUT_SCALE = 36000
OUTPUT_MIN_LIMIT = 0
OUTPUT_MAX_LIMIT = 18000

With these settings, when I specify a speed of 18000 RPM (M3 S18000), I'm seeing less than 200 Hz on the VFD display and the spindle seems slower than I expect. Looking through the forums, I see most examples have OUTPUT_SCALE=MAX_OUTPUT. Sure enough, when I change the .ini file and set OUTPUT_SCALE = 18000, and command the spindle with M3 S18000 I get 300 Hz on the VFD display and a higher speed at the spindle. Can anyone explain what is going on here? Have I done something foolish? Any ideas on why OUTPUT_SCALE is configured as 36000 in PnCconf?

Can the OPI5 be Configured to Run LCNC?

Category: Computers and Hardware

Hello everyone,
I installed linuxcnc 2.10 on orange pi5 - with armbian + rt-kernel 6.1.75. The system was made a year ago, and I installed linuxcnc 2.10 now with old versions of dependencies, to keep the 3D acceleration functional.
The problem is that at startup I get the error:
python3: ../src/mesa/state_tracker/st_texture.c:73: st_texture_create: Assertion `height0 > 0' failed.
/usr/bin/linuxcnc: line 1005: 24283 Aborted $EMCDISPLAY -ini "$INIFILE" $EMCDISPLAYARGS "${EXTRA_ARGS[@]}"
Does anyone have an idea if it's a bug in linuxcnc, or the error appears as a result of a conflict?

Having issues calling ACTION.CALL_MDI() from python handler

Category: O Codes (subroutines) and NGCGUI

linuxcnc.org/docs/stable/html/gui/gladevcp-libraries.html

I don;t see anything you have done wrong.
The status library seems not to be able to poll.
Is linuxcnc running when you ran the glade panel?

This might be useful too:

Remora - Rpi Software Stepping Using External Microcontroller via SPI

Category: Computers and Hardware

Hi!
So the cnc is now moving and it was the SPI cable shielding!!! Thank you Scotta and tommylight!!!

But now we have another, issue, we are using 2 stepper motors for the Y-axis each of the stepper motors is connected to one stepper driver and we have the config setup in a way so that joint 1 pulses both, but that doesn't seem to be happening, only on Y motor moves, and the x axis moves as well, the z axis actually just doesn't move at all.

Is that the config file you have loaded? There are no TMC5160 driver configuration in your config. For each stepper you need to load a stepgen, as you have done, as well as configure the TMC driver. I'll share a config over the weekend.

Step By Step Help Needed . EL8 Leadshine to PI 5

Category: EtherCAT

Hi Shemj,Thank you so much for your help with getting the EtherCAT drives set up! Following your guide, I’ve successfully managed to connect all three drives, and they’re now running with the Probe Basic interface. The only step left is calibrating them to get the correct mm/rev on each axis.I’d really appreciate some suggestions on how to connect the spindle drive:
  • Current setup:
    • The machine’s three axes are using EtherCAT, connected through a daisy chain of Ethernet cables.
    • The spindle came with a 1.2 kW generic Chinese servo motor and drive, which has a 15-pin RS-232 serial connector.
  • Questions/options I’m exploring:
    1. Using Beckhoff hardware:
      • I have a Beckhoff EK1100. Could this be used with the appropriate module to control the spindle servo drive?
    2. Using a Mesa board:
      • Would connecting a Mesa board to the Pi via a USB-to-Ethernet adapter work, or would that introduce unnecessary complications?
    3. Alternative hardware setup:
      • Replace the Pi 5 with something like an Odroid H4 (dual Ethernet ports). That way one port could handle the Mesa board and the other the EtherCAT drives.
    4. Replacing the spindle drive:
      • The supplied spindle drive is an XCSD-20A from cncservocontrol.com. Are there any EtherCAT-compatible alternatives that would work with my motor?
  • Motor details:
    • Model: 80ST-M04030LBP
    • Power: 1.2 kW
    • Current: 5.2 A
    • Voltage: 220 V
    • Torque: 4.0 N·m
    • Speed: 3000 rpm
    • Encoder: 2500 PPR
If anyone has advice or suggestions on the best approach to integrate the spindle motor/drive, I’d be very grateful!
