Hello everyone,First of all, Meister, I’d like to congratulate you on this amazing work.I decided to use this project on my machine. I made some adjustments to use the TangNano9K with an RPi 5 over SPI. I currently have two LEDs connected to the TangNano9K, and for now I just wanted to start by turning them on and off.I configured everything through the Setup-GUI, then generated, compiled, and flashed it to the TangNano9K. I also compiledusing halcompile. After that, I ran the test GUI from Setup-GUI, selected SPI communication, and was able to control the LEDs successfully from that interface.However, when I tried to run and test my own configuration () with LinuxCNC, I encountered some issues.When the Axis GUI opened, I first pressed the E-stop button. After pressing it, I received several consecutive "USRMOT: ERROR: command timeout" errors. Then I opened HAL Show and tried to change the LED states from there. Although I could make changes within HAL Show, I couldn’t actually change the state of the LEDs in the real world.Where do you think the problem might be?

Warum brauch ich für die 7c81 ein usb-blaster?
Kann man nicht mit dem w5500 modul zugreifen und per mesaflash flashen per ethernet?

I just finished a massive rework of the enable/disable logic for controls!

The G code editor highlight line is updated by the current reported motion line from LinuxCNC. This is sometimes not the exact line that is being executed because of look ahead.

generell finde ich es pratischer die konfiguration am pc zu machen (VM mit Linux geht auch), dann könnte man auch den TangNano9k programmieren.

Für das ECP5 board brauch man den programmer (usb-blaster, der funktioniert auch am PI und die toolchan auch (arm64) )

Zum betrieb am RPI4 kann man SPI (Jumperwire kabel) nutzen oder en W5500 Ethernet-Adapter (~4-5Euro).

Dann musst du aber noch schauen was du ansteuern möchtest, also z.B. Stepper,
da wird es mit den dev-boards etwas umständlich.

Wie soll denn dein test-aufbau aussehen ?

Oder wenn du eine 7c81hast kannst du die auch nutzen, brauchst aber wie einen PC/VM + USB-Blaster zum programmieren.

Ok!

Aber was könnte man direkt nutzen ohne zusätzliche hardware? Direkt am rpi4?

Danke

The translation into English is:

"Is the 7I92 pin compiled as:

10 30 IOPort SSerial 0 TXData0 (Out)
11 31 IOPort SSerial 0 RXData0
?

The translation into English is:

"Do I only need this HAL configuration:

loadrt hm2_eth board_ip="10.10.10.10" config="num_encoders=1 num_pwmgens=1 num_stepgens=5 sserial_port_0=0xxxxxxx"

Or are there other settings required as well?"

I'm trying to decide on a connection for my satellites

Ethernet or Firewire Cables, 5V or 24V ?

* RJ45 is cheaper, but could be confused with Ethernet
* FireWire uses thicker cablesCheaper
* satellite boards can be built using 5V, but 24V is practical for many sensors and limit switches
* RJ45 and 5V are compatible with Mesa-SmartSerial (except for the firmware)

Does anyone have any ideas?

no, but you can see the new pins with:

halcmd show

Hello, I'm trying to clone this board. Do you have any HAL file references?

benötigt aber noch einen usb-blaster zum programmieren.

Screenshot of the settings page?
In the meantime, disable:
-auto volts
-void sense/void lock
-set the arcok high to 160V
-set the arcok low to 60V
-set VAD to 60-65%
-set the cut voltage to (in your case) 100V
-set the feed rate to 2000mm/m
-set the jog speed to roughly 2000mm/m
-press F9 to fire the torch
-press an arrow key to jog
-watch the LED's on screen for arcok/up/down
Material for testing, 2-3mm thick, current set to 40-60A
Make some test cuts, check the under side of the cuts for dross and how easy it is to remove it, adjust feed rate/ air pressure (only while air is ON) and cut voltage till you get nice clean cuts with little dross.

It has somehow to do with the enabled stepper motors. As soon as the drive gets the enable signal the pins don´t change anymore (viewed them in hal config). Wen i check with the multimeter, the signal seems to be switching between 0.2V an 24V correctly (both with stepper enabled/disabled). Maybe it is an issue with those cheap breakout boards ?

That is almost always an interference/wiring/grounding/shielding issue, and cheap BOB's with optocouplers are very slow so will limit speed a lot, the ones with input buffers should be OK.
But, 24V? What encoders are those?
Upload some pictures of the wiring here so we can have a look.
