Halt stop, zurück

den TangNano9K kann man nicht vom RPI4 aus programmieren, dafür braucht man einen PC.

zum rumspielen ist denke ich, ist der TangNano9k ein guter einstieg,
im prinzip geht es auch günstiger, ber dann ist man extrem limitiert.

Aber es kommt immer drauf an was du machen möchtest, es sind halt nur dev-boards.

Ahaaa i have laying a 7c81... i use on my rpi4 a 7i92.

Other question

What is the cheapest fpga with which i can start? Can you recommand...

Ach qas laber ich hier auf englisch...
Was ist deiner meinung nach der günstigste fpga zum starten?
Stm32 black und bluepill hab ich... auch n radpberry pico usw..

Danke dir

nope, moving way slower than by hand. It´s not getting any position change at all, even with super slow acceleration/velocity

maybe the move is to fast or the resolution of the encoder too high for parport

Ok, I think I figured out why the label colors weren't changing. In Glade, I had a color defined in the label attributes. After I cleared that entry, then the color changing worked.

Now to work on my further modifications.

It worked for me in the virtual sim environment, debian 12, glade 3.4 installed and axis.mm sim. It was embedded as sidepanel. And the screenshots made when set example pin true/false. 

short version:

i put the ethernet cable in the rj45 socket

longer version:
i used the rio gateware and add an w5500 ethernet board to the spi pins:

 

Could you please explain how you connect the 7c81 via ethernet?

Hello,
i am currently stuck implementing a direct closed loop (2 axis lathe, parallel port, stepper motor, linear scale for closed loop).
The problem is: I do get the right position feedback, when moving manually (DRO display is correct) and i can see the correct encoder positions (in Hal-Scope: encoder.0.position). However, as soon as i try to move the axis, it starts to move and errors out with following error. If i look in the hal-scope, the "encoder.0.position" does not move one bit during the move (stepper is moving). 

--> Why does read out the position while idling but not while moving ?
Thanks 

When I tested the above code, it would change the text, but the color stayed black (no color changes)

Try with synctorefclock false, and see if your reset counter also counts up or not 

@grandixximo
Sync0shift is set to 300000

Note that LinuxCNC only supports Python3/Gtk3 from version 2.9.x so if you are using any custom python or glade code you would have to port those files to python3/gtk3.

In my opinion you'd be better off getting a second ssd and do a fresh install of 2.9.8 on that. Once you get that installed port your config files from the current drive to the new one.

Did you say you had changing values on pll-reset-count? That one should stay on 1, not increase.
Can you perhaps record pll-err in halscope and show?
