Ok I’ll make a note of that.
Thanks for testing.

Rando hal component collections

Probably here, as far as i can tell, everything else will inevitably lead to here, and google still seems to find the forum easily.

What do you think about a new subfolder?
  • Configuring LinuxCNC
    • HAL
      • HAL Examples
      • User-written HAL Components
Maybe with a sticky at the top explaining what the deal is - i.e. non-mainstream HAL components that may or may not do what you want.

​​​​​​​If we just have a single thread called 'HAL User Components' it will instantly get polluted with random comments, tangents, and questions on how to use the component(s).

A sub-folder might help keep it clean(ish) for a little while.

I just half wrote one here on the forum tonight forum.linuxcnc.org/49-basic-configuratio...-brake-with-linuxcnc
Blink could be improved a lot by using fperiod() so the on time and off time was specified in seconds if anybody wanted an intermediate project to practice on. :)
 

Well in the post the guy says it requires a floating point thread, but it is a nofp component, so you'd assume it was intended to run in a base thread.

My flash component started off with a counter, but wasn't very accurate timing. I'm using fperiod now, much better.

I say "my" component but really chatgpt wrote it lol. The nuances of comp trip it up pretty hard but you can get through it.

@ vpomerleau, you may have to bypass the opticouplers on the board if it's over 2.5khz. rbobey1989 has a post in this thread about it.

If I ever manage to get mine going. I'll document what I did and what opticouplers to bypass etc

The pulse turning it by hand seemed good. Anything over about 150rpm the pulse was distorted , it was an open collector npn 500ppr

What was the part number of the original encoder?

If it was an open collector output, was your pull up resistor to high a value?

Did you look at the pulse train with a scope?

@Mudrat, I thought it was noise I was experiencing. But when I took the encoder apart I found it was a magnetic pickup instead of optical. It lost pulses above 200rpm and stopped counting. All omron e6b2 encoders have a dual board with disk inside. This was a single board. Pic below what it's suppose to look like inside(don't know if it genuine or a good copy)

Murphy, your picture shows a magnetic encoder, not optical. The Omron e6b2 encoders have 4 different versions, with different voltages and polarity.
If it is a direct copy then your index pulse is on the orange or orange/orange with red stripe depending on version.
