PoKeys57CNC HAL component

Hi all,
With Windows 10 getting slowly obsolete, and also since I also was not 100% happy with Mach4, I looked into LinuxCNC as an alternative.
I already found the other topic on the PoKeys HAL driver , however was not succesful getting Dominiks component to run.
Before reverse engineering that component, I thought to myself "how hard could it be?". I do not need many features for my setup.

Said and done, here is my own component to run a 3-axis mill: PoKeysMotionComponent on GitHub.
I still have some things in the backlog to do, but you can already use it. Hopefully it helps someone out there.
 

Thank you for giving back to the community, it's refreshing to see rather than those that just take take take.
A Tip O The Hat to you sir

Very interesting. I have a Pokeys here so am going to give it a whirl!

Any idea of the maximum velocities you achieved?

The theoretical limit of the Pokeys57CNC is 125'000 steps per second. Whatever this might translate to, depends on the machine.
My minimill has just standard screws and also smallish steppers, so I keep it on the slow side: 360mm/min => 6mm/s => 4'800 pulses/s
The problem with steppers is, for some smooth operation, you'll want microstepping, but then you loose torque. I added a belt reduction to "help" with the torque loss, but sacrifice speed again...

I don't think modern drives loose torque with microstepping. I ran 25x microstepping on my machines.....But yes I was considering how much microstepping I could use. Maybe 8x. Adding a belt reduction is often the wise choice.

Yes, I found the specs in the manual. Seems like you could increase velocities

This is very interesting. I recently purchased a Ozaki CNC lathe with mach3 control. I don't really liked the mach3 too much, but it worked well enough. Then my HDD crashed and this seemed to be a very good opportunity to go ahead and convert it to Linuxcnc...

But then, what about the used Pokeys 56U? Then I found this. Hope it connects with the 56U too, really good to find this.
