OK cool, thanks for that, I think I'll try it out. The tangnano is doing the job nicely so far but runs out of pins quickly when you include 4 axis closed loop with index pulses.

Yes there is a mux4. But then you will one have 2 selction bits and he needs three. Assuming there is a fourth state where nothing is active otherwise mux4 is doable I would say.

in the near future. The stepper-ninja hal driver run in the servo-thread so the minimum width of one input is 1 servo thread refresh in length, with 1KHz servo-thread its 1mS, something like this: when you see a ruler, all 1mm division represents a servo thread cycle, the signal only starts in the divisions and only end on the divisions. With low spindle speed its probably working, but if you want better threading you use printer port for the lathe spindle encoder.

only the onboard mii chips do not run, the w5500 runs with all boards and toolchains.

the programmer on the additional board is very slow, better use a USB blaster to access the JTAG pins, it works great with openFPGAloader

I would prefer the i5, it has the ECP5 on it and is best supported. It's also so big that you won't get it full

 Hallo,
I tested the new version today and noticed that when I round the corners P64 P10.0 the speed of the axis (joint) does not behave as expected (yellow circle).
The acceleration (green circles) is interrupted by (blue circles) whereby the change in acceleration (jerk) appears to be too large.
At P64 P0.0 the axis (joint) behaves as expected.
Can this behavior be set via parameters?

Hello,

let check this topic  ... It will be in the general 99% same as for CanOpen setup.. but datas config should be little bit different...

regards E..

I have never had issues mounting the THCAD inside the control box. The plasma has a CNC interface connector so its designed for this.
You will not have issues.
