Remora - ethernet NVEM / EC300 / EC500 cnc board

Category: Computers and Hardware

That's it, I'm now able to generate steps up to 125KHz !
You were right, using the DMA version did the trick !
I'll check the posts talking about DMA.
Again, thank you royka

EDIT:
For those wondering, the 125KHz limitation comes from the step length and step space both set to 4us. F=1/T so F=1/8us=125KHz everything works out !
The limitation comes from my JMC Integrated Servo, they don't work is I lower the step length.
That's kind of weird because the datasheet claims they can go down to 2.5us...
I'll check the signal with an oscilloscope.

Yes that one was the default. I just switched to the one Phil provided. Was able to run the materials in QTPlasmac but I seem to have an issue in Height control or maybe it was the consumable guess ill check that real quick...
Ok those look good but I'm getting intermittent raised cuts probably a settings issue in my HC but I've seen some PP create issues there as well. Im using the MESA THCad2 so its more than likely I haven't dialed that in correctly yet.

THCAD2 - HF start will kill it?

Category: Plasma & Laser

Thank you guys, I connected before the choke coil, there are 3kV capacitors so the voltage can't be higher than that. I used HV resistors.

Now I'm stucked with the arc voltage.
I placed a 9V battery on the input with a potmeter to test it. I set and calibrrated everything, encoder.0.velocity net to arc-voltage-in, the value changes with the pot but the arc voltage on the GUI and arc-voltage-out signal does not change, stays zero. Tried different scale settings, no result.
How to get that voltage?

Seems like you’re still using the default post processor instead of the one Phill posted…
