YouTube will be lucky to buy you a carton of beer a month but if you use it to promote your business that can be a good business. You need a business plan to put it together... which means you have some hard thinking ahead!

The problem has been resolved after adjusting the parameters of `joint` and `pid`.

I apologize for asking so many questions.Strangely enough, the MESA7i92 which also has PID and  deadband, does not have output pulse count error. I'm a retired person in my sixties, and I only use CNC as a hobby now. I was so eager to ask because I discovered a problem with motor positioning. In my experience, I haven't encountered any open-loop pulse positioning errors with CNC controllers,so I only checked it with a logic analyzer yesterday,The number of pulses in an open-loop stepper motor must be absolutely accurate. Back in the early days of GRBL, I also found an operation that caused a crash, and I immediately notified the author. After confirming the error, he escalated it to a serious bug and fixed it( github.com/gnea/grbl/issues/238 )

Deviations may occur due to the PID controller and the deadband; these shouldn’t exceed ±1.
If you then also take measurements using pendulum movements without setting the G64 parameter, the difference may be even greater.

If you’ve got a logic analyser, why didn’t you use it earlier to measure the pulses?
And if you’ve got something like that, you must have a multimeter too, yet you still haven’t measured the voltages at the DIR pin.
This is a hobby project; I’m really happy to help, but there are limits – especially when you keep posting such fragmented information in the thread.

The only thing I can say is, yes, there are definitely 1,000 bugs in Riocore and a lot of things could be handled better.
I try to implement it as best I can; when bugs are reported to me, I try to fix them as soon as possible.
But if neither DIR nor Scale were working here, you certainly wouldn’t be the only one to report it.

I’ve no idea how many people use Riocore – I don’t think it’s that many –
If I keep coming across new boards from all over the world that have been built specifically for Riocore,
then I suppose there must be one or two people using them.
and the complaints seem to be kept within reasonable limits.

We used "BendDeduction" I think it was 5x material thickness or was it radius?

yep no stress.

Yeah, not possible, and not because of this or anything here, not sure if you bumped into a post some 2 months ago where i mentioned the government literally destroyed my business (paid for china machines for whoever applied for that grant) so now i have 5 or 6 new machines collecting dust and a new shop i have no use for.
I hate to say it, but i will have to become a youtuber or start training schools, be it online or live, ... or start doing flooring as this has gone from 2-4 euro per sq meter two years ago, to 11-14 euro now! And of course, i am bloody good at it, but .... oh hell no.

Whats confusing to me too, is that i cannot use 
"loadusr -W hal_input Code Mercenaries KeyWarrior Combo O Commander" , that one won't work, only without " , its accepted.
As far as i know, you should always use " when there are blanks in a name / path.

Try:

Disable "mesh" mode.

Have you enabled the THC in the GUI?

I measured 0.2mm using a logic analyzer, which is not 64 steps.Tang Nano 9k riocore ,leadscwer=5mm,driver= 1600step/revScale_Out=320 ,1mm/320=0.003125mm/step0.2mm/0.003125=64step

Das ist wahr fur diese:

Die normale eingange mit schraub klemen, da sind OK fuhr 36V

The isolated inputs on TB3 accept 4V to 36V signals.

Hallo tommylight,
vielen Dank, ich meine ich hätte gelesen das die Eingänge 5volt tolerant sind und einen Pullup-Widerstand hätten.

Hi do you still have all the old boards from the VK45?

Auf die Mesa 7i96 manual (niht 7i96S):

Hallo,
ich kann jetzt die Karte über Ethernet ansprechen und habe auch die 7I96_inmd.bit auf die Karte gespielt. Nur mal eine Frage für
die Zukunft: Gibt es eine Karte die so ähnlich wie 7I96 ist aber Eingangssignale von 24Volt verarbeiten kann?
MfG
