Many times Google translations from technical Chinese make no sense. A simple example I see many times is "pressure" used to mean volts. This is a sign that Googel Translate was used. A bilingual human with an education in electronics would know to say "volts" But Google does not know which interpretation of the character to use. The problem is that can't invent new characters, so the same written characters have several different meanings and you have to know the context to sort it out.
My wife has 8th grade education in Chinese. Enough to read newspapers, watch TV and read most fiction. But if I ask her to look at some data sheet that is in Chinese, she says "it does not make sense" It is written in a way that engineers have to learn. I think this is one of those cases. The "circular soft algorithm" is likely a really bad translation. And it might mean "loop" or "cycle" for all we know. They say it runs on Linux. I doubt anyone would write a CNC controller from scratch. What else might it be based on? BTW, the company also sells a real clean looking "A + B" smiling axis that has two rotary joints with 50:1 harmonic reduction and stepper motors. Who knows how well it works but it looks nice. Price is too high for me, I'd rather build one. This is a nice design to copy. See how the 50: reduction is integrated with the frame and to bolted to the frame. amazon.com/Dividing-Rotational-Indexing-Harmonic-Reducing/dp/B09WLCTLCX <https://www.amazon.com/Dividing-Rotational-Indexing-Harmonic-Reducing/dp/B09WLCTLCX/ref=sr_1_9?keywords=cnc+a+b+axis&qid=1673333303&sr=8-9> On Mon, Jan 9, 2023 at 8:08 PM Thaddeus Waldner <thadw...@gmail.com> wrote: > 8) Interpolation Algorithm: S type, circular hard algorithem, circular > soft algorithm: > > I wonder what is meant by interpolation algorithm. > > > On Jan 9, 2023, at 9:52 PM, Chris Albertson <albertson.ch...@gmail.com> > wrote: > > > > Amazon has a turn-keyCNC controller for $480.
