Re: Introducing new DIY hobby CNC controller project TOAD4 / EazyCNC
Very nice if you want to be stuck with Windoze? Also not very cost effective if your at the cheaper end of the CNC market. I think EasyCNC at least addresses the first dabble into it. A bit like the educational type machines did for schools.

Jonathon,
Don't know where you are getting 11kHz from.
The manual says the 6560 driver chip is limited to 15kHz
**********************************8
The chips voltage supply range is from 6 V up to 40 V so the board can be used (with some
trivial component changes) down to 6 VAC and it might be possible to push it close to 40 VDC
giving some more drive capability for higher inductance motors, but that will require a better
regulated power supply so as not to exceed the 40 V under any circumstances.
The other limiting factor of the chip is it's 15 kHz step clock maximum which limits the step
rate to 3750 steps/sec using full step or 950 steps/sec with micro stepping. With a typical 1.8
step angle or 200 steps per revolution of common hybrid steppers this translates to about 19
r/sec or 1100 rpm and 4.5 r/sec or 280 rpm, respectively.

This page from the first post:
About EazyCNC
It says:

Four identical stepper drivers:
...
up to 11 kHz step frequency'
Interestingly the next paragraph from the document you read says 5kHz!
Quote:
In practice the microcontroller and its firmware can be the limiting factor and it maybe be
hard to push the software generated step clock rate above 5 kHz. Fortunately most applications
are likely to require much slower speeds.
So it might be 11kHz, certainly not more than 15kHz with TB6560 and might be just 5kHz. I think we need clarification from the member who started this thread...
Re: Introducing new DIY hobby CNC controller project TOAD4 / EazyCNC
My understanding is that this is to be "project" in kit form, which implies that it will come in at a better price than anything currently on the market. If successful I think it could be a bonus for many new builders, and may well lead them (EazyCNC) to introducing a higher specified version at some future date, maybe higher A/V, digital drivers - and any other bells and whistles etc. Surely a move to usb can only be the way to go forward in the long run.
I hope that this venture will prove to be affordable and successful. G.
