I certainly don’t wish to discourage any attempt to speed up AccelStepper. Well, it’s been 4 months and the cupboard is still missing but we have a great CNC driver to share with everyone: Indeed, I have thought about it – however to run a DDS style setup requires regular interrupts – AccelStepper needs no interrupts, so its forced to do more calculation – its can’t rely on being called at a regular rate. Estimated delivery Jun Shipping in June and August! As previously mentioned we have evaluated many fab house to find the best value to pass on to our Backers. All they need is a succession of step pulses at appropriate intervals.

One of the main focuses of this board was creating an extensible platform for future development or hacking.

If fabrication becomes an issue we will work with multiple houses to get the orders done right and on time. Dayton, OH Fabrication Tools. Read times previous topic – next topic. We wanted 4 motor drivers to allow dual motor configuration for the X, Y, or Z axis or the ability to run as a 4 axis machine.
Stepprr Brattain Member Posts: We have worked very hard to minimize any potential hiccup. Early Bird Bonus Round: Shipping in June and August! It’s meant to be a CNC board, but for my purposes I’m running three stepper motors independently with real-time control.
Indeed, I have thought about it – however to run a DDS style setup requires regular interrupts – AccelStepper needs no interrupts, so its forced to do more calculation – its can’t rely on being called at a regular contrkller.
If you feel like being crafty you can now connect your xPRO to your Smartphone and have all kinds of fun! May 30, – Jun 22, 23 days.
However I wonder if it is currently written to be very flexible as the user can select a wide variety of acceleration rates. MarkT Brattain Member Posts: I assumed it was using some sort of PWM signal based on Timer0, 1 and 2, but A it can actually drive FOUR motors at a time while there’s only three timers on the UNO, and B most of the controllwr on stfpper forum insist that PWM is a bad way to control steppers as there’s no way to count steps.
We worked with many PCB manufacturers to find one who could deliver consistently and without breaking the bank. Let the fun begin!
We set out to create the only CNC driver anyone would ever need. Looks like optimizing accelStepper would be a useful project.
Now that is interesting.

Kickstarter is not a store. To do this we needed a single board solution fully extensible for future development. Get everything you need to build the Zeus CNC router in one weekend!
Support Select this reward. Gotta Have It All: Here is a look at the schematic for this board. On finishing the hardware fabrication we started looking into electronics and found very little that fit our budget and desired capabilities personally I have never been a huge controllsr of shield stacks for final products, or wiring two motors to one driver.
The GRBL developers took the trouble to make their code as fast as possible. All they need is a succession of step pulses at appropriate intervals.
Time to brew some coffee. I don’t have direct measurements, but GRBL runs my steppers much much faster than that.
