@David_Cutting You are right about that. the price of those are not most expensive i looked step servos from internet and the price was more than 200$ compared to those 60-70$ is not so expensive. And with those you don’t need need the stepper drivers. And like all new more you get revenue lover the cost goes in long run. So i hope you get interested people.
@Ulrich_Baer there will be no gearing. Because it’s a servo and has position feedback you can apply full torque at low speeds.
@Jukka-Pekka_Ylitalo thanks… my pricing is based on quantities of about 1000 motors
Why did you not just say that you wanted to incorporate a digital encoder within an NEMA17 motor?
@Brian_Link this motor is brushless instead of stepper.
Your pricerange is a lot above my ‘let’s see if this works’ amount. It is not clear to me how this is better than good steppers and good drivers?
@Jelle_B the advantages are the closed loop feature, higher resolution, and decreased noise. I just plugged in a demo unit for the sample controller board that I have from my partner company and it makes very little noise. I’m pretty confident that you could sleep in the same room as the printer with no problems. The communication protocol is also nice because it allows you to hook up many motors to a single controller board as long as you have an I2C line.
But then, is it four times as good? What firmwares can work now with I2C drivers anyway?
The motors are capable of running on step/dir, UART, or I2C. The step/dir is already available on all boards and I2C is available from expansion ports on others. Firmware-wise, I can foresee the possibility of customizing existing firmwares with I2C…
The existing step/dir ports could be set to a 64 or 128 microstepping mode in the firmware, and that will give you the required resolution.
