Hi Vez, just FYI, detent torque actually refers to the torque required to spin the shaft when the motor is completely unpowered. Whereas holding torque refers to when the motor is powered but not commanded to move. Detent torque is useful in situations where the motor can be constantly loaded, for example, the z-motors which have to always support the mass of the bed, even when the power is off.

Since no one said that until now, I'll say it: this motor is just LDO's version of the QSH4218-47-28-040 stepper motor made by Trinamic (yep, the same company that make the popular TMC stepper drivers). The specs of them both are really, really close if you look at both datasheets. Btw, companies should use Trinamic's datasheets as their guide, the sheer amount of information you can read on them is amazing, you can learn A LOT about stepper motors reading them. As long as LDO's motor prices are lower than Trinamic's ones (depending on where you look they cost from $60 to over $70 each. Ouch.), they look very promising.

Hi, Simon! Motors are very impresive! That low resistance and inductance just UNBELIVABLE! On 18:50 you printed this orange part with the Lines (Cura) or Rectilinear (Prusa) infil pattern, right! You have to try to increase the infill line width to 0.6 or even more. If the line width is lower that 0.6mm than your infill layers are not bonding to the layer beneath. With 0.6mm+ line width you will get solid infill - MUCH stronger!

That is interesting that motors makes additional vibrations at some range of speeds. Interesting to determine what speeds produce the least noise / vibrations. these are the 1st LDO motors I have seen that have connector plugs on the motors, Some motors the wires are physically wired in. Especially on small Extruder motors. This makes it hard to swap them out without rewiring the whole cable harness back the the control board.

Very nice for stepper motors in open loop, but you should be able to achieve the same results by using better drivers and higher voltages with almost any other stepper. As far as vibration at low speeds, look at the current waveform in the phases with an oscilloscope. I think you should be able to solve that problem by adjusting the drivers. I still prefer BLDC servos, or at least running hybrid stepper motors in FOC mode at ~96V. Edit: I'm getting 125m/s^2 acceleration with my 240V 180W AC servos, silent at all speeds, no vibration or artifacts at any speed. They have 17 bit optical encoders, showing maximum following error of 0.5° at peak acceleration and no following error at normal operating accelerations. I can further reduce that following error with additional tuning, but I haven't bothered because it's imperceptible as it is. The best part is I never have to worry about missing steps or input shaping and and all that. Since the load characteristics are very well defined and relatively static, the tuning is _very_ easy and everything works as expected.
