What kind of speed can one expect from this chip? I am using an Applied Motion HT17-075 nema17 motor and have everything setp-up for real smooth and quiet operation but anything above 900 steps/s generates noise, vibration and loss of torque.
The same steppers, when driven with other drives can go really faster.
I am using the 128 micro-step mode (have stried even full-step with no difference) and am driving the whole thing with 24v.
Form the motor specs and measurements I have the following data:
phase current 0.85A
phase resistance 6.6 ohms
phase inductance 12mH
measured Ke 0.0475 V/Hz
Can anyone spin their motors faster? what kind of settings are you using?

Saw it! Thank you VERY much!
A real soldering station is on the way at last!
Can we know in advance whether the order qualifies or not? Maybe in the checkout section?

For people looking for Windows 7 64bits driver, I recommend looking at the following (and oddly similar!) scopes:
lecroy waveace 112
BK Precision Model 2532B (I’m currently using this one)
Need to stock to the EasyScope supplied by Atten though.
No public wish lists :(
