They are not less noisy than the drivers that came with my RAMPS board. I still hear plenty of hissing, grinding, and clicking sounds with most motors. I don't know if the problem exists at higher voltages but my RAMPS board is limited at 12V (I didn't do the power supply mod). I attempted to run some of them at 24V in a breadboard, but they weren't any quieter that way either. I have larger power supplies for CNC machines I might try, but in my experience, a noisy stepper driver is always noisy.
I also saw stalls and missed steps with all but a few of my motors, and for this reason I stopped using these drivers and put the old Pololus back in. Maybe it's a setup issue, but the "cheaper" ones I was using worked better no matter what I did. I actually found it difficult to force my old drivers to stall, unless I deliberately turned the current too low. I would rate these drivers four stars if I could find one or two motors that reliably work with them.. but out of hundreds in my collection, I could find none. I can prevent stalls by limiting max and min speed and acceleration, but after doing so the system was no faster than with the original drivers, which I was able to "overclock" modestly. I don't think making my printer faster would help anyway, because it's already limited in speed by print quality and heater capacity.
I have a personal suspicion that there's a "sweet spot" in motor inductance for these kinds of "cheap choppers." Lots of common surplus steppers made for low-voltage use have high inductance, which makes these drivers slow to react and limits torque. Above a certain limit, the current never reaches the setpoint. Higher-torque motors can have too low an inductance, too, which also causes problems because the chopper oscillator runs at maximum speed and the driver can't accurately measure torque/current. If you spend a lot of money on a driver, you get a more versatile oscillator and more sensitive current-measuring, and that's where I think these things fall short.
That said, however, my issues were mainly with the plethora of motors I've scrapped from lab equipment and old printers, and I didn't do extensive testing with current-era 3D-printer-size steppers (tho I did use a 3D printer mechanic for some of it). I need larger modular drivers for what I'm doing. You may find that these work great in your application, and at the price, you can probably afford to try them out.
New Title says it all.
Arrived early February and installed in a RAMPS board, set to 0.82MV and all good. Well, all good for about 16 hours of printing anyway. Just pulled them all out and have gone back to the A4988 after the second one failed. It is a pity as they quietened the printing down a lot with the 1/32 Micro-stepping.
I am a bit surprised as I am a fan of Kingprint with with several main boards that have proven to be exceptionally reliable, but this latest batch of drivers -- not so much it seems. This is the second batch of DRV8825 I have had from them. The first lot bought in mid 2018 have been excellent and still running reliably.
Will order from a different supplier and try again.
These might be okay drivers for those who know them well, but if you're a first time user of these like me I say AVOID!
