KINGPRINT DRV8825 Stepper Motor Driver Module with Heat Sink for 3D Printer Rrerap Ramps 1.4 A4988 (Pack of 5pcs)

Got 5 for 15 bucks or so Work like a charm will be ordering more...

These work just fine. Remember to adjust the screw for what you need. If running for a long time keep a fan blowing on them or keep a few spares on hand.

Ive used 1 out of the 5 drivers so far without any issues. Initially my order was shorted 1 item out of the 5. I contacted the seller and they sent out the missing piece. Overall I would buy from the seller again.

Works fine on my genmitsu pro.

I bought a Bigtreetech SKR V1.3 and shortly after I bought these realizing I needed stepper drivers. I was only getting about half this distance for moves after configuring and installing Marlin on the SKR. Turns out when I configured Marlin I had just quickly referenced this page at a glance saw the familiar A4988 in the title, which is the default stepper setup in Marlin. After looking at the page more carefully I changed the stepper drivers to what it should be in the firmware (DRV8825) and this fixed my problem. Hopefully this review can save someone time.

Cannot beat the price but it does not do much good when 1 was no good from the begin another failed in 30 minutes and so far the other 3 seem ok at this point. I have had better luck with the A4988’s

No documentation make sure whatever you are replacing they are going in the correct direction as these are opposite of the ones you might be upgrading.

was pleased with this

UPDATE 03/21/2019 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.

Great DVR8825 drivers. Noticable difference in print quality on my 3D printer.
