I opened up a drive and the PCB has markings of DM556 V2.2 on the bottom of the board.
Looks like they (Primo?) added a 0.6ohm resistor from the high voltage stepper power plug positive terminal to ground to act as a voltage divide, lowering the actual voltage getting to the drive. The only place the PCB has solder flux residue as well is on that resistor. I assume they then changed the cover to make it look like a DM856.
I contacted Leadshine USA, and they say that the DM856 should not have DM556 markings on the PCB and that PrimoPal is not an authorized re-seller and I'm on my own.
I advise everyone not to buy from these guys, even though they have 100% satisfaction rating.
Sad for a first post.
