Does anyone here have any experience with 5 phase steppers?
I bought a linear actuator, because it had everything I needed for a new Z-axis, but wasn't counting on getting the motor along with it. The motor is a REALLY nice Vexta PK544-BA motor, with a built-in encoder. The axis itself is equally nice, come to think about it, and has integrated optical endstops and mounting points for hardware as well as to mount the axis itself to a larger device.
Anyway, this motor is ABSURDLY accurate, apparently, so I'd MUCH rather use it than a regular stepper. Does anyone have any idea how to make a driver for one of these? Or where to get one cheap? Or even where to get one that will interface with NanoDLP or GRBL?
Happy to post pictures for anyone who wants them.

You need to change your driver from drv8825 to something else. As I know some of the Trinamic drivers supports 5 phase steppers. Usually they provides same step, direction pins to connect to nanoDLP or GRBL.

On the off chance anyone wants to know, I can't find a single driver for a 5 phase stepper that takes step and direction commands.
So... that's a dead end.

I found that, I even sourced the 16 pin SSOP package that I can hand solder (rather than having to deal with a BGA). I don't have a circuit for it. I don't know how to put it together, or what support circuitry it needs, or literally anything about it at all.
If you can help me out, that'd be amazing.

I hoped for a driver which use this chip. I could not find one. But here is another one. It is quite costly.

Yeah, that's WAY too much, and I can't tell if that controller takes step / direction commands anyway. I've given up on that motor. I replaced it with a standard NEMA17 whatever MicroCenter carries on the shelf. I've set it up with an EasyDriver 4.4 in full step mode, and with the 1:1 coupler and the way the leadscrew is pitched, my consistent 100% stable layer height is 0.006mm in a single step.
Long story short, I'd have REALLY liked to have used that motor, but it's not worth worrying about when what I've got so clearly still works.
On to other things.
