What rating or output is your PSU, if you dont want to change that as well then you need to match your drivers to that so they dont go pop!, consider if or not you plan to upgrade or use the new drivers on another machine in the future.

How about some of these: DRV30/S the tec doc is here for these as well.

Should be nice for a 4 wire bipolar motor, cheap, well made and very good support from Roy if anything was to go wrong.

Why are they better? are they not overkill for what he needs and his PSU being only 24v ? What about the duty if they get seen coming in?

Yes they are overkill but being overkill means they are not running flat out and plenty in reserve.
Plus they are in a case, post paid and cheaper.
That M542 design has been proved over many 100's of thousands of units built.

I have bought loads of these, none have ever hit the radar, usually they get declared as a USB cable at $10

What is Zone 1 and Zone 2 ?
It looks good but the circuits have no cases. So I would have to build something.

Are there no reliable "all in ones" ?... It just seems alot of accessories just for one job.

I can solder and repair boards at a push, but I'd rather just plug it into my pc/cnc , turn it on, and use it without all the whistles and bells. Maybe I am just lazy ?
