It's begun....

Thanks as ever Dean,

I could probably do with another Driver in any case, so will add that to my order with Zapp - will have to see if the 806-5 transformer will be good for a 4th Driver or I'll have to get another of those as well (4th Axis would have needed it anyway I expect).

I did a bit of tinkering over the weekend and one of the x axis ballscrews was out of alignment, so have also rectified that whilst waiting for parts.

More as I work on it.....

Erm . . well 6A is low for 4 drives and personally I would.!! . . . But worth trying first and will probably only cause you problems if pushing hard.

Being honest with you and Gary probably won't thank me for this.! . . Instead of buying another then I'd build one to suit your requirements exactly. It will be cheaper, take just the same room in control box has the one you have now. If you need the 5V then buy a cheap linear supply for £5.
If you then sell the existing 806-5 it will end up costing you next to nothing.!!

LOL would you believe it, just as I think "yep, I'll go with the dual motor setup on the X-Axis" Sod's law kicks in and the PM752's are not easily available (ebay from China only), but there are comparable digital drivers available and my guess is I'll have to switch out the Z Axis driver to be the 2nd X Axis and run the new driver in its place. That's assuming MACH3 has no problem with a mix of drivers (provided they are tuned to the same steps per rev etc.?)

Mach doesn't know or care what drives you use it just sends pulses to the drives based on your preferences in motor tuning.
You'll see a difference between digital and Analogue drives but it will be positive not negative and the smoother Digital drive will work good on Z axis anyway.!
