Eddy's suggested settings are a good starting point but must say your going about this all wrong by turning on very flakey drives with no clue how to set them up or what your doing.! Guessing at these things is just asking to let out the magic smoke and these drives are full of smoke just bursting to get out.!

Sorry to say this after the event and probably not what you want to hear but still needs saying IMO.!! . . You have really wasted £108.! Even if they survive your best efforts to kill them the performance you'll get will be rubbish with only 24V and motors with 14mH inductance.

Cut your losses now and sell them before you kill them and buy some decent gear because with machine having dimensions of 900 x 700 you'll want half decent gear on it otherwise you'll be really dissapointed with it when it could probably be so much more.? (depending on build quality)

Trying to do it on the cheap in case you blow things up is completely the wrong way to go about it.! . . . Separate drives are no harder to wire than all-in-one boards and they are far more tolerant and robust than TB based drives and can be cheap if you shop around.
Cheap motors are often very low quality just like those you have with high inductance which plays a major part in the performance you can get out of them. PSU's are cheap enough if you look around Ebay and not at all difficult to build if your that way inclined.

Your much better off waiting and saving for the real thing than wasting money and getting frustrated or turned off CNC by cheap nasty toy town electronics.!!
