I think I have cracked it what is your views on this drawing




Extrusion 50x50 mm but the down side is they only do it in light

I think your latest design, but mirrored so that the Z-axis is mounted on to the same plate as the ballnut will be strongest:



That way the spindle is closest to the Y-axis ballnut which should reduce flex parallel to the Y axis.

[luke11cnc]

It should be the other way around I don't how how that happened ???

Thank you Jonathan

Oops just realized you mirrored it all ready

James what thickness you using on the plates for Z?

It's 3/4" - same as gantry sides.

Ok my stepper motor covers have arrived but

the stepper motor has 8 wires and the plug for the cover only has 6 pins

are all the wires require ??

do I need to buy new plugs for the stepper motors

James

do I need to buy new plugs for the stepper motors

James

Nah you only need 4 pins wires are joined in pairs so only 4 needed.

[Jonathan]

The reason they put 6 pins in probably in case you're using a unipolar stepper driver as that requires six wires.

Which covers did you get out of interest?

It is as I feared, you bought the ones that 'will not fit the SY60 motor'. The motors you have are actually slightly bigger than Nema 23, so Nema24 ish...23 mean 2.3 inches, 34 means 3.4 inches etc...

Maybe they can be modified. At least it looks like you only bought 2 not 4.
