been busy redesigning and rebuilding the z axis.
I reversed the setup. rails are now on the moving zplate. this seems to be a much better setup.

Hi Stef,

Coming along nicely, Good choice changing that Z axis it will perform much better.

Before you start making chips I would cover the gaps down the side.! Amazing how much crap gets onto the screws and nut, it will also fill that cable chain in minutes.

oh yes, i'll make sure a do that.
still a few things to do before cutting anything though. cooling needs a new pump (washing machine pumps are not powerfull enough), i need to attach a few cables, and sort out the cable chain.

Be carefull with the pump.!. . 2 main things to look for are Head height if pumping from a tank and duty cycle time. Duty time is often the thing that kills pumps and you need one that is rated close 100% as possible. . .These spindles don't need large flow just a nice continous one.

I used a fish tank pump with 2mtr head height, it's just died after nearly 3yrs so I'm happy with that. Now I have a 24V 7mtr head height pump bought from Ebay and it's working nicely.

How long would the spindle run without cooling before trouble sets in? Would you go as far as putting a flow switch wired to the estop?
