Ready Steady Eddy

I had to strip it down a bit today because there was still a BK and FK bearing to sort out, both had bearings in facing the same way and no grease, made shims, greased, reassembled.
More progress, ready to order some energy chain and start wiring and I'm very pleased the panel is already built.



Limit and home switch for Z axis, there is one switch and two strikers. For the home switches I mounted a piece of 6mm thick mild steel to aluminium angle to act as the target.



Motor mount for Y axis



limit switch and adjustable striker for Y axis, there's another striker at the other end of the gantry, so one switch with two strikers.

Eddy I would move that bottom switch as the swarf and resin builds up very quick around the bottom of Z axis and you'll be cleaning it constantly.

Noted, however I did have a struggle to find a better position for the switch so that it could be operated at both ends of the Z travel. If it becomes a problem in use I'll move it and remember I'm cutting wood.

Wood is even worse than Aluminium for sap and resin etc, honest you'll be surprised just how much it collects at the bottom of Z axis.
Also with Z axis why would you need a Limit on the down because often the bed is the limit and it just stops. Most Z axis only have limit switch at the top so put it at top.!

There's no sap or resin in any wood I cut but I'll see how it goes once cutting starts.
If there was no down limit the front plate would 1/2 leave one of the hiwin blocks before the ball nut hit the end, also I like the idea of a limit at each end.

Ive been aware of this thread for a while, but tonight, only just read it.

Nice Design!!!. Must say, hats off to you much better than mine. I think every single thing I wished I did with mine you have done here... Proper Rails, I like the extra plate at the top of the Y carriage (making a figure 8) The X steppers inside the gantry (rather than sticking out). and the general quality of the build looks superb

Credit to you chap. Got to start thinking about my next build soon...

Thanks for that, but it was thanks to your initial drawing and design that really took me from floundering to finding a route through it.
