Well Done Bruce,

Coming along well and looking good. Keep it up and it will be running in no time flat.

Just a quick update. Been busy and work is about to kick in. The y gantry is almost finished, probably another 6 hours should see it done. The z is waiting on Michael Marino's machine becoming available and then we can machine the recesses in the plates.
Going to see if i can coax my mate to do the welding of the frame for me. So it is progress just a bit slow. Would be quicker if i made less mistakes!

Next update. Its now a rolling y chassis. The mounting plates above the x bearings will be cut down to size after i know where the ballnut bracket will be located. It does not look much since last time but I must have drilled and tapped 50 or so holes.
If all the limit switches are connected in series would it make sense to mount them all on this gantry as this would mean only one cable going from the gantry to the control box?

Yes With a bit of care and planning it's possible to use just 1 switch for each axis all wired in series. Doing it this way then yes it's possible to mount them all on the gantry.
Basicly you need some kind of ramp or bracket either end of each axis to trip the switches.

Confession time now bruce I forgot to do what I've got to do.!!! . . . Will do it ASAP promise. .

Okay base is on the way and looks more like a jazz base then the previously drawn tea trolley. So I am starting on the electrics. Laid out a few components and will hopefully get some wire, plugs, connectors etc tomorrow.

Fillets and bracing added by the blacksmith.

Looking to get the limit switches now and was wondering if the chinese 10 for a bowl of rice are worth the effort.
I presume that I will need to get some 0.2 2 core shielded cable.

Today it took its first breath of life. The control box is almost complete. I just have to get some 5 pin plugs and sockets for the motors. I decided to make a temporary connection to a motor and try it out. Ya beauty! Worked a treat. Got some good advice from Michael and I am well pleased.

Some more ally arrived yesterday so as soon as possible I can continue the build.

In the photo of the control box the wires hanging out the side are the temp connection to the motor.

Looks like you have made a good job of that control box.
