Luke11CNC Build Log ,I'm so naïve

[luke11cnc]

Jazz I don't mind recapping:heehee::heehee:

This is the second recap I've done but lost the first one I typed 10 minuets ago


You are Correct the bed is not finish yet three more length of extrusion to add 45x45 profile. the gantry is moved by two ball screws, two stepper motors and two drivers.

ball screw are to be mounted to the under side of CNC rail show in this photo



Material I would like to cut is Aluminium, oak, maple, MDF and Acrylic

I am building this with the idea of adding a 4th axis for turning wood

Ok the drawings well most of it is in my head and as I'm new to most of the drawing software I'm finding it hard to articulate my self but here is a drawing of the Y-axis



the Gantry sides and supported rails are shown in blue

profiles are as follows
gantry side 45x180 extrusion

gantry rail supports are 45x45 extrusion with a bolted brace in 12 mm Aluminium shown in yellow witch will also be bolted to the gantry side rails to stop twisting and vibration movement

shown in green is the Z-Axis support made in 20x 200mm I have gone for a box configuration as it is a lot stronger than a lot of the open three sided I have seen

the rails are 20mm supported and I may even change the drawing to include a third rail at the back in line with the ball screw attached to the bracing aluminium

the gantry sides will be attached to the angle bolted to the support bearings by no less than six bolts


I do hope this makes sense to you :whistling::whistling:
