    First router/mill build, I've built two tables before but they were for Plasma cutting, this time I wanted something that can cut wood, plastics, aluminium etc.

    I thought up some ideas but after asking on here, they were dumped for tried and tested designs to save risk of wasting cash, basic ideas were courtesy of JazzCnc - thanks for the kick-start

    Practically all-aluminium structure, 3NM stepper motors, digital drives, 1610 ballscrews, 20mm HiWin motion, Mach3 control via a UC100 motion controller. Y axis is twin screw with single motor and belt drive via 15mm HTD belt, X axis is single screw/single motor again with 15mm HTD belt. Currently ALL pulleys are 20t 1:1 ratio but being belt/pulley drive will mean I can easily adjust ratios later depending results.

    I had a large lump of cast iron 410x600x18mm which was machined on both faces - this is to be the main bed of the CNC, I will use a sit-on bed of 12-15mm machined aluminium for metal work and an MDF bed for wood and plastics.

    On order from Aliexpress I have the ballscrews, motion, support bearings and a 2.2kw water cooled spindle and VFD. Intent is to control the VFD/spindle speed via the 0-10v BOB I have got, also got a dual relay board for the water pump, coolant etc.

    Most of the aluminium has arrived, it's all 20mm and 15mm machined tooling plate, surface finish and dimension is perfect. The structural beams are 45x90mm heavy-duty section.

    First cuts were made today, started on the gantry support arms...

    Might not look much but thats two heavy slabs of 20mm ally, my idea is to build and get it running then remove the supports and mill them to the customary inverted L shapes and radius the corners for safety.

    Fun times ahead but having built two CNC's before, this one should hold few surprises I feel
