As suggested in another thread, here is a starter thread showing a collection of finished DIY router builds from members of this forum. If Lee is OK with this (could it be a sticky?), my suggestions for rules are:

Pictures / video of the finished machine only (no build progress)
Specification of the machine
Hyperlink to your build log (if there was one)
Materials you machine with it
Maybe some comments on how it runs, what you might change next time etc.


No follow-on comment replies or the usual thread discussion, just the single post. Here is mine to kick things off. Feel free to add yours after it . . .

Footprint approx: 1200x700mm
Cutting area approx: 800x500mm
Z travel approx: 150mm
Linear movement: X=16mm supported rail, Y=Hiwin 20 square, Z=Hiwin 15 square
Transmission: 1:1 ball screws 1605
Motors: X,Y,A = Nema23 3Nm at 72V (DIY linear PSU), Z = Nema23 1.8Nm at 72V, all DQ860MA analogue drives
Breakout board: DB25 (Free simple board which came with the drives - OK so far . . .)
Spindle: 1.5 kW watercooled spindle with Huanyang vfd/inverter
Frame- 80x80 heavy gauge aluminium profile, bolted
Gantry- 80x80 heavy gauge aluminium profile, bolted, plus aluminium box section sides, bolted

Build log: http://www.mycncuk.com/threads/6988-routercnc_MK3
Machines: liteply, wood, and occasional aluminium

Notes:
1. Works very well for intended purpose (wood mostly).

2. Would go with 1610 ballscrews on X and Y next time, most likely digital drives, plus at least 2.2 kW spindle to allow tools up to 12mm.

Let me be first then :devilish:. Tried to be short but will give some more details so its easier for people to see the main points. I think video is better than pictures if possible.


The Yellow Machine


https://www.youtube.com/watch?v=C9hTLN1CydU

Footprint approx :1300x600
Cutting area: 1000x400
Z travel 180mm
Linear movement: Hiwin 20 square supported rails
Transmission: 1:1 ball screws 1610, 1605 on Z
Motors: nema 23 3nm at 70V, AM822 drives
Overhang -tool tip center to gantry/rail distance 133/165mm
max rapid speed 10000 mm/min
max working speed 5000 mm/min
acceleration 800mm/s2
frame- 100x100x3mm steel, welded
gantry- 100x100x3mm steel, welded
gantry weight: ~60 kg
total weight: ~200kg
parts price: ~3200euro

Build log (http://www.mycncuk.com/threads/6457-Sturdy-and-Fast-all-Steel-CNC-my-first-build/page9)
Machines: 3d models, fiberglass, plastics, aluminum

Notes:
1.Meant to machine long toolpaths and very fine detailed yacht models, hence the small 0.8kw spindle, which still permits a nice deep cut in aluminum using 6mm cutters. Frame is overkill for wood, meant for aluminum machining. Could handle up to 7kw spindle

2.Free plans in Sketchup A Sturdy Steel Framed Machine Design (http://www.mycncuk.com/threads/6979-A-Sturdy-Steel-Framed-Machine-Design)
Fully scalable to 3000x1250x200 with minor changes to accommodate for bigger size ball screw and eventually rotating nuts. Keep all other distances and profile sizes. Most parts could be laser or plasma cut




The Violet machine

/will make a better video showing all the machine and remove that/

Footprint approx :3300x1800
Cutting area: 3000x1300
Z travel 200mm
Linear movement: Hiwin 20 square supported rails
Transmission: 3:2 ball screws, X 1610, 1605 on Z, 2510 with rotating ball nuts on Y
Motors: Samsung AC 230V servo 400w on all axis
Overhang -tool tip center to gantry/rail distance 110/120mm
max rapid speed 20000mm/min
max working speed 15000/min
acceleration 3000mm/s2
frame- 100x100x4mm steel, welded,
gantry- 100x100x3mm steel, welded, 10mm plate reinforced
gantry weight: ~180 kg
total weight: ~800kg with bed
parts price: ~7000-8000euro /3000euros linear movement, 1000euro frame, 1500euros second hand servos, etc./

Build log (http://www.mycncuk.com/threads/6619-Quite-an-Unusual-one)

Notes:
1. Meant to machine all day long aluminum, wood, including occasionally mild steel. Extremely low overhang.
2. Almost floor stander, 1 person could easily load heavy materials on table.
3. Extremely low weight to strength ratio. typical similarly strong machine weight >2.5 tons. Could handle up to 15kw spindle easily
