How about a mycncuk cnc router project?

LOL, when I first started searching build logs, I tried to find his log too because when he helps so many with designs errors, you would think his machine will be the almighty. but as you read on about him helping using his machine as examples, you get a mental image of this ali cutting beast, with a stair lift beam gantry, steel box section frame, large motors with pulleys and long belts , interchangeable mdf, ply and ali beds, oh and 5mm pitch screws. Sounds like a strong machine with an unconventional gantry. Put our imaginations to rest. Pics please.

NO NO NO NO you don't want to see my beast it's certainly a case of "Do Has I say not what I Did" and it's rough ready engineering at it's best. To be honest it's on it's last legs and in need of some TLC which it will get this year and possibly get turned into a plasma cutter.?

Here's a pic of my son in early days doing his "I'm a little tea pot" routine. .

Yep thats one of THE most important ingredient Geoff.?? . . . It keeps the fire going.!

Seriously now.!! An amusing now but scary then thing happened with that MDF.? It was used for the bed initially and the first Job was the obligatory Mach3 Road runner drawn with a pencil held in 1" square off-cut of Ali with hole drilled in end and pencil jammed in. It performed flawlessly and after many other doodles I was satisfied and set about some fine tuning and checking of the motors with dial indicator.
So while using the MDI (manual data input) I told the Z axis to go down 10mm.!! . . So I thought.?? Nope some how an extra zero slipped in and off it went on it's way 100mm down.!!! . . . . In the blink of an eye it punched a perfect 1" Sq thru 2 x 18mm mdf sheets and the Z axis didn't flinch just did has it was told. .

The computor will always do as it is told (unlike the wife!) the trick is to tell the right thing. Impressive tho isn't it. G
