i dont deny that for one minute and i'm not saying it's a bad thing either at the end of the day you make the machine, it works, you forget to take pictures, you then get busy and spend more time designing parts to cut on your cnc and either dont have the time or forget that you didnt finish the build log.. i have to say i'm guilty of this from when i started making homebrew and for that reason i want to stick around here after my machine is finished and try to help people not make the same everyday mistakes, but also to showcase my build as best as possible to give hope to people that it can be done.
one thing i've never found though jazz is your build log

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.?

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. .
