Hi All, been reading and learning a lot on this site for quite a while, I built an mdf cnc last year and like most people got hooked and needed to build a better one. I decided to go with a fixed gantry this time and it looks like it will be a lot more stable than my previous moving gantry model. slightly larger footprint is small price to pay.
I used 1"x3" coated mdf for this one ,I have used the 3.1Nm Nema23 439oz stepper motors and TB6560 Driver board from 1st machine.
I would like to thank all the people on this site for the helpfull information I have gained.
Cheers, Tony.

Hi Jonathan, I used TR16x4Dx1500mm and 1000mmTrapezoidal Acme Leadscrew for the X and Y axis and 10 allthread for Z axis. had a couple of teething problems this last 2 days but will be all sorted out tomorrow.
Got a new 25cc 2 stroke strimmer engine off ebay the other week so thinking large scale ( 8 foot wingspan plane ) using 1.5mm ply, got a lot of plans to play with, ( probably won't get off the ground but it's something to do
).
Tony.

Tony sounds like fun, built a 1/4 scale CAP29 back in the late 80's with an old strimmer engine and wished i had the cnc then. It was all made out of light ply and i had to turn down the fly wheel on the engine to make it lighter and insert a four bolt concoction to mount the prop....Have fun
If the nagging gets really bad......Get a bigger shed:naughty:
