Oh crumbs. Here we go!

Well I've managed to restructure my Z Axis. I've had to compromise on the travel to space out the linear bearings a bit more. But hopefully it should now be a bit more rigid. I've also swapped the bearings onto the stationary back plate and moved the rails onto the moving part. I've also been able to shave about 20mm off the width too. It's now approx 160mm wide by 330mm high with 150mm of travel. I don't really want to go less than 150mm of travel. I suppose the I could always add longer rails at a later stage if I ever really need that extra travel, and could also then move the bearings even further apart. Lesson number one learnt, design the bloody thing before you order the parts!

Now to start looking at connecting it to the Y axis. Thanks all for clearing that one up.
