Advice please on 100cmx60cm CNC router

[bigal999]

Thank you again for your answers I agree I may have been a bit too fast to buy some of the parts but am stopping now till I have built my frame.
I am having doubts about my frames design at the moment so if you could please answer these questions.
1. X axis will be 40x80 profile 100cm X 60cm. Will I need a center brace at the 50cm point or not. I was planing to brace all the corners with 10mm plate.
2. Y axis will be running in 20mm supported rails.
Would 40x 80 be ok for the side legs to hold up the carriage.
The carriage that z axis will be running on will be 2 40x80 profiles with a 50mm gap for the ball screw to run in-between them . Will they be ok if I put a 10mm brace in the centre between the 2 rails. z axis will run on 2 20mm supported rails one mounted on each rail.
Z axis is still in design stage.

Hi Albert,

Well depends on the usage to be fair and with such a vague description of the design, it's not easy to give good or meaningful advise. But again like the components, I suggest you do some research before building or ordering stock and if possible create a Cad model of the machine or at least a detailed drawing. This will help you visualize the machine and potentially catch any gotcha's that nearly always bite you when building the first machine.

I'd also recommend you start a build thread and start asking your questions and show your design ideas. This way you have one source for reference to go back to later as it can take many weeks or months before you actually get to the building phase.
