Hi Gobo

once you have read a few posts on here you will appreciate how many times the same thing gets asked....

My first machine was made out of mdf, Drawer runners for linear motion; a dremmel for cutting and old printer stepper motors for drive...

There are many many videos on the web of people who have made wooden machines; thing is, most of these people end up starting again once they realise the draw backs to making machine out of these materials.

in answer to your question. Yes; it can be made out of MDF; dont let anybody tell you otherwise. but it does very much depend on what you are cutting out; how often the machine is going to be used; where is it going to be stored (MDF cant be kept in a damp garage)

If you are making a machine; as a proof of concept in a warm bedroom for cutting small signs; then I would encourage you to try... because you will learn so much along the way and id always encourage people to get into the hobby. if your anything like me, you'll learn a hole lot along the way.

Only thing I would say (before everybody jumps in) I would encourage to get the electronics right from the start even if you cant afford "proper" materials right now. DO NOT BUY anything before reading up on here first.

the TB650 driver on ebay is a classic example.
