TBH if im really honest i dont really know. but i want to build a cnc
Ok but if you are really serious you need to get some proper drawing done but first look through some of the build logs on here to get ideas as the the one you have put up I don't think will even ice a cake. Please don't let this put you off. So decide on a cutting size you want and then half it. To build a decent machine you will need a budget of around £1500 - £2000 using decent drive, motors, screws rails etc. Also the golden rule is don't buy any electronic stuff until you have the frame designed and sorted. Good luck with the build. My first one took me about 10 months from start to making chips and all knowledge was gleaned from this forum.
