Hi Poppy ann
Welcome to the forum, i am a novice @ the cnc game but you have unfortunately made the classic mistake of buying equipment without having a working drawing/plan. however the guys on the forum are better equiped than myself to advise if the gear purchased will be suitable. the general rule is first do a lot of research ie read the build logs( i know they are long but the information they contain is priceless) then use Google sketch up to design your machine and offer it to the members for comment.
They will point you in the right direction.
Regards
Mike
