    Hi
    My dad owns his own joinery workshop but wants to be more competitive with price and a CNC in the workshop would do this.
    As his background is in woodworking sidewinder cnc on youtube caught our attention due build materials being made from ply.

    Basically we have his plans and wish to upscale them to cut a 8x4 boards.https://youtu.be/-jujswCDgzQ is the link to his series of videos. Please educate me on the issues that will/might come up with the up scaling of the plan? Is ballscrew the best option when travelling 8x4 board?

    Thank you for any replies

    Hi Toby
    Welcome to the forum, hope you didn't spend a lot of money on your plans.
    Sad truth is wooden routers are not upto it, especially @ the size you are thinking of. If you had browsed the forum you would have found that plenty of people have asked the question and all received the same answer.
    I don't know what sort of precision or repeatability you are looking for but to be honest you are going to have to go with steel frame @ this sort of size machine.
    Regards
    Mike

    Thanks for the fast reply, fortunately the plans are free. We already have a steel box table frame to mount it on.

    Hi Toby,

    if you are professional, buy professional quality machines. The faffing and aggro are not worth it especially if you want to remain competitive.

    MDF is not a good material to make a machine out of. I have recently made parts for a workshop that realised this after spending way too much money on a machine.
    You will probably need to establish how much you want to spend n the machine you buy based on the business you expect to bring in. When you do that, buy the best you want to afford.
    Not looked into the woodworking side of things at all but ultimately, you are better off buying something in your home country, especially if you do not have much CNC experience. Importing a machine may lead to issues that are again, not worth the hassle for the monetary saving if any.

    If you want to build for the fun of it, then by all means do so. It is very satisfying to make a machine that could potentially make its money back. The cheapest linear actuation would probably be if you used rack and pinion as ballscrews at 8x4 lengths tend to be rather expensive. Keep reading on here and other forums to get more ideas.

    The false economy of chinese machines :
    -no support on hardware if anything not working
    -no support on software
    -no support on learning
    -shipping fee????
    -VAT and customs +20 ???%
    -most of these finish with at least the breakout board reaped out and exchanged for a proper one, recommended thing is to do for all electronics
    -not even any forum support

    Just have a look at the forums how many people can not make work their Chinese breakout boards, laser, plasma and cnc machine. What more to say?
