    Just responded you to the PM, but now i see here where you are going with that. There is absolutely NO NEED for the spindle to extend below the table bed in order to achieve good 4rth axis

    Meaning that the centerline of the round object could be level on with your bed. And the Z gantry clearance will be your object max radius. Add 10cm for the bit and chuck. There should be your spindle in upmost position. i recommend boxing the spindle like on mine machine and making tha gantry a bit wider in vertical. So more or less a normal machine without too much mods except for strong Z. thats it

    I recall a build by KingCreaky that had a removeable bed that allowed a 4th axis to bolt in (can't find the thread though).

    been over thinking again lol but that's the fun of reading tons of posts on this forum and coming up with new idea's (stolen idea's). just out of interest whats the price difference between good stepper motors and servo motors now? because of my high z axis i need to make the gantry very beefy but after reading some more for 3d work the z front plate needs to be light so i will update soon on an updated version and see what you think.

    What i think for sure is this:
    Do not buy anything more until you have definitely finished your drawing and have it all clear 100%. That includes rails, screws, motors, board, etc. It will be just throwing money in the bin. And yes, we have done it all.

    One more thing to note: Everyone here thinks he is a top machine designer. Nothing wrong with that. And in reality here we could see most of the best build ever worldwide. But what i learned from experience is that even if you overthink your machine, you always mess something, even small. Once you make the machine though, use the machine 1 year 8h per day, maybe make another one later, revise a couple of times the design customising it for clients, then this machine becomes better and better.
    What i am saying is: assume you will make errors, if someone has made a nice working machine and you like the design, ask, listen and copy shamesly. Do not over think and over invent. look for good working designs, easy to make at home.

    Thanks boyan, i have not ordered anything apart from the steel for the frame and while spending the whole of january welding it together i will wait until that is completed before confirming other parts to order. i have seen loads of build logs on here from people who have rushed in and bought the parts before asking and i will not be making that mistake. i am not expecting this machine to turn out how it looks in cad software or in my head but what i am expecting is knowledge from trial and error. that is the way i always like to learn because if you can fix an error then thats a new skill you get to keep :)
