1000*1200 build log.

[m.i.k.e]

Hi Andy and Dean,

Thanks for the kind words and great suggestions.

As for the closed-loop steppers - I realize they are the way to go but I am trying to keep the costs down, They seem to be a decent price for 36v-48v but any higher and they shot up in price. I will have another look and do the maths.

The lack of Y support brace - Yes this is a suck it and see, I deliberately made the frame from 90*5 to compensate for this. I think it would take all the fun out of building my own machine if I just copied yours and other members machines lol, If it doesn't work out I can always add Y bracing later.

As for leveling the Y-axis surfaces - I think I will just use shims because of the uncertainty above ( could also level with epoxy at a later date)

Gantry side plate adjustment - That makes so much sense, I will re-design that.

Check your holes - Yes I think I was guilty of that in my first design a couple of years ago ha-ha.

Thanks for all the input - cheers mike.

Wheels are round because they work best which is why everyone copies them, no shame in copying if it's what works best.!! Adding at a later date never works out well or like you expect and is certainly not fun when it affects sensitive surfaces which are important to machine accuracy.

Also, why 90x90.? That is an odd size for steel which I think you will probably find more expensive than 100x100 as it's less common.!

Last it's false economy buying steppers or drives because they are cheap because you'll only end up eventually buying them again and before that time comes you'll probably pull your hair out chasing issues or spending more money because the machine doesn't perform like expected so buy other things to try and make it better when all along it was the drives or steppers holding it back.
Better to wait a few weeks longer to finish it and do it right the first time, you'll have a far better machine with less stress for the sake of an extra £100 or less.
