Changing to Hiwin design from round supported parts advice grateful.

[grain_r]

Hello

My build has been going slower than i thought and to build my current round rail design and upgrade will take a lifetime so i have Emailed Fred at BST Automation. I thought it would be easiest if I got everything at once to make the freight cost better. but i'm not really sure if i have got everything correct on my parts e.g the correct voltage for the motors and drivers. i haven't asked him for power supplies because i Forgot.

Would you say its better to do it this way or buy the parts as and when. It would make my simple brain think the build was a better price to fool me and make the nearly truths more believable to my wife.

I would be very grateful if you could look to see if i'm on the right road, Last time I went ahead with the sbr20 without asking ans regretted it. the machine isnt really designed for any particular use and so an all rounder is hoped for and hopefully make a little back in time on small jobs

Thanks
