1250 x 1250 cnc router (from scratch)

[PAULRO]

Hi Daniel, great build. i have steel ordered for a similar build and am curious to know the inside dimensions of your m/c. the travel of your x and y axis. i have allowed 1440 mm inside dimensions allowed for 1220 mm standard width of sheet.



i'm trying to minimize this dim so i can minimize the length of the gantry. i'm also curious about the distance from the spindle router collet face to the work table . as i say the steel is due in next Tuesday / Wednesday and i'll start cutting the frame members early next weekend so i have these last couple of days to refine and tweek the frame design. any input would be greatly appreciated. by the way ,it would be great to see videos of the m/c in action. !! cheers , Paulro.

Thanks Paulro,
X & Y both have 1250mm travel so will cut a full 4x4 sheet allowing 15mm a side. Just make sure that you allow for the width of the z axis, so that when the z is at either extreme of its travel it passes the board to make full use of the sheet and allow a little extra so that the z axis doesnt max out on its travel.
i think i left 150mm between the collet and top of the bed, i should have made the bed height adjustable really, but maybe next time....
i will try and get some vids up soon, i have been tweaking it lately and trial cutting projects so once it is all ok i will post some videos. let me know if you need any more info, all the best!
