i had used 20 mm flanged bearing blocks in the original dwg and that impacted on the clearance for the ball screwnut. I had also designed the z axis plate to be machined at 160 mm wide to try and keep the gantry length to the minimum . I should have used 20 mm square type bearing block to give more clearance and accommodate the 160mm width. ya i will stick with the z axis travel of 150mm - 160mm and adjustable bed. good call. i will have to get a supplier organized for the guides and rails. I dealt with chinese suppliers in a previous job and there were reliable so i'll drop them a line and see where it takes me. maybe i should wait until i have secured the rails and guides before I go any further with the z axis design?
