anyone have a good method of aligning the lead screws for the herculien?
no matter what i do i dont seem to be able to get it right. its always binding somewhere and if i get the bindingsorted in one spot. it binds in another UGH!
So damn frustrating.
i have tried using calipers to check distances and doing it that way.doesnt work.
ive tried just doing it by feel manually. doesnt work.
Have you measured the top and bottom of your vertical extrusions to make sure the spacing is equal? By this, I mean if you are looking at the front of the printer and you measure the from the narrow face of the v slot to the front of your frame it should equal 235mm.
I’ll send you a video later tonight regarding the assembly of the vertical axis supports
Yeah feedrate is important- I set mine to homing=15mm/s but only 3mm/s feed rate. I used ballscrews and didn’t have much problem with Z binding at all- I did have a little due to the two nuts being at different heights- it’s important that the screw nuts are at the same position on both screws- I measured with a caliper the protruding screw height above and below the two ends. I just used a tape measure to make sure that the two Z screws were in the exact middle of the X and Y (horizontally).
@Jim_Stone there is a not insignificant break-in period. I’m both of my printers I’ve been amazed at the difference between what I thoguht was ‘broken in’ and what they felt like after a steady week of operation.
