Topic: SD2 Y axis clunk

Finally got it adjusted where I thought it would print - it did, for a few small prints.  Tried to print the flat brackets for the MK1 spool holder off Thingiverse.  It seems that any long y-axis travel causes a noticeable 'clunk' when changing direction into the y-axis from back to front (+ to -),  thus causing a 1/16 or so inch rearward displacement of the print on each run .  This happens immediately on the first few layers. 

Finally got most of the 'not sticking' problem solved and now this.  This happens on anything longer than about a 1 inch y-axis print line. 

Really need a spool holder to feed vertically (least resistance), as it seems the spool that came with the filament I have causes too much drag on the print head, and again causes print distortion.

Any help here would be greatly appreciated.  Will reply to any responses Fri evening or so - 0500 comes early for us older folks.......

Thanx

Re: SD2 Y axis clunk

Check to see that your Y belt tension is even throughout the whole belt.  It sounds like some slack is accumulating during the longer excursions.

Re: SD2 Y axis clunk

Thanx for the response.  I found the Y belt calibration/adjustment, and am working on it as we speak.  They show how to adjust it, but they don't show to what tension, or how to know if it is right.   Just gotta keep working at it til I get it right..

Thanx again
