The Z stepper could still move when I rested the new spindle ontop of the old one so I thought there was a good chance of being ok. IIRC I'm running the steppers at 1.5A/19V.<br /><br />I just chose a place to cut the original mount. Then started sanding to get it a little more true. There is a video floating around of a guy using a mill to do it right, which would be the better way if you have access to those tools. I just got things reasonably close for a first plate. Looking at the 1mm Z steps that are cut with the mount I think the spindle is not too far from square.<br /><br />For me, sanding and level gauges were the method to get it reasonably square. No doubt it is not fully square as would be able to be done on a mill, but it seems to work.<br /><br />I noticed the one shot too, it seems there are not places selling additional mounts. Otherwise I would have bought a second mount and worked on that so I had the first to revert to if things didn't go well.<br /><br />I did have to calibrate the x,y,z steps/mm a little after the mod. Though the amount is in the less than 1% so it might be that I didn't make large enough things with close enough fits before to notice the slight calibration issue.<br /><br />The Z stepper structure seems to be holding up so far. Though I might replace part of that soon to give more Z travel than the default.<br /><br />monkeyiqhttps://www.blogger.com/profile/12382939905283275637noreply@blogger.comtag:blogger.com,1999:blog-3005450802120168081.post-49754667074825257262017-01-02T13:21:57.484-08:002017-01-02T13:21:57.484-08:00Looks really interesting!
