Nasty displacement - solved

[gr5 2,172]

It's not skipped steps. If it were skipped steps the affect would continue upwards (it wouldn't recover).

No I think the problem is that the friction on the long belt pulleys is so high that when the stepper comes to a stop, there is still a lot of tension on the short belt trying to move the head but the head doesn't move the last .5mm or so.

It never occurred to me that you can get play/backlash if the belts are too loose or too tight but now I know.

Heh Cool that you and everyone on this forum fixed it!

Now print sumthin Beautiful!

Nah just kidding,

Actually I feel this is a case of:

If something is complex and difficult, it is solved fast,

If something is obvious but also easily overlooked, it takes many minds a long time.

(we dutch have a saying on this, but the translation to english are never good. Like :One must not pick old cows from the waterstream)

Cheers, and good luck printing!
