I'm still trying to finish my build and was about to start the wiring and noticed that the drive gear for the extruder has considerable slop. I believe it is a wades extruder design that came with my prusa 2 kit. The extruder shaft is held to the drive gear with some nuts and those nuts are supposed to fit tightly in and indentation so the shaft always turns when the gear turns. But the nuts are not a tight fit and there is probably a 25 degree rotation of the gear without the shaft anytime the gear changes direction. Is the gear printed wrong or do I have the wrong nuts somehow? Is there some common way to fix this slop?

I'll see if I can take it apart and epoxy a nut in place. I think that would fix the slop if the epoxy will really hold.

I do plan to print a whole new set of parts once I get it up and running, but for now I need to make these parts work.

Let me know if anyone has any other tips. Thanks!]]> cobrageek General Wed, 18 Sep 2013 10:05:15 -0400 https://reprap.org/forum/read.php?1,246274,246303#msg-246303 https://reprap.org/forum/read.php?1,246274,246303#msg-246303
You might be able to print even with severe slop, if you disable retract.]]> Nudel General Wed, 18 Sep 2013 03:40:34 -0400 https://reprap.org/forum/read.php?1,246274,246295#msg-246295 https://reprap.org/forum/read.php?1,246274,246295#msg-246295 /Andreas]]> anwe79 General Wed, 18 Sep 2013 02:48:35 -0400 https://reprap.org/forum/read.php?1,246274,246274#msg-246274 https://reprap.org/forum/read.php?1,246274,246274#msg-246274
