Does anyone know of a source of 3/8" helical acme to stepper couplers? I am having trouble finding them. https://reprap.org/forum/read.php?1,235521,235521#msg-235521 Wed, 07 Oct 2026 20:45:28 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?1,235521,235844#msg-235844 https://reprap.org/forum/read.php?1,235521,235844#msg-235844
I found these [www.ebay.com] but I think that the 1/4" is going to be slightly to big to tighten down.]]> jzatopa General Wed, 14 Aug 2013 18:20:46 -0400 https://reprap.org/forum/read.php?1,235521,235814#msg-235814 https://reprap.org/forum/read.php?1,235521,235814#msg-235814 akhlut General Wed, 14 Aug 2013 16:35:06 -0400 https://reprap.org/forum/read.php?1,235521,235808#msg-235808 https://reprap.org/forum/read.php?1,235521,235808#msg-235808 -------------------------------------------------------

My problem exactly, it seems others are using printed couplers or are using a lathe to turn down their acme rod ends. I don't have easy access to a lathe. I am using printed couplers right now but they are giving me terrible z banding as they are solid and give no alignement error compensation.]]> jzatopa General Wed, 14 Aug 2013 15:56:07 -0400 https://reprap.org/forum/read.php?1,235521,235796#msg-235796 https://reprap.org/forum/read.php?1,235521,235796#msg-235796 -------------------------------------------------------
