Thin sheet question Hello All I am currently constructing my thin sheets and have a few questions.... 1) I am using the aluminium from a cider can. This seems awfully flimsy. Has anyone had to change their thin sheet to some stiffer form of tin or am I overly concerned? 2) The template given by the dfx file accessed from here gives a different shape for the x-flag given in this jpg. Can anyone please clarify? Please see the attached shot of the template printed from the dfx file here. [attachment 2432 thinsheetdfxtemplate.jpg] Thanks people. https://reprap.org/forum/read.php?151,48731,48731#msg-48731 Mon, 05 Oct 2026 13:13:40 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?151,48731,54095#msg-54095 Re: Thin sheet question https://reprap.org/forum/read.php?151,48731,54095#msg-54095 jkeegan General Mendel Topics Thu, 05 Aug 2010 07:50:06 -0400 https://reprap.org/forum/read.php?151,48731,53137#msg-53137 Re: Thin sheet question https://reprap.org/forum/read.php?151,48731,53137#msg-53137
Just buy a pair of tin snips at the hardware store, grab a can of soup or something, and cut them according to your paper cutouts.. Bend the folds with a pair of pliers, and you're good to go. Aluminum cans are a waste of time (at least without folding them, as davmj did, which I didn't try).]]> jkeegan General Mendel Topics Tue, 27 Jul 2010 16:52:29 -0400 https://reprap.org/forum/read.php?151,48731,53094#msg-53094 Re: Thin sheet question https://reprap.org/forum/read.php?151,48731,53094#msg-53094

Another thin sheet problem I had was that the Y flag screw hole was in the wrong place, so the Y flag comes in at an angle and doesn't even reach the opto endstop.

How can the Y flag screw hole be in the wrong place, it is a simple rectangle?

If your Y flag is not matching up to the opto coupler on the Y motor bracket then you have either mounted it wrong (unlikely), or you don't have the Y motor bracket mounted in the proper position relative to the Y bars (more likely).]]> rhmorrison General Mendel Topics Sat, 12 Jun 2010 07:52:38 -0400 https://reprap.org/forum/read.php?151,48731,48793#msg-48793 Re: Thin sheet question https://reprap.org/forum/read.php?151,48731,48793#msg-48793
on the ball as ever :) That explains it clearly. Thanks]]> AgeingHippy General Mendel Topics Sat, 12 Jun 2010 05:57:21 -0400 https://reprap.org/forum/read.php?151,48731,48787#msg-48787 Re: Thin sheet question https://reprap.org/forum/read.php?151,48731,48787#msg-48787

Minor change to X opto flag to give it two mounting holes (prevents rotation).

That commit changed the .dxf file, but not any derived files such as .jpg]]> jmarsden General Mendel Topics Sat, 12 Jun 2010 00:26:54 -0400 https://reprap.org/forum/read.php?151,48731,48782#msg-48782 Re: Thin sheet question https://reprap.org/forum/read.php?151,48731,48782#msg-48782

I am concerned about the stiffness and having to replace it later will be a bit of an irritation...

well... gotta go visiting now although truth be told, I would rather continue building my printer :)]]> AgeingHippy General Mendel Topics Fri, 11 Jun 2010 15:03:15 -0400 https://reprap.org/forum/read.php?151,48731,48745#msg-48745 Re: Thin sheet question https://reprap.org/forum/read.php?151,48731,48745#msg-48745
Either one should work. It looks like the dxf one just has an extra mounting point so it won't twist arround on the bolt. I'm using the single (jpg) one and it works just fine.]]> Azdle General Mendel Topics Fri, 11 Jun 2010 14:43:13 -0400 https://reprap.org/forum/read.php?151,48731,48731#msg-48731 Thin sheet question https://reprap.org/forum/read.php?151,48731,48731#msg-48731
