I'd like the fact that I can sample the first couple of those for free.<BR/><BR/>Okay. Be sure to post the STLs somewhere.<BR/><BR/>Oh, and I want to remind you that you're doing awsome work! :)Erik de Bruijnhttps://www.blogger.com/profile/09433438819279256757noreply@blogger.comtag:blogger.com,1999:blog-4339813531032979196.post-15513045815064448062008-08-06T21:44:00.000+01:002008-08-06T21:44:00.000+01:00Hi Erik, The only thing I can think of electronics...Hi Erik,<BR/> The only thing I can think of electronics wise that would reduce quality is if the CPU is not powerful enough to avoid pauses. The tiny MSP430 I use for my extruder controller is more powerful than an arduino.<BR/><BR/>Yes I will do something similar on the z-axis but I want the tab to enter the side of the opto. I might add a second opto, wired in parallel, looking at a radial tab on the shaft.<BR/><BR/>I dipped the tabs in black BBQ paint. I assume it is opaque to IR, but I have not tested it yet.<BR/><BR/>The pulley you found is the same part number, it is just that the picture does not match the object. It is good job as it would have been harder to mount the pictured one in the lathe.nopheadhttps://www.blogger.com/profile/12801535866788103677noreply@blogger.comtag:blogger.com,1999:blog-4339813531032979196.post-7603244864196046032008-08-06T18:42:00.000+01:002008-08-06T18:42:00.000+01:00I got my ones from RS - look the same (in real lif...I got my ones from RS - look the same (in real life - the RS catalogue photo isnt quite what I got)<BR/>part 744-508<BR/>Slightly cheaper in quantity >6<BR/>I also had to drill them out & drill the grubscrew holes. I did them in one two hits, using my pillar drill & vice. the vice has V notches in its faces to help keep everything aligned. THere is a slight runout on some, but I am happy with the result.<BR/>I used M4 grubscrews cos eeny weeny taps are easy broken.<BR/><BR/>My pillar drill cost 36 quid (or thereabouts) from machine mart. The table isnt flat and much of its cheapness shows, but it works and is remarkably useful.Lampbushttps://www.blogger.com/profile/17019954684509050312noreply@blogger.comtag:blogger.com,1999:blog-4339813531032979196.post-29668918858674806082008-08-06T10:04:00.000+01:002008-08-06T10:04:00.000+01:00Really wonderful that you can do these comparisons...Really wonderful that you can do these comparisons to find out what makes your results so nice. I wonder what difference your electronics will make compared to the Generation 2 RepRap electronics. Hopefully it is not that which makes your print quality so good, but something that's replaced easier (would become my seconds electronics change before having any real results to speak of).<BR/><BR/><B>About the Z axis:</B><BR/>I've made a practical Z-axis end-stop which works with the ordinary printable PCB holder bracket. This is of course a perfect Z-home if you invert the home position (which I think is a good idea).<BR/><BR/>See the first two pictures in my blog here: <A HREF="http://blog.erikdebruijn.nl/index.php?/archives/44-Partial-replication.-First-functional-parts-printed!.html" REL="nofollow">3D printed parts</A><BR/><BR/>You need to superglue a BLACK tie rib to it, or use a marker to make it black (I see you're already doing that). Ordinary white (vinyl?) tie ribs are way to translucent to infrared.<BR/><BR/>B.t.w. what's the farnell id for the pulley. In the dutch shop I could only find <A HREF="http://nl.farnell.com/7092581/industrial-controls-automation/product.us0?sku=synchroflex-ls16t2-5-16-2" REL="nofollow">this</A>.<BR/><BR/><B>-- Erik <A HREF="http://blog.erikdebruijn.nl/index.php?/categories/7-RepRap" REL="nofollow">My RepRap Blog</A></B>Erik de Bruijnhttps://www.blogger.com/profile/09433438819279256757noreply@blogger.comtag:blogger.com,1999:blog-4339813531032979196.post-32374515493498535782008-08-06T01:18:00.000+01:002008-08-06T01:18:00.000+01:00Congratulations, Nophead! :) Another RepRap is b...Congratulations, Nophead! :) Another RepRap is born.Andy D.https://www.blogger.com/profile/16618445790245626648noreply@blogger.com
