I am currently using the M4 one. <br /><br />I thought I had bought a 40 tooth gear, but when I bought another I realised it was actually 38. Meccano made both in the same diameter so I would recommend 38 as it has thicker teeth.nopheadhttps://www.blogger.com/profile/12801535866788103677noreply@blogger.comtag:blogger.com,1999:blog-4339813531032979196.post-1301867213498857262010-01-26T18:33:14.751+00:002010-01-26T18:33:14.751+00:00Ooops I miss read the tap size as 3mm just re-read...Ooops I miss read the tap size as 3mm just re-reading your sugestion.. as it fails using 3mm teeth are too fine like sitting on bed of nails is best analagy I can think of..<br /><br />Oh What ratio do you have on your worm drive gear please ?Anonymoushttps://www.blogger.com/profile/11790019375326311849noreply@blogger.comtag:blogger.com,1999:blog-4339813531032979196.post-36767209405950651132010-01-24T13:12:57.597+00:002010-01-24T13:12:57.597+00:00Yes for the bigger part I had to use 55C all the w...Yes for the bigger part I had to use 55C all the way through the build so that is my setting for PLA now.<br /><br />I think 100C for ABS is good enough to get it to stick. I only use 120C if I need an aesthetically good base. 120C all the way through discolours the ABS a bit, but not a problem otherwise I think.<br /><br />Yes you need to cool it below the glass transition before removing it. I am not sure whether it needs to be cooled further but I picked 40C as it is comfortable to touch and below Tg of PLA.nopheadhttps://www.blogger.com/profile/12801535866788103677noreply@blogger.comtag:blogger.com,1999:blog-4339813531032979196.post-60250488548955862682010-01-24T12:22:36.934+00:002010-01-24T12:22:36.934+00:00NopHead, great wrok as always :-)

The outline stuck properly and the base is nice and shiny."<br /><br />Could we print maintaining the same 55ºC for all the layers? (the same question goes for ABS values).<br /><br />I am trying to understand if we could have a simple and manual control system, like configure it just for one value.<br /><br />On my tests, I used about 115ºC for ABS for all layers, and it worked nicely, but I didn't yet much prints... one time I remember to remove the printed piece just after the end and It was very soft! I did deform it... now I leave it colling until ~40ºC.Casainhohttps://www.blogger.com/profile/09458423869238512900noreply@blogger.comtag:blogger.com,1999:blog-4339813531032979196.post-38083776382645643632010-01-23T23:14:52.951+00:002010-01-23T23:14:52.951+00:00Yes I am using the AKA47 "worm" pulley. ...Yes I am using the AKA47 "worm" pulley. It is 15mm OD, ~13mm ID using an M4 tap. If I was making another I would try halving the ID to 6.5mm and use an M3.5x0.6 tap with an OD of 10mm, so yes you could use 1/2" stock.<br /><br />I would also add a boss with a set screw rather than using a splined shaft.nopheadhttps://www.blogger.com/profile/12801535866788103677noreply@blogger.comtag:blogger.com,1999:blog-4339813531032979196.post-11741478551847591422010-01-23T23:02:37.734+00:002010-01-23T23:02:37.734+00:00Thank you for the link to your Table I had forgetn...Thank you for the link to your Table I had forgetn that post it is very usefull.<br /><br />Are you now using the AK47 brass pully method?<br /><br />If so what is the diamiter of the pulley or its final circumferene?<br /><br />Im thinking as Im not struggling for tourqe I should try for the better grip method before I get to the point of not wanting to take something that is working apart.<br /><br />I found a 10" length of 1/2" brass bar left in my shed by the previous home owner. I could use this?Anonymoushttps://www.blogger.com/profile/11790019375326311849noreply@blogger.com
