I'm looking into jumping into the 3D printing world and slowly settling on the Up! Mini (I really like the look of their software and ease, but I'm not sure if the far more expensive Up! Plus like you've got is worth the increase in price to me).<br /><br />But... I was hoping maybe buying from someone a little more local could result in a bit of a shipping savings. I'm not having much luck, though. Does anyone know of a US source, or will I have to order from China to get one?Tankhttps://www.blogger.com/profile/11104177751807466668noreply@blogger.comtag:blogger.com,1999:blog-23681518.post-89476845935361019862012-07-04T08:56:16.714-07:002012-07-04T08:56:16.714-07:00Wonderful!

Basically the nozzle tip has to be at more or less uniform distance from all corners/center of the platform. This was done by adjusting the screws used for fixing the platform (very minor fine adjustment) Thanks to 3D printer Malaysia! After this calibration was done. Now its working fine!Darshanhttps://www.blogger.com/profile/02129050939614819963noreply@blogger.comtag:blogger.com,1999:blog-23681518.post-33956718162719885192012-07-02T14:20:11.675-07:002012-07-02T14:20:11.675-07:00I mostly print small, fine detailed objects on the...I mostly print small, fine detailed objects on the UP!

I had a heater line die in the ribbon cable which meant the drive gear stripped out trying to drive into a head that was too cold. The printer errors on 'head too cold' but obviously not fast enough to stop it stripping out. The fault was at the IDC connector at the extruder end so I cut back the cable and replaced it as a quick fix while pp3dp sent a new ribbon cable free of charge.<br /><br />I think disassembling the extruder is actually part of the recommended maintenance in the manual?<br /><br />Forrest: You say don't print big monolithic objects? You mean solid or just large? I've successfully printed quite chunky objects that needed to be structurally sound at the full bed size (130x130 although only up to about 100 high). I'm 100% convinced that having the printer inside a cardboard box at ~40-50 degrees is what allows this, although the acrylic spray can bed paint as well as having the bed level, a long pre-heat and a very 'squished' first raft layer helps.Anonymoushttps://www.blogger.com/profile/07904513732374823957noreply@blogger.comtag:blogger.com,1999:blog-23681518.post-54588501170413104082012-07-02T05:56:39.634-07:002012-07-02T05:56:39.634-07:00There is no need for that.

When a support platform for a raised, curved surface is printed the support surface looks a bit knobbly. I'm not sure how they achieve that effect.<br /><br />It is as you say in the second case, though, contact between the support cradle and the print object tends to be sporadic and tangential.<br /><br />This technique isn't perfect by any means. I've noticed that it tends to work best with large, gently curved surfaces. Smaller, more tightly curved surfaces don't print all that brilliantly. They print well, mind, just not brilliantly.Forrest Higgshttps://www.blogger.com/profile/17208965471464716174noreply@blogger.comtag:blogger.com,1999:blog-23681518.post-84119457651240395502012-06-19T12:18:22.625-07:002012-06-19T12:18:22.625-07:00What I meant was is the filament on the bottom lay...What I meant was is the filament on the bottom layer not pressed flat like a Reprapped object but still largely cylindrical.

And it as the normal layer height. I think that makes the layer extruded onto it sag between the gaps in the support so it forms a weaker bond to the layer above but bonds quite strongly to the support.nopheadhttps://www.blogger.com/profile/12801535866788103677noreply@blogger.comtag:blogger.com,1999:blog-23681518.post-85221578178934536492012-06-19T06:18:30.941-07:002012-06-19T06:18:30.941-07:00Hi Erik!

That sounds horrible! I haven't noticed either the frame or the thermocouple problem you're talking about. I am wondering if these problems have been addressed in current production? How long ago were the printers you are talking about acquired?<br /><br />"I guess it's a fairly good machine if you don't want to invest a little bit of time and get more out of it."<br /><br />I bought it primarily to get a look at the software and agree that the settings options you're given aren't extensive. My current feeling is that their software, limits for settings notwithstanding, is the best out there. This edge is largely due to the breakaway support capability.Forrest Higgshttps://www.blogger.com/profile/17208965471464716174noreply@blogger.com
