Well hope no one minds me flooding this thread with reply's.. I kind of have to do it in bursts these days, esp since I get so behind... Any ways my 7am alarm just went off .... and i havent been to bed yet so im out. Tomorrow is a big day to because were moving our hacker space to a bigger location, been planing that for 6 months and now the day is here! Thanks for all the great input everyby rylangrayston - Polar Machines, SCARA, Robot Arms
Quotetimogiles I've been working on a single mirror galvanometer design also. I just put my design up on thingiverse and I figured I'd share with you guys. http://www.thingiverse.com/thing:179041. It's a work in progress but I'm making pretty good headway on it. I've ditched driving it straight from a headphone jack, if I'm going to build a printer based on this method i'd rather have it dediby rylangrayston - Polar Machines, SCARA, Robot Arms
QuoteDino @tag16c thanks a lot !!! I have understand your circuit . You can move the mirrors 20,000 times per second ( if the galvos/hardware can handle it) thats right? And JamesCooper and the peachy team are do'nt working with 20kHz audio out, instead they are using a lower frequency sine wave and handle the amplitude peak with cap and diode. thats right ? For the printer they don't needby rylangrayston - Polar Machines, SCARA, Robot Arms
QuoteSpelljammer I too have been working on a single mirror design. This is just a mirror held balanced on a center fulcrum by 4 small rubber bands. There are 4 coils and 4 magnets. Each opposite coil and magnet work together. For instance, to move left, the X coil 1 and coil 2 energize, the magnets under each is set to the opposite polarity, the right one could be North pointing up and the leftby rylangrayston - Polar Machines, SCARA, Robot Arms
QuoteJamesCooper These are very good points, both of which we were aware of. Rylan's early prototypes used a second surface mirror (he once used old CDs), but I believe he is using first surface mirror for the recent prototypes and will definitely be using that in the final version. As for the pivot point, it gets a bit tricky. To make this simple to build as a kit, we are currently using a tensiby rylangrayston - Polar Machines, SCARA, Robot Arms
QuotePaulP @Spelljammer This is along the lines of what I was thinking for potential causes of the warping. I think the pivot point comment is particularly on the mark. It's hard to tell without seeing the designs; but I think part of the problem is that the position of the center point is in the middle of the thread - not actually at the mirror (front or back). This would change the distance fby rylangrayston - Polar Machines, SCARA, Robot Arms
QuoteSpelljammer I wanted to mention the mirrors and their odd warping of edges on a a straight line. The mirrors are a second surface type which will eat up about 10% of the laser power going in and another 10% coming out and even more at more severe angles. So, two mirrors eat up about 40 to 60% of the laser's power. They also have a ghosted reflection artifact because some of the light bouncesby rylangrayston - Polar Machines, SCARA, Robot Arms
QuoteCharlesNeville Turning the laser on and off with a minimum of cost. There are many bands of audio in the speaker output that aren't useful for controlling the mirrors. They can be used for other control signals. To turn the laser on and off, you could inject a low amplitude, high frequency signal; eg 18kHz, -20db into the output of both L & R outputs. This could be filtered out withby rylangrayston - Polar Machines, SCARA, Robot Arms
Quotekoopa Hey guys, Like many of you, I was fascinated and enamoured with the $100 photo-setting resin printer made in a very Macgyver fashion on Kickstarter. In the spirit of collaborative work, I sent some ideas to the creator to further refine/innovate the design on low-budget, which he appreciated and told me to post here. Feel free to build/add/utilise anything here, chuck in an idea or twby rylangrayston - Polar Machines, SCARA, Robot Arms
Wow rather sorry I only Just found this Thread now ! Of course ive been really really busy and on the peachy, so have many of you!!! Ok so ill try to catch up and reply to a bunch of these Great posts. I haven't read this hole Tread yet but I can tell there are alot of ideas here that im also working on and probably a hole bunch of new ones not yet conceived of at peachy and a huge thumbs uby rylangrayston - Polar Machines, SCARA, Robot Arms
The thickness of the resin on the water has no effect at all. one needs to put enough resin in so that it dosent run out before the end of the print... the software will tell you how much resin to have in place for your print.by rylangrayston - Polar Machines, SCARA, Robot Arms
The fact that the resin is contains by the raft really helps solve the problem of the linear beings gumming up. if we use nylon rods no corrosion ether The surface of the water will keep the hole thing floating nice and flat in a very still room. so we may not need to have liner bearings per say .. more like just thin holes that make point contact like this.

hmm perhaps a modorator can make a section for the peachy printer? and move the peachy threads there. not sure where all these treads belong... in only know of the 3 in the polar bot aria where are the others?by rylangrayston - Polar Machines, SCARA, Robot Arms
ok so in this supper ruff animation you can see how I was thinking we could do a rotaiting raft. everything your see here would happen in the bottom of the peachy printer. color key in vidoe: Brown - floating raft that separates resin Red Green Blue Yellow - Resins held separate by the raft Gray - solenoid and raft center shaft The raft would be spun by electromagnets that could also be triggerby rylangrayston - Polar Machines, SCARA, Robot Arms

The Idea was originally posted here: http://blenderartists.org/forum/showthread.php?308988-Blender-Runs-new-3d-printer-costing-only-100-dollars! basically it could allow multi color prints and multi material prints for example you could print a figurine with hard plastic legs but soft rubber knees, and neck.
