I just got a quote on a 600mmx600mm heatbed in China and would like to know the ideal specs (voltage/wattage/etc.) to get it running off an AzteegX3. Can anyone help? I ordered from the place +Thomas Sanladerer​​ suggested in his HBP video, thanks BTW!

+Whosa whatsis ouch, thats a hefty price on the McMaster one. You can likely remove a decimal place on that price by purchasing through alirubber (and have them install the redundant thermistors to boot).

For SSR I am a big fan of Omron G3NA family. I have used them for years in industrial control cabinets. They are ubiquitous, and dirt cheap on eBay (but avoid the knockoffs).

I use the Omron G3NA-220B on mine (last two numbers us the max amp rating). Unlike the cheap fotek SSR people tend to get on amazon the Omron run cool as a cucumber.

Help! I can't find the prusa calculator that had 1/32 micro stepping for drv8825 drivers. I've used it a long time ago. I found the regular calculator on reprapbbut no 1/32 option came up.

just do what Thantik said. Take the number that 16 gives you times 2. No need to over think it.

Interesting, but too expensive for what it is I think. Anyone interested in developing an open source miniature hot knife?

After meeting the lovely  +Sanjay Mortimer  and +Joshua Rowley  at MRRF,  +John Driggers  and I decided it was time to get up off our backsides and install the E3D cyclops extrusion system.

I designed a mount for the hotend (I don't just do dragons:-P) and we were ready to go. This is our first test print using out of the box settings. 

So far, you can colour me very impressed (no pun intended). There are some bogeys, which when removed leave a bit of a seam, but I am guessing some tuning and/or sanding could get rid of that.

Next print up is a re-sculpted Aria the Dragon, specifically designed for dual extrusion. I've wanted dual extrusion for ages as from an artistic point of view I can see real potential.

I'd really like to mimic the shading effect you get in the purge tower, I have some ideas on how to do this, it's just whether slicers will want to co-operate:-)

+Jeff DeMaagd What do you propose to change in the Cura tower? I know it's currently sub-optimal, and we will be changing things for the tower in the future (also, placement, and more then 2 extruders is problematic)

So I am having issues getting my printer moving. I have connected to my board to both Repetier and matter control. I know that all my motors will turn in both directions because I reversed the polarity in each. My y-axis will respond and turn in both directions fine. My X-axis will move one way and then it will move in the opposite direction when I tell it to go the same direction again. Also my z-axis will only go in one direction; and it would only move when it was told to move with the positive direction. Even if I flipped the connector, it would only listen to the positive command. ( when  I flipped the Z connector it would just move in the opposite direction, but only when I clicked the positive command on repetier or matter control.). Could anyone help me with this?

Could it be something with my firmware?

+Jeremy Keckler m119 is basically a command that you can tell the printer to do in a software like pronterface. What it does is it asks the current positions of the endstops and since the printer already has firmware on it to recognize the command it will spit back information pertaining to what the command asks.

Non-planar slicing for that particular object can be done in a standard 3D printer, though it's probably a bit nicer with a 6DOF machine.

Hiya, we are running a survey (it takes only 5 min). If you complete it before Easter, you could win a 3D body scanning session! Your answers will help a tech start up off the ground and we would be more than happy to share the results once we have had a chance to analyse them.
 
You could win a 3D body scan and prints for you and your mates

3Dify is helping to bring 3D technology to the masses! Whether you're a hardcore technologist, a digital dabbler, or someone whose only tablet is kept in the medicine box, we'd love to hear what you think.

All those who complete our quick survey http://goo.gl/forms/cXCi21vbZB (5 minutes - we promise) before Easter will be entered into a prize draw. The winner will be invited to bring themselves and three friends or relatives to 3Dify's studio in Brighton where you'll be scanned, made into interactive 3D images which you can embed in social media, and have 3D printed mini sculptures of yourselves sent to you.

Hi
 I want to chat with someone that haves a Makerbot Replicator Z18, and experience with it, i have one and i'm experiencing bad results, and going crazy with it...still have hope.

Anyone?

.1mm prints are tough to pull off without extremely accurate bed calibration. You should be thankful that your Z18 is printing at all. Most of them end up as $6,500 paper weights.

I'm teaching a summer workshop on 3D printing.  I will be covering basic CAD design (autodesk fusion) and FDM printing (ABS/PLA) on consumer level machines (a mixed bag: Printrbots, MB Replicator V1, Lulzbot Taz).  The student base is comprised of university undergraduate visual artists and designers.  

Do you know of interesting projects, people, or approaches I should research?

Thanks in advance for the feedback!

+Nick Kloski​ yeah, for sure! I can give an assignment on mashups. I will probably give a class to meshmixer.

Maybe before we get into drawing our own designs. It might be a fun way of getting used to navigation 3D space and modeling fundamentals (xyz coordinates, mesh structures, faces, Boolean operations, etc)


It's support generation is interesting as well, though I haven't used it.

So I need some feedback with printing on PEI. I have been testing with it for a little while now and have had some serious frustrations with getting ABS to stick all around. I seem to finally have some success but it took diffusing my heater with an aluminum plate to spread the heat and when I still was having issues wiping the PEI down a couple times with acetone followed by wiping down with iso alcohol 91% to get things to stick to the surface. (Got my PEI sheet from McMaster. 0.04" thick sheet)

What other methods are people using to get ABS to stick to PEI?

In my experience, 100C degree (of surface, not thermistor read value) is optimal value for ABS on PEI.
And never swipe PEI acetone when it is still hot, which result ruin characteristic of it.
I'm using Iso alcohol these days.(also use it when cooled)
