3D Printing : Trinus3d Printer from Kickstarter Odd behaviors? - Part 2


So after a few more experiments with turning on/off smart infill, going from 300 microns back to 150 microns, and even speeding up/slowing down the print speed, I can only get that ribbed pattern to appear on the one print where I'm printing nine pillars all at once!  Weird!  The last pic above is when i printed two pillars at the same time.  I was printing all of my other experiments one pillar  at a time.

So I imagine the cause is the movement from pillar to pillar when printing is just causing some weird pattern to emerge.  I've also seen people mention those wavy patterns in thin walled  print with the fan at 100% and the force of the air causing the pattern.  

However at this time I'm done with the experiment as I have a ton of pillars, and done currently anymore!  Hehe.



I've also  started using them to actually organize my cables and pens around my desk with some magnets!



Here you can see I was trying out a different design buy using two different pla's, which i kind of like.  Truth  be know I was running out of polymakrs translucent yellow pla and just switched to their white polymax!



I used the following adhesive and magnets to "glue" the pillars together and then to add the magnets to the tops!  These are my affiliate links which helps out the blog/youtube channel, etc.  You could also use my shop link!

3D Printing : Trinus3d Printer from Kickstarter Odd behaviors For Certain Prints?


UPDATE: Additional findings and possible conclusions!

All sliced in their software Pango - So I have a couple of prints that I was doing I derived from http://www.thingiverse.com/thing:961176 . I printed the initial hive file (or a remix actually that just added windows to the back to snake your cable through) and with the initial print I kept getting this terrible banding along the z-axis which I thought might be z-wobble but it seems a bit too "wide" to be so, so I'm not sure exactly what this is or how to fix it or what causes it.

If you run your finger along the walls you can feel the bumps so its not just within the print. could this be a result of some kind of weird infill (which i think i had set to 20% but as you can tell the walls are thin enough where it doesn't do any infil.

I think created a completely separate file and model (just a single hex pillar and then was going just glue them together in any config I wanted) but was still seeing the banding despite not using any bit of the other file as you can see here...


then just to check to see if there is an issue with the printer I did a benchy after printing out the single hex pillar and the benchy came out practically perfect. So again i'm not sure what those bands are...

I think the only diff in settings is that the banding hive/pillar is 300 microns vs 150 microns of the benchy or whatever pangos initial slicing is...


any ideas, suggestions, or if others have seen this behavior, any info would be helpful. The hive cable storage is still very much useable and the banding doesn't really effect the projects i'm currently doing just don't want it effect the quality of project later that might rely on perfect finishes and or accuracy...

thanks in advance!

Disappointed : Shaper Origin - The Handheld CNC That Could Have...



Just released today for PRE-ORDER: https://shapertools.com/ Is the Shaper "Origin". Its essentially a handheld CNC machine that you can use almost anywhere on almost any surface and the computer compensates for less than accurate cuts to give you perfect/near perfect cut.

Here are a few videos of it in use:

Link 1 Make Magazine's Coverage of the release.

Link 2 Applied Science's Coverage of a beta prototype in use.
This is a very exciting technology, and was giddy until the release announcement. I hate to say it, but with the "release", I'm disappointed overall. 

The announcement today was/is essentially nothing more than a self run kickstarter where you can "pre-order a unit".  A unit NOT in production.   So there are all the caveats of dealing with a kickstarter project, and more so that its NOT actually ON kickstarter. 

When speaking to most of the people around the maker booth at the last two bay area maker faires, these individuals seemed to indicate, along with other marketing emails recently sent, that they were close to production.  

When I hear that kind of talk, to me that indicates they have everything set up and will start producing units in a few months, and depending on when you preorder you should be seeing production units out in the wild. So with their emails of an exciting announcement, I was expecting a Oct-Dec delivery.  What we got was a we're thinking of Sept 2017 time frame.   A Sept 2017 "expected" delivery! Thats a YEAR away! Of course which they charge your credit card as soon as you preorder.  So you've given them a interest free (for them) infusion of cash, while you pay that credit card off.

Which, just like kickstarter if something were to go wrong, oh like someone buying a house with the starter monies, and then they try to "fix" whatever goes wrong, but ultimately can't deliver anything except for an apology email about all of their good intentions, you'll be left holding your empty money bag. This is because most credit cards have limits on the length of time you can apply for a dispute/refund and a year is usually MONTHS too long to dispute anything.  Sure the company can say they offer a refund up until it ships, but if it never ships, and they don't have the money to refund anyone, you'll end up with ZERO monies, and ZERO product. 

Another issue I was disappointed on was with the price. Shaper indicated over and over, in person and in emails that the target price would be around $1500. Then they said well for early birds/pre-orders, etc. Then the actual announcement and they list them for $1499. That's kind of a douchey move if you ask me $1 "under" so they can be "technically right about the $1500 statement" for early birds. 

But wait if you're one of the early early EARLY birds you can get it for $1299!  With that said there are only a "select few", which screams "you're part of the open beta test!", that can get this price. Retail is going to be $2099.  WTF? I talk about that more below.  

In addition another disappointment, is they're also using a "custom" spindle but all of their "demo's" have been with dewalt routers, which appear to be the $199 (or maybe the cheaper versions), and if they've switched out the spindles with a "mass produced silent and cheaper version", like most of those cnc kits out there, most of those users end up switching out to the said dewalt router, or similar, because of speed, accuracy, and durability.  This last bit is just speculation, but from the video it appears the new spindle might be smaller, and possibly you wouldn't be able to do a swap out??? If so that means you have to rely on them for swap out / repairs. Which isn't good.  Isn't good at all! 

Lastly,  there is that price again $2099 for retail? WTF. This appears to be nothing more than a compact computer, hopefully not just a raspberry pi, or similar, which might justify the price a bit more, and a inexpensive router. So why is thing even over $1000 bucks? 

The items that make up the unit are likely not more than $500 bucks. I would expect a price of $799, $899, with a option to go with a more powerful router for $1000 even or better still a $699 version where you bring your own router. Also $10-15 for a roll of the tape is also pricey, which they say you can only get through them, though Applied Science's video of an early prototype where he's cutting metal i think he indicated you could print out the registration marks.  Which Shaper should allow, the printing of the registration marks rather than rely on the stupid tape route.

I was whole heartily giddy for this product, and was up at 5 am PST to put my order in when they announced it and made the site official. Once I got the email for the early bird "your special" price of $1299 with the stipulation of "you'll get you're unit in Sept of 2017", a year! and to be honest,likely LONGER because no one hits their dates, ever, and its far more likely a early 2018 time frame delivery, I was so, so, so Disappointed. :(

I'm skipping this entirely now, unless Shaper wants to send a unit along for a REAL HONEST review and going back to pricing out and looking into getting a desktop/workbench cnc machine.  (unless glowforge gets off their asses and sends me out my laser cutter! yes i've been burned before on these types of things which is why i'm advocating against others doing so AGAIN!)

Who knows maybe the maker community, like the 3d printer, can come up with a cheaper/better solution for the masses.
