Pulled back a bit, we can see how shallow the wobble is in the case of my RapMan. There are even fixes that you can download to replace the default Z-Axis system that came with your RapMan. They require taking your RapMan apart to replace the Z-Axis lifts on all four corners of the RapMan. My goal, in pondering a solution was to find a way to minimize or eliminate wobble WITHOUT taking the RapMan apart. MORE
I received some aluminum plates (one for my rapman and other for my mendel) and some 50W resistors (still waiting for the 100W ones) tied it all together and it worked just like Chris shown on his super cool blog :), anyhow using the max power (~12A ~500W) I can push to the bed it can overshoot the max temperature those resistors are specified to handle so I needed some way to control it. controller heated bed I2C Mendel PIC RapMan MORE

It''s been some time since I created some fixtures for my RapMan intended to reduce or eliminate Z-Axis Wobble. This block attaches the bed to the outside rods of the RapMan using 3 small bearings. The top fixture is designed to accommodate 3 bearings that attach the fixture to the smooth corner rods of the RapMan. Before posting I wanted to make sure that the fix stood up to day-to-day printing. Here is the fix as I now have it installed on the printer. MORE
The great news for me is that the platform on which their system is based appears to be the RapMan, which I already own. If I step up to the CubeX, this means I might be able to modify the RapMan to work with ceramic for my daughter.

Some of the objects I print take a LONG time and I don''t want to have to babysit my RapMan printer for the entire print time. The vertical spool holder I created for the RapMan spools worked very well. And the small hook to the left, that attached to the bottom of the RapMan helps to feed the filament extremely smoothly. Early in my quest for a spool holder, I realized that a spool holder with a bearing was my best choice. MORE
Here is the resulting print using a RapMan 3.2. Ultimately, software will determine the success or failure of 3D printing to catch on with the larger public. Attempts at easier to use 3D software are going on all over the globe. One of the most promising technologies is being explored by Autodesk. In the next few posts we will explore the implications for those of us with 3D printers. What we will see is that while it is not yet a mature technology, it does show promise. MORE
So far, I have not found a single defect in the design of the RapMan 3.2 However, the printer is only going to print as well as we have built our RapMan printer.

I will be able to prove this for myself because I purchased a RapMan 3.2 But, if not, I am sure it will be up there with the best the RapMan has to offer. I can tell you this, now that I have the RapMan 3.2 There is something VERY appealing about the " Out of the Box Experience " of the Cube vs. the " Building Experience " of the RapMan!

As much as I like my RapMan, it shakes nuts and bolts loose just sitting on a table! I have tried filament from a fairly wide variety of vendors for my RapMan 3.2. Unfortunately, I do not have a heated bed for my RapMan and without a heated bed I find it impossible to print ABS parts without the dreaded warping that ends up in aborted runs and distorted prints.

The wobble is not bad in my particular RapMan. My impression, when I compare the two Cube pieces that I have with the pieces I print with the RapMan is that the Cube is noticeably finer right out of the box.

I installed it two days ago and was immediately able to design some things that will be not only useful to me; but, other RapMan and RepRap users as well. One of the things that became immediately apparent when my RapMan was completed was that unless I baby sat the printer, the filament would not feed well. But, it did not allow me to use the 8mm bolt that came with the RapMan reel holder kit. Moment of Inspiratio n, or MOI 3D, is an absolutely wonderful application. MORE

If I step up to the CubeX, this means I might be able to modify the RapMan to work with ceramic for my daughter. If you go back to the origins of this blog and my interest in 3D printing, it came directly out of my daughter''s career as a ceramics sculptor.
3D Printed Education
OCTOBER 20, 2013
As you may gather from this blog I have been using RapMan, BfB3000 and 3DTouch machines in school for quite a long time now and have recently been using a 3D Systems Cube… But I hadn't used a CubeX. Coming up soon I will be running a training day together with the Iain from 3D Systems, showing the guys from TeachDesign how to set up and use the Cube and CubeX 3D printers.

Here is the resulting print using a RapMan 3.2. Ultimately, software will determine the success or failure of 3D printing to catch on with the larger public. Attempts at easier to use 3D software are going on all over the globe. One of the most promising technologies is being explored by Autodesk. In the next few posts we will explore the implications for those of us with 3D printers. What we will see is that while it is not yet a mature technology, it does show promise.

In the meantime, I am printing with my RapMan 3.2 I''m also happy to report that being able to turn my attention back onto RapMan improvements has resulted in finding a way to completely eliminate Z-Axis wobble caused by slight deviations in the long screw rods. Last week I was away on vacation. The week before, I''d loaned my Cube to Peyton Duncan, who brilliantly used it. This week, the Cube is visiting the Hagley Museum in Wilmington, DE.

In fact, 3D Systems, a maker of high-end systems, has embraced the low end marketplace by acquiring and marketing the Rapman, 3DTouch and BotMill products! This blog was created in 2007. Even back then it was evident that 3D printing was going to be inevitable. The only question was how soon and how costly. It was started in May of that year.

I will be able to prove this for myself because I purchased a RapMan 3.2 But, if not, I am sure it will be up there with the best the RapMan has to offer. I can tell you this, now that I have the RapMan 3.2 There is something VERY appealing about the " Out of the Box Experience " of the Cube vs. the " Building Experience " of the RapMan! To say that there are 8 billion parts to be put together to get the RapMan up and running HAS to be just a TINY exaggeration.

MATERIALS As one might expect, from the company that brought us the RapMan 3.2 Little did I know, when I posted that I wanted to change the focus of this blog to pre-built business 3D printers that the first printer that I would talking about would be a bigger sibling of the consumer Cube 3D printer! But, a surprising CES announcement brought news that 3D Systems is bringing the CubeX to the marketplace.
3D Printing Review
JULY 24, 2015
In addition to the printers that are loaned to me as evaluation units for media or special projects, I have an old MakerBot Cupcake and a Rapman in my workshop and I spend more time trying to get those old machines to print. A search for “3D Printer” on the Kickstarter.com crowdfunding site reveals over 300 such projects, dating between 2011 and now. Not all of them funded, of course.

The wobble is not bad in my particular RapMan. My impression, when I compare the two Cube pieces that I have with the pieces I print with the RapMan is that the Cube is noticeably finer right out of the box. The RapMan can print this fine; but, only after I solve the threaded rod wobble issues. In the meantime, I will be working with the RapMan printer in an attempt to bring it to this level of print accuracy and smoothness.

I have been building a RapMan 3.2 I will be using the RapMan to test designs and material handling. And, that is why buying and building a RapMan will, hopefully, give us some clues if we see the same kinds of behaviors. I have not abandoned this site. Extreme in preparation for being able to best help other new owners of the Cube when it arrives. We will need some benchmarks to be able to adequately know that we are getting the best out of our Cubes.

RapMan, Cube or Touch), taking around 25 hours to print a 60mm high chess piece – the speed only limited by the stepper motor choice and gearing. I will get a Raspberrry Pi soon so I wanted to see what can bt done with it beside using it as a server, so I found that you could use a Pi and its GPIOs to directly control the stepper drivers, fan, heater and other aspect of a 3d printer without any additional processing electronics.

Gallery Image #4: The Touchpad is Familiar and Informative As one that has the original Cube and the RapMan 3.2, Aside from some errors in reporting the pricing, the most interesting review, so far, of the new CubeX at CES, was posted on TheVerge.com Of particular interest were the pictures that they''ve posted, of the CubeX in action. Those of us that have to kibitz from afar for now, must be content to glean what we can from images that others post.

Hopefully the use of a single lead screw will go some ways towards curing the slight periodic unevenness in print layering caused by wobbling in the four leadscrews used in the Darwin and Darwin-derivative Rapman printers. Hopefully, I'll have gone some distance towards getting rid of the periodic layering behaviour that we see with Rapman. RepRap: Blog.

Some links to “prior art”: RapMan wiki and a forum post ). PP bowl printed on a piece of cutting board. I recently purchased a small sample of white polypropylene (PP) plastic from a shop in China. While it was relatively expensive at ~$11 for 200g worth of plastic it allowed me to try out printing in PP without buying an entire spool of filament.
