A redesign of the X and Z axis gantry

Rendered Image Z Axis 4

I’ve been working on improving stiffness in all of the axis. Here’s a 3D render of the X and Z axis assembly. I found that the biggest issue with the previous iteration was that it was difficult to reach the fasteners, so it was a bit tricky to get everything as tight as possible.

We ordered linear rods and bearings, lead screws and nuts, and some other fun stuff to play around with, so this design is going to implement them. Lets hope they get here soon.

In the meantime, Chris is printing out some new parts for us to test out, and so we should know how they do in the next couple of days.

Design…round two

Hi everyone! We’ve put together a prototype and it looks pretty, but there’s a couple of things we want to touch up to get the best performance out of our machines, so we’re going into the second full round of design. Our new 3D printer is due to come in the next week or two, and so are all the extra parts we ordered, including couplers, leadscrews, bearings, and more.

We learned a bunch of new things from our first design, and what we plan to do with our second design iteration will make Sienci 1 even better. We plan to give more support to all of the v wheels, lower the y axis gantry and raise the corner supports, and experiment with thicker or wider rail materials.  We also plan to make the X axis calibration much easier by allowing it to split, as well as making all of the fasteners easier to access and tighten.

Here’s a CAD rendering of what the Y axis gantry might look like:

There’s definitely quite a few things to do to really perfect the design, but every day is a (micro) step towards achieving our goal.

Tim and I ordered a new 3D printer!

Tim and I needed a new 3D printer, so we ordered one online last night. Can’t wait to make some new prototypes and new machines!

It’s a cheap one we got online for about $310 CAD. 3D printers have gone down in price a lot over the last few years. I’m excited to see what this one can do and if it’s worth the money.

We’re going to be going into another design iteration to improve the performance on all axis with some new gantries, and this printer should help us make those parts. Also, we’re planning to take some of the parts off this guy later on and throw it on the Sienci 1 to make a GIANT 3D PRINTER.

We attached the rotary tool tool to the Z axis

The rotary tool came in the mail today, and so Chris and I printed a mount for it. We did a pretty good job of it because the tool is super snug and there’s absolutely no play. We’re just gonna have to work on wire management, perhaps put an outlet at the top of the Z axis or something.

We haven’t tested out cutting yet except with a bit of acrylic. I suspect we’re gonna have to throw on a router or a spindle to cut metal, so stay tuned in for that!

We just tested the Z axis and things are looking good! (Okay we get that there’s wobble…we’re working on that)

So we’re still waiting on our aluminum shaft couplers and lead screws to come in the mail, so in the meantime, I hooked up a shaft coupler that I made at the machine shop and a 1/4″ threaded rod to the Z axis to see how things are working.

Things look pretty good! Since I didn’t do a very good job in making the coupler straight, the threaded rod is bent, and I need to tighten the v-wheels a bit more, there’s a lot of wobble in the Z axis. Once the lead screws come in however, I’m expecting way better linear movement on this thing.

Here’s a video for you guys to watch:

It’s coming alive! The X axis is moving!

So I started fiddling around again with the CNC control board again, and dropped down the acceleration speed of the motors, which stopped the motors from studdering. I haven’t tested out any microstepping yet (I don’t have any jumpers on hand for the control board), but at single step control, we got the x axis to move pretty well.

I noticed however, that there are some issues in stalling in the motor, so we’ll be trying out some different power supply voltages, adjusting current, and just seeing what works best overall.

Prototype in Progress!

Hey guys, we’ve had a bunch of hitches with parts coming up late and 3D printing issues, but we’re back on schedule and have finished building our X and Y axis.

As I write this, we have our second Y axis gantry on the 3D printer.

Once we know everything works, we can start looking for quotes on injection molding or looking for other mass production methods.

Bringing you the best desktop CNC machines

CNC (computer numerical control) milling is a subtractive manufacturing method that uses rotating tools to precisely remove material from a blank. The level of convenience and versatility, as well as the ability to cut, drill, and carve with extreme precision out of virtually any material makes CNC milling useful in a wide variety of applications.

While CNC technology is amazing, it is still out of reach for hobbyists and makers who want an affordable and easy to use solution with enough power and precision to create functional parts.

The Sienci Mill One is a high performance, 3 axis desktop milling machine that turns your ideas into real objects in an easy to use, affordable package that focuses on simple design and user experience.
