7th grade project

i’m hoping he’ll go with fusion360 as well since it
seems to make sense that it’s all integrated.

he’s worried the learning curve is too high.

Since he has some experience already with CAD, the learning curve shouldn’t be too high. It took me about a week of playing around to start to get comfortable with it. I do have a lot of prior 3D CAD experience, however. Before Fusion, I had been drawing in Solidworks, Creo, AutoCAD, and Rhino since about 2011.

For a crash course in the user interface, Lars Christensen does a good job in this video:

I found these YouTube tutorials very helpful when I was first learning Fusion. They help cover building assemblies from sketches, user variables, nesting parts, and setting up CAM toolpaths.

I made the flat pack stool from the second video here.

More obtuse but totally free and can do 2 & 3 is Blender.

There are options to get .svg exports. I also see options to .dfx My son jumped in to blender at about 16 and is now 23, he can kick out a design pretty fast. Lots of youtube on how to get going.

Thank you


I actually learned how to 3D model in Blender at about the same age as your son. At the time, I just made spaceship models and a couple of Warhammer 40k vehicles for a mod I was helping out with. It’s a great program for learning to model, and I’m sure it’s progressed since I last used it.

another question.

suggestions for hanging mount (safety chain) for router?
i’m thinking he needs something to keep the router from falling when hooking
up chains, etc. by himself.

A common solution to the problem is to hang the sled from the top beam when it’s not in use. It helps loading/unloading plywood onto the machine if the sled is out of the way. See my post in To rest or to hang for more details.

The safety chain would probably work if it hung from the top beam and was on a quick-release (like the stock chain mounting).That way, it could be disconnected while the machine is cutting. It would still be in the way for loading or unloading, but may be easier to access than if the sled was up at the top beam.


so far so good. starting to install motors when i left.


Keep up the great work!

We don’t yet have a Unistrut frame in -

Is this one designed from @dlang plans?

Thank you

he used pictures and list from @bdillahu and then modified a bit
based on info from forum and his own ideas.


what’s the diameter of the holes in the brick holder?
he can’t seem to get the makercam to create a cut.
is it a drill instead of profile?

i think we’ve hit the part of the curve that is a bit steep…

iirc 1/4"
not a critical dimension, you just have to have botls that hold

If the bit size is very near the size of the hole it’s cutting, some gcode generators choke. You can make the hole size a little bigger, or lie about the bit size (say it’s .24" instead of .25" for instance). My approach for the brick holes was to use a hand drill :grin:, I was impatient!


he figured out that drill operation worked.


tried to cut sled.
this is what he got.


also won’t center.

Let’s start with getting it to center…did the calibration process go OK?

i think so. he said he did a few times and it finally worked but then it stopped.

Hmmm…can you post a screen shot of your settings window?

will do when he gets back.
time at school is done so it’ll be probably
in a few days after we move home.

felt like it’s a success that he got it set up and
cut something!



it’s working!!!
