Learning, trial and error (and fun!)

I’ve been putting my MPCNC to work trying to learn the ropes of CNC milling. Here’s a few of my first attempts…



I am seeing a little bit of “jumping” on the gantry though. Can any of you CNC ninjas take a look at this video and tell me if that seems like to much:

“Jumping” a bit

Is that excessive?



BTW In the near future I’m going to take a stab at making XZ plates out of aluminum for my upcoming LR3 build!


Seems like the core clamps are not tight. :scream_cat: The results are incredible though.


So is the greed lasered? Or what process, looks awesome!

Yeah, lasered and thank you!

BTW I only learned the dice game Greed (aka Farkle/Dice 10,000/Dix Mille) about 6 months ago but it’s really hooked me! It’s terrific fun with a group of people. I highly recommend it if you haven’t played it yet.

Farkle is addicting… I can attest to that.

Yeah, make sure you don’t have any cracks in the core clamps.

Nice work!

Just get in the habit of checking all bearings touch and there is no movement before each job. I do this as a preflight check regularly as nylock nuts can and do loosen up from time to time. After 2 years of heavy use, i have not found a crack.

Thank you all! I will check the core clamps today after work!

I agree that it should be the case but I’ve had to replace 3. I started having multiple part failures, all from the same filament, so I assume it was bad.

The cracked cores produced similar movement as what was in the video and it was a little hard to diagnose since the cracks were not visible at rest. I finally found the problem when I manually lifted the core and I could see the separation.

Hopefully it’s just some loose bearings.

You mean Zilch? :slight_smile:

Greed is the best name IMHO.

Yep, very similar.

Here in central PA it also goes by Amish Dice by some people. It makes me smile to think of a couple of Amish farmers shooting dice onto a piece of cardboard behind the chicken coop!

I’m intrigued by the dinosaur in the room :slight_smile:. I haven’t done 3D contouring yet. I’ve only been using my Primo for four years. One of these days, I’ll get to it. I like your dust collection. Very nice work! I’m going to go learn Greed now.


It’s so much fun!
