Good thread. Still mulling over the forum for projects by itself. Let's see how this thread goes.
Looking forward to seeing what everyone posts. There are some good projects out there on the web done on the M3.

There are some good projects out there on the web done on the M3. It's a shame not all of them are involved in the Forums. If nothing else, to show off what they've done.

Agreed. I have extended some personal invitations to some customers somewhat active with the machine on social media. Some folks just like to stay to their own thing, which is ok.. but it would be nice to see them here.

I agree it would be nice to see them here. Have you thought about spotlighting projects on the main website? It could entice people to post them here for you to see and spotlight somewhere on the main site.

Well, guess it's up to us to keep it going then!

Here is something that I posted on the MillRight CNC Facebook page last night: m.facebook.com/story.php?story_fbid=1773249292917212&id=1714284268813715&__tn__=%2AsIt's an A-10 making an attack run on a tank done with the laser. This is one of the files in the huge DXF collection on the resources page. The raw DXF was a little too heavy to handle in Fusion 360, but that was on an old laptop. I brought this into CamBam and cleaned it up some, then generated g code using an engraving operation. I ran that through the laseroko applet referenced in the laser documentation to remove Z lifts and to put laser on and off commands in before G1s and before G0s. Laseroko knows what to do with it... you just upload it and it makes the g code file appropriate for lasers.

Here is something else that I made. I haven't had a chance to cut it out, clean up a couple of spots with a brush/sandpaper, and stain it... but here is what there is so far. The piece is 7x7 inches and the detail on it is almost unbelievable for how much this machine costs. Process: Got it free from a website that I can't remember. I wish I could so I could give credit, but it's a website in some other language that has free CNC art that users post. I downloaded it and first tried to get CamBam to work with the STL. No luck there. Tried to reduce triangles to make CamBam play nice with it. Still no luck. I saw that they also included a depth map (black and white with shades of gray for varying depth) bitmap image. I brought it into dmap2gcode by Scorch Works (FREE AWESOME SOFTWARE) and generated tool paths. Roughed with a 1/8" (3.175mm) end mill using a 2mm step over taking 3mm step downs. I left 0.6 mm for the finishing operation Finished with a tiny little 1/16" (1.588mm) ball nose mill on a 0.008" (0.2mm) step over at about 70 IPM (1800mm/m). The finishing operation took perhaps 3 or 4 hours. Since it was 7 by 7 inches and I was stepping over at 8 thou and it spent a considerable about of time plunging from the surface to the bottom depth of 13mm on all the features, I think that's pretty understandable. The result was worth the wait. Also, here's a testament to the repeatability of the homing switches: Universal G Code Sender/My computer froze about half way into the finishing Op. It started sending commands at about a rate of one per second. I've heard of that happening before on a large job. I looked at the last few commands that were reported on UGS. I wrote them down. Shut everything down, then opened the g code file back up. I searched for these commands, deleted everything above it, rehomed, picked my work coordinate syste back up, and then made sure it was positioned to enter back into the cut properly. I hit go and it lined back up like it never stopped. You can't even begin to tell the operation was stopped then restarted.

That is some great work. The detail and precision is incredible. I have got to learn how to do this!

I've been hard at work improving (for my needs) an already great machine. Here is my latest modification, this time to the laser setup. The purpose being, I don't want my laser module getting caked with stuff from milling and I wanted it to have the same path as my mill, so something super easy to throw on an off was necessary. Some time on the lathe and drill press and bam. No real planning just winged it lol.

That's very nice. I can't imagine it turning out any nice if you had actually planned it. Have you run anything with it yet? Do you find that it stays cooler with that setup than the black finned heat sink?

Do you find that it stays cooler with that setup than the black finned heat sink? I haven't done anything yet. Did this one Thanksgiving day and haven't had time to even turn it on since. Probably won't be able to do anything until Friday.

Purpose of this thread is to consolidate projects for sharing. So if you design something you feel would be useful to the community or just something fun post it here! kb9jlo had a good design for a clamping set up and can be found here: millrightcnc.proboards.com/post/274/threadMy contribution to the thread so far is some 1" knobs for 10-32 screws that we use on our beds. I milled out a bunch for various lengths of screws. The dimensions are in millimeters. Load up the DXF and off you go. Having a difficult time setting this up in Fusion 360. I can extrude the outside of the knob but the there are 2 sketches in the center one obviously goes all the way through but the other one I think should only go down about 2mm to hold the head of the bolt. I hope I'm not confusing with my question but I am very new in this stuff. Thank you

I hope I'm not confusing with my question but I am very new in this stuff. Thank you You are exactly correct. I think I extruded my shoulder (where the bolt head rests) to 4mm. Doesn't really matter as long as there's enough material to support torque of the bolt head.
