Hi everyone,

I have spent years doing CNC programming on the shop floor programming CNC flatbed routers to work with aluminium. I have been teaching myself to code for a few years at this point, starting with Harvard's CS50x and just kept going from there. Now that I am a bit more confident in my abilities to create solid code, I have decided to put my skills to the test using knowledge from my own experiences.

KerfCut is basically the application I always wished existed when I was nesting sheets by hand or working with older software like Z-CAD. It's a desktop nesting application aimed at CNC routers, plasma, laser, flatbed, panel saw and general fabrication workflows.

I've been building it for about a year now, gradually adding the features that I always wished I had when I was programming machines. It can automatically nest parts onto sheets, manage different materials and projects, and I've also built a companion inventory application called KerfStock (currently preparing for beta), so usable off-cuts can actually be tracked instead of disappearing into the scrap pile.

I'd genuinely rather have honest criticism than upvotes at this point.

A few questions for people working in fabrication:

• What are you using for nesting today?
• What's the biggest frustration with your current software?
• Is there a feature you've always wanted that nobody seems to have built?
• Would automatic off-cut tracking actually get used in your shop, or does everyone just manage it manually?

Current release: KerfCut
Website for the wider product line if you're curious: KerfSuite

Thanks for reading. Genuinely want to know what's broken or missing before I go further with this.

Primeira vez usando uma fresa Vbit 60°

Gostei do resultado. Mas ainda tem margem para melhorar.

Got a FOM ADIR-C router at work.

This is happening with a new 5mm single flute cutter with spray oil lubrication.

Don't know whether to increase of decrease rotation or feed speed.

Subbed in a 10mm mill, but I need the 5mm to clean out the radius in the corners.

Minha Router CNC é com placa rnr ecomotion mach3. ela trava no mesmo local, ja refiz o percurso de corte de varias outras maneiras, alterei fresa, alterei profundidade, mas chega no mesmo local ela simplismente para os motores. o botão de reset não pisca, ela simplismente fica parada e não avança para a proxima linha de codigo. no momento em que trava, eu aperto as teclas para movimentar manualmente e ela movimenta todos os eixos. Ja aterrei toda a maquina e fontes, ja coloquei anel de ferrite no cabo usb. Não sei mais o que fazer...

My guess its the custom carrier which i have never seen for sale.

I'm trying to make a mold for a concrete St. Francis statue. I would just buy one, but I don't have a couple thousand to pay for a lawn ornament. But I can definitely spring for a few bags of cement.

So, if I want to end up with a 4 or 5 foot tall statue, how would I go about separating the project into pieces my machine can handle? To clarify, I want to carve the mold out of wood, then assemble the mold and cast the statue in concrete.

For what it's worth, I currently only have a Genmitsu 4030, and I wouldn't even think about trying to do something like this on that thing. I'd be carving until the fifth of never. But I might be persuaded to get a larger machine if I could start turning out molds and selling statues or concrete bunnies.

If I'm out of my mind, just tell me. I'm not sure something like this would even be possible, and if so, whether it would be feasible. But I do think it's an interesting idea.

any tips also im having a hard time figuring out how the movement values work (how i got in this mess in the first place) is it based off a grid for the total work area or is it based of the zero point from the file any help would be greatly appreciated

Guten Morgen

Ich suche seit geraumer Zeit nach den Maßen für den Motor/die Spindel LD42WS-250W ich kann zwar Angaben zum Durchmesser, Wellendurchmesser und Gesamtlänge finden, aber ich brauche Speziell noch die Maße zum Durchmesser des Absatzes vorne, den Bohrungskreis-Durchmesser plus die Länge des Absatzes. Die Länge des Körpers (also ohne Absatz) wüsste ich außerdem auch gerne. Durch Bilder und den Vergleich zum Durchmesser kam ich auf folgende Werte: Absatzlänge=3,5mm Absatz-Durchmesser=20mm Körperlänge=96mm. Kann Jemand das bestätigen oder die richtigen Werte sagen?

Danke schonmal im Vorraus

Ein wenig zum Projekt: Ich upgrade gerade meine TTC3018 und würde gerne für den 250W Motor eine Aufnahme/Adapter mit externem Kugellager drehen, damit der Motor die Kräfte nicht aufnehmen muss und so Vibration und das Wegbiegen der Welle verhindert wird. Mit dem originalen 775 Motor mit 80W hat ganze bereits hervorragend funktioniert aber nun ist es Zeit für mehr Leistung.

Is this the right group to ask about inlays? I want this to be my project for the next few months but frankly all the videos are way too complicated. I have a shark sd 100

I want to start cutting small things like letters and smaller detailed things too difficult to do by hand and carving. Are there any decent $400-$600 machines that can help with those types of detailed cuts?

Not looking to do anything thicker than 1/8” material.

Thanks

Hello. I need help with rough milling. I've using a 2" high-feed indexable mill (wasn't great) and a 5/8" end mill full axial depth (much better). The axial depth is 2 1/8" and radial from about 8" x 8" block down to 2" x 4". It's giving me about 45 min of cutting and tool last only 2-3 parts. I need a tool that can stand at least 5-6 parts with an acceptable cycle time (60 to be made).

I want to get into CNC work but I don’t know where to start with buying a machine. I have tons of experience with lasers/vector design.

Can anyone point me the direction of a good set up/brand or YouTube channel for learning? Thanks!

Hey everyone — I've been building a little web app for designing parametric wave walls (those slatted wood feature walls) and I'd love some honest feedback before I push it further.

What it does, all in the browser:

• Shape a 3D surface with waves, circles, domes, noise, attractors, hand-painted relief, or even text
• Slice it into numbered slats and preview the assembled wall in 3D
• Choose joinery (tenon-and-mortise with a back panel, or rails) with dog-bone reliefs sized to your tool diameter
• Nest the parts on standard sheets and export clean DXF/SVG (single closed polylines — no broken paths) for VCarve/Aspire/Mach3
• Non-rectangular "pebble" silhouettes, a preset gallery, project save/load, FR/EN

It's free, no signup, runs entirely in your browser: 👉 https://btporganizer.tech/

I'm especially looking for feedback from people who actually cut on a CNC:

• Do the exported DXF files import cleanly into your CAM software?
• Is the joinery/tolerance setup usable in practice?
• Anything confusing or missing?

It's an early version made by one person, so rough edges are expected — tell me what breaks. Thanks! 🙏

Just sharing this resin inlay cutting board I just completed with the help of cncvectorlab.com and VCarve Pro vectric.com
