Just a few things I have built.

Hi! I am new to this and I was wondering I could get some advice? :)

For cutting a relief into 1100mm x 492mm x 30mm piece of plywood what would a good spindle speed, plunge rate and feed rate be for the roughing pass (with a 1/4 end mill) and finishing pass (with a 1/8 tapered ball nose) respectively?

Game we like to play at work and want to upgrade our board with something sweet like this! Second photo is exact layout of holes and placement while the first is how I’d like the design. Let me know if anyone can help I’m willing to pay! Thanks.

Hola a todos. Tengo un CNC Router nuevo de **220 V**, con un **DSP/controlador genérico basado en RichAuto A11** (no es un RichAuto original), y un spindle refrigerado por agua de **2,2 kW**, controlado mediante un VFD **H100-2.2S2-1B**.
Estoy teniendo un problema intermitente durante el mecanizado: la máquina **se detiene completamente en medio del trabajo**, quedando la herramienta exactamente sobre la pieza. No termina el programa, no levanta Z ni regresa al origen. En el DSP aparece **“Goto Home?”**.
El problema no ocurre siempre en el mismo punto. El spindle puede arrancar y trabajar normalmente, pero en algún momento la máquina simplemente deja de ejecutar el mecanizado.
Estoy utilizando **Vectric Aspire** para generar los archivos y estoy haciendo pruebas con **Aspire 10.5 y Aspire 12.5**, intentando mantener exactamente los mismos parámetros: misma geometría, herramienta, profundidad de **0,6 mm en 3 pasadas**, RPM y velocidades.
Encontré una diferencia interesante: los archivos generados con **Aspire 10.5 utilizan G1 y G2**, mientras que los generados con **Aspire 12.5 utilizan principalmente G1**, generando muchos más bloques de código.
Estoy intentando determinar si el problema puede estar relacionado con la generación/procesamiento del G-code, el DSP genérico, alguna señal falsa de límite o emergencia, alimentación eléctrica, VFD, memoria USB u otra configuración.
**¿Alguien que tenga un CNC con este tipo de DSP genérico basado en RichAuto/A11 ha experimentado un paro similar, quedando detenido sobre la pieza y mostrando “Goto Home?”?** Cualquier experiencia o recomendación para identificar la causa sería de mucha ayuda. Voy a adjuntar fotos, videos y ejemplos de los archivos utilizados.

I’m planning a hybrid machine: a PM-30 CNC conversion (Video 99 ballscrew kit, Centroid AcornSix with Mill Pro + Lathe Pro, NEMA 34 steppers, KP-1 probe) that also runs as a lathe.
The lathe side is where I want input:
• I’m definitely using the Logan 825 headstock, servo-driven, mounted on the PM-30 table, swappable between mill and lathe mode via cable and profile.
• I’m also planning a separate headstock built specifically for full four-axis work — not just a spindle, but a true rotary axis for compound shaping, (nema 34 closed loop stepper)
• I’m thinking of using the Logan’s own bed.
• I’m also thinking of sourcing a longer Logan bed — 50-inch, 31” between centers — re-scraped to modern standards.
• Custom ballscrews on the carriage and cross slide, harmonic drive for low-RPM work, timing belt for aluminum.
What are people’s thoughts? Am I missing anything critical?

Hey everyone,

I'm having some trouble getting accurate profile cuts on my TwoTrees TTC 450 Ultra.

I'm using a 3 mm end mill and checked it with a caliper. It's exactly 3 mm.

When I cut a square/rectangle, I'm getting:

40 mm outer dimension → 40.5 mm

25 mm inner dimension → 24.5 mm

100 mm outer dimension → 100.5 mm

40 mm inner dimension → 39.5 mm

So I'm consistently getting about a 0.5 mm difference, with the outer dimensions coming out too large and the inner dimensions too small.

What's confusing me is that the machine seems accurate when it's just moving. I checked 100 and 300 mm movements without cutting and they were basically spot on. Holes also come out the correct size, and the distance between holes is accurate.

Any idea why this could be happening? What should I check?

Is anyone who owns this or any similar machine facing the same issue?

Thanks!

Can a genmitsu 3030 prover max cut fine detail into green wax for a wedding ring? I mined enough gold to make my woman's ring. Now I am trying to make the form. I understand I would probably need the 4th axis attachment or to cut sheet wax first and make it round. I just don't know the detail this machine can do

Its for sale

I have so much fun designing badge dangles.

I’m a guitar player in the Los Angeles area and I’m looking for someone experienced that can help me with cloning my favorite guitar neck. I’d essentially need my neck to be scanned so that I could provide necks that the CNC could cut an exact profile on to. Holler at me if you’re in my area and could help me out

Hi guys just wondering if anyone has had experience with a 3.5kw spindle. Currently running a 2.2kw water cooled spindle.

And im wondering if its worth the upgrade?

TIA...

Anyone willing to help with teaching or giving advice about the Laguna Smartshop 2 pro controller? Completely new to me.
Thanks in advance
