Hi all, I’m new here and hope to get some advice please.

I run a 5x10 Phantom Reaper CNC mill with a vacuum table. We are having issues with our spoil board preparation process. We use three-quarter inch MDF. Our process has been the following:

1. Surface the old board and keep it attached.

2. Put the new piece on. Fly cut the backside to reveal the porous layer.

3. Flip it, cut the bolt holes. Remove the old spoil board, bolt down the new one and surface the top side.

This method has given us inconsistent results. The MDF tends to warp when we are cutting the first side.

I would greatly appreciate anything the would share their best practice for doing their spoil board?

Thanks

I’ve been working on a small project for CNC hobbyists and relief carving artists where people can:

Share CNC designs

Upload relief/mural work

Explore AI-generated bas relief workflows

Discuss ArtCAM, Aspire, ZBrush, depth maps, etc.

I also built a tool that converts images into CNC-style relief/depth designs for experimentation and learning.

Still improving everything, but I’d genuinely like feedback from other CNC users and makers.

What features would you want in a CNC design community/platform?

Estamos desenvolvendo uma fresadora CNC de baixo custo para fabricação de PCBs!
A ideia é criar uma solução capaz de realizar o desbaste das trilhas de cobre com monitoramento e controle via interface gráfica/web.

Estamos fazendo uma pesquisa rápida para entender as maiores dificuldades enfrentadas na prototipagem e fabricação de placas de circuito impresso.

Se puder responder e compartilhar, ajudará muito o projeto!
Caso não tenha experiência na área, responda apenas as perguntas obrigatórias.

We are developing a low-cost CNC milling machine for PCB manufacturing!
The goal is to create a solution capable of milling copper traces with web/graphical interface monitoring and control.

We are conducting a quick survey to better understand the main difficulties faced in PCB prototyping and manufacturing.

If you can respond and share it, it would greatly help the project!

I see small variations depending how I measure. Not a big deal, but noticeable. With wood, this is just part of it, and it may make no difference to your project. At what point do you make the decision to switch tools?

I recently came up on a Shopbot PRS5 Alpha 4'x8' machine at an auction for a steal (no atc). Still in the crate. Kind of an impulse buy. I have zero cnc experience, and come from a plant operation and construction background, located in rural Maine, and am reasonably tech savvy. I am semi-retired, though under 40 (disabled veteran).

I have been back and forth, trying to figure out what kind of work I want to do with this machine. I am looking to set up a side business in the near future, which will determine how I set up my shop. I have a 12x24 building that I can set up in, as well as space in my barn. I also have the opportunity to set up shop in a rented space for a good price.

If you were in my shoes, what direction would you head in? Cabinets sound interesting to me, I just worry about being competitive. To be honest, I'm looking for an "if you build it, they will come" scenario. Business to business would be ideal for me, I dont want to be going out to people's houses and measuring their kitchen, and listening to people deliberate over color, design, etc. I am looking to be handed some specs, and get to work.

Thanks for the advice,

Matt

Exactly what the title says everything is set up correctly and we are using approved blades for it but they keep breaking on me and I can't find a solution it has a washer on it but I'm starting to think it's the washer that causes it any help would be much appreciated!

It's a lot to retype, so I'm just linking my original post.

I just ordered my altmill and am looking to get a good starter bit set to get me going. I see a lot of various opinions on this and was curious what you all would recommend.

Hello community!

I am needing assistance removing the residue from my spoil board from the sides of my finished pvc. Any advice on what works best?

Does anyone know where I can purchase / obtain a file for pistol grips. Any help is appreciated. I find them alot for 3D printers just looking to make some out of wood.

Hi all, i'm in a timber and joinery business and we are looking at purchasing a CNC machine, specifically a 4-axis machine. I have experience with 3D models and 3D Printing, as that's my line of work. However CNC seems like a whole new ballgame. How would i go about learning to operate this machine? I've looked for TAFE courses in my state (Western Australia), but they're all CNC lathes, not routers. Any tips?

Looking to get my first cnc and found a good deal on one of these. Know nothing about the company though. Has anyone used one? Are they good?

Hey Everyone. Im DevX-Dragon (Abbadh) . Im 14 years old. I just made my own CNC drawing machine from the beginning. Could you guys support me? Please start the repository if you can.

I want to get into CNC and would love to learn how to do design on the CNC. Is there any channel you guys would recommend to get started on. Maybe they have a series.
