Hi there guys, need a little bit of help in a machine I'm building.

I'm a bit confused about the x/y axis and which is which so I'll explain it in another way.

The table dimensions of my...

Thanks for the help so far. Well, after further inspection I identified at least one thing that doesn't look good, as seen in the picture below the glass ring on top of the tube unglued from the tube...

Hi there, I've been using for the last few weeks a K40 laser but only yesterday I had the time to align the mirrors correctly. I did this following a few tutorials and right now the laser is hitting...

Hi there,

I recently bought a Chinese K40-III laser cutter and I'm still debating with two difficulties.

I don't know the focus distance of the lens, it's a 12 mm lens but when I asked the...

Hi there,

Received my K40-III last week and after the needed adjustment steps like squaring the base etc... I got it working.

First step was to 3d print an air assist nozzle, now I'm building a...

Thanks for the extensive and detailed reply, after writing the thread I went to buy a end mill and exchanged some words with the shop owner who has extensive knowledge in cnc machine building and he...

Hi there guys, it's been a long time since my last post. Three years ago I built a Midi Router from Widgitmaster and I've been using it with great success since then.
Despite the midi being a great...

Thanks for the quick reply Claudio.

Hi there guys, the midi is already jogging in every axis, I used the dry teflon lubricant and movement seems very fluid.

I'm in the process of configuring the Mach3 software in order to use the...

Well, construction of the mechanical parts went smoothly so now it's on to the electronics, here is a picture of the machine:

- sorry double post -

Great work so far Eric, it looks big and heavy, is it going to be more accurate than the midi? Are you going to produce a limited quantity?

So let me see, WD-40 is to be avoided, but is also any lubricant based on the Dry Teflon a bad choice?
I think I should use the oil my mom uses to lubricate the sewing machine, it's a very thin oil,...

Hi once again, thanks for your answers, any tip on the lubricant/WD40 topic?

Also, I contacted Dave from HobbyCNC and understand now the reason for not shipping to my country and to some others...

Good evening guys,

Let me start by saying a big THANK YOU to Eric for not only producing such an amazing machine but also for taking the time to get my package together (solving the HobbyCnC...

Hi there guys, today I tried to order the 3 axis/305 motors from HobbyCNC and was informed that despite the fact that they ship internationally they don't ship to my country. In what other places can...

Thanks for the replies guys, well, my hobby is model railroading and most of the subjects I work with are very small hence the need for something smaller and more accurate, I'm looking for something...

Hi there, I've been watching this thread with great interest and I might be interested in one of these wonderful machines, Is it possible to ship them to Portugal? If so, do you have them available...

Hi there guys, just a quick question, would this design work if everything was reduced by 50% (except for the motors of course)? Would it loose any accuracy? I need a smaller sized machine but I...

Hi there, my name is Nelson Almeida, I live in Portugal and my first contribution to this forum will be a question. I hope I choose the right sub-forum to make it and I'm sorry if this question seems...
