The 1mm height difference you are experiencing, is that from the stock table? I myself had the same problem and the easiest way to eliminate this problem is to take a plywood plate and fix it to the...

The problem with 3d printing (on hobby basis anyway) are that the materials can't be much stiffer than ABS plastic. In a guitar you want it to be as stiff as possible, hence my idea of using...

Rigid tapping is out of the question. One would need a spindle with speed feedback, but even if a 6040 had this option it would be way out of its torque range.

Thread milling might be an option,...

No problem about the imperial... i did the calculations, so i also know the answers in metric. If you stumble upon some short single ones, then let me know :)

@G59: Have you done aluminum with these bits? My concern again being that they are 2 flute and the theory says 1 flute for d=6mm (1/4 inch) endmill for the speeds and feeds the 6040 machine like. But...

Its alcohol. Its really effective cooling. The bit is icecold no matter how long you cut and the aluminum does not get more than handwarm (and that is if you are cheap on the alchol). Usual...

Yeah of course, magnets :)

My CNC is located under an exhaust fan from the rooms old purpose as a painting cabine. The purpose of the extraction system is not to went out the fumes, it is extract...

admittedly it have been a while since i played around with FzWizard, since the speeds and feeds i use have worked quit well. But i think to remember that according to FzWizzard that 2 flute was not...

@G59: you are right, but i knew that this was what Ian was talking about (I am studying mechanical engineering :) ) . But i could not find anything with 1 flute, that was shorter than 17mm on ebay,...

Thats a nice idea. But they would have to be easily interchangeable, so they would need some kind of quick attachment system. Maybe some day if i have time :)

I mostly do aluminum so dust isn't...

I was thinking about making one consisting of 3 planks og mahogny. they would be cut out, so when glued together, it would be hollow inside. The feature here being a light guitar, but with the...

So how was the machine? We are quit excited to hear :)

Hey donminion.

You need to calculate your speeds and feeds on the basis of your bit diameter and how many flute you have on it. Try to imagine that we are going into super slow motion and watch...

Nice work. That seems to work quit nicely. I will have to make one for my machine.

Just an idea: How about making one more spacer with the shape of a ring. The inner diameter equal to the intake...

Man that looks nice. I have a dream about making my own guitar on my 6040 one day. A Fender Stratocaster body will fit perfectly in the machine :)

Hi Ian.

i use these carbide bits from china:

I sometimes go through a 20mm aluminum plate, so thats why it is so long. I did...

Okay i have had this machine for 1½ year and i really love it. Sure there has been some small bumps on the road, but it is all forgotten as soon as i see aluminum chips flying.
...

Sorry, now i actually remembered why i didn't opt for the sherline. It has threaded leadscrews for motion. This means that there are a little "play" or backlash. when going from one direction to...

Congratulations on your buy. Try to source ebay, there might be something there. I was also looking at the sherline, but the working area was to small and the material removal rate are much higher on...

Here are one similar to mine:

For speeds and feeds calculation check this:

It calculates...

Nice that it was a quick fix. Even though the problem rates on these machines have come down they still can run from the fact that they are chinese... but you still can't beat the value for money on...

I can testify to the Gecko drivers. I am a mechatronic engineer and i use them in all projects requiring steppers. I was ready to buy the G540 card to replace the chinese stepper drivers and...

Btw i also mostly do climb-milling, but it dosent matter that much, since you will have material on both sides of the bit. And finish passes are required if you want a nice surface and precision in...

Its weird but i sometimes face the same problem on my 6040. Sometimes theres just a spot on your toolpath that makes it resonant although nothing as severe as you describe. I do have som tips.
...

I had a similar problem with that exact model. But mine did not shut down, mine triggerede the HFI-relay and shut of the power for that part of my building. It was a pain in the ass to find out what...

First of you have to learn CAD. If you don't master CAD you won't be able to learn the CAM part. It can be a tough learning curve, depending on how computer savy you are. If you want to play it save,...

You probably could do it if you take it slow and the model is not more than 20-30 cm of height. I have the 4 axis and it is a bit flimsey. This machine would not be ideal for a production run of such...

Thanks for your reply. I have actually just ordered one from robotkit, but if they don't work i will try yours. I will of course brief you on the motors from robotkit.

Hej Robbie, thanks for the link. They could interesting depending on the price. Do you have any information regarding their prices?

I have made this with my 6040Z-S80 from carvingcnc.com. Its made out of one solid 10 mm aluminum sheet. I have not tried anything thicker than a 20mm aluminum sheet, but it might be...
