I am talking about a moving saw blade, just like the moving blade in the large sheet cutting machines.
Thanks.

Hi guys,
I have built my first CNC machine 4 years ago and hopefully it still works.

Now what I am wondering about is if I could be able to built a large sheet cutting machine for melamine and...

Hi I need to make a brand heat stamp on brass using a V bit 20 degrees bit with 0,2mm tip. I am going to clear with a larger tool (ie. 3mm end mill 2 flutes) and the rest with the V bit.
Could you...

Hi guys, I am back to this thread in order to suggest/ask for another solution:

What if just use a downcut bit 1.5mm in order to carve the plywood? It would not be a 'V' carve but a U groove. ...

Sorry cannot "catch" you.

Router is rotating normally using M3 command
and it follows "climb" move.

Do you mean I need to move it "conventional"?

Feed rate is 2500mm/min in all 3 videos.

Router bit manufacturer suggests 5mm/min at 18000 RPM, so I will try at 9000 RPM and upload new video.

Ok, I will upload also a video with RPM = 18000

Hi again,
here are three videos of same feed rate but diferrent RPM (12000, 11500, 11000 respectively)
The router bit was very easy to touch right after each process.
I haven't tried to lower...

I cannot say that it squeals or screams but also I cannot withstand the noise for all the cutting process without using ear protection stuff.
Are you guys able to withstand the cutting noise when...

Thanks guys, hopefully the spindle is water cooled, so thanks to all of you for helping me.

Generally, sometimes I cannot determine the correct RPM according to feed rate. Let me explain:
I try...

Hi guys,
I have the chinese spindle 2.2kw and I would like to ask if I can make cuts at 10000RPM in soft wood because my machine can't go faster than 3000mm/min so I run it at 2600mm/min and I set...

Hi, what is the difference between the two drivers below?

DM556D Digital Stepper Motor Driver 50VDC/5.6A High Performance for CNC Router | eBay
Stepper Motor Driver Stepper Motor | Stepper Motor...

Regarding performance, I do not need cutting speeds more than 3.5m/min. I do not care about rapid speed. I do not have any component yet, but I am willing to built it more rigid than my first machine...

Hi guys,
I am to build a CNC from aluminium with dimensions 2mX1.2m and I need to include an additional axis for rotary motion/lathe. Motion parts will be ballscrews, linear bearings and linear...

Thanks, the problem is how is it possible to glue paper on plywood without wrinkles?

Hi guys, I am willing to produce quick pieces of thin plywood (4mm) like this in the link which are given after each baptism. It seems that they have a sticker or are painted with color. I am...

Hi friend, yes I know it is a lathe for wood. So, I am glad to hear that it can be done. Awesome.
Thanks

Hi guys,
I have build a cnc and I operate it for 1,5 year so far and always I had the word 'lathe' in my mind, although I have never used a lathe and what is more, have never used a lathe in...

Really? And I discovered it after 1.5 year of work.
Thanks for the info.

Hi guys, I need some help regarding the motors,

When I turn them on, I can listen a big 'duk', which actually means that current is going through motors but I also notice that all axises move a...

Hi Gerry, what is the sealer? And what is its job?

Thank you for your suggestions, the plywood is birch

Hi guys, I have used a chinese 30 degrees V carve bit in order to quick engrave some 1.2mm grooves to a 4mm plywood in one pass but the result is not clean so I need to make a 2nd pass 0.1mm deep in...

Hi again guys, I am posting here because the question is strongly related to the same working piece and wood (linden).

I am trying to make some vertical 6.35mm holes, 26mm deep (please check the...

Hi guys,
this weekend, I tried the following methods with the same bit but a new(chinese) one 2 spiral 3.175mm diameter, 20mm length of cut, 24mm stickout:

1) Conventional rough cut the slots...

Dear mmoe friend,
I feel bad for making you get into this trouble and very thanks for your time to give me understand the situation with the cutting approach.
Only tests will tell if it makes any...

Also, in post #34, do you guys know why are the grooves there and not in both sides? Is it the conventional method that push the bit into the material and get this result?

Yes I measured the deflection by applying force with my 1,2,3,4 fingers and one hand. It is described in my post #20. However, I am not sure if this is in the right way to do so, but it is very...

What I can think of the parts' size being varied from part to part is the grain in material. Maybe the grain in some places is tougher and the chinese bit or z axis deflects more. I have cut 60 same...
