Very nice CNC router. It looks very professionally built, in fact it is so good you probably should make kits and sell them.
Was the router really dancing to the tune of the music?
-
Thank you for your reply!
If not a secret, you are using bearings of the axes X and Y?
I am very impressed with your machine, here in Russia I have not seen such a mechanics. Great.

Hello
What positional accuracy do you have on your machine.
I understand submission of the axes X and Y through your chain?

@eugnret can you make a video from your new maschine, please?

Thank you, it took a lot of thought to design it.
LOL, it does look like it's moving to the tune, but it was just a coincidence

It's not a secret - I'm using skate bearings. If you read the comments in my other videos, you will find more answers re. linear motion and drivers on this 1st table.
I've almost finished my 3rd table with a work area of 2440x1220mm. I have used the same bearing setup, but am trying out T5 belt as I couldn't get enough chain. I'm hoping the belt will work well.....I'll post some vids when it's running.

My accuracy is no worse than if I used rack & pinion or ball screws. If anything, it is better, as there is no backlash when using chain.
The repeatability is perfect. If I machine a sheet of HDPE in 3 passes, you cannot see any of the passes, it looks like it was done in one go.

Please do not email me asking for plans. I said I will think about it, and I will.
I have hundreds of hours invested in these drawings. IF I do decide to release them, they will be sold, not emailed for free.

OK, I'll think about it. I will need a few days to clean them up so everyone will understand them. I have all the drawings as well as a list of materials.
This machine was designed around 100x50mm (4"x2") cold rolled rectangle tube for the rails. If you can source this locally, you should be able to build it.The table can be built out of anything you like, as long as it's braced correctly.

Check out my other vids & read the comments. I've answered some questions re. stepper size, driver, etc.
