Hi, there is local seller of these machines, he says they are made in China. I can't find any information in google for them. If u know other places where they are sold, please share.

In my country new steel costs 1.4 euro per kg. they buy scrab steel at 0,2-0,3 euro per kg depends on thickness. I asked for discount but they cant make.

There are some T-slot tables for selling near me. What do you think to use it as a frame. size is 2000x4500mm.This is a bit bigger than i need but there isnt other size. Price is 5500 euro. 10 tones...

I thought our country doesnt have big ovens, but actually we have some very large. The nearest is within 100km with size 4000x4000x1000mm. I asked for price...

thanks peeteeng i will re design my construction. i will try to find some1 to do the reliev..

It is for hobby use, after a bit thinking, 0.1mm accuracy through out the whole area would be perfect for me.

Actually I would be happy for 0.01 to 0.02mm accuracy of the machine

Yes in bulgaria, actually 500$ is a lot of money for my country. Almost one average month salary.

Peteeng: interesting design..

Thank you Peteeng, I will read more about braze wielding, I think this will be the easiest. Do I need to do all joints like this or only for tube to tube conection.

Hi routalot, I will use the...

They will machine it for 500$

budget is 10 000 euro but i prefer to make it

I also heard that i can put the frame outside for 1-2 months on rain and sun, that way it will also stress relief a bit.

Hello everyone,
this is going to be my second machine, way bigger than the frist one. I want to see ur opinions about the design.

I dont really like the Z axis, can u check it? both plates are...

This is the old configuration. I made a new housing for the new motor.

Well, I only need the maximum torque at low speed 0-50rpm because I wind flat wire 5x5mm. My nema 34 12nm is not strong enough

Thanks alot for the useful information, I'll be looking for proper servo motor.

I'm thinking for something like 5-6N.m servo 3000rpm with belt 4:1.. so max speed will be 750rpm which is fine for...

My current motor nema 34 12nm, works up to 900rpm. I can stop it with one finger but at this rpm the wire I wind is 0.1-0.2mm and it works fine.

Will the nema 42 work with 900rpm too?, I cant...

I decided to go with stepper motor. Nema 42 closed loop 20N.m.

The reason is because it has better holding torque and easy installation.
If gear down the servo motor to increase the torque I will...

Hi Craig, unfortunately i cannot use gear box because i already made the spindle.

Hi Al_The_Man, the software is DIY i found in a forum, i have the source code so i can edit it. It uses Atmega...

I havent use servos either, So im a bit confused if i buy servo how to make it work with these settings. I see some steppers are 1.2 degree, so if i want to change 1.8 degree to 1.2 degree motor i...

Thank you, Peter. I guess i can check motor temperature once in a while. One more question about the software. I use atmega 8. The software is made for stepper motor 1.8 degree. What option do i need...

Hi, everyone I have a winding machine with nema 34 12nm stepper motor open loop. The machine is used to wind coils with copper wire. I plan to upgrade the motor with stronger one. My working rpm is...

Hi everyone,
I always wanted to make my own cnc machine. First, my idea was to build cnc mill that can cut steel, but after some reading I realized that is too difficult task for me. So I decided to...

we have talked about this ballscrew in private message

I really want to get grounded ballscrews but the Bulgarian Agent from Hiwin told me that C3 Grounded ballscrew (2505)with a single nut costs 800euro per metre (with a nut indcluded and machine ends)...

Ive just talked to Hiwin supplier in Bulgaria and he told me that https://www.hiwin.cz/en/products/ball-screws/rolled-ball-screws/53_standard-flanged-nut-fsc-fsi-acc-din-69051
this is good enough...

Maybe they dont like us (bulgarians) :(

One option for now...

Since I'm using fusion360 free version I can't simulate strength test. It is only in the payed version. Is there any other way to simulate it?

I'll consider buying new ground ballscrews and keep...

Thanks everyone for your comments. So I will buy dmm or delta motors with high PPR. About the ballscrews I will see how my ballscrews will operate and if I'm not satisfied with the result i will...

A little upgrade on the drawins. Added counter weight steel box with 20mm walls, which i will fill with Lead, it will fit around 80k of lead. The working table will be with m16 holes since i dont...
