Have your say about this chinese cnc milling machine

[Boyan Silyavski]

Hi Cousin, thanks for you reply. I contacted a guy in Croatia who has already the same machine from same manufacturer and he is satisfied with the performance and he say that is working with 0.01 accuracy.
Do you thing this mill is better deal http://polymeta.bg/?page=newmach&cat=46&pid=185
Price is almost same, but i noticed that this is 800kg and the chinese one is 1300 which make me thing the chinese one is stiffer. You wanna say that if i decide to buy the chinese one to contact your agent about the transport?

This one has slower spindle speed. Maybe have to speak with them about that. In reality you could add with a bracket Watercooled 3kw spindle / 500 euro with VFD/ or smaller and cover it all. Ene 0.8kw will be ideal. High speeds you will need for the small bits. Many people do that, as its the cheapest solution. No toolchanger in this scenario. Price is without VAT, note that.



The agent could find who makes that really, may be find it near her,etc. It really makes a difference when contacting Chinese if an agent there does that.. And you dont have a wait a week when you need to know sth. You pay her a fee but you are sure that the people you buy are real and that you buy at good price. I can put you into a contact with her.

Its ok, let me have her contact.

Its ok, let me have her contact.

Once you decide 100% on the Chinese machine, and have the money and are ready to buy, i will contact her then. She is busy woman as she is an agent also for big factory In China and here Spain, where my wife works and she knows her personally from work and from China.

Hi there Boyan how are you?
I have a Chinese 3 axis cnc6040z with the black box I bought a while ago,I have removed the motion controller drive board that came with the machine it has no proper documentation it is in Chinese and it is crap, comes with USB CNC software v2.10 with activation key on cd including driver file.I would like to run Mach3 or 4 and would like to know if the NX-USB 4 axis USB motion card is a full plug and play type no extra cards needed and also on the mach3 plugin site they have a plugin driver,would this plugin be good for my cnc6040 machine or do i need to do other things?? sorry for all the questions, Im a newbie and need information ? Thank you

!sorry if it is posted in the wrong place

My advice is DDCSV1 offline controller for your machine. No MAch3 and stuff.No stupid USB connection. No computers. Solid working as a rock.

Or go the UCCNC way, board and software, which i have not tried but others say is good and better than Mach3

If you insist on MACH3/4 buy a reputable board from a reputable seller with a well tested plugin that works well. PMDX and similar. I will not buy a chinese board with a chinese plugin that 100% is not working properly or has a flaw.

There is also the original USB CNC from Germany, that all Chinese copied. It also is a good option for your machine.

In that order.

It would not hurt to see what are your motor drives, if they are not integrated in your original board so now you need some cheap new drives too when changing to a new board. And a PSU upgrade may be? Not sure, check that. Maybe make a thread about that?

Hi there thanks Boyan, I think I will go with pmdx-422 board and Mach4
But would like to ask is that the only board I need
To run 4 axis on my 6040 or do I need to get extra boards
Because I would like for simplicity one board does all??
Please help

It has no sense to use 6040 with expensive controllers.

LINUX CNC runs RT , it is much more reliable than any USB solution...


Professional solution for ca 250 EUR:
Galil
MYRIO - student (national instrument)
...


I am proposing to use MYRIO, + Labview (5 axis driver is open free...)

Depends on your goal:
- do you wish to start machining or
- do you wish to learn how to do CNC

ok thank you for the reply ,I dont want to spend a fortune on this machine just want to get it moving with mach 4 and start milling Aluminium and pcb blanks and plastics ect, the motors that come with the machine are 57HD5401-14S 1.8 deg 3.0A N1605 : I just want to know if the PMDX controller i mentioned is good for this machine with standard motors and or the Nema 23 Bipolar (Holding Torque 3Nm) (425oz.in) 4.2A 57x57x114mm 4 Wires better for cnc6040 with the PMDX to move fast and do I need a switching psu of 36v~40vdc for the Nema 23 or can I use the same 24v dc that is in the blackbox already?

Hi,there Boyan i would like to know if this AKZ250 Mach3 USB Motion Card can be connected with the Nowforever VFD 400HZ i have and drive the 3x (57HD5401-14S) stepper motors that came with machine or do I need 3 similar to these DM542A stepping stepper motor drivers per motor and if I can go with this setup what stepper motor drivers would be best for running the 3A ones I have? thank you

***[The Stepper Motor Info is:
Model: 57HD5401-14S
1.8 deg 6.6v 3.0A N1605
17kg/cm=1.6671305 Nm]

You need separate drives for the motor. About the card, maybe read the manual: http://cncmanual.com/mach3-usb-motio...lation-manual/

I am not very excited from Chinese motion control and mach3 combo

Why not go the EU way and http://cncdrive.com/UCCNC.html ? Good board and software, support, etc. Combine it with cheap drives and voilaa
