Thanks for help, after ger21 say about backlash I started to search where can it be. And I found it, ball screws support bearings were not fixed correctly , so I fix it and results:...

hello,
I think I found problem, today I will try to fix it and then I will post results.

when measuring with gauge indicator backlash is 0.02mm, so 20um. I bought new ballscrews. Sad, I will need to buy new ones. But that circle milling per two half's, how I can make that circle mills...

Hello,
I have build CNC, when I calibrate it with gauge indicator (10mm lenght, 0.01mm resolution) for example: go 3mm Y or X axis, gauge indicator shows 3.01-3.02mm. then go -3mm, indicator shows...

Hello,
maybe someone can share your experience with CAM software for Solid works? I need CAM for 5 axis CNC, which works inside Solidworks. Solid CAM, as the manufacturer say: "SolidCAM+SOLIDWORKS...

Hi,
maybe someone have any experience with 2DM556 stepper motor driver?

Thank you Mactec54! So if I want that these parameters don't change, I have PD000 make 1 and all saved parameters will be locked?

Thank you!
My spindle:
2) Power:3KW

3) Voltage: 220V

4) Frequency: 300 Hz

5) Speed: 0-18000 R/min

Thank you!!! so I will change PD11 from 0 to 120; PD73 from 0 to 120; but what to do with PD143, I dont know number of poles; What to do with PD144, default setting is 1440, do I have to change it to...

thank you very much! What to do that PD14/15 will be same all time and that was before don't reapeat again? May be to lock parameters? does it helps? I change that parameters, which say seller, now I...

Hello,
I buy 3kw air cooled spindle (300Hz) with VFD. Seller send email:
"If you use this VFD for the spindle motor with 0-300HZ, Please set the parameters of the VFD as our following suggestion...

Thanks, so if my Y axis with z axis is about 90kg, X rail is two SBR 20, so for one bearing is 45kg load.

Thanks to "wizard" for informative answer!
Question: 80kg for X axis SRB 20 support rails is too heavy or not?

Question: 80kg for X axis SRB 20 support rails is too heavy or not?

Thanks, but 6mm thickness profiles is heavy, for example Y axis will be 1.5m long, so it would be about 45kg+ z axis would be about 30kg, so y axis would be 75kg. I use supported linear rails 20mm...

True :) You are community moderator, i believe you have a lot of experience, you see a lot of different cnc machines. What do you think, I will build cnc as in that video from youtube,just y axis...

If steel minimum 6mm, and you use 250x100, this is steel, so what to talk about people who made routers from aluminum profiles, if 6mm steel minimum, so aluminum have to be 300x300mm minimum? :D by...

Thanks for answers. Motor inductance is 5mH, I will use 60V 350W power supply for one motor. Spindle 3kw air cooled. But I have the motors and rails ans screws, so I can't change it now.
So:
*What...

Thanks for answer :) 1600oz is about 12 Nm Holding torque, so if speed increase the real torque decrease; I want to mill hard wood, aluminum and sometimes steel, so if motors would be weaker...

Thanks for all answers! I don't want to make new threat, so I will write in this topic. So: Y axis will be like design #1; cnc size: X axis 1900mm (Ballscrew 2005 and SBR20 from both sides), Y axis...

More info: cnc frame design will be like in that video ( https://www.youtube.com/watch?v=gg2UvbRsLP0 ), so now I'm thinking about Y axis design

Yes, I know that square support rails would be better, but HIWIN is too expensive to me right now :) Ok, thanks, so in first place is design number 1 :) X axis will be 1900mm, Y axis 1300mm and z...

106 views and no answer. Is there someone who can answer to my question: which (1-3) design is most stable and most accurate?

Hello,
I need help, I hope someone can help to me. I thinking which y axis designs to choose, I have 3 options:
1. Ordinary: both rails in one row, example:...

Hello,
I will build X axis 1900 mm, Y axis 1500mm, Z axis 500mm cnc machine. But I can't decide which design to choose. I will use for X axis ball screw and 2 steppermotors for both side of x axis....

:D I feel sorry for you, this your answer show that you have no imagination, sorry, but if you want make a joke, you have to try harder ;) why you post sarcastic amazon link?...

143 views and no help, sorry, but cnc zone is died. May be someone can recommend another forum which is active?

Are there some people people who can help? Or this forum is died?
