Welcome!!

Project :: Low Cost CNC
Project Description :: This project start because i already sold my old CNC and need to make more space to my room. For this machine i will make it to do my hobby such as cutting acrylic , wood ,some thin aluminum or some PC side panel and i will make it as my coffee table.
Project By :: iD2

Final design (9th revise) ::

Specification ::
- X-Axis --> Working area 700mm
- Y-Axis --> Working area 500mm
- Z-Axis --> Working area 150mm

- X-Axis --> Using SBR Rail ,Dual ballscrew and drive
- Y-Axis --> Using SBR Rail
- Z-Axis --> Using Linear guide

- Overall dimension 1000x860mmx550mm

Before get my final design this my

Z-Axis design ::


Y-Axis design ::


Machine by using Linear guide ::


1st revise by using SBR Rail ::


8th revise by using SBR Rail ::

Just brought some parts and other are coming.

Any of the designs should work pretty well. Take care to place the Z so that you can get to the spoil board. Looks a little high. Pictures of parts are looking good. Good luck with it and I will stay tuned.

Thank you for your recommend.

The motors for x axis are mounted on an L plate (if you know what I mean), only supported on one end.
This introduces the risk of the plate bending under load, resulting in an s-shaped ball screw or at least extra stress on the balls-screw contact area.
Better stiffen that up some how!

[LeeWay]

Right.
I think using a thicker plate than what is shown will handle that.

[iD2]

Thank for your recomend. I forgot to update my last design that already fixed that issued.

Some shields for the screws and rails will be a good idea

Yes , i'll do it both shields and dust shoe.

Aluminum profile already arrive.

[LeeWay]

Then let the fun begin.

Update my lastest specification ::

Specification ::
- X-Axis --> Working area 700mm
- Y-Axis --> Working area 520mm
- Z-Axis --> Working area 120mm

- X-Axis --> Using SBR Rail ,Dual ballscrew and drive
- Y-Axis --> Using SBR Rail
- Z-Axis --> Using Linear guide

- Overall dimension 1000x860mmx550mm

Then let the fun begin.

Just got Water cooled spindle + Inverter + Spindle clamp. So today i do wiring and add Potentiometer to Inverter and then test them to make sure everything work fine and correct wiring.

Item arrive ::




Unpack the package


Start wiring ::










Note :: For single phase power use “R” and “T” but for Three phase power use “R” and “S” , or “S” and “T” , both will work fine.

After finish wiring then test run ::







Note :: Before start run it VFD need to parameter setting.

- PD005 = 400 (Hz)

- PD004 = 400 (hz)

- PD003 = 400 (hz)

- PD008 = 220 (220volt)

- PD072 = 400 (hz)

- PD144 = 3000

This parameter need to set up before start run spindle. Other parameter see document.

After test , It work correctly and everything good so next i need to add potentionmeter to font panel of inverter , it already have socket for putting potentionmeter into it.

Done !!! lol

Video test here ::

Looking good. I really liked your last design. Very clean.
Have fun!

Now electronic kit just arrive and then i will go to wiring and test run stepper motor first and then i will go to drill and tap aluminum and aluminum profile , finally start assembly the machine.

[iD2]

After long time not update , just busy and have something to do. OK let's see some update progress and i think i will finish my machine not over 2 week.

Tap aluminum profile ::






Mark drill & tap position of Z-Axis :: This can do 2 way, 1st like picture below , 2nd print my design as scale print but i choose 1st way.

Didn't see it in the thread, what size SBR rails are you using for the X & Y?
