Would you share Z_axis_motor_holder model in format like STEP or F3D - I need to redesign this part for my purpose. I have chinese CNC3018-like machine and this part got broken.

ok sir i share the step file

Hi and thanks for the neat design. I'd like to give your design a go but I have a spindle motor with a diameter of 48mm. Do you possibly have a mount for this size or can you please give me the source for that part so I can make one for my motor?

An alternative for me would be to use a flexi extension from my motor to the mount.

I only intend to make PCB's with this so no heavy work required.

i share the source file

very nice design, thank you for share with us.
im assembly one exactly now, you may tell me the bolt list that you use? sorry fo bad english, its not my native language.
one more time, nice job!

sir my english is too bad my mother language is kannada. its ok. i used 5mm bolt with t Nuts

thank you for reply!
i bough the screws and the assembly is ok. m5x10 is ok, but m5x6 is better for me. for the 775 spindle i used m4x30.
aah, one more thing. you can send me the board(table) design? only need this to test your project.

actually i marked by keeping a mdf board and then drilled screwed

Hello. Are the dimensions of the Z car for a 775 engine?

Cnc in pictures uses 9 pcs of aluminum extrusions, your description says 8. Keep that in mind when ordering extrusion
Also 623zz bearing have internal diameter of 3 mm, so do you mind telling how you put 8 mm shaft into 3mm hole?
Nice design but I suggest to print it first and then order the hardware

Thanks for finding wrong i used 608 zz bearing where its mentioned wrong size bearing

thanks for correction. Yes the all extrusion is 9 Nos in design pics but in actual pic i used only 8 nos

Nice design. Maybe the 8mm rods are a little to weak for CNC Mill. Is it possible that you offer the source files to modify it or can you offer different versions? Thank you in advance.

Ok. I will upload the source file

Thank you very much

Neat design!! A couple of questions comes to mind:

-What electronics would you use? And what software?

-I'm guessing the build plate is made of aluminium, do you have the exact size ?

-And lastly, what tool are you planning to use?

I am planning to use ARDUINO Uno with CNC shield. About software i know Inkspace and where can i transfer to g code. About milling and all i have to learn a lot. I am basically a electrical & electronics engineer . I required to make PCB's my milling. The bed is just for design alluminum extrusion can be easily assembled to this design since the freedom to align the rods and fix the Sliding block linear bearings.

Well! I'll be watching this! If it wasn't the fact that I just got my 3D printer, I would build one at the same time as you do!
