Where to buy spindle

[HipoPapi]

Hello again,

I have been quite busy lately with work, but I think I finally know which way I am going with this build and some help would be appreciated.

So far I have the structure and now comes the part where I have to decide what size stepper motors to use and what diameter should my lead screws be as I would like to design the mounts for them.

I assume the stepper motor or servo choice defines the control board choice as well.

A couple of questions:

Can the gantry weight be guestimated ? Yes I am quite lazy to find out the weight of each component :) I know that the spindle motor is 15 kg :)

If yes than what size and torque motors would suite my design? ( I would like it to be fast and strong. Strong enough for wood in comparison )

I assume belt drive is not the best choice in a sub zero environment therefore I have the option of direct drive or Chain and sprocket. What would be the best choice?

I would like to use Mach 3 as the controller and would like to upgrade to 4 axes as soon as I am done with the build. Do you have any suggestions on control boards and the electronics involved?


Here are a couple of pictures of the structure to make things a bit clearer:

Light Grey = 100 x 100 x 3 or 4
Dark Grey = 150 x 100 x 3 or 4
Orange = 10 mm steel plate
White = 20 mm aluminum plate
Blue = ice
Purple = removable module to be replaceable with 4th axes module in future
20mm HIWIN rails an all axes






Any suggestions would be greatly appreciated.

Thanks,
Vass
