Thank you for your comments. Changes that's been made since last time:
- I've changed the tube offset to the motors to more rigid parts.
- Added a plate on top of Z for a motor mount
- All sensors, 3x inductive and 6 micro switches has been added to the CAD to ensure that no clashes will appear late on. This also ment 4-5 extra small pieces for the sensor to activate against.
- Made a groove in the spindle plate making it 6 mm closer to the X-axis. Lowering the moment arm.
- Went through every cad file again to make sure there's no clashes, no missing holes or wrong dimensions.
It's very difficult to predict the forces in the supports to the leadscrew but i will try to ensure that that does not happen.
There will be two layers of MDF/Plywood (hopefully vacuum table) that will cover most of the angle brackets on the bottom so i dont belive that will be a problem.
I've also ordered all extrusions, most of the screws, 30 kg's of stock aluminium and some mounts. Also asked for quotations for watercutting some plates (green in picture).
Also managed to make a few drawings so I hope to manufacture the first parts this weekend.
The "real" manufacturing will begin late next week i hope. I will keep you updated with pictures or something...
Budget will most likely be exceeded, now looking more towards the $4000 mark.
So far the budget looks like this:
- Extrusions, raw aluminium, screws, waterjet cutting -
$1300
- Motors, drivers, breakout boards, sensors, cables -
$800
- Spindle, vfd, collets + some extras -
$500
- Ball screws, nema mounts, holders, linear rails -
$1200
A bit more expensive but I believe it's worth making it right the first time.
I'll try to update as much as I can, using this sort of like a log of the build for myself.
