Does anyone know how well priced the package is? Since I already have some of the parts I think it will be cheaper to buy them separately.

You could grab the parts listing at
http://www.vicious1.com/product/mostly-printed-cnc-parts-bundle/
and visit McMaster Carr
and collect numbers for almost of them.
A good bit of mind numbing work, though.
You can certainly get it cheaper, but how much is your time worth? You don’t buy the bundle for the price savings, but for the convenience.
The price isn’t terrible but you certainly can do it cheaper. The most expensive parts are the bearings. Like Taylor mentioned, it has to do mostly with time. I bought all my hardware from BoltDepot and my bearings from RobotDigg. Just be sure you use the higher torque models of Nema17
Whether you can get them cheaper separately depends on how many sources there are. Sometimes shipping for many different orders puts your cost over the kit cost.
Beware of cheap bearings, the will rust
@Ariel_Yahni_UniKpty igus iglidur bearings are cheap
I’ve seen a couple printers with this type of carriage system but can’t remember what they are called can you guys help? Just wanting to review a few printers that utilize this style.
Not sure there’s a specific name. It’s just a Cartesian setup with 2 motors on the X & Y axis wired in parallel.
Corexy
This is not a corexy configuration
I was also wondering what’s it called. Also what are the benefits over curexy? I could guess but I’d rather someone that knows
It’s much easier to build/assemble than a corexy, and it’s much easier to make modular (change axis lengths, tool heads, etc)
@Taylor_Landry ok so what’s the downside?
@Taylor_Landry u are correct. I was responding to another post. This is the same setup as Ultimaker but with 4 steppers
Eh, not really. The Ultimaker gantry system is different too. The motors on this setup are mounted on the carriages for each axis. Also, there are motors on each side of the axis.
@Taylor_Landry yes but the placement of the motors is not much revelation. The cross gantry style can be done in different ways.
It actually does play a significant role in the kinematics. The motors being mounted on the carriage adds a lot of weight. One of the main positives for the Ultimaker gantry is how light the carriage is. Less weight/mass means you can accelerate and decelerate quicker, and with less chance of backlash. One of the negatives is that you’re limited in the size of the x/y without dealing with the racking that can occur. With this CNC design, and with a motor in each side of the axis, you don’t have to worry about that racking, but you can’t move nearly as quickly.
@Taylor_Landry agree. Nevertheless we are talking about the placement and gantry design. Each gantry design has its pro and cons. Ones are suited for speed others for rigidity and so on
