This forum is still new and may look a bit empty at the moment.
Please don’t hesitate to ask your questions. If you are building a Raw Creative 2.5, planning your build or wondering about parts, setup or assembly, feel free to start a topic.
I will do my best to answer questions and help as much as I can. As more builders join, the forum will grow into a useful place for tips, build discussions and shared experience.

It can be both, depending on which stepper motors you choose. Many Nema 23 stepper motors use a 6.35 mm shaft, but some versions use 8 mm. So it is ...
That is a very good observation, and you are correct. A helical rack does create an axial force component because of the angled tooth geometry. So i...
Yes, helical rack is a very good option, especially for larger machines. It gives smoother motion and better contact than straight rack. The only do...
Here is another low-cost option if you want to get started without ordering steel plates. You can actually cut the Raw Creative 2.5 plates from alum...
Yes, this is an important point, especially for the larger machines. For a large Raw Creative build, I would personally build a strong and stable ta...
Good question. I will try to answer generally, but I also want to be honest and say that I do not have expert-level knowledge in every spindle/VFD/ele...
The 10 mm spacer does not need to be exactly 10 mm. The top plate on the Z-axis is designed so it can handle a small difference in that spacer thick...
A full 2800 mm extrusion is of course the cleanest solution, but the main drawback is cost, shipping and availability. A joined extrusion may be sligh...
Those motor cover side pieces and spacer enclosures are not included in the standard DXF download at the moment. They are part of our finished plate...
I don’t think that will cause any major problems.Using 0.25" plate instead of 6 mm, and 0.125" instead of 3 mm, should be very close. The difference i...
Hi Dave,Yes, aluminium is a much better match for this type of machine than steel.With the correct settings, you can cut a lot of aluminium on a machi...
