Hello again! As I have told you before I have started with my CNC project from zero thanks to the tips you have given me. I thought of making a bigger CNC, use it to mill wood, plastic and aluminum, and later I want to buy a small mill and change it so that I can build mould in aluminum and if possible metal.
This time I am bothering you because this week I am going to buy the components from China and I want to make sure that I am buying them correctly, and I imagine this happens to all of us when we build a CNC for the first time. I have a couple of questions regarding the hgr15 for the x axis, maybe they will work or will I need a hgr20?
This is what I have thought for the CNC:
Axis X
2pcs RM1610-1500mm Full length 10 pitch with ballnuts and end machined.98 usd
2pcs HGR15 -L1500mm Linear Motion Guide Rail with 4pcs HGH15 Narrow linear carriages 200usd
Axis Y
1pcs RM1610-1200mm Full length 10 pitch with ballnut and end machined.45 usd
2pcs HGR15 L1200mm Linear Motion Guideway with 4pcs HGH15 Narrow linear carriages 176 usd
Axiz Z
1pcs RM1605-350mm Full length 5 pitch with ballnut and end machined. 26 usd
2pcs HGR15 L=350mm rail with 4pcs (HGH15 Narrow linear carriages)108 usd

Motors
5PCS Nema 23 stepper motor 425oz-in,3A,2ph,1.8° CNC Engrave 241uss
Timming Belts?
Witch timing belts and pulleys do you recommend?
Drivers and supply power?
I have the same problem as before, I believe that you can help me with this. I have researched on these products, what do you think? Is it an analogic driver convenient or a digital one?
