Hi Andy,

Congrats for your all great work here. Cherry Pi III and PrntQB versions seems to be perfect.

I am a bit indecisive about building Delta or Corexy type 3D printer, but I think I will go for a Corexy and it will be your design. So I will be actively asking for your help in this topic, as I am a newbie in this environment. I hope everyone gets use of your contribution here. Thank you again!

I currently have 5 stepper motors, an LCD screen and five pololu A4988 stepper drivers. I will complete the rest.

1. Which controller board would you suggest? I am planning to get Azteeg X5, is this controller suitable to PrintQB?

Any controller that supports Marlin with core xy kinematics would be fine. Make sure your drivers and LCD are compatible though

2. I saw in one of your posts, that you will change the Z movement just as in the Cherry Pi III with mini V wheels. I am not sure if this was the case. Should I wait for the PrntQB V3, when do you plan to announce the new version? If there is no such case, where can I get Z lead screw nut you use for PrntQB V2?

PrntQB V3 is on a back burner as I have been inundated with orders for my Cherry Pi range (11 built so far)

3. Is any 20x20 aluminium extrusions suitable for your design?

Any 2020 should be fine

4. Is there any advantage of using aluminium rods instead of steel rods? Should they be solid or empty-inside rods?

Any rigid rod or tube will be fine as long as the OD is compatible with the Igus plastic bearings

5. Is it probable to see stretch issue on fishing line, which may cause bad calibration in my opinion.

Spectra line doesn't stretch. It's not a monofilament nylon line it's a braided dacron

I know so many questions here :) They may sound ridiculous for some of you, but I am inexperienced in this area.

I hope you will help. Thanks in advance.

Good luck
