Question1:
The print platform appears to be made of Acrylic plastic. If it is Acrylic, the melting point of this type of plastic is lower than typical operating temperature of the extruder. This could be a very serious reliability issue for the user, esp:ecially if he performs machine leveling with the extruder preheated.
Answer:
There is cooling fan in our 3d printer, and machine leveling and extrude preheated are two seperated instructions, not work at the same time, and our 3d printer have passed different lab testing like FCC, CE, and some chinese authority testing lab, no need to worry about the safety.

Question2:
My print platform came with plain color masking tape installed. After printing a sample object, bonding to the tape was so strong it was almost impossible to remove. I had to remove the print platform and hit the object on the side with a small hammer! I have since switched to “blue masking tape” with much better results. Your accessory kit includes plain, not blue masking tape. Which do you recommend?
Answer:
Yes, when temperature is cold, blue masking tape is better. We use plain color masking tape is considering the printing quality, because in Summer, if use the blue masking tape, the printing object may be edge warp.

Question3:
Cura (version 1.3.1) for Mac is very, very buggy and impossible to use. There are many problems. When loading, it tells the operator “A newer version of Cura exists” do you want to load? (I think it’s a big mistake if you select yes). When using Cura, the program gets stuck and does not allow selection of expert mode. Also, you cannot select Support type or Adhesion type. These are a few of the many problems. I find it impossible to use. Is there a new version of Cura.Weedo for Mac?
Answer:
Pls use Cura 1.3.1 version in SD card, the program gets stuck maybe caused by shortage of computer memories, pls try to reload the cura system.
It does not allow expert mode, but you can make all the setting in advanced setting.And in cura you can select support type or adhesion type in advance setting.

Question4:
