V400 FAQ

1.What type of motherboard is used in V400?

The V400 uses the MKS nano v2.1 motherboard with klipper firmware.

2.What is the type of driver used in the V400 and what is the range of current passing through it?

V400 using 2226 driver with 1.5-2A current.

3.What is the belt type and length and width of the V400?

4.What are the nozzle types and available nozzle models for the V400?

The nozzle used in V400 is our own designed high melt nozzle, the profile size can be adapted to the crater nozzle, but the printing speed needs to be reduced when printing. v400 supports 0.2/0.3/0.5/0.6/0.8 caliber nozzle, but the configuration parameters in cura4.13 should be modified simultaneously.

5.What is the maximum temperature that the nozzle and hot bed of V400 can reach?

The nozzle can reach up to 300 degrees and the hot bed can reach up to 110 degrees.

6.How many ways are there to print on the V400? What are they?

There are 2 types of printing methods, namely U-disk printing and WEB-side printing

7.What kinds of print model file formats does the V400 support? What are they?

There are two formats, gcode format and ufp format (ufp format can show the model thumbnail).

8.What are the hot-side fan and motherboard fan models for the V400?

The hot-side cooling fan is 4010, the hot-side turbo fan is 4510, and the motherboard cooling fan is 6015.

9.Are the V400's heating rod and temperature sensor the same as the SR's?

The V400 heating rod and temperature sensor use a longer wire than the SR heating rod and temperature sensor, and the V400 heating rod has a power of 60W, which heats up faster and warms up more.

10.How to check the LOGO/LED light of V400 is not on?

Open the upper case of the machine, exchange the LOGO and LED jacks on the adapter board in the state of disconnection, turn on the machine and turn on the LOGO/LED lights to see if they can light up and down normally. To determine whether the LOGO / LED light problems or adapter board problems.

11.V400 machine can't connect to WiFi, what should I do?

1.After entering the wrong password, the network cannot be found. After reboot, you can delete and re-enter the password to connect.
2.It shows connected, but there is no ip address. The interface is: eth0 (network cable connection), you need to reboot the system to wlan0 (wireless connection), wait a while and the ip will appear.
3.There is an ip address, but the web side is inaccessible and shows an error. This indicates that the ip address has changed and you need to reboot to show the new ip.

Note: The connection must be made under the same LAN, after the PAD is successfully connected to WIFI, it will always be the same IP as long as the WIFI is constantly on.

12.What should I do if the nozzle hits the hot bed when the V400 is descending?

1.It may be caused by incorrect leveling steps, please re-level it.
2.It is possible that the configuration file is modified or damaged, please replace the original configuration file.

13.How to adjust the nozzle scraping model when printing?

1.Reduce the extrusion flow by ten percent
2.Replace the Gyroid Infill Pattern
3.Properly reduce the printing (idle) speed

14.How to adjust the model does not stick to the hot bed?

1.Adjust Z0. If Z0 is too high, the model will not stick to the hot bed, and if Z0 is too low, the model will warp. (If the first layer has excess extrusion need to reduce the starting layer flow)

2.Properly increase the first layer printing temperature and hot bed temperature

3.Add skirt to the model
4.Apply solid glue to the platform

15.How to adjust the V400 machine with uneven adjustment?

1.First of all, make sure that the machine is installed firmly and without skew.
2.Make sure the order of leveling is correct
3.No impurities under the pei board
4.No obvious resistance when sliding the slider, and keep the same tension of the three belts.

16.What should I do if the klipper has stopped on the V400pad page?

Whether this happens before or during printing, please open the web side of the machine on the computer page after connecting to WiFi to view the detailed error message. And send the error message to our after-sales service to solve it for you.
