flsun i3 lcd panel install pricelist

This was the same problem that I had using the "stock" firmware that was emailed to me (because the SD card was DOA) from FLSun. The Z axis would ignore any sort of limit, be it the prox switch, or a hard limit. However, plugging the prox into the X or Y limit port would work. Sooo... it was the firmware that was at fault.

Now as to the Z height problem, in MatterControl I selected the BCN3D Sigma as my printer since the FLSun wasn"t represented and the BCN3D has dual extruders. Homing (G28), and Auto-Level (G29) work fine, but I had to subtract 2.4mm (your height will vary depending on the prox"s relationship with the nozzles), which I put in the printer profile.

The LCD screen is vital for operating the printer. Should you encounter any kind of trouble, such as a dead screen, corrupted text, or other issues, please refer to the guide below.

First of all, unscrew the LCD screen from the printer frame, remove both M3x10 screw holding it the LCD board in the plastic casing, and remove it from the casing. See if the problem still appears when the LCD is not pressed by the casing.

Firmware updates are necessary to keep your printer up to date. However, the installation of incorrect firmware can lead to letter corruption on the LCD screen. There"s an easy fix, though:

There is a small chance the printer"s LCD screen can glitch out by electrostatic discharge when inserting the SD card. Try to turn the printer off and on again.

This problem usually appears only on user-assembled printers. If your printer"s LCD screen remains blank or displays corrupted symbols after you turn on the printer, there is a chance it is caused by incorrect wiring. Follow these steps to fix the issue.

If you suspect that the LCD ribbon cables connectors are not firmly seated in the slots, disconnect the LCD ribbon cables and check the slots for any bent pins. If there are bent pins, you can use tweezers to fix them. However, be very careful not to break the pin(s) completely.
