Product Identification / Warranty / Service Policy

~ LLC had changed our PRODUCT CODES for extending the coverage ~


1. For laser cutting machine such as LCM / LCD / LCR / LCG (Group A) and LCW / LCU / LCK / LCI (Group B), LLC does not continue to offer them under OLD MODEL NAME. What will we do next ?

  • a. For LCM / LCD / LCR / LCG (Group A), the basic reason of discontinuing to produce is the motion axes in these models needed to be replaced by ball-screw axes for most reliable end-to-end accuracy of big size object in defined working area. LLC now offers CSH series to catch up with the original needs for LCM, LCR and LCG, and CSE series for LCD.
  • b. For LCW / LCU / LCK / LCI (Group B), they are all of smaller size machines with flying-optic configuration, and we were convinced that time-belt based rail is good enough for most of the applications. Therefore, LLC slightly modified and renamed LCW, LCU, LCK and LCI to CBF-130090CBF-155105, CBF-100070 and CBF-060060 respectively.
    Moreover, LLC reserved the possibilities of offering models of other size to quantity order of ATCBF-130090 from customers.

2. For laser engraving machine such as LEW / LEE /LEN (Group C), E96 / E64 (Group D) and LEQ ,LLC does not continue to offer them under OLD MODEL NAME. What will we do next ?

  • a. For LEW / LEE /LEN (Group C), LLC slightly modified and renamed LEW, LEE and LEN to EBF-130090, EBF-090060 and EBF-060045 respectively.
  • b. For E96 / E64 (Group D), LLC reserved the possibilities of doing slight modification and offering lowest prices to quantity order of ATEBF-090060 and ATEBF-040030 from customers.
  • c. For LEQ, a large size CO2 laser engraver, we determined that long axes of ball-screw will do much better works than long time-belt-based axes, since the configuration is about to put a heavy CO2 laser in the moving gantry to avoid beam divergence becoming not workable after laser delivering long distance. Based on above determination, LLC had released EDH-130090 and earned the buying and interest from customers of several different industries in 2017. LLC plans to enlarge the size of EDH to get machines of working area up to size of LEQ. And we hope to meet the valuable market needs for large size CO2 laser cutting and engraving machine.

We aimed at Laser Welding Machines with below listed configurations.

Ball screw lubrication is important for its life and performance. The best lubrication is light oil applied directly into the ball nut at various locations along the length of the screw. Light spindle oil or light way lube is recommended. Grease can also be used for ball screw lubrication because it doesn’t entail complicated delivery methods, and it requires less frequent re-lubrication intervals.

  • Use software to restore defaults

a.Open MDI window: Viewà Show MDI Window(M)

b.Key in”$***” then press ENTERà Reboot after a few seconds

This command clears all data of the controller

c.Key in “$” then press ENTER

This command is to load data into the controller from flash


  • Use hardware to restore defaults

DIP SWITCH 1 the same as $*** command

DIP SWITCH 7 the same as $ command
