  1. Re: Problems with synchronising spindle for screwcutting

    I'm trying optocoupler connection. It's NPN encoder to PNP optocoupler. When optocoupler is connected to the controller board, on IO panel, it shows ABZ all green. Is it normal, should it be all red...
  2. Re: Problems with synchronising spindle for screwcutting

    My lathe use servo motor 80ST-M02430 as spindle. I noticed when I enable the spindle motor the interference happens. Not only to the encoder, but sometimes also disconnects the communication between...

    Re: CNC lathe threading cycle G76

    No, currently I'm using the TNGv2 on the planetcnc website. If you have older version that works, please let me know the download link and I can have a try. Thanks.
  5. Re: Problems with synchronising spindle for screwcutting

    I have the same problem which no matter what signal I use, encoder or index, the rpm reading is all over the place. I'm using MK1 software, no debounce or invert encoder signal here. I tried invert...

    CNC lathe threading cycle G76

    Hi, I've noticed the G76 threading cycle command is no longer supported on the TNGv2 software. That's actually a very convenient feature built into the software so that I don't have to use CAM to...

    Re: Construction of a CN lathe

    I'm trying to build a similar CNC lathe like that. The spindle I'm using is 80ST-M02430 750W servo. I'm trying to connect the dir and pul of the servo to the board and use it as A axis on the lathe....

    Re: Mk2 board lathe threading cycle problem

    I found the problem, it seems the wiring only works for common cathode. If it is wired as common anode, the axis will sometimes glitch. Not sure if it is a bug of the old board, found on two of my...

    Mk2 board lathe threading cycle problem

    I encountered a problem while using the G76 Threading Cycle. My test gcode is as follows:
    G0 Z0.0 X 0.0
    G76 P1.5 Z-10 I-0.5 J0.1 K0.3
    M30
    When I ran the program, the software interface did show...

    Re: CNC Lathe encoder Mk2

    Thanks for the reply. I got another question, my spindle to encoder is actually on 2:1 reduction ratio. Does the PPR setting in software be the encoder PPR/2?

    CNC Lathe encoder Mk2

    Hi, I wired the encoder to my lathe using the mk2 board and using the original USB CNC software. The encoder I used is Omorn E6B2-CWZ1X with 2000PPR. I set the same PPR in the setting and index as 1....
  13. Conditions and looping function support for software

    I would like to know if macro commands like GOTO or IF are supported for the original USB CNC Controller software, not the TNG version. Thanks.
