  1. Alternative sources for Stepper Driver signals.

    I have, among others, just bought a cheap Chinese router/laser engraver controlled by grbl on an Arduino board. I am in the process of increasing the 320 x 160mm table size mechanically and using...
  2. Re: Can anyone identify my chinese laser controller as I need a circuit diagram.

    Thank you both for taking the trouble to help me.

    I have done some further searching and I am reasonably sure that the MOBO is an RDLC320 as none of the others that I can find are anything like...
  3. Can anyone identify my chinese laser controller as I need a circuit diagram.

    Hi folks,
    I bought my Chinese 50W(?) laser some years ago and must admit to not be being very impressed with the performance of the laser. I reckon that the quoted power, as so many others have...

    Building a positioning visual display.

    I am in the process of building an OSD for my home built CNC machine.

    The circuit utilises CD40110BE up/down/counter/drivers directly driving dual 7 segment displays. The ICs have an up input and...

    Re: Earthing spindle on Yuhuan VFD

    I would not dream of using flexible conduit in the circumstances that you suggest. I do use it to route cabling on non-moving parts but if they were required to flex often, would result in the...

    Earthing spindle on Yuhuan VFD

    Hi folks,
    I am finally getting around to installing my Yuhuan VFD to my chinese, 1.5kW, water cooled spindle.

    I have watched numerable YouTube tutorials on the subject but still feel uneasy with...
  11. Chinese 1.5kW, water cooled spindle and controller.

    First of all, I apologise if I have come to the wrong section in which to make this post.

    I am working on my design for an automatic tool changer that requires the tool holder to be slowly...
  12. Information please on step/direction pulses to stepper motors.

    Hello folks.

    I intend to use a microcontroller to run an on screen digital positioning display (OSD) but need to know something of the nature of the pulses sent to the stepper driver and/or the...
  13. Re: Need info on socket connections for DRO on cheap chinese 5 Axis BOB

    Hello John-100,
    First of all, sincere apologies for not answering sooner. The cause was illness and that the notification went to my spam folder.

    I am somewhat confused at the circuit diagrams. ...
  14. Re: Considering a Chinese imported laser machine with weird plug socket - HELP

    Yes, the machine has been modified and the white socket is a standard British, 13 amp, 3 pin socket (twin and ground). However, I would guess that socket has been added for external equipment to be...

    Hi Folks
    I am rebuilding my home built CNC machine and have now fitted a 1.5 kW spindle motor with a Huanyang Inverter.

    My original BOB was a cheap chinese, 5 Axis version that came with a hand...
