    Hi Amit,

    I tried connecting a vfd to knozz board, j3 connecter. And tried running c program that you sent me earlier.

    But i am not getting pwm out signal on pin number 2 of j3 connector.
    Are you applying a voltage across AnalogVcc and AnalogGnd?

    Could you please tell me which io bit is j3 connector of knozz connected to kflop jp6.?
    KFLOP IO26 (JP6 Pin5) drives the PWM to Analog Circuit which creates the Analog Voltage.

    I am having one problem right now after nozzle started working. Something is wrong with knozz j2 connector. Neg and gnd is connected internally and +12v is also connected with +12v internally.

    And in case of j1 connector its not. heating starts automatically when i give power without any intialisation of knozz c program.

    Which part of knozz board is causing this problem. Is the mosfet of j2 connector.
    The FET switch is connected between the NEG terminal and the GND terminal. Those pins should not be connected internally unless the FET is damaged. The +12V and +12V connections are connected together internally with a copper trace.

    I'm confused on which is not working J1 or J2. How are the connectors wired. I thought it was working. What changed?

    Regards

    Hi tom,

    Thanks for reply.

    J2 connector of knozz is not working.

    It always has 12v output and input. There is no switch working.

    One of our electronic person unplugged heater from j2 connector while it was heating with the m100 p50 command. And plugged multimeter for checking voltage. After that it stopped working.

    Please suggest me some solution.


    Thanks again

    Hi Amit,

    I'm confused. You sent me a private email saying a Relay was connected to the FET Output?

    The Heater should not be unplugged with power on.

    Could the meter leads have shorted?

    If you connected the Relay, did it have a reverse diode across the coil?

    Anyway if you contact Dynomotion Support and pay for shipping we can send a replacement board.

    Regards

    Hi tom,

    Thanks for reply.

    Can you please suggest an alternative option for replacing that mosfet.

    Because shipping and other will be time taking and expensive.

    Anticipating your kind reply.

    Thank you

    Hi Amit,

    The MOSFET is an N-channel Infineon IPD025N06N in a TO252-3 package

    Basically 60V 2.5mIlliohm 90Amp continuous 2.8V gate threshold voltage

    Hi, Tom

    Thanks for your reply.

    Now Mosfet is replaced with a new one. and Its working fine now.

    Still how do i connect spindle on/off/direction switch to knozz board. and on which connector is should connect the spindle direction/on/off wires.

    My nozzle and bed heaters are working now. and spindle is running by using knozz. but direction control and on off switch is not working.

    Anticipating your kind reply.


    Thank You
    AMIT KUMAR

    Regards

    KNozz only has 2 Outputs driven by KFLOP IO26 and IO27. They can be used for either Heaters or Spindle control. But not both at the same time. Here is the IO Table from the KNozz on-line help

    You haven't told us what your spindle needs to control it. Are you switching the main power or maybe a 24V VFD signal at a few milliamps?

    Adding our Konnect board would add 16 more outputs.

    Or you might add a 3rd party relay driver board that can be driven by KFLOP LVTTL IO such as:
    Relay Board: TTL Logic Level Inputs, 2 SPDT 15A Relays - Winford Engineering

    Setup of knozz is done now, everything is working fine now.
