SETTING UP KFLOP, KANALOG FOR NEW CNC ROUTER RETROFIT

[TomKerekes]

Hi Noel,

No, but you can connect Konnect to JP4 instead to free Up JP6.

Here is an example using software, 2 Konnect Outputs, and a simple circuit to create an opto Isolated Analog signal. Response rate is not great but adequate for most applications.

Thank you Tom.

I moved the Konnects borards to JP4 and modified the init C program "AddKonnect_Aux0" .

You might copy our KStep/KNozz PWM to analog circuit

i have built this circuit already, i am trying to find out how to configure an output as PWM from JP6, do i need a C program for that?

Hi Noel,

PWM Output Mode for an Axis is not directly supported. A C Program can be used to have the Axis Output directed to a PWM in the mode necessary for your system. See the "Setup Gcode 4 axis PWM signMag.c" example.

Or to just output the GCode S value to a PWM see the SpindlePWM.c example.

I set on tool setup settings the S as "execut/wait/sync" The SpindlePWM.C, the bit 26 box is checked and the state box blinks, so does it mean that the output is working as PWM? now i am trying to figure it out how to set the spindlePWM C values, i entered in the MDI "S3000" and console printed " Spindle Set to 1170.000000 pwm 99", so the console should print the same value as "S value"? I mean how to set the specific values to match the real spindle RPMs.

thanks

Hi Noel,

Is the Var set to 0?

Is the SSO set to 1?

[NOELNOG]

I set the VAR to 1, and console print the S value now.

Is the SSO set to 1?

where is this parameter? i attached the log file after ran two g code programs with different spindle speeds, one is 10,000 and the other 18,000 rpm and it printed ok.

SSO = Spindle Speed Override on the KMotionCNC Screen. See here.

oh ok, yes it is working ok, when i move the slider up and down the console prints all values right away.
now what i noted is the output 26 in aux1 is unchecked, the first time i checked manually to observe the status, but after turn kflop off and turned back on, it appear unchecked, so o i need to add a code in the init program to activate the output 26?

[TomKerekes]

Yes

Hi Tom

question about the Konnect outputs, in the case i connect directly 24v electro valves or solenoids, do i have to add a flywheel diode? I know some relay card have already flywheel diodes installed but maybe not the solenoids or electro valves.
