Hi Tom,

How to adjust the speed of G0 in KMotionCNC? in some cases, I need to set the speed of G0, to 25% of maximum it's speed. I use KFLOP and Kanalog to control my old CNC Lathe. 

Thank you for your help,

Asmec,

You can setup a rapid override with:

SetRapidFRO (x);

Where x is % of full rapid rate, IE:

SetRapidFRO (.5); //50%

Hi Asmec,

There is a Rapid Rate Over Ride slider on the KMotionCNC Screen for this purpose.  You might reduce it to 0.25.  See:
http://dynomotion.com/Help/ KMotionCNC/KMotionCNC.htm# Feed_Rate_Override

Otherwise Rapid Rates are set in KFLOP with the motion profile parameters Velocity, Aeccleration, and Jerk.  See:
http://www.dynomotion.com/ wiki/index.php?title=Main_ Page#Velocity.2C_Acceleration. 2C_and_Jerk

Hi

if you can reduce the speed of the G0 command, it would lose its meaning like command of maximun feedrate 

Use G1 with more feedrate, if you need to go down de speed of G0 edit the config c file of the machine

regards (and excuse my english)

HI Asmec,

   SetRapidFRO (.5); //50%

   This needs to go into your main loop.

    I use a pannel switch with 4 positions and kanalog analog input for rapid over ride 0% 5% 50% 100%, resistors set the voltage at each position.

{

switchrro=KANALOG_CONVERT_ADC_ TO_VOLTS(ADC(3));

if (switchrro<1.) SetRapidFRO (0.);  //0%

if (switchrro>1. && switchrro<5.) SetRapidFRO (.05); //5%

if (switchrro>5. && switchrro<8.) SetRapidFRO (0.5); //50%

if (switchrro>8.) SetRapidFRO (1.); //100%

}

If the voltage on the kanalog analog input is  less than 1 then SetRapidFRO (0.);  //0%

If the voltage on the kanalog analog input is  more than 1 AND less than 5 then SetRapidFRO (0.);  //0% 

and so on

You could do this many different ways, but this allows me to have 4 rapid over ride switch positions and only use one board input.

Hi Andrew,

Thanks for reply, but where I have to put this : SetRapidFRO(x);

Is in the init file?
Sorry, Im beginner for doing C programming.
Let me test..

Thank you,

Asmec

Hi Asmec,

Change the Radio button to "rapid" to change the Rapid Rate Override for G0 Rapid commands.

KFLOP C Programs can change the RRO by sending these commands:

#define PC_COMM_SET_RRO 54 // Persist+1 is the RRO (Rapid Rate Override) as a float
#define PC_COMM_SET_RRO_INC 55 // Persist+1 is RRO (Rapid Rate Override) the factor to change it as float

See the KflopToKMotionCNCFunctions.c example

Hi Tom,

Thank you for devices,
I did to set the speed from the slider on KmotionCnc. It worked on G1, G2 and G3, but it didn't work on G0.
I'd like to add external selector'switch for select the speed of G0 to 10%, 50% and 100%.

Thanks again for all your help.

Regards,

Asmec
