Re: Snap Amp Noise affecting USB connection

Hi AZ, It turns out that the K flop must be resetting as I have a flashing led running in a C program that shuts off when the disconnect happens. During the last test it ran about an hour with the motor running at about 10% FRO on a G code program. So that would indicate it is not a USB issue but ra...

Re: Resurrecting an old project

Hi Art, If you compile/test your program in KMotion.exe first it should indicate which line has a problem and what the error is. #1 - some statements don't have a semicolon at the end #2 - a Move function needs 2 parameters separated by a comma #3 - the code to do the z homing should be inside the '...

Re: C program stops when G code finishes

Hi AZ,

M2 causes the Program Stop and automatically turns off the Spindle by calling the M5 Action which you have set to use Thread #3.

Re: Snap Amp Noise affecting USB connection

Hi AZ, Regarding noise/disconnects. You might see here . Can you describe/diagram your grounding and shielding? Are your supplies isolated? What current are you running the Steppers at? Can you tell is KFLOP is being reset or is only the PC disconnecting the USB? You might turn off an LED that will ...

Re: C program stops when G code finishes

Hi AZ, What Thread is the C Program Configured to run in? It should normally be Thread #1 as it is the only Thread not stopped on EStop. Do you have any other Action configured to run in that Thread? Running a C Program in a Thread will kill any program currently running in that Thread. Please post ...

Re: Messed up program access

Hi Scott, In regard to the spindle not turning on all the time in Mach turn, I tried to get a better observation of the way it is acting. Once the spindle is on, changing the speed seems to always work. M05 always works. When M03 or M04 work, the console shows the actual running condition. When the ...
