Hi Tom, I'd rather stop getting prizes like these :) Can't upload the datasheet for the sensor as it's 3.2 MB. It's Omron_EESX3173_EESX4173 and you can see it online. With the USB isolator connected you can't do anything as when you try and press INIT in the KmotionCNC it crashes and you have to for...

Hi Tom, I installed 6 pcs of 1 nF filter capacitors right next to the KFLOP, replaced all the limit switches with ones from Omron- as per the attached datasheet, on which I connected a 2K resistor between Output and Vcc. Also bought the USB isolator you suggested but as soon as I connect it to the K...

Dear Tom, Good. But that's the sensor. What is the circuitry on that board and what is on your prototype board? That's the circuit of the limit switch. The prototype board has only connectors on it so that you can disconnect limit switches and drivers from the KLFOP. It has no other components. Each...

Hi Tom, Managed to find the model of the optical limit switches. Attached is the datasheet. Still can't get the board to work although no limit switched are connected. Checked the soldering of the connectors on the prototype board and there are no shorts and 5V are supplied by the KFLOP to all limit...

Hi Tom, Its not clear what you mean by "GND of the limit switches". It should be a short connection to KFLOP GND. I mean the GND pin of the limit switch, which is connected to the KFLOP GND. You might describe your grounding. What is the topology? Is everything isolated from Earth GND? Grounds from ...

Hi Tom, The limits are configured "Disallow drive into limit". The Console's message is "Pos Limit Disabled Axis", followed by the respective axis No. On a small prototype board I have soldered the cables from the KFLOP to connectors for all the limit switches and motors. The cable is 20 cm long. On...

Hi Tom, If the inverter, respectively the spindle, is running and you try to jog any axis in the KmotionCNC, it moves a fraction of a millimeter and gets disables and it's DRO becomes yellow. Neither the inverter nor the spindle is attached to the CNC running on KFLOP. Those are just plugged in the ...

Hi, I finally managed to setup my KFLOP CNC and ran a G-code in KmotionCNC with the spindle OFF. However, as soon as I start the inverter for the spindle, or if it's already on before running the G-code, KFLOP almost instantaneously disables the axis. The limit switches are NOT triggered when the ax...

Hi Tom, I de-slaved the Y axis and in the Step Response screen it was moving absolutely fine at high speed - 50 000 and acceleration 200 0000, and when I lowered it to let's say 5 000 it was not moving at all, which was odd. So, I swapped the drivers of the Y and the slaved axis and it turned out th...

Hi Tom, Thank you for your exceptionally quick reply!Her below is the initialization programme: #include "KMotionDef.h" // Defines axis 0, 1, 2 as simple step dir outputs // enables them // sets them as an xyz coordinate system for GCode int main() { ch0->InputMode=NO_INPUT_MODE; ch0->OutputMode=STE...
