Hi Giancarlo, I don't entirely follow the grounding. I think the 24V circuitry should be isolated from the KFLOP GND, I consider earth/chassis ground to be noisy so I wouldn't connect it to the shield around cables with signals. When you say we can scope for bits 0 and 4 you mean the first 8 bit fro...

Hi Giancarlo, Yes ServiceAux is a function pointer that points to a function to perform the next step in the communication sequence. If an error occurs communication is terminated and the pointer then points to an idle function. What Version of software are you using. Some older Versions had some Ko...

Hi Thomas, Rapid moves work fine with jerk limitation but with trochoidal milling or high feed milling the paths with high feedrate (sometimes the same speed as rapids) have to use G02 or G03. But I will look into my CAM Software if some paths could be converted into linear G00 segments. Well that w...

Yes it should be in 5.4.2 when we release it.

Hi Roberto,

New patch to place Backup Folders under currently loaded Screen Script Folder.

KMotionCNCScreenEditor.exe

Please let us know of any issues.

Hi Thomas, Yes we are always looking into this but it is very complex. For example following a U shaped "smooth" path will still require infinite jerk unless the path is reshaped. Doing this with potentially hundreds of 3D points/segments through multi dimensional paths is extremely difficult. Many ...

Hi Thomas, I was thinking moving relatively slow would allow software sampling. Adding hardware capture registers for all the encoders would use significant FPGA resources. Software encoder sampling at 90us at resolution of 0.1um can be achieved at: 0.1um / 90us = 1.1mm/s Moving fast at say 100mm/s ...

Hi Tim, I'm not sure I understand, but isn't there a way to write the GCode so G52 is not used for the absolute moves and therefore doesn't need to be set/cleared. For example set a fixture offset to run the local GCode. And one "zero" fixture offset for the absolute moves. Or use G53 to make the ab...

Hi Sahil, The 74AT14 Data Sheet shows a maximum input high voltage of 2.2V @3V. At 3.3V it might be 2.4V making it somewhat marginal for the Outputs with pull down resistors. The 5V 74ACT14 version has a max input high voltage of 2.0V so might work better. You might be able to drive optocouplers dir...

Hi Sahil, The 10ma is just a general recommendation especially if a lot are used. The 3.3V LVTTL outputs are rated for 16ma minimum. 16ma is sufficient to pull up the voltage to 2.4V which is a valid high for LVTTL (2.0V max threshold). The outputs with pull 150 Ohm down resistors can not source any...
