Hi Scott, The device specification guarantees the pin should be below 0.4V for a load of 40ma. A 10K Ohm would only draw 0.5ma at 5V. So something is wrong. LVTTL signals are guaranteed to be low at 0.8V but should be driven to 0.4V for noise immunity. Are you connecting the ‘+’ pin to +5V? That see...

They are 3.3V LVTTL and 5V tolerant.

M99 (subroutine return) wasn't intended to be called without a subroutine call. The previous looping behavior was unintentional and only worked in certain cases. It now fails if the file has an UTF-8 BOM at the beginning of the file. We will fix this in the next Version. In the mean time M47 can be ...

But, now that I think about it, I recall the manual mentioning that the 12v supply was a convenience for providing power to other devices and not actually required for driving the kflop circuitry so that explains why I'm not seeing it. Correct. 12V isn't connected to any KFLOP circuitry. It is only...

Well there is a lot of circuitry between 5V and GND so it is not surprising for an Ohm meter to measure some continuity.

I'm not able to reproduce this. I run the example Subroutine.ngc without error. Does it run for you? Can you post a small GCode file that demonstrates the error?

Hi Griffin,

I sort of doubt it. Normally the axes aren't enabled and disabled. Normally after being disabled the axes are re-zeroed anyway. Also the high frequency burst of pulses is usually ignored by the Drives. But yes, please update to 5.4.1 to eliminate this possibility.

No there isn’t.

Sorry to hear this. Reversing power is one of the worst things that can happen. We don’t find it cost effective to repair boards. Especially in a case where multiple things are likely damaged. If everything isn’t fixed then applying power may cause more damage. The caps probably aren’t shorted rathe...

Please re-Post your initialization C Program and Mach3 Profile and we can look at them to see if they are now correct. Make sure you post the Initialization C program Mach3 is configured to use. I can't see in the video what you are doing and what is happening. Its better if you explain. You should ...
