Just a note to say, my upgrade is complete and have managed to sort through all issues. Everything is running smoothly.
Thank you for all your support.

Hi Tom, Thank you again for your help. I had not imported the program. The problem was resolved once I had done that, and the steppers are all working again as expected. The upgrade to the SnapAmps is now almost complete. However, I have a couple more issues that have surfaced; one with the touch pl...

Tom, For now I have decided to move the physical home position to accurately sync with the homing function. As I am going through setting up the SnapAmps, I am now tuning the axes. There is a problem with the Z-axis responding to the Step/Response values at the moment. The Z axis stepper stalls at r...

Thank you Tom, that is good information to know. I will give this some more thought and decide what will work best for my setup. I'll let you know. On a different note, I rewired my stepper motors back to Bipolar-parallel, to make more use of the higher current from the SnapAmps, and one of the chan...

...update. I have tested actual movement, using the incremental jog function within KmotionCNC, with dial indicator, and I am able to move in 0.01mm increments. So the resolution is there. However, when attempting to set the machine home to a specific accurate position I am not able to get more accu...

Hi Tom, I have swapped out my KStep, and installed two SnapAmps instead, to handle the current drawn by the steppers better. Steppers are rated 4.5 Amps. This was my prime concern, however, I had not considered how this change in hardware would affect the machine resolution. Now that I have everythi...

Sorry, I meant SnapAmp.
Thank you for your prompt reply, that information is exactly what I was after, and I should be good to go from here.

Thanks again!

I meant to say, I also have a Konnect board in this setup if that changes anything.

I want to change out my KStep board and use two OpAmp boards for my machine instead. Does the Flop board have a PWM output I can use to send the speed control signal to the spindle inverter, and how would I configure that?

I am using KFlop with KStep board, driving a 4 axis cnc machine with stepper motors. The steppers are wired to be within the boards rated current. However, I would like to increase current to the Zaxis above the rated current of the KStep board, and therefore I am thinking of using the SnapAmp. Is i...
