Re: need some AMC analog amplifier Gain tuning help
the analog output does not even effect the drive Seems like we just keep going in circles. Its very simple. The DAC voltage must control the level and direction of the motor torque. If it doesn't then the Drive is bad or configured wrong and there is no point in going forward and trying to Servo. A...

Again, I don't think it is necessary to sit still.

Re: Kogna debug suggestions
Btw KFLOP/Kogna temporarily uses the beginning of the gather_buffer (< 128KB) during bootup so don't expect that to be preserved after re-boot.

Re: 5 axis CNC Router/3d printer
Very strange. But you need to check the KMotion Axis Screen not the DROs. Those are the raw motor positions.

Re: need some AMC analog amplifier Gain tuning help
I'd test the drive first before trying more complicated things. Commanding small DAC voltages should command the motor current (torque) proportionally and both + and -. If this doesn't work moving forward doesn't make sense. Current Limit should have no effect unless the command current is greater t...

Re: 5 axis CNC Router/3d printer
Hi George, So I would expect that to be caused by an issue with the C or Y axis. Record all the Destinations of all the Axes on the Axis Screen before and after the moves. If the destination is the same but the position has physically moved that should pretty much exonerate KFLOP or any software iss...

Re: On hower
Hi Taras,
Maybe you are referring to the Chip Program donated by Rick Caddell included as an example in 2020.
See the Release Notes here.
It is included as the VB Example named Chip.
Note it is quite involved to configure/modify for different types of systems.

Re: 5 axis CNC Router/3d printer
Hi George, Regarding the "backlash": It isn't clear what you are measuring with the dial indicator. The "length"? That is the "tool" is pointing in the +X direction. The dial gauge is measuring the end along X? With G49 when moving C nothing else is moving correct? Regardless, record all the Destina...

Re: need some AMC analog amplifier Gain tuning help
Do you have the switches set the same? You might connect the Tach + and - inputs together and to TACH GND so there is zero tach input. Also Ref + and - inputs together and to Signal GND so there is no command input. The offset Pot should then operate as a current command input. Note because it is op...
