RatOS giving errors communicating with LDO Input Shaper kit

Stock V Minion from a kit. LDO input shaper is on the raspberry pi (being powered externally temporarily so I could put the input shaper hat on it). Getting an error when I try to run input shaper about invalid ID. Single ADXL is set in the configuration. I tried the another printer with MainsailOS and it worked well, so I'm thiking it's something sofware related. Yes, I've checked my ribbon cable wiring twice already. Happy to send any files / pictures as needed.

always helpful when you upload your printer.cfg

input-shaper-single.cfg uses an ADXL345 connected to the MCU. You're deviating from stock, that's why it's not working. To make it work, go to user overrides and paste this: 
[include RatOS/sensors/rpi-adxl345.cfg]
[resonance_tester]
accel_chip: adxl345 rpi
[include RatOS/sensors/rpi-adxl345.cfg]
[resonance_tester]
accel_chip: adxl345 rpi
When issuing accelerometer (not resonance testing) commands you need to reference the chip name. For example MEASURE_AXES_NOISE CHIP="rpi".
