High Side - Low Side Driver selection
Not at the moment, my gate drivers are cooked from previously running them in the wrong mode... I gotta swap them and that kind of rework takes a long time because the drivers have a center pad connected to a ground plane... What I can tell you is that the gate voltage is in fact 15V higher than the motor voltage on the high side FETs, which tells me that the bootstrap cap is correct thus far. The problem I think I'm having is that the driver can only source 4A peak, and I'm seeing that I might need 5-7A peak...

Altium - Invisible unrouted nets/components?
@ThePhoton I do get unrouted net violations, not using online DRC.

@PeterSmith - had the same thought, tried that too. Nothing there. Selected the whole area and deleted it... Still persists.

@PeterSmith That did not work - tried already.

Isolation Amplifier Gain Problem
@Jeroen3 it's measured as a differential voltage a the output. I've confirmed it with a multimeter and an NI DAQ.

Isolation Amplifier Gain Problem
@DwayneReid I cannot show the rest of the circuit. It's proprietary. It goes into a rather high input impedance - ~1mA or less draw.

Altium 18 Place 3D bodyl dialog box missing
@RemcoVink thanks, I found that as soon as I clicked on the "Place 3D Model" button, my properties menu disappeared. It took me a while to find that it had collapsed the menu and turned it into a tiny button on the top right corner of the screen.

Accelerometer readings
Thanks Jim, I should have clarified, the dampened sine wave was because I pinged the side of the motor with a hammer to make sure I could get an output from the charge amplifier. Otherwise, I'm expecting a sinusoidal wave at some frequency.
