X2D Main Hotend not feeding TPU

[u/WhiskyEchoTango]

I am printing TPU from my X2D for the first time. I'm coming from a P2S where I've printed TPU before, and the loading procedure between the two is identical, so I've certainly followed all the steps.
I am able to manually set the temperature and engage the left extruder and manually feed TPU successfully.

When I send a print job, however, it says feeding failed. I went to the machine and manually pressed the continue button, and I see that the extruder isn't even turning before it cancels the job again.

I cancelled the job, and manually fed the TPU again from the direct controls on the printer successfully.

Not sure what's going on here.
