Sonic Pad + Vyper

I have a Vyper and have see online that a few people are using the Sonic Pad to control it with. I’ve followed the guiode in Ricky Impey’s video on configuring the Vyper and the Sonic Pad, but when I go through the calibration steps after installation, I get a “No trigger on probe after full movement” messages for calibration and Z-axis movement?

Any ideas on what may be the problem?
