XRP V1.0 doesn't work after putting it together

Hello,
Has anyone put together a new XRP (V1.0) successfully? I have put together many XRP beta versions without any problems. I just purchased a V1.0 of XRP and put it together. Unfortunately, when I go to run even a simple instruction or run the installation verification program, it gives me a motor error. I just want to make sure that the unit that I just purchased doesn’t have an issue. Thanks.

Double-check that all of the motor connectors are seated (I’d pull them out and inspect the pins inside too)…if you don’t see anything obvious maybe swap the motor giving an error with another one and re-test

Hello,

I took both motors and put them in another XRP (beta) and they both worked fine. I tried the new V1.0 again and got the following errors when I tried to run a simple program (Straight 10: cm Effort 0.5 and Turn Deg: 90 Effort 0.5):

Traceback (most recent call last):
File “”, line 37, in
File “Installation_Test_March23.blocks”, line 3, in
File “/lib/XRPLib/differential_drive.py”, line 22, in get__1"

File “/lib/XRPLib/motor.py”, line 61, in init
ValueError: unknown named pin “MOTOR_L_IN_1”

I think when I first started it (after putting the new V1.0 XRP together) and tried to update both with the newer version of MicroPython and XRPLib, something went wrong and didn’t get updated or got corrupted. I removed version.py to force an update but didn’t do a complete update of both. Any suggestions as to how I can force a complete update of both again?

Thanks again.

Here’s what worked for one user XRP only ever appears as a USB drive
