Yep, looks like we messed up and gave you two Y-axis motor cables and no Z-axis motor cable. Can you please email support@farmbot.io with your shipping information so that we can send you a replacement?
I got a v1.3 and instructions are v1.2 but im assuming z motor is essential I’m not able to check whether on this because the electronics and wiring part of the site is down
Sorry about that! I’ll have a replacement z motor cable sent your way. Please just send an email to support@farmbot.io with your preferred shipping address.
