Nah. No worries. Obviously the grease you are applying is sufficient for 99% of the builds. There was probably some inconsistency with my printed parts that needed a little extra love to overcome. That said, if every build I did was perfect the first time out, I’d probably have grown bored with these hobbies years ago. I find most of the fun is in the building, troubleshooting, improving and improvising. The stuff I make is just a cool benefit that helps fuel the hobby. I don’t think you really need to worry about including extra grease in the kit (unless you are able to source at some ridiculously low price). Just a mention in the build guide would suffice. Even if folks do not heed the advice during the build, they will surely see it when they refer back to troubleshoot an issue with the axis movement.
