I’m new to the forums, so apologies if I’m not following some sort of protocol.
I just saw Karthiks ruling on 3D printing cable chain for cable management as shown below:
“This is not permitted in VEX U, unless the 3D printed part were come out of your allowance of as . This would definitely not be permitted in the VRC. Essentially any wire management devices must be commercially available to be legal as per <R7l>. i.e. You can’t just use random materials for a home made cable management solution.”
I have to say I am very disappointed. We are allowed to purchase cable chain in the high school VRC according to the Skyrise rule book as long as its sole purpose is for cable management. If this is the case, what harm is there in allowing 3d printed cable chain? It does not give a team any particular advantage, in fact it would be easier to just buy the stuff, its not expensive. However it is an awesome learning opportunity for the students. I recently got a 3d printer for my classroom and would LOVE for the students to CAD up their own cable chain for their robot. Karthiks ruling makes that a no-go.
I completely understand when rules are made to keep the playing field even, but in this case there is no benefit regarding the competition. It would solely be an awesome LEARNING opportunity that would not affect match play in the slightest.
Having said all of that, I could be wrong…so please chime in with your thoughts. I’m guessing someone will mention “saftey”, but I honestly don’t know how 3d printed cable chain could be unsafe in the real world. Maybe if enough people feel as I do they will change this rule next year.
By the way if you don’t know what cable chain is, it is simply a special shaped chain that allowed wires to be safely run inside for protection and management. Just google “cable chain wire management”
I am NOT for rules that give certain teams more advantages than others, but this limit on 3d printing cable chain isn’t really doing anything to keep the playing field even. Whether I buy or print the stuff myself, it is cable chain…its not complicated stuff.
By the way, the vex forum is awesome. The community is remarkable and I have learned a lot from many of you on here. I’m glad to finally be a member and hope to join your conversations often! I am the teacher for teams 4149G & 4149C from Minnesota. We have been doing VEX for 3 years and have made it to Anaheim the past two years! Been fun!
