Building my first 3D printer, taking a long time because I have been distracted by household DIY jobs and to be honest I have been procrastinating, most likely overthinking things.
Anyway, I have got to the first belt (the one on the bed) and I’m not sure how much spare to leave when I cut it. One of the first things I intend to print is the belt tensionsers and I understand that you need a longer belt to accomodate this.
But I don’t know how much extra I will need so where to cut the belt - and if I cut too juch then there won’t enough for other belt.
So can anyone advise how much extra length I should leave to be able to accomodate the tensionsers - are we talking a cm, 2, 3 or more?
I left about 3/4 cm on the y axis under the bed and mounted the rest on the x axis checking that the extra belt didn’t interfere with the motion, at the end I didn’t even need that extra length but it depends on what type of belt tensioner you will use, so try to make your choice thinking about it.
PS: don’t over tight the belt or the frame will bend (expecially on the y axis), I suggest you to print some frame reinforcement if you’re going to put belt tensioner and even then don’t over tight the belt.
