It can be one piece.
I want to make a heatsink for my 3 axis board.
Can I make it in the one piece, for the 3 ic's or do they need to be electrically insultated from each other.
A single strip of alumin(i)um was provided with my board for just that purpose. I will also be adding heatsinks to the voltage regulators as I saw on the Yahoo group that some people were getting 'hot' regs. Don't forget to use heatsink 'compound' when you add the heatsink(s).Originally Posted by xairflyer
just make sure that the metal heatsink tab is ground on the to-220 vreg and the stepper controller and that the heatsink touches nothing but ground. (I dont own a kit but I've seen pictures of it) you can pick up a heatsink for the vreg at radioshack + mounting hardware and thermal paste. If you build pcs and have cpu compound, that will work great too.
i used heatsinks out of old pc power supply
I have used heatsinks from old AT powersupplies as well. I found a really big aluminum heatsink that just fit the X and Y chip and a smaller width one that fit the Z chip.
Hi All. Newbie.
So the heatsink is definately neccesary, yes ?
If it generates heat, put a heatsink on it. Better to be safe than sorry.
If it's not nailed down, it's mine.
If I can pry it loose, it's not nailed down.
Yes, IF using 2A or more per phase steppersOriginally Posted by janpo
