If they short components, you ought to be concerned. At worst it can burn your house down.

Well, that's a great help!
Most of the units I've seen have larger heat sinks that the A4988 chip. You need to cover it with a piece of Kapton or some non conducting insulation (having cut out a square for the heatsink to bond to the chip).]]> waitaki General Mendel Topics Sat, 16 Aug 2014 07:27:54 -0400 https://reprap.org/forum/read.php?151,395399,395419#msg-395419 Re: heat sinks too large https://reprap.org/forum/read.php?151,395399,395419#msg-395419 alvinhochun General Mendel Topics Sat, 16 Aug 2014 02:25:14 -0400 https://reprap.org/forum/read.php?151,395399,395399#msg-395399 heat sinks too large https://reprap.org/forum/read.php?151,395399,395399#msg-395399 Thelandofthedave General Mendel Topics Sat, 16 Aug 2014 00:22:56 -0400
