Hello, I have been trying to calibrate my machine to improve print quality for a few days. Today, when I wanted to heat up the extruder again to launch some test it, the cmd line gave me this massaga in xp: "No extruders avaliable." I checked everything, all cables, pcb possible shortcuts but all was ok. Does anybody know when software gives this massage? what part of pcb may have gone wrong? thanks, satuna https://reprap.org/forum/read.php?13,10382,10382#msg-10382 Thu, 15 Oct 2026 10:56:08 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?13,10382,10417#msg-10417 https://reprap.org/forum/read.php?13,10382,10417#msg-10417
The only way to deal effectively with this fact is to build your projects assuming that something's wrong which you can only track down when powered, but without frying anything. This is why putting car tail light bulbs or other series resistances in series with your +12v at power-on is such a common practice - if there's a fault, it lights up instead of turning your parts into voltage to smoke converters.

Also, messy wiring eats far more of your time than it takes to neaten - I use single core copper wire as used in network and phone cables as simple ties, and zip ties for more permanent installations. Not only does it keep things neat, but it stops loose wires touching *everything* if they fall out of a connector or melt or something.

I'm very lazy, and have learnt that the easiest and simplest way to get something done is to ask a busy person to do it because busy people are constantly looking for things to get done. Doing it properly the first time is the next best option. Just throwing stuff together creates time and effort drains, which are quite abhorrent to most people, and can easily suck a project dry of all enthusiasm.]]> Triffid_Hunter Controllers Tue, 18 Mar 2008 01:55:34 -0400 https://reprap.org/forum/read.php?13,10382,10409#msg-10409 https://reprap.org/forum/read.php?13,10382,10409#msg-10409
If I built up a whole board and then tried to test it I'd never be able to figure out where the mistakes were to be fixed.

I'd recommend my technique to anybody who has more than two thumbs. I must have 20-30. (td)]]> Forrest Higgs Controllers Mon, 17 Mar 2008 13:44:59 -0400 https://reprap.org/forum/read.php?13,10382,10406#msg-10406 https://reprap.org/forum/read.php?13,10382,10406#msg-10406
connections are ok - I suppose... I checked them a hundredmillion times...

Demented, did you have to change your PIC and it has solved the problem?

thanks,
