Re: USB cable starts overheating when Power Supply is turned on
Apparently all the other stepsticks were also burned. According to the seller who is checking my board now. Weird, because with those three stepsticks my board worked fine, it only didn't work with...

It's not really the resistance you should be measuring, although you can if you want. Normally, you measure the voltage between the trimpot "wiper" and ground. Obviously you need to have them...
View ArticleRe: Optos vs Microswitches
I use miniature glass reed switches. They are extremely reliable, have exceedingly accurate resolution, are resistant to shock and vibration , humidity etc and will last millions of switching cycles.

... I've found them not precise enough, when targeting on 10 microns or better accuracy/repeatability in 'harsh' environment -- so I'm using high accurate inductive sensors or special optical sensors...
View ArticleRe: Optos vs Microswitches
That's what I have the really small glass reed switches. But I'm not sure how to hook them up for use on my reprap. I've tried to find info on them but reprap pages just refer to them and that's it.

I would recommend that you try another stepper driver. If the other driver does not show the same problem, then the driver you talk about is blown. Also, you really should turn off the power, BEFORE...

Hi! I started repraping not so long ago and I already run into troubles: After I plug power to Melzi board extruder heater starts heating. Temperature sensor works ok - I can see proper reading in...
View ArticleRe: Melzi - problem with extruder heater temperature
One side of the load/extruder, is tied to V+, e.g. 12V. As a result V+ appears at that point always, as long as psu is turned on. The mosfet is a low side switch, meaning mosfetsinterrupts the gnd/low...

I think there is a short circuited path in your circuit or in the cable. Check everything before using it again,
