I've got two boards built for Sanguish 1.0 that I am currently testing and it is going well. I'll update the wiki soon. The final 1.0 version is essentially unchanged from the 1.0 RC1 linked in the...

Thanks for the input! I had a look around for the "resettable thermal fuses" that you mention and can't seem to find anything like that -what I keep finding seems to be more concerned with current and...
View ArticleRe: hosted thermistor reading high:S
I replaced the thermistor and it seems to be reading correctly now. Not sure if the thermistor was faulty or the install in the hotend was ( air bubble etc).

Search for "thermostat", or contact thermostat or surface thermostat, something like this one. Its the old principle of bimetalic component which swings one side or the other because each metal has...

Thanks for the information - I will have a look into these. We were thinking the same thing about the max temperature for the cutoff, that it should be the desired heated bed temperature (for example...

Hello. I'm using a RAMPS 1.4, the Marlin firmware and Repetier-Host for printing. I set up the heated bed max temperature for force stop in Marlin to 150 ĀŗC and the working temperature in...

I hope you dont use pid control on heated bed. In the picture i see the fan is set to on. What pin is allocated to fan in config.h or pins.h for fan, could it be same pin as the heated bed? Or you do...

Have a look at ZXGD3005E6TA. It's pretty low cost and has a peak output current of 10A. That's the absolute maximum of course, but it's still not bad.
View ArticleRe: Choosing Thermistor based on table - Marlin
Hello, can you confirm that the table from Noobman (April 11, 2013 12:15PM ) is working with that thermistor? I ordered a new hotend too and i need a good marlin table for the B=3950/100K. Thanks.

I did had a look at that some time ago when somebody else proposed it. The problem i see with that is that it is a current device, this is why datasheet has no VIH and VIL levels. It is controlled by...

If you have a multimeter with a thermocouple, the very best thing you can do is start with that table (or any other that is sort of equidistant - see the temperatures column goes in 10C and 20C...

We're just finished building a custom made heated chamber and noticed that waiting around 50 minutes the chamber reached a temperature of 41 degrees (105 fahrenheit). Now we're wondering what them...

So I had to do some sim to get a decent answer; thankfully, Diodes Inc. provides SPICE models for these devices. It turns out that the reason there's no VIH or VIL is that there isn't one. It's a pure...

If you have a heated build chamber, you don't want your electronics inside. FET's (used to drive the heated bed/hot end) and the stepper drivers need to dissipate heat when they work, due to their...
