Re: How do I properly measure the current of power supply?
I modified the Bench power supply I built before instead working on the previous one. cdsc_0057.jpg cdsc_0059.jpg Four modifications I made which mentioned on the wiki document() - 50 ohm resistor...
View ArticleTrying to figure out fan control
I want to get fan control figured out for two reasons. First the fan for the heat sink on the hot end almost never runs, only the odd random time. Second my printer can't bridge worth a damn (using...
View ArticleRe: Trying to figure out fan control
I would wire the heat sink fan permanently to the power supply input. If it's an all metal hot-end, you cannot afford to have it switching intermittently. I am not familiar with Azteeg, maybe someone...

The 32-bit boards have other advantages too, such as software control of motor currents, built-in web interface, and high speed uploading to the SD card (via HTTP or FTP in the case of the Duet). You...

@Traumflug: You should really try the 32 bits. You might even be able to come up with a better version of your 8bit Firmware. And they are also available in Packages you like ;-) Cortex-M in DIP
View ArticleDo I REALLY need an SSR?
I'm just now running test prints of a new PCB heatbed. It's 300x300mm, with a measured resistance of 1.5 ohms. Currently, I'm using a RUMBA board, an ATX PSU @12V/52A and an SSR relay. But by my...
View ArticleRe: Do I REALLY need an SSR?
The RUMBA board has a design flaw, which is that the mosfets it uses are not intended for 5V gate drive. Any particular board will probably be OK up to 11A heated bed current, but it is not...
View ArticleRe: Do I REALLY need an SSR?
Cheap SSR's have higher resistances than good quality MOSFET's for controlling the current due to using cheaper parts. People also underestimate the impact of a little bit of extra resistance when it...
View ArticleRe: Do I REALLY need an SSR?
Hmmm, so then I probably don't need the ssr realistically, right?

View ArticleRe: Do I REALLY need an SSR?
Most people will be satsfied with IRLB8743 or IRLB3034 MOSFET's unless they spend a lot of money on a good SSR. You have to check the specs of the SSR to see what the On Resistance is or the expected...
View ArticleRe: Do I REALLY need an SSR?
Hmmm. See, I was hoping to avoid more messing about with the electronics. In an ideal world, I'd like to be able to just go down the normal route of PSU>Rumba, Rumba>Heatbed. I'm pretty sure...
View ArticleRe: Do I REALLY need an SSR?
If the RUMBA board used appropriate mosfets, you would definitely be fine driving that heated bed directly from it. As it is, you will probably be fine. DC SSRs typically drop around 2V at full load,...
