Re: Arduino Uno Electronics
Only very few printers use max endstops. If you're short on pins this would be the first one I'd remove. One enable pin for all axes is fine, too. Your printer is either off or moving on all axes....

There is no technical need for auto-reset. It's more a convenience for easy firmware upload. In fact, Melzi has a jumper to turn this off. If you don't reset, you find the controller in exactly the...

Thanks for the advice. I guess that if you have min endstops and configure the size of the RepRap's printable area, then the software should know the max. I will put my enables all on the same pin has...

Hey guys, I've recently finished adding bed and fan support to my Gen 6. I just updated the Gen 6 wiki page with details on how to get to the pins. You can see my solution below. If theres interest I...

And if you separate Z motor enable to one of the last free A pins, you could disable Z motors, because during printing Z is the only one that even can be disabled (because stepper hold its main step...

I agree it would be nice to drive the FETs at 12V, but with some of the newer FET's it doesn't seem necessary. I'll be using the IRLB 8743 which seems to do pretty well at 5V. It would be better at...

Agreed, with most FET's, you are limitted to 20V without having something to drop the voltage down. someone wanting to run 24V would need to supply a lower voltage to the FET driver from someplace...
View ArticlePowering Raspberry Pi from RAMBo?
I'm putting together a custom Rostock and I'd like to be able to run a Raspberry Pi and a RAMBo from just one power supply. I'm not the best at dealing with electronics--I cooked one board already so...
View ArticleRe: Powering Raspberry Pi from RAMBo?
The Pi will draw 500~750mA. According to the RAMBo schematic, you can find 5V and GND on X1. You can also find 5V and GND many of the expansion headers (SPI, I2C, Serial, PWM, Motor). 5V amd GND can...

Controlling your Reprap via Wireless or Even Over the Internet [Guide]
This is the outcome from a previous thread, but as I have made progress I thought it merited a more apt title. I have managed to attach a HLK-RM04 module to the Aux-1 port on my RAMPs board and by...

View ArticleRe: Sanguish development
It's a good suggestion and something I've thought about before. I'll have to do some testing and see how much cooler the FET will run at 12V. If it's significant I'll have to try it. I'm excited to...
View ArticleRe: Controlling your Reprap via Wireless or Even Over the Internet [Guide]
That looks good. Only thing I find limiting about any of these 'remote' options though (including just plugging in a Raspberry Pi), is you're still limited by the serial baud rate - it's takes several...

From what I'm seeing, you're using sockets for the Servo Drivers. Any issues with those that anyone has seen at the 2A level? Any potential issues with those at 3A, or do you think in that case we're...

I don't think there is an easy answer to the speed problem. Of course, having an onboard MAC is the best, but that loses the advantage of a standard external module, which is to save a lot of...
