I suggest looking at the maximum amperage draw for all components that could be on at one time, and then find a power supply that can supply at least 20% more current. You would never want to get a supply rated for lower current than your max draw, because then it will affect the torque or your motors, or the temperature to which your heaters can get. ...

Good morning, and welcome to 3D Printing SE. You said: "I can see information from the printer via USB in RepG and through OctoPrint, but can't send any prints, commands or upgrade firmware (I wanted to flash Sailfish 7.7 eventually)." This means that the USB communication is working fine. It isn't a question of drivers or the FTDI interface chip. That ...

What's the part number of the regulator you're putting in? The pin assignments vary from one part to another, but you can probably find them from the part number online. Some parts have the ground pin also connected to a metal part of their case. The green wire from the board should be ground (no promises!) Assuming you've got a voltmeter, you can use it to ...

You can find gcode information at the RepRap wiki. The obvious other thing to try is G1 X10 for a move. Octoprint prints by sending the individual file's gcode one line at a time over USB. It appears that the firmware on your printer might not respond to any 'action' commands over gcode, rather than any fault as such with your hardware/software setup. ...

A short, figurative answer from the electronical point of view: A power supply (an an analogy you can view it as a water pump) as used by 3D printers is usually supplying a fixed voltage (a constant pressure going into your pipe system), in your case 24V. The given amperage/current (the amount of water that actually flows) that is actually utilized at a ...

If you check the Mightyboard RevE files on Thingiverse (http://www.thingiverse.com/thing:16058/#files) you will find the schematics and PCB files (.sch and .brd) for the version of the board used in Replicator 1s and (with some minor mods) most clones. The Atmega 1280 IO header section is a bunch of breakout pins for debug functions. There are eight sets of ...

It is possible that your board has a cloned FT232R USB-to-serial bridge chip, and FTDI drivers supplied via the Windows update channel will not work with cloned chips. Try using the Windows setup executable from the following page: FTDI Chip: Virtual COM Port Drivers Note that there are no known problems with MacOS and Linux drivers.
