Also check to be certain that both first layer as well as main temps are correct, and uncheck ooze prevention - it will do crazy things with extruder temp. The point with start gcode, is that if you set temp (M104, M109) there, Slic3r will use that and not apply it's settings. - Timby tadawson - Slic3r

D9 should not be powered until an M106 commands it on, and is used for a layer fan, not the hot end fan, which should be wired to 12v directly. What voltages are you seeing? Supply out, board in, and heatbed out? Check also that you are not using too small a wire to the heatbed/board . . . 16ga would concern me, 14 may be OK, myself I'd use 12ga or 10ga to minimize losses. - Timby tadawson - RAMPS Electronics
I'm not exactly sure where you are measuring . . . the blue and black dots are endstops . . . - Timby tadawson - RAMPS Electronics
Looks like Chinese quality control at it's finest . . . good, fast, and cheap . . . pick any two! - Timby tadawson - Delta Machines
If it carries board/motors/bed/extruder, then 16ga is too small . . . If typical, and heat bed and *other* are separate, then perhaps you can use it for the motor/extruder feed, but for heated bed, I'd go with 12ga or 10ga myself . . . both supply to board, and board to bed. - Timby tadawson - Safety & Best Practices
If you have the same Folger parts I got, the only keyed connectors on the endstops are on the endstop end - the three pin connnectors will fit the RAMPS either way, since bare three pin headers cannot be keyed . . .The 5v line is the row of pins farthest from the board edge, and if your cables match mine, that would have the red lead to the inside of the RAMPS, black in center, and signal (white?by tadawson - Reprappers
I'm not sure what your power supply voltage is, but I'd be more concerned that you are losing that much voltage tomthe bed, period. That, or the power supply is weak - you might try the same test, but meter both the board input terminals, the board output terminals, and the power supply. Supply OK and board low? -> too small on the wiring supply to board. Supply OK and board OK? -> crappy Mby tadawson - Reprappers
Impossible unless you are stupid enough to screw with it while a job is running, and not that different than pulling out an SD card. That is not a technology limitation, that is user error, and dumbing things down because people won't (or can't) think is not a solution - it just creates and coddles more idiots . . .

Yeah, hide the SD where you can't get to it easily . . . .that makes lots of sense . . . I suppose if you only have one computer and stream porn and play games, it could be a problem, but that's user error, not anything else. And let's get off the Windows crap, OK? Just because they do everything as stupidly as possible does not mean those problems exist on more advanced platforms . . . and it'by tadawson - General
Yup - bowden on a kossel. The point was the use of macros to simplify the process, not the specific lengths . . . they might even be higher, I'm not at that system to verify at the moment . . . - Timby tadawson - General
Interesting that you mention filament size . . . I recently got a spool that had small sections that were over 2mm (on a 1,75mm spool) that would not physically go through by bowden tube. - Timby tadawson - Printing
Nope, that needs the Arduino toolkit (or IDE) as well. Not needed to print, but required to update/modify any Arduino based firmware. Also free . . . - Timby tadawson - Slic3r

If all you are powering is a board, no motors, heaters, etc. through it then the draw is so low that almost anything will work. I do not however, happen to know of any 3d printer controller/board that does not handle heater/motor power, though . . . what is it? - Timby tadawson - Safety & Best Practices
I would argue that the computer will be more reliable in avoiding data errors than trying to read an SD card over a very crappy chunk of unshielded ribbon cable. And, I can't speak for the WinTurd(TM) users, but my systems are available at least 99.995% (3 minutes out per year) other than for planned updates. Heck across 4 systems, I have not had a crash in over 5 years . . . remember, no WhinDuhby tadawson - General
I run an E3DV6-lite, and going from bright red to white, I am clear after 70mm or extrusion or so, although I'll usually squirt more like 100 to be safe. I have two macros in Pronterface - unload, which sets 180 degrees and waits formit (M109), and the reverses 450mm or so (enough to clear the extruder) and then wets 100 degrees awaiting the load. Load fires in an M302 (extrude cold), and runsby tadawson - General
Reading to where? When at max on the pot, from the wiper, you should see 20K resistance to the 5v line (as per Pololu schematics - who knows what the Chinese cloners have changed) and 0 to ground when at minimum. High USB power error indicates a short on the 5v rail, which will cause this - low 5v, low Vref, plain and simple. I'm not sure what you have plugged in, but if you have not tried it, uby tadawson - Reprappers

FYI, there is a Due port know as Marlin4Due which supports RADDS, and both versions of RAMPS-FD . . . The FD v1 support is very good and works . . . - Timby tadawson - RAMPS Electronics
Reversing completely, or just backing up on occasion? If the latter, check your retract settings in your slicer . . . Otherwise, perhaps a bad connection/solder joint on the direction select line from the Arduino to tne Pololu module . . -Timby tadawson - Delta Machines
Board input, as in power goes in and the to heated bed or extruder, or just to power a board? Cross section and diameter should be the same thing, I would think . . . And again, unless it won't fit the connectors, or costs too much, you can't error going larger. - Timby tadawson - Safety & Best Practices
I have been able to go from 0 to at least a volt. This is based on the 5v supply, so if the reg is bad, or an endstop is shorting it out, you may not get there. Heck, you can set Vref with nothing but a USB connection . . . 12v isn't involved. I run .35 on the axis, and .9 on the extruder, same printer . . . .35 does run hot, but comes in at the rating of the motor. I added heatsinks/fans to theby tadawson - Reprappers
No, I actually barely tolerate WhinDuhs, and only use it as a last resort. I am an IT professional, though, and run Linux as a primary platform, and ironically find that performing some maintenance actions for Win* is easier using Linux . . . But seriously, about the only thing a Win* install does to Linux is overwrite the MBR, which holds the bootloader. That is at the header of tne disk and oby tadawson - General
The printer only pulls about 2.5 amps from the wall, so while not reassuring, the thinnish cord is adequate . . . if not terribly durable . . . - Timby tadawson - Prusa i3 and variants
You botched something . . . you can reinstall either without affecting the other. Put Windows on part 1, Linux on 2, swap on 3, and whatever on 4 if you like. If/when Windows toofs, reinstall Win*, but do *NOT* allow it to repartition. Then boot into Linux with your CD and put the Linux bootloader back on, so you have access to both.

Quoteo_lampe Are you sure about the 115200baud? Marlin is set to 250000baud by default. -Olaf They changed the 1.0.3-dev tree to 115200 recently, FYI . . . not sure why, since it seems to be causing a fair amount of confusion . . .

Disable software_min_endstops while you calibrate, and then you can take Z negative. Depending on which Marlin version/date you have, there is/was a bug that it didn't consider M206 offsets in the soft endstops, so if you find that the base calibration puts you at Z=0 is one mm high, and do an M206 Z1 to get it right, and it still stops high, you needto update.

Run the Windows stuff you need in a qemu VM . . . it boots faster than Windows native, and passes all USB devices if desired. The only possible issue to cad, as you noted, might be graphics card acceleration access (and there are some better add-on drivers for this than stock in qemu . . ), but to date, I have found nothing I can't get to work.
