I'll agree if Windows is in play. On Linux, I regularly run 12 to 16 hour runs from my laptop, and never an issue. Once again, advanced platforms don't have problems, just WhinDuhs, or so it appears . . . Oh, and I leave it alone when running too . . . The time and effort to upload to SD just doesn't seem to be worth it for me . . . and dc42, don't feed me the crap about USB and no flow control .

Micro ohm meters exist for this, but are prohibitively expensive (the cheapest I saw was over $500, many in the $1000's) . . .
and thus my suggestion to select based on ratings. Cross sectional area largely determines resistance and current carrying capability, so AWG, BFD, FTS, or whatever really are not anything more than units of measure - IE 2mm wire is 2mm wire, and should behave similarl

On runs that short, it's easier to just look at the current and length, and select accordingly . . . . wire sizing isn't rocket science . . . .

Check the baud rate in Configuation.h . . . I think one of the changes that got pulled was that they inexplicably altered the comm baud rate to 115200 instead of 250000.
And if commenting out the INVERTED_HEATER_PINS define works, you errantly have the v1 board defined somewhere, and not the v2 . . . that's really the only difference in the code v1 to v2 . . .
I have a separate git tree where I

The define for RAMPS-FD v2 comes from the board definition in Configuration.h, not pins_RAMPS-FD.h . . . What do you have there? And what output is your extruder on? The way RAMPS-FD uses it's three power inputs makes it a bit different than other things. If you still have an issue (and depending when in time you got Marlin4due), comment out INVERTED_HEATER_PINS or INVERTED_MOSFET_CHANNELS in pin

M502 loads default values, M500 writes to prom.
M503 displays what is in the prom, and M501 recalls it manually.
So, an M502 followed by M500 will allow the settings you compiled in the take effect.

I was the guy who did .25 . . .
At .35, long prints got the motors so hot that the corners deformed . . .
At .25, I ran just warm to the touch . . . .35 really is 'at the wall' for these motors (.4A rated) so .25 really isn't down that much.
This is after 20+ hours of printing, and all my rails have loosened up and work in nicely. Were they as tight as when new, I'd be concerned about skippi

The Hackaday article has links on how to unbrick, IIRC . . . and FTDI has been reported to have rescinded the predatory driver as well, so you should get that version off your box as well.

All that will happen if the connector is reversed on a stepper is that it will run backwards. And on mine, they are all oriented the same direction, but I don't recall if I had to reverse it in software or not.
Any chance you have volumetric extrusion set? Try M200 D0 and see if anything changes, otherwise, about all I can think of is Vref for that driver (or bad driver), or steps/mm . . . or po

I didn't bother hacking the MOSFET control on my card, since I couldn't duplicate the problem, ran the V1 definition, and other than fan control being inverted (had to patch that) and running fine . . . considering that the MOSFET inversion is extra code, I would think the V2 def would be fine .

Pretty much, or if you have it integrated as you say, open the .stl from Pronterface and let it call Slic3r. Less to go wrong doing it separately, though . . .

Sounds like you are missing a slicer (Cura, Slic3r, etc.) to go between the .stl files and gcode that the printer can use.

Marlin *IS* lean in the sense it doesnt have bloat from useless UI code . . . and the rest is largely conditional at compile time, so what's in the codebase vs. what hits the flash is only loosely related at best.
Cooling is a BS argument since either could be made to work fine. Put the chip on the bottom of the stepper module, and a copper plan, heatsink on the back and done . . . pin for pin c

What do the temps show when that happens?

I can't really comment on the distro, since I have basically evolved my own based on Slackware over the years . . . it all kind of depends on how *nix literate you are. Slackware was the closest to admin to commercial *nix products at the time I chose it . . .if you need something a bit more turnkey, other distros may be a good pick, but I have not used them. Ultimately, they are all the same stu

M302 is the gcode for that override, although I don't personally know if Repetier supports it, although I would be somewhat surprised if it didn't.

*IF* the printer does not lose home, skip steps, bind, etc. Then dual endstops could be useful.

Yeah, and it's not like editing a config file and uploading it is much different . . . yeah, no compile, but for me, that's 30 seconds to a minute at best . . . Seems like a solution in search of a problem . . . once the config is set, no need for any of it anyhow . . .
And I like Marlin for it's leanness as an embedded controller. In my mind, web interfaces and all that secondary crap has no pl

Can anyone whom uses the lcd tell me how to print from sd card. I can't get mine to print no matter what I've tried.
Click for the menu. Scroll to 'Print from SD', click to select. Scroll to the file you want to print, click to select. The printer should home, heat, and print at this point. If not, verify that the temps it is trying to hit are rational . . . it won't start until both

Linux is flawless, and one of the primary development platforms for this stuff. It does have appropriate drivers, but it's more because Linux uses more broad reach drivers (USB serial is USB serial, so one driver for all) rather than the proprietary 'always need to get a nee one for every little variant' mess that is uSquid . . .
Some folks say that 250000 baud is problematic . . . I've been ru

That exploded view isn't your extruder, not even close . . . The lack of a heat break is unusual . . . not exactly sure how this is supposed to work . . with the heater basically clamped into the sink, and no heat break, how do you maintain a cold section on this thing exactly? And is there a fan directly on that heatsink? If not, the problem, at least to me, is pretty apparent . . .

When did Folger ever ship 16 tooth? Tne older kits were 36, and then they went to 20 tooth . . . and I have not heard of any change, although folks could buy extra 16 tooth if they so chose. And 16 tooth would cause him to come up short, not hit anyhow . . .
Hitting the table may be nothing more than having the height parameter set wrong. When you just get to the table, what do you see as your h

Nope, not needed, at least in recent Marlin. The ...GRAPHIC... define alone adds all the other stuff needed on Configuration_adv.h . . .
Addition of U8Glib is needed, but it should give compile errors without it . . .
Foger's 1.0.0, 1.0.2, and 1.0.3-dev all work here with the single define . . .

If you take the nozzle off, but leave everything else in place, does the filament move freely through the head? It almost sounds like either the throat is undersize, or the filament is oversize . . . Any change you have a 1.75 mm nozzle on a 3mm feed? You don't say what diameter filament you are using . . .

I don't know about you guys, but I find that an emergency stop is a lot of things, but useless isn't one of them . . . And I'd rather have it that some other function that could more easily implemented as a macro in Pronterface . . . such as filament load and unload . . .

I already have the Robotdigg carriages and effector, and they are very well done. The problem now is that they have apparently ceased to offer affordable shipping, and I didn't want to spend $40 to ship a $55 corner set, but now, it appears that there is little other choice.

Steps/mm should be 80, not 100 for current kits with 20 tooth pulleys . . . you are moving too far.
And now the bad news . . . . once you correct that, you will need to redo your zeros and calibration . . .
Not sure which Marlin you are running, but in 1.0.3, you set DELTA_PRINTABLE_RADIUS in the beginning sectionwith the delta defines. If I recall correctly, the older versions had MAX_PROBABL
