I'm on Arch x64, building from source. Slic3r crashes before it can start, giving a segmentation fault. I've tried this both with code straight from Git, and with the 'slic3r' AUR package. 'slic3r-bin' works fine, but it's old.
This does not happen with --no-plater (or no gui), so it seems to be an issue with the plater.
Anyone else have this happen? Should I post the core d

I'm happy with mine, they delivered it about a month ago in three weeks, and on the few issues I had (missing screws, and a failed bearing) they responded within a day, and parts were sent immediately. There are a few things that you may want to upgrade (add a hot end fan duct and perhaps a layer fan) put it does pretty well as shipped, and made nice prints of those parts. For the price, it seems

QuoteThen you need to disconnect the PSU from the mains, wait a while (I suggest at least 10 minutes), then move the switch to the 110V position.
Or just switch it immediately. There is absolutely nothing in a switching supply to merit a wait, and the 12v will be gone in 5 to 10 seconds if connected to the printer anyhow. In this case, since no output wiring is being worked on, that is irrelevan

I haven't gotten mine into my printer yet (working on all the other subtle things first, since I don't want to install, hit a bug, and remove) so I have not confirmed motors working yet, but considering that it is the first thing I think the devs would test, hadn't spent much time on it. What I do notice is that I have not been able to find a doc showing the orientation of the Pololu modules ins

Looking at your config, I'd start with setting the thermistors to a valid value - hard to tell what you will get using '0', when the notes clearly state 'Not Used' for that value. Then, depending on what temp reads (thermistor present or not), heaters may lock out if temp reads too high or low, but you can temporarily tweak MAX and MIN temps to test.
Did you edit any other files?

Yeah . . . I run the Folger extruder at a VRef of .85, and the motor only gets warm to the touch, and it runs noth PLA and ABS fine. I am on the Kossel, and the extruder motor is larger than the axis motors as supplied, which may cause it to run cooler than a Prusa . . .

+Maxim Melcher in Google+ has successfully added an LCD 12864. He upgraded the 47uF 16V capacitor to 100uF 16V on his Due.
Thanks. Do you know if that was required to get it to work, or just something he did to beef up the Due 5v supply. (I plan to offboard my 5v from the Due anyhow . . . ).
Also, might you know what LCD define he used?

Check the grooved bearing in your Folger extruder. Mine died a horrible death, and any semblance of proper extruder function went out the window. I dropped in a replacement bearing, and all is back to as it was, running cleanly . . .

If you drop to 9.04 at the supply, the supply is either FUBAR, or is not large enough for the job. In either case, it needs to be replaced . . .
If you are only dropping .1v from the supply to the RAMPS heater terminals, that is doing pretty well, as is only losing another .05v between the RAMPS and the bed heater itself.
I think a good power supply will make you a happy camper . . .

Hello,
Ok I ran an extruder test here is the results:
- Clicked slow extrude 100 in Repetier
- Measured the total distance on extruded materiel 39cm = 390mm
This does sound way too high, correct me if I am wrong it should be closed to 100mm
where would I look for the steps per mm in the firmware. I tried changing this in Configuration.h :
#define EXT0_STEPS_PER_MM 370

Filament diameter in your slicer?
Tip size in your slicer?
Steps/mm in your config? Have you tested 100mm extrusion for accuracy with tube disconnected?
Head not hot enough to allow proper extrusion?
Blockage in the hot end (you fail to mention if anything extrudes at all . . . )

Check which connectors on the RAMPS the endstops are plugged into, or close one at a time by hand and execute M119 (or is it M114? . . ) and see which activates. On the Kossel, all the tower endstops should be MAX. The Folger docs have good pictures of where this wiring goes as well. . .

MANUAL_Z_HOME_POS gets set to the distance from your endstops to the bed. If G1 Z0 ends up above the bed, increase it. If you hit the bed too soon, decrease. MANUAL_X_HOME_POS and MANUAL_Y_HOME_POS both set to 0 on a delta.
(On my Folger Kossel, the Z home is about 254 . . . fwiw . . . although from the Config you posted earlier, that should be where you are set . . . you are using the *MAX* end

Did you home with G28 first? If not, it won't know where it is starting. If Z=0 is not tip on the bed, you need to adjust the value in the Configuration.h until it does. Then G1 Z50 F4000 should put you at 50mm . . .

You have to uncomment the line in Marlin's Configuration.h file for that device, as well as tell the Arduino toolkit to include u8glib. Recompile and download to your Mega, and it should work.

Hmmm . . . on my Folger Kossel, I have had no problems at all with PLA, other than needing to run a much higher drive to the extruder motor (they say .55 IIRC, .85 actually works . . .). I have run almost a full spool with zero issues, so I have a hard time believing that thier extruder is inherently bad for PLA, unless tolerance of the parts is that bad . . .

I posted a link to an upgraded part recently - if you search my posts, it should come up. I ditched the connectors and went to Euroblock terminal strips . . . just about as easy to connect/disconnect, but with no spliding/spring contacts to fail. In any case, they are 5mm pitch Molex Euroblock, and all the styles are stocked at Mouser Electronics - www.mouser.com.

Regarding the end stops, basically you set the distance by moving the head as close to the tower as you can get, and adjusting the end stop such that Z=0 is at the bed surface at all three towers (the end stop on a tower really only effects the height at that tower) after a G28 home and reposition. Once all three towers match, you check the center, and adjust the delta geometry settings such that

Hello, Overall very happy with this kit.
The build manual and configuration manuals were a big help.
But only get you 90% of the way done.

The first shows how the extruder head moves back and forth in the x-direction.

Check your power connectors on the RAMPS for melting. The cheap Chinese knockoff of a Molex connector used on these fail well below what the part should handle, is a common problem, and is consistent with your description of "did not work until I unplugged and replugged all the wires . . . "

It sounds like either bad IO on the Arduino, or somehow your pins.h file got knackered, and the drive signal is not getting to the right pins. I suppose a defective RAMPS with some bad traces could do this as well, but to hit two separate functions the same is unlikely. You do have the RAMPs and Arduino fully seated onto each other, and no bent pins, right?

It's the probe Z offset value in the Configuration.h file . . .
Home the printer with G28, and the probe should be on the bed at Z=0. Raise the head, deploy the probe, and lower until it activates. Do this a couple of times to get a repeatable number. That number is what goes into the config file, so that both the tip and the probe agree on where Z=0 is . . .
