Aww, shit... These PTFE lined tubes are fragile! Broke the throat when tightening it. -> to eBays! again... This time maybe few more tubes?by Veesta - Plastic Extruder Working Group
Turn ON the the bed and measure the voltage starting from PSU to RAMPS to heatbed pins in RAMPS and all the way to the heated bed while it is warming up. (Is the red led lit on the heat bed?) PSU to RAMPS should be 12V From RAMPS pins to bed should be at least 10V Possible failed parts on RAMPS, polyfuse, bed mosfet, maybe burnt wires?by Veesta - Prusa i3 and variants
About 230°C, that is good to know. So, PTFE prevents this form happening? And even if it does, it might still push through? I have some problems printing. A large surface infills nicely, but small details like screw holes and thin walls might stop extruding -> it will grind into the filament. And once i pull the filament out, the tip looks like that. The tip is melted and thicker. (On succby Veesta - Plastic Extruder Working Group
Hi there, Yup, dumb question but i'm interested. My PTFE throat just arrived and i have two metal throats in the box. What is the benefit for using PTFE instead of metal? Also, which end is the nozzle? The open PTFE end or the closed metal end? I'd guess the open PTFE end should be facing the nozzle? My extruder is the MK8 thingy, which currently has a metal throat from E3D V6 with a heatby Veesta - Plastic Extruder Working Group
Sending m119 will tell you how your endstops are. If endstop is configured wrong, your axis will not move. Also you need to tell the firmware which endstop it is. MIN or MAX and which way is the home, MIN or MAX. I'd recommend using Pronterface, as it displays debug data from the printer. Not sure if repetier shows it. Also, have you done Vref calibration from the stepper driver potentiometers?by Veesta - Prusa i3 and variants
Lowering the nozzle temp to almost minimum the plastic even flows out and making only the outer perimeter slightly wider solved the fugly layers-not-adhering problem. Printed the same part 9 times and finally got it.by Veesta - Prusa i3 and variants
This is based on your first layer settings and the physical distance between the nozzle and the bed. (assuming 0.1 for the bed) So, 0.35 + 0.1 = 0.45 for the first layer. This is the reason you can adjust your first layer thickness in the Slic3r. The first layer setting is not the same as the real layer thickness. By default, Slic3r has 200% extrusion for the first layer, so it will be twiceby Veesta - Prusa i3 and variants
Can you edit your firmware? First you do is tune down your acceleration values to 1000. (or lower) Why this jam happens? There is one reason and it happens in two different ways. First reason is that your extruder is not able to push the filament out as fast as it should. This means you are trying to extrude unmelted (raw filament) filament and you end up grinding the filament and ruining theby Veesta - Prusa i3 and variants

I don't know about the layers, but Infill looks nice when printing. Maybe i should make the perimeters, say 10% fatter? IIRC, those perimeters are printed 60mm/s inner and 40mm/s outer. Cooling fan is always on, atleast 35% I'm beginning to think i have some kind of physical damage in the nozzle tip. (combined with ringing from the backlash of mechanical parts) This damage would make the plasticby Veesta - Prusa i3 and variants
Try reducing the Vref on the hot steppers. Also add cooling fan to your stepper drivers. I have 1V on Z axis motors and they run at "room temperature" or lukewarm. If your stepper driver gets too hot, it will shutdown for a moment and during that time it will lose steps. I noticed this when i had too much current in the steppers and they were running hot. They eventually lost their position. Hoby Veesta - Prusa i3 and variants
Pronterface would be more helpful to diagnose this. Move your axis from pronterface and look what it says on the right hand column. It might say "endstop hit" so it will not move at all. Sending m119 will report back the status of the endstops. If you see that it is not touching the endstop, you might need to revert the endstop logic from the marlin configuration.h Also notice that the endstopby Veesta - Prusa i3 and variants
First you need to set your board version in configuration.h to the type you have and to the options you want it to have. Heat bed is a firmware option and it needs to be turned on to work.

I would look at the Vref on the steppers first. Then acceleration values on the firmware.by Veesta - Prusa i3 and variants
Do you have fans cooling on your RAMPS? I experienced some issues where the poly-fuses tripped and that caused problems with bed temperature and "THERMAL RUNAWAY" which then triggered an emergency stop of the printer. 40mm fan cooling the fuses solved this problem. And another 40mm fan on the stepper drivers.by Veesta - Prusa i3 and variants
Prusa i3 Rework, as per I've changed the acceleration values and XY jerk and it seems to make a difference. It runs more stable and will not block the nozzle that easily during print. Slight improvement on the print quality. #define DEFAULT_ACCELERATION 1000 // X, Y, Z and E acceleration in mm/s^2 for printing moves #define DEFAULT_RETRACT_ACCELERATION 1000 // E accelerationby Veesta - Prusa i3 and variants
20mm Cube looks like this: You can see the first layer has "saw edges" For some reason my nozzle spits it out like that and it is constant from all the way to top. The "saw edge" continues all the way to the top and in the same position. It is not random. Also there is small banding running in 45 degrees angle through the print.

Hi there, i have RAMPS 1.4 and my heatbed fails. Set heatbed to 70°C and measuring the current from the bed = 10V until it fails somewhere around 60°C to 0.19V.

These are both from the same version. 1.1.0-RC6 Only thing changed is the Configuration.h parameters. Everything else is exactly the same. Can you compile a fresh 1.1.0-RC6 with that Configuration.h using Windows 10 and Arduino IDE 1.6.9 ??by Veesta - Firmware - Marlin
Thank you! Fresh unaltered version of Marlin compiles. Configuration.h fails. When i copy "Configuration.h" from my version and overwrite the fresh. It fails as above.
