Have you got a fan facing your hotend? Sometimes it makes a cleaner finish. Also did you calibrate marlin, calculate and check the flow of your filament?by brisinger - Reprappers
Nooo! Don't waste the beer. Tesco's el cheapo Everyday Value hairspray does just the trick for me with my heatbed as low as 90C Save the beer for when everything is going wrong and you need something to drown your sorrowsby brisinger - General
Have you made sure the amount the hotend is extruding is calibrated properly? I had that problem a while back and just recalibrated the amount it extrudes in Marlin.by brisinger - Reprappers
Is the thermistor firmly fixed in the hotend? I ended up squirting some spare Arctic silver thermal paste I had in to hold it firmly and give it a constant temperature reading.by brisinger - Reprappers
I didn't faff around with all the stages some tell you to do and it worked out fine. I just made a copy of the original line in Marlin so that I kept a backup in case everything went wrong, then set pronterface extrusion to 50mm. I took off my J-head purely so that I wouldn't be using up filament unnecessarily and it worked for me when I was doing the calculations but you don't need to. Basicallby brisinger - Reprappers
Ah! I've just tried uploading the sprinter firmware and it seems to be working so I guess I'll stick with that for the time being. I've been having problems with marlin at the moment with RAMPS 1.4 so I guess I'm better off sticking with sprinter while I'm setting it up. Probably something silly I did when upgrading the firmware. I've got it running on windoze 7 and pronterface so I'm going to seby brisinger - RAMPS Electronics
I've tested the motors connected to my RAMPS 1.4 and they work fine. When I just connect the thermistors and attach the extruder (D10) and heatbed (D08) there seems to be no power getting to the whatsoever. I've tested it with a meter also and there seems to be nothing registering but the thermistor temperatures are registering in Pronterface. I'm currently using a 400w ATX to power the board.
