Re: Thermal Runaway - 9 years ago
After looking more closely at the extruder, I realized the heater block was against the heat sink, and the nozzle too far out. I fixed this and replaced the thermistor. The past 3 prints have had no problems, very little fluctuation in temperature.by fusa - Prusa i3 and variants
Re: Thermal Runaway - 10 years ago
Yes it does have those fuses. If I do replace them which ones should I get? Thanks for your reply. I just took a temperature reading on the fuses using an infra red thermometer. They are 90-96F after printing for 4 hours.by fusa - Prusa i3 and variants
Thermal Runaway - 10 years ago
I have been having problems with thermal runaways. It usually happens when the extruder is heating, but sometimes when the bed is heating. It happens usually during the first few minutes, but sometimes after a few hours. i have tried replacing the power supply. I also tried pid tuning. Anyone have any ideas what could cause this? Attached is a screenshot of a short print.by fusa - Prusa i3 and variants
Re: USB disconnects - 10 years ago
I am using RAMPS 1.4 connected to iduino Mega 256 Arduino clone control board. I bought a RepRap RAMPS 1.4 12864 LCD Display 3D Printer Controller with Adapter to print from SD card. But when I print from SD the printer acts erratically. It will print normal then go far to X or Y axis. It doesnt do this when I print from USB (just random disconnections). I have tried 3 different USB cables,by fusa - Prusa i3 and variants
USB disconnects - 10 years ago
I finished building my Prusa i3 and have it printing. But I am having issues with USB disconnecting my my computer. The only way to reestablish a connection is if I unplug the USB cable and plug it back in. I have tried a different USB cable and different port. I still have the random disconnects. Sometimes it will disconnect after a few minutes, sometimes an hour or more. It happens when Iby fusa - Prusa i3 and variants
