Problem with hotend. #41
Comments

It's possible that it has a short. Have you checked the connection with a mutimeter? |

I have a multimeter but what do I check? Thanks for your response.

Check for continuity on both ends of the wires and the voltage on the controller board versus the voltage going into the hotend.

Joshua Rising I am preparing to go to my friend's chalet till Saturday so I will get into this when I get back if you are still so kind. Thank you.

Run a PID calibration.

Your software need to know how to handle the new hot end.

about a day and then started to behave strangely. When I preheated the
nozzle to 250 degrees C which it could always do very quickly I noticed
that it was pooping out at 184 C and then will eventually go up to 195 and
flutter down and up from there. I keep trying things like checking the
thermistor and it’s easy to check the heater. Everything is plugged in all
right. It was working now it’s not. Is it something to do with the computer
program? I have version 1.1.6 Marlin firmware. I noticed I can set it to
190 C and it will go there and stay there with it’s up and down a few
degrees. It just can’t get up to what I want.

Attach an incandescent bulb rated for the voltage you are monitoring (ie: 12v bulb for 12v system. 24v bulb for 24v system. etc.) to the heater leads in parallel with the heater. If temps drop while the bulb stays lit, suspect heater. If bulb goes out AND temps drop, suspect control hardware (thermistor, connections, wires). If all of that looks fine, check the control board itself REAL carefully. Look for broken or dull solder connections, or overheating components. Good idea to reset the Ender 3 to factory defaults first. |

I have my ender 3 pro connected to my macbook pro with Marlin 1.6.1 installed and my new usb cable and cannot seem to tether it even with printrun for mac installed. I would like to run the PID setup but my mac can't find the ender. Should I try octoprint? A slicer? |
|
I made an error I have a Creality 1.1.6 board. I'm not sure what version of Marlin is installed. I don't know what it wants for a "port". I tried com2 and usb2 and variations, but have no results, just errors. |

I have the bootloader installed(flashed) in my ender 3 pro and I have the printer connected to my macbook pro. Using Printrun for mac the nozzle temperature to 250 C and at about 190 C it failed. This is the error message in Printrun. Setting hotend temperature to 250.000000 degrees Celsius. Error:Heating failed, Heating failed Printer halted please reset. I don't even know if I should try to set the PID at 190 or what? |

Hi @roon4660, is this issue ongoing or can we close it out? |
