Biqu B1 - Not heating the hotend
(sh.itjust.works)
Hi
A couple of days ago the hotend wouldn't heat up and i got a couple of errorcodes/warnings in the display. The bed heats up just fine, so i ordered a new hotend parts (heater, thermistor and a new aluminum block). Changed all of this, but still the same error. I can se that the thermistor works because it changes values in the display when touching the thermistor-end. Any good ideas why the heater doesn't heat?
You've added another notch to you nerd belt!
That's the exact setup I've got. Let me know if you have any questions or issues getting things set up. Once you have it figured out you'll wonder why anyone uses marlin.. there's just so much available. With marlin, literally everything is baked directly into the firmware, and unless you compiled it yourself or dug through the code you've got no idea what's going on with the printer. Set up a retraction tower? Better hope it was set up right because marlin won't tell you current retract settings. Leveled your bed? Better hope that the numbers stick and the mesh is actually applied to prints.
With Klipper, not only is all of that easily configurable by editing a text file, all of that information is available directly in the GUI. Want your printer to do something else at the start of every print? Just change your start up macro. Realize that you set the wrong retract distance in your slicer? Just change the setting in the GUI. Start a print job with 5 models and one of them starts to fail? Don't cancel the whole print, just the part that's failing.
These are just off the top of my head improvements and there's literally dozens if not hundreds more. What have you done? You've elevated.
I only have questions.
First things first, i probably should get control on the cables and their markings before i take out the old mainboard.
I'll start this adventure as soon as the parts arrive. Parts are still in the mail somewhere..
Thanks for offering to help me out here.
