LCD Screen, BLTouch, and Thermistors

by Nhcraig01

So the other day I was dissembling my 3d printer to work on the hot end. After putting it back together I turned the printer on I came across some weird anomalies.

  1. The boot up screen showing the version of marlin took longer than normal to go away.
  2. The temperatures displayed for the bed and nozzle would drop about 5ish degrees randomly, when idle.
  3. When I run the auto bed leveling feature the LCD screen will flicker when the BLTouch is triggered.
    From what I can tell it will still print fine, though I have not gone through a full print. Any idea to what may have caused this or how to fix this would be greatly appreciated.

Thank You,

Whats wrong wiht my math? Stepper tuening

by divreig

So got a new build trying to tune my stepper motors . i have A4988 drivers. I am using the formula Vref = I_TripMax 8 Rs. yet it does not move and if increase voltage I get missing steps.

I have a motor with 1.5A, and resistor on the board is r100 rating so my math is : 1.5 x .7 x 8 x. 01 =0.084.

Extruder Motor

by will4742

I have Hictop 3DP-17 I love the quality but right now I am having trouble with the extruder motor. The motor will just sit and oscillate without advancing the filament.
I have checked the cable, the software, the voltage and recently I have replaced the motor itself. The new Motor just does the same thing the old motor did. To add in a little confusion If I switch the cable over to the X-axis motor the X-Axis motor works fine but the Extruder motor will still not function on the X-Axis controller. Any Ideas out there about what I can check?

Octoprint yawcam and windows vista

by harddrv1

Anyone using octoprint on windows vista? i cant get camera to work with octoprint running on windows vista. Settings keep reverting to the default. How can I switch the settings tried both in octoprint and manually changing the config.yaml? When I right click broken link icon where video should be it always says 127.1.1 or w/e it is, no matter what I set config.yaml or settings too? Anyone know how to make it stay at my local ip?

Inconsistent filament flow

by shillicious

I'm having print problems and have no idea where to go from here. I've tried different filaments, different temperatures. I've tried adjusting the tension on the extruder. I would greatly appreciate tips on what to try next. The attached video doesn't show it in great detail, but you can see that in some areas, the flow seems nearly perfect, then it will skip, then it will turn into a blob.
