Nozzle suddenly stops heating up

by tedward88

Hi all,

I saw someone talking about a similar problem but I thought I'd share mine in a different topic. Yesterday, my Anet was printing as usual (PLA - 190C/60C) and suddenly the nozzle stopped heating up and the extruder motor failed too (both at the same time). I can't tell if the stepper driver for the extruder motor is burnt or it just won't budge because of the <170C nozzle limitation - I heard that Marlin won't let you use the extruder motor if the nozzle is colder than 170C. I will test it as soon as I get home.

I should mention that yesterday morning I added one more part cooling fan to the printer and it did manage to carry out a couple of prints flawlessly. I hooked them up in parallel and they are running at 90% capacity since the nozzle can't really keep up the temp (yes, I did the auto PID). Also, the power supply seemed to be struggling too - it was hot enough that I could barely touch it.

I do have a spare ramps+leonardo which I was going to use for the new printer I am building so I think I will switch to those if there is no other alternative.

Specs: 2 mosfets, stock board, stock power supply, stock bed, e3D V6, 2 part cooling fans, Marlin 1.1.9

Marlin Filament out sensor

by SubaruB4RSK

I think it's supported? I was thinking about getting a filament out for my ramps 1.4 board but I haven't seen too much talked about them.

Bed adhesion on Anet A8

by Florisk6

I recently purchased a Borosilicate glass plate. I used to use painters tape, but I decided it was time to make my life better. Anyhow, after trying to print several first layers I concluded that I had to do something about the adhesion. I thought of a few things:

  1. Using (regular) hairspray
  2. cleaning with isopropyl
  3. buying a BuildTak plate (and if buy this, should I still use the Borosilicate?)

Do you have any suggestions on what I should do?
I print with PLA at a temperature of 200C, and I use a heated bed which is 50C.
