@nylkos the e3d documentation mentions using quite light force to tighten the nozzle:

Ant this might be useful as well:

Perfect,
Thanks to both of you, have a great day!

@nylkos said in Can a short from the heater wires damage the board?:

Apparently there was a contact between the wires and my printer doesn't connect anymore (web control).

Is my board finished or is there some hope?

When power is applied, does the green 3.3V LED light up? Does anything on the board get hot?

The heatsink fans supplied by E3D do not work with PWM, so you will have to be content with turning them on and off.

See section"Setting up the tool change files" at https://miscsolutions.wordpress.com/2014/07/27/converting-the-reprappro-ormerod-to-dual-colour/#more-320.

I can't seem to make it work properly so I am taking a look at their .pp (Gcode source)

It's too complex for me ATM but I was hoping to get it done and save it after once it works properly.

I seriously hope some one might help me with this.

Thanks you for your help

The laser doesn't have a TTL, it's an old highschool project, a black paper burner / match lighter I made with a laser diode from an old CD burner, I had built a Step down 12V to 5V.

I think that the simplest thing should be to build a new Step down for 24V to 5V and replace the older one.

Thank you for you assistance.

I printed the one that Phaedrux linked, it works OK as long as you arent using dual extrusion.

It's ok to unplug a thermistor with the board turned on as long as you are careful not to short anything.

Bridging success with PLA depends much more on having a good print cooling setup than it does on temperature. If your prints are ok apart from bridging then there is probably nothing wrong with your printing temperature. To check the temperature using a thermocouple, feed the thermocouple into the hot end where the filament would normally go.

I hadn't read that one yet, thanks you for all the information.

Will do thanks you

I would have the fan at the top of the enclosure with a flap over it. Fan connected to duct running outside. Place the filter on the bottom with a flap on top of it as well. The filter flap needing the best seal to keep any fumes from leaking by it. When done printing, kick on the fan. It will pull open the filter flap and push open the fan flap exhausting all of the fumes outside.

Thank you for the suggestion, will do the testing, I actually have a PID controller with a K-type Thermocouple probe for a different project.

Very important! Check that if you disconnect the thermistors, the temperature in the web interface reads as error. If instead it reads a very low temperature, reduce the H parameters until it does report error, then reduce them a bit more.

How much of an issue is it IF I can't bring error while trying the Very important check above?

Here is My M307:

M307 H1 A21.5 C244.3 D5.6 B0

The speed didn't really help… now I keep getting

Error: heating fault on heater 1, temperature excursion exceeded 15.0C

&

Error: heating fault on heater 1, temperature rising much more slowly than the expected 0.0°C/sec

I believe that it could be noise… is it normal that the values keep changing even after the fault?

How do we fix that issue?
Is there specific wires that can protect from that?

Is there a way for a fault to cause a pause?

For PETG printing that could help saving on material, low warping so the pause shouldn't be an issue... a code that we could input at the beginning of each print that would cause a pause until cancelled or until the heater is back at the correct temperature and then continues the print

My house and (or) board are (is) seriously haunted…
I restarted my printer and now it seems to be working perfectly...

I have no idea from where the movement was, but I reinstalled the config files and now it's not there anymore
