I noticed that on the wiki the Reflist (list of references) template is no longer working. It have not been modified and is a copy of the original Wikimedia template minus the documentation ref which is not implemented on reprap wiki. I don't know when it ceased to work and I have not seen other template failure. It is a relatively complex template and I don't understand why it fails.

So, no comments ? Anyway, I updated my schematic : - Added enclosure, its earthing and metal connectors earthing - Added recommendation for a thermal fuse (could be a thermal switch either), though bad installation may cause more harm than good, but this is normal practice for heating equipment from decades. - Recommend a screw terminal on bed support to change cable type (if needed) for movingby PRZ - Safety & Best Practices
Hello, With the advent of larger printers, we see more people willing to installed AC heat beds, notably for CoreXY and ‘Ultimaker type’ printers. This is fairly more critical than on Delta printers with fixed bed, and the question come regularly on the forums. I also intend to do so on a CoreXY with a bed 400x400. Most people don’t quite capture all the safety concerns such installation may cauby PRZ - Safety & Best Practices
On the 3D printer Tevo ‘Tornado’, a clone of the Creality CR-10, the bed is powered directly by the mains AC ,110/230V. The high power of such bed is appealing but: The Tevo Tornado are printers with a Y moving bed, so bed power supply cables are submitted to intense stress and it is unavoidable that cables break or detach. Indeed, the CR-10 is notorious for the break of its bed cables, notablyby PRZ - Safety & Best Practices
La commande M666 est faite pour que les fins de courses soit tous a la même distance du lit. On ne cherche pas a centrer la tête, ça ne sert à rien.

En principe, échanger deux des connecteurs doit inverser le sens du X ou du Y, c'est une erreur que j'avais eu sur la Fisher delta car il y avait une erreur sur le manuel. Donc échanger le X et le Y est bien la solution. Par contre, il faut respecter le sens de rotation et bien vérifier que quand on demande a une colonne de monter, elle monte au lieu de descendre (vérifier en faisant le homing -by PRZ - RepRap Groupe d'Utilisateurs Francophone
Le problème est connu depuis que cette imprimante est sortie et il a fait l’objet de nombreux commentaires et même vidéos sur Youtube, mais en anglais – et en italien -. Le lit est prévu pour 24V et il est alimenté en 12V, ce qui ne peut pas fonctionner. C’était évident dès la lecture de la fiche technique.

You can find M1 (difficultly flamable) PVC foam panels. That is an interesting solution as quite light. About oxygen depletion in an enclosure, the problem is that a rapid fire in a tight enclosure will increase the pressure and may blow off the door, defeating the purpose. It occured to me twice in a domestic microwave oven and I can tell that I was quite surprised by the event. For general saby PRZ - Safety & Best Practices
There is no problem to have multiple users behind one power chord. About fuses, the cable protection is the MAXIMUM rating of a fuse, but it may be safer to use a lower rate near the effectively used power. You just shall take into account that power supplies have a significant inrush current at startup and that using slow blow fuse may be needed. Another point is that a power switch cannot be tby PRZ - Safety & Best Practices

I got yesterday a very troubling incident. I have two printers, the big one equipped with a physical emergency shutdown (ESD) switch (red mushroom button), the other smaller one NOT equipped with an ESD.

It is important to note that the only purpose to install an external 5V supply was to be compliant with european EMC regulation, as the on-board regulator was emitting too much EMC. Most people don't care a lot about that, and it seems the on-board emission is not sufficiently high to creates troubles in your environment (no problem with TV, radio or other electronic). It is wise anyway to shielby PRZ - Duet

Yes, just note that an ATX power supply is powered ON when this output is pulled to Ground, so this pin shall be connected to the negative pin of your relay command. You can activate in DWC the command of the power supply. See this topic : which also refer to former topics.by PRZ - Duet
I set in bold here the pins accessibles by M42 : From the table, on Duet 0.8.5, the digital pin 66 is not accessible on expansion connector. The AD13 as indicated in the G-code page correspond in fact to the digital pin 65. On Duet 0.6, digital pin 66 is PB15 (connector pin 31)by PRZ - Duet
On schematic, PB16 D67 is pin 32, not 34. What I think (I am not involved in the firmware, but I already tracked pins with difficulties to get them) is that internally in the firmware, the pins have the same numbers as the arduino digital pins, probably because they started to write firmware with Arduino Library. And this was probably also difficult for programmer, as this is Dan Newman who creaby PRZ - Duet
Yes, there is thermal shutdown in the drivers. The recovery can be quite fast (say, a fraction of a second), so this can cause intermittent working and that is difficult to diagnose. But you don't have loss on three steppers, probably only one. Shifting occur when you loose step on one column only. You could do much more than 1000 mA, and considering the size of your machine 1350 to 1400 mA migby PRZ - Duet
Pinout of the expansion connector is defined here : Note that pin names refer to the Arduino Due pin naming, which may sometimes help. here Arduino Due pins schematic. The ref are the gray one : Duet do have pins which don't exists on Arduino Due, hence the 'X' pins. Note there are a few differences between Duet 0.6 and Duet 0.8.5. Duet WiFi is another story.by PRZ - Duet
So, what you have is shifting layers? Have a look to this page : This thread is also interesting, even if I think your problem is different : Considering the size of your printer, you may have the belt jumping on teeth. Your belt shall be well tensioned. But not too much. Excessive tension can also cause step loss. Check if the belt is not rubbing on pulley flanges and that your stepper is wby PRZ - Duet
This is a relatively large machine, with weights on the heavy side, but your parameters looks workable, accelerations and speed being quite low. What is the weight of one arm ? You have 20 teeth pulleys, using 16 teeth may help a bit. For that printer size, larger belts (9mm) may increase stiffness.

Closed loop steppers for a printer is something extremely rare. This is something desirable for a router, but the loads on a printer are fairly low and with good parameters, you may never loose a step.

Out of curiosity, I tested R/C servo operation with a controlled fan output. Good news, it works ! The command M106 exists and allow frequency control, so everything was available.
