If you own a Da Vinci Pro 1.0 you’ve probably ran into the problem that when you open either the top or front door you lose control over the printer. The display will show a warning message that one of the doors is opened instead of the usually displayed progress of the print. This can be very annoying when you are printing with PLA, because if you’re printing with PLA you’ll be wanting to open up both doors of the printer so the PLA model gets cooled as quickly as possible. This thus means losing the display and your controls over the printer, so in this post I’ll be explaining how to bypass this and create a “PLA-mode” for your Da Vinci printer.
If you have browsed the web looking for solutions to resolve this problem, most of the time you’ll be advised to just tape down the switches but I wanted a less ghetto and a more permanent solution. This is why I’ll be adding a switch to the side of the printer which if turned on will send a signal to your printer making it believe its doors are closed while they are in fact open. If this switch is turned of, your printer reacts to open doors just like it did before implementing the extra switch.
What you’ll need:
- Some wire
- A switch with two separate mechanisms (or two switches)
- A soldering iron and some solder
- A drill to make a hole for your switch
- A wire cutter
First of all we are going to locate the wires of the door switches. In general the top door switch uses black wires and can be found in the top left corner of the circuit board. To make sure you have the right wire check it’s label on the circuit board, it should say ‘top_door’. Next we are going to locate the wires of the front door switch, in general these are red and can be found in the bottom right corner of the board. Again check the label on the board to make sure you are holding the correct wires!
Now that we have found the correct wires we can start cutting and soldering. Lets start with the top door, remove the connector from the board and lay the wires before you. We’ll start of by cutting one black wire, where doesn’t really matter as long as you have enough wire left on both ends to re-solder them together. Now strip both ends and grab some of the extra wire (preferably some wire of the same color scheme) and strip one end as well. Now connect the three stripped wires together and solder them to make their connection permanent. Do the same for the other black wire of the top door and be sure to leave enough wire to reach the location where you are going to put your switch. Repeat this step for the front door switch wires!
Normally you should now have four loose wires (two of each color)
and four solder point of each three wires. If not, you did something wrong and you should look for your fault and fix it before continuing. Now we are going to solder those wires to our mechanisms, you shouldn’t solder both circuits of the two switches to the same mechanism as we don’t really know how the circuit board works and connecting those two circuits to one switch mechanism might result into a short circuit and frying your circuit board. Ideally you’ll find a switch on which you can connect two separate mechanisms. If you don’t find this you should use two switches, one for disabling the front door and one for disabling the top door. Now solder each color set of wires to your mechanisms, if you are using switches in which the mechanisms are fixed you should probably first put the switch in place before soldering wires to it (see step four). Make sure your wires our long enough to reach the spot where you are going to fix your switch!
Find a spot where you are going to mount your switch! I used the free space on the side of the printer right above the power switch but any other place you can reach easily will do as well. Find a drill of the appropriate size (according to the size of your switch) and drill your hole where needed. You can now put the switch in place.
Now that your switch is in place you can either connect your mechanisms to your switch or solder your wires to them if you have a mechanism fixed onto your switch. You are now done! Before closing up the printer, make sure you test if everything is working as it should. If you not, you probably forget to solder a wire or a connection might have come loose.
That should be it! Do let me know in the comments if you ran into a problem and I’ll try to help you out. Happy printing!
