@davidalone

I need to purchase this part as well for my printer. Can you tell me what you ordered?

Thanks,

This machine uses photo sensors on all of it's axis as you said. However they do not react to magnets. That would be a hall sensor. What happens in this machine is that the photo sensor is a U shaped device. On one side is and IR LED. On the other is a photo transistor. As long as the beam of light (IR so it's invisible) is allowed to shine across the device to the photo transistor it will conduct current through the transistor like a switch that is on. If the beam of light is broken such as is the case in our machines by a plastic part that slides into the U shape then the photo transistor stops conducting like a switch that has been turned off. Now depending on the type of devices our machines have they could do the reverse and conduct when blocked and not conduct when unblocked.

However there are no hall sensors (they react to magnets) in our machines and thus no magnets either.

What it sounds like to me is that the left side of the Y carriage is hitting the back of the machine before the right side where the sensor and home is. So it sits there skipping and eventually times out and throws up the error code. I would suggest for the op to do what the previous poster said. Pull the carriage all the way forward and see if both sides hit the X pulley on each side at the same time. If not then forcefully pull the side not meeting the pulley to force it to skip a notch or two on the belt. You can do same thing by pushing it all the way back on both sides till it won't move further. Again with force as you want to make it jump a notch or two on the gear. Depending on how far it has skipped. I had to do this on mine once as it was trying to home and got stuck on a plate that was set too high. Made the left side of the Y carriage skip a few notches.

When I first got my printer, it did the same thing, right out of the box. What it was was that the Y axis was not perfectlly aligned, like as someone had said earlier, it just "jumped" I contacted XYZ, and they provided me a solution. Manually pull (With the machine off) the extruder all the way to the front of the printer, and take a look at where the black plastic meets the white gears. It should barely touch on both sides, but I would guess on those peoples machines it doesn't touch on both sides. XYZ's solution, pull it, by force, back into place. Yes, literally, pull the side that isn't touching forward by force and make it jump a segment. That solved my issue.

I got it. The endstop I ordered off line worked great. Had to cut up the mount for the sensor mount but it works just the same. I have printed 3 things with it and no problems.

I'd guess that the other end stops are the same make and model. I will pull the other one off tomorrow and see if I can't find one Thanks.

At the price point of this printer, I'd be shocked if the sensor is anything but a commodity part.
Me thinks we should be able to locate a part number and find a comparable optical interrupt sensor from Digikey or even eBay.

If you have the sensor liberated from the printer, can you post pictures of it?
Even without a part number I imagine we can find a replacement without paying the XYZ tax.

Having a similiar issue, but I think it's because the belts are too loose to move the Y axis. I can't seem to access the hex screw to tighten them. Any tips on doing this? (the printer just clicks LOUDLY when trying to calibrate, even in jog mode)

That's what I ask them. Now they say that I can buy it but for 24 dollars.

Why do they care where you bought it? They got their money for it.

I'm looking for the y axis sensor for the da vinci 1.0. I contacted xyz and they said that they wouldn't sell it to me because I bought it used off ebay. Anyone know where I can get one. Thanks david

Just watched a video over at voltivo "cracked-y-axis-bearing-holder" wherein during a bearing holder replacement the two y axis belts came out of alignment. Ie one belt slipped during the repair. The result was the sensor didn't get triggered before the other side hit the back end. So its possible your only a notch off, if you were able to put something behind the sensor to get it to work. Watch the video its right after he puts it back together. But it could be a simple belt adjustment.

Those are standard optical (not magnetic) end-stops on the davinci. Other printers sometimes use mechanical end-stops. But optical are more accurate. The way they work is one side of the horseshoe is a small led the other is a photo sensor. Its triggered when something goes in the gap and blocks the light. It sounds like If the sensor is out of alignment it may not be getting deep enough in the gap to block the light path.

Hi there. I'm getting the same problem on my 3 day old printer. All fine, finishes a job, change the cartridge, go to start the next job, and boom. 0031. The Magnet thing didn't fix it, and attempting to push it back into place worked for about 6 seconds. Help?

It is just a thin piece of plastic on the carriage (the part that has the bushings and rides on the rail...) that goes into the sensor - the way I solved my 0031 issue was to take the two torx size 10 screws holding the sensor housing (the white plastic part) - pop the sensor (the black part) out of the housing, it just clips into place - then I folded up a piece of tin foil (paper would probably be a better choice - less chance of a short) and put it behind the sensor to move it out a little bit, and only attached it back into the white plastic housing by the bottom clip... you can check if it is plugged in good when you do this too. Then I reinstalled the sensor and housing and it worked! Not very scientific, but after that fix I have managed to print out both the demo key chain and star vase and spent what seemed like a couple of hours calibrating the base - it only threw the 0031 code once, so I repeated the adjustment on the sensor and it ran fine... makes me think I one of my first new designs should be a better sensor holder...

not certain it will work for you, but here is hoping - oh, and if you haven't done it already, popping the plastic side panel off is easy, you just work a flat blade screwdriver under the edge (I start at the front) until it lifts over the catch - there's about six of them you have to release, then it just lifts off...

look at me, an XZY owner for less than a week and already giving advice
