No Problem
But to be honest i’m a 13 yr old with a Da Vinci 1.0 and I was able to flash it with minimal problems. But I can understand why you might wanna stay clear.

I’ve been running some big prints using the DaVinci filament after changing back from the non-davinci stuff I bought, and they’re coming out as expected, so I’m not sure what’s going wrong for you. At a guess, it sounds like it could be that you need to tweak your z-axis setting a little. I’m told that this z-axis tweaking is a fairly regular thing. Also, on one of my very first prints I did when I first got my printer, the filament clogged up the outside of the nozzle behind the silver plate, and I just couldn’t get a good print. It was only after I removed the plate that I could see how much filament was clogged up behind it. I cleaned big lumps of it out and instantly got better quality results. I’m not sure if this is helpful to you.

Thank you so much for your reply. I appreciate it. I indeed tweaked my Z-axis. I moved it up abit and indeed the clicking is way less. I also removed the plate. There was nothing clogged but the extruder head was a but dirty/smudges so i cleaned it off.
I tested a print. Its started out fine. But after an hour my print got brittle. See attachment. You can clearly see where it starts to go wrong. I am just getting tired now. I have tried so many things i dont know what to do anymore…siigh
I had a random thought for this. I’ve been looking at the printer, and trying to determine where it measures the filament. If it’s at the feeder…ugh, but if it’s at the coil itself, wouldn’t it be possible to spoof it simply by locking a nearly empty roll in place, and just feed from an external roll looped around the empty and into the feed? Idk, I’m waiting for my new filament to show and I’ll see if it works.

What I noticed in my da Vinci 1.0 is that the printer doesn’t seam like it measures filament use, I think it calculates the usage in the slicer and basically subtracts it from the cartridges chip memory. There is an optical sensor in the extruder but I don’t think that it would be able to measure the use because the filament is always one color through out. I’m not sure if this is different in the da Vinci junior but it would be interesting to see how the printer does that. I’ll look into it more soon.
Hmm,.that could be, but how would it cope with a cancelled print if things went bad? Still deduct the filament even though it wasn’t all used? That would be unfortunate. Looking at the build, I can see 4 wires going to the feeder assembly. It may have a micro counter there which keeps track, and then writes back to the chip… Which sounds pretty feasible… Ugh… Well, its just a starter printer until I get better stuff down the road. Getting pretty decent prints off of it at least

You make a very good point. I didn’t even think about that. Hopefully someone figures out how to replace the firmware or how to trick the cartridge chip. They have some great people on the solid forum site working on it. Hopefully they will figure out something soon.
Yup, after doing some fiddling about, and ending a couple of prints, it looks like its measuring the amount of filament run through the feeder mechanism, probably as a measure per rotation setup, and then deducts it back from the chip until you hit zero. As long as there is a chip, that hasn’t hit zero, I’m pretty sure that you can run whatever through, but the chip has to be in location above its reader/writer . if the chip isn’t there, and it goes to write to it, bam, no more print, and you get a spool error. And the job gets cancelled . so its going to have to be some sort of spoof, sacrificial roll of filament, or software hack to be able to use other filament.

Maybe there is a way to trick the measuring mechanism. There is a small chance that it only uses it to measure the amount of filament being used and not for if filament is actually being moved through. Small chance, but it may be worth looking into. If that doesn’t work, easy solution thrown out the window. Other options are, faking the cartridge chip with an RFID tag, completely rewriting the firmware to the printer, or resetting the cartridges chips. Hopefully one of these are figured out soon. I’m hoping for the firmware rewrite. Due to the nature of XYZ’s software.
That sadly does no good on a davinci Jr. Due to the way they’re chippd, won’t work.
I saw this video on youtube where a guy bought clear pla and sprayed painted it different colors

For the Da Vinci Jr the filament card says i have ran out of filament but i can still see there being a good amount still on the spool is there a way to fix this if so please help?
According to xyz, when I asked about it on mine, they incorporate extra filament for loading and for the little test strips it prints down one side before the main print. I’ve got 3 rolls of “empty” with varying amounts of filament left due to this
Ohh ok thank you appreciate the help.
I am pretty sure that you can buy a spool of filament with the chip, unravel the xyz pla then put on your own. Since the PLA will melt at the same temperature, it should still print equally. As long as it is the same diameter it should work. The xyz printer uses the chip to detect how much filament and what type of filament is being used. I dont think the jr has an optical sensor. Maybe this is worth a try…
You don’t have to re-spool the new filament. Just leave the old spool (with the chip in place) and feed directly into the feeder. I leave my new spool on the floor - although I could build a custom holder. As long as the filament feeds from below and moves easily - no problem.
Does this really work Andrew? Thinking about buying a da vinci mini but only be alle to use the XYZPRINTING filament is holding me back a bit.
You do need the chip. So you do need to buy the filament from them. However I am current running with the white chip holder on the spool holder and my required filament feeding from a spool on the floor.
Not ideal - but…
I would like to know why there are wires leading to the spool holder - cus if that is where the RFID piece - maybe it can be spoofed on the spool holder itself.
