Topic: Filament Jam

I just got my duo a week ago and it has been nothing but problems.   I keep getting the error extruder 2 jammed. I am using 2 new OEM cartridges. The extruder itself is not jammed. I swapped the two cartridges and same thing on extruder 2. Extruder 1 prints fine.

I will print for about 1 minute and it gives me the error.  It will keep printing after the error for 20 seconds and then stop the print and the filament is coming out nicely with no clicking.  I was watching the temperature and the extruder 2 never dropped below 209C. 

The print bed only warms up to 70C instead of 90C and it warms up way faster than my AIO.  In fact it warms up faster than the extruders and the leds dim while it is heating.

What does Da Vinci use to sense a fillament Jam?

Inside the head there is the gear on the motor that pushes the filament against the idler. The idler has a black and white pattern on it that is read by an optical sensor on the pcb in the head. If there is a jam the motor would continue to turn but the idler would not since it is the filament that makes it move. I would check for loose wires. Specifically the ribbon that connects to the pcb from the main harness or see if the idler is binded.

Re: Filament Jam

I am having the exact same problem. I don't understand what carl_m1968 is saying to do.

Re: Filament Jam

When you take the extruder assembly out, you will see 4 wheels on a Da Vinci 2.0.  You will notice two are  brass (called the drive gear) and the other two are silver with a painted black and silver pattern (called idler gear).  There are 2 little black sensors labeled u1 and u2 that appear to count the revolutions of the idler gear. 

If I understand correctly the Da Vinci detects if there is a jam by rotating the drive gear which should push the filament down and the filament should spin the idler gear.  If the filament gets jammed then the drive gear will spin put the filament will not move and if the filament does not move then the idler will also not move.  The Da Vinci knows if the motor is spinning the drive gear but the idler gear is not moving then there is a problem.

One of my idler gears looked funny so I was working on swapping the two, but I lost the retaining clip. mad

That would be correct. So either the idler is not turning or thr machine thinks it is not turning because it is not receiving a pulse from the sensor at regular intervals. That could be a bad or loose wire from the circuit board in the head.

Re: Filament Jam

After checking my wiring and my idler gear and finding nothing wrong, I found the solution!  Flashing it with repetier.  It appears the original xyz flash was bad as it would skip steps, heat up to odd temperatures, falsely report jams, and always crash the extruder into the bed. After several hours of tuning and shimming the second extruder 0.016mm, I finaly got good dual filament prints.  Not fun compared to my AIOs that worked perfect out of the boxs.

Thanks for the help.

Re: Filament Jam

Having just got in to 3D printing I bought an AiO last week and was so disappointed with the scanner swapped it for a Duo.  The AiO printed perfectly with zero issues with both ABS and PLA.  This Duo just will not print with PLA.  Continually giving Filament Jam errors on the second or third layer (2 to 3 mins) in to prints.  It's driving me nuts and about to send it back and may buy a Dreamer.  Although wondering whether they all give such issues and I'll end up with the same but for double the money.

Not sure why you would buy a Duo and try to print with PLA? It plainly says on the website and the box that the Duo can only use ABS. The extruder has the same design as the 1.0 it is simply a dual head. Without doing the same heatsinking mods and fan reposition mods as was done on the 1.0, you will not be able to print PLA on a Duo.

If PLA is not mentioned in a printers specs, then I would not just assume it can use PLA. PLA is very different from ABS in how it behaves at premelt temperatures.

How bad was the scanner? I had to stick with the version that came with my printer (1.1.18). When I used a updated version my scans were coming out really bad.

Re: Filament Jam

The scanner is pretty useless. I never got it to have a good scan even using items that should work well.

however I am running my aio on repetier now and am happy with its quality of prints. Looking back on it I wish I had got he 2.0 rather then the aio

Maybe because the 2.0A Duo which I purchased is capable of printing using both ABS and PLA as per the specs on Amazon.  See attach,meant.  The non EU XYZ site only lists the 2.0 Duo NOT the 2.0A which is PLA compatible.

Just found the manufacturer page for the 2.0A which clearly states it IS compatible with BOTH ABS and PLA

http://eu.xyzprinting.com/eu_en/Product/da-Vinci-2.0A

I think one of the contributing factors is the bed is only being heated to 45c when using PLA.  Seems a bit low to me.

Absolutely useless.  Simple figures which conformed to the stated requirements (non-glossy finish, bigger than the size requirement etc) scanned and most looked nothing at all like the original with appendages completely missing etc.  Just awful.

It will work with davinci pla, davinci pla is special in some way.  I have a 1.0a that states compatible with pla, never worked with and normal pla until I modded it.
Also the best bet for pla is the bed heater turned off, use blue tape with glue sick on your bed. 

More than likely you will have to mid your printer to print pla, or return it and buy something more expensive.

You did not specify in your original post you had a 2.0A. The A makes a difference as the A designates the modrl as being compatible with XYZ brand PLA.

This section is for all XYZ printers world wide so please be specific with details.

You also dont normallyprint with PLA on a heated bed. High end Makerbots only print in PLA and they use a cool bed and blue painters tape. Glue stick may or may no be needed depending on the model size.

Re: Filament Jam

Bottom line is that at the end of the day the Davinci line is junk loaded with issues and unless you want to deal with them stay away. Im selling my new one at a loss and still can't move it.

The bottom line is they are cheap machines and will require you to do a bit of work and/or have some technical abilities.  If you want something super simple open your wallet.

I have to agree. They are cheap, but under the hood they are a basic printer like all others. Some corners where cut but once you fix those it is a very syable, reliable, machine that is capable of .1 layers and using most folaments including wood, metal, and so on. Only reason I got rid of mine was space constraints . With my new CTC I can print bigger items in half the space the Da Vinci took up.

In the printer market you also get what you pay for. Dont spend $500 dollars and expect a Makerbot or machine that is plug and play and will work out of the box. I would never expect a sub $700 printer to print out of the box and be problem free.

This entire industry is still young and considered a hobby. A hobby in which you constantly tweak and fiddle with your machine improving it more and more as you go. The price points really only give you an idea of just how much fiddle and tweak your machine will require. Lower price equals naturally more work.
