Topic: Heat extrude Failure.

4 days ago my printer gave me a 011 Error.

Symptoms:
1. Temperature sensor wont go past 32-33 Degrees Celsius.


What I've done per the advice for other forum posts:

  • I placed a small open flame on to the tip of the extruder, the temperature goes up on the LCD and the small fan cuts on.

  • I've read the forums about replacing the bad connectors. I have done that and still the temperature is not going up,

XYZ if their new cable does not work the only other option I can think of is to have them send me another heating unit. The printer is only 20 Days old

Re: Heat extrude Failure.

The 011 error means the heat block did not reach temp in a preset amount of time. This means that if your thermistor is responding as you proved it is by using another heat source, then your heater is not heating. That could be due to a dead heater, a bad connection which is very common in the harness above the extruder. Or your heating circuit on the main board is blown. If you have a multimeter you could measure to see if the heater is getting power by disconnection the two pin harness above the extruder and measuring for 12 volts on the machine side of that harness.

Carl,

I will give the multimeter a try.

What I forgot to mention as well is, I took the heating unit out and did put 12 volts across the 2  wires with alligator clips the unit did begin to heat up.

So I am kind of stumped. I've already voided the warranty (should have waited for their new cable to come in first) My only other option would be to purchase another heating unit which sucks, cause its hasn't been 90 days yet...


I'll report my findings, thanks for your help.

Re: Heat extrude Failure.

Heater cartridges are on amazon dirt cheap. Just weld the new heater to the existing wire on the davinci and it will work fine.

I found this on Amazon, but it goes inside of the head of the "extrusion head"  can the existing one be pulled out? Also I don't think my issue is a heating issue, because when i put 12v directly on the leads the head gets hot. I am going to test the control board as carl suggested to see if 12v is coming into the board.

There should be a fuse, looks like a surface mount resistor near the 12 volt connection on the board. That is actually a zero ohm resistor used as a fuse and often gets blown by using the brass brush while the heater is on. Check to see if it appears to be burnt, if not measure with your meter on resistance and see if it is less than 5 ohms. If not it will need to be replaced.

Carl_m1968 Is this a surface mount resistor on the back of the printer or on the extruder itself? the voltage coming into the heating element from the printer measures 1v. by the way. not 12 as i would expect.

It is a surface mount resistor on the main board in the back of the printer. Should be near the 12 volt input. White connector with two yellow and two black wires.

You should get a multimeter that can measure resistance.  The thre marked 000 should each measure no more than 10 ohms allowing for meter leads. If one or more measures higher it shoulf be replaced. They don't always visibly burn.

The other measurement to take ising the meter on dc volts is to connect one lead of the meter to ground (one of the black wires). Then the other meter lead to the left side of tha small white coonector in the bottom of your picture while the hot end should be heating. Make sure to make contact with the metal part of the connector pin inside the white housings. You should see 12 volts there.

Also when you measure resistance of those resistors make sure power is off.

Re: Heat extrude Failure.

So after waiting nearly a week and a half for my extruder. These guys sent me the WRONG heating cable.

how would i test the resistance of a resistor?

Re: Heat extrude Failure.

You set the meter to measure resistance . Then put one lead on each side of the resistor. Your meter should show a resistance of 5 ohms or less. If higher the resistor is bad or you are measuring the wrong one.

ok i got that figured out, but which specific resistors do i test?

Post of good picture of the left end of your board from about middle over and I will try to point out the ones that can be an issue.

I just wanted to add what I found on my 1.0a.  I just picked this printer up with the same error.  I checked the connectors and they seem to have a good solid connection.  I started probing around on the main board and found that the resistor was in fact open on the heating circuit.  If you look at the picture you posted, it is the 2 pin white connector on the bottom left of the board.  The board is silk screened "E1 Heater".  Just about that is R271, which should be a 1 ohm resistor.  (there is another 1 ohm just above that labeled R56 that you can use to test your meter.  They both should read the same resistance).  I have some of these on order since I could not find any on my scavenged boards. 

I may have some 1/4w resistors I can tack on there for now to see if the fix works.  I will let you know.
