Hi There,

Once again after a lot of testing I am back.

I fixed a lot of issues on previous posts but not I am having much luck printing...to the point of frustration.

What I have done so far:

I replaced the Titan Extruder with a Bondtech BMG - much of the problems disappear for one or two prints.

On the second print the Bondtech had some sort of stall, and "mushed" the pla filament.. I had to use a hot needle to get it out. In an attempt to try and resolve this I changed from a large bowden set-up mounted on a post to a flying bowden, with a much shorter pipe. Its this that led me to one of three conclusion:

1. Either I have a configuration problem that's effecting the extruder
2. I have a problem with the internals of the hot end either not heating up enough to melt the pla and causing a traffic jam or somehow providing resistance
3. both of the above

Any help will be greatly appreciated.

Best,

Andy

All,

I have been busy trying various thing...one of the problems I found was the heatbreak was not tightened and when hot seemed to unscrew.

I am now going through the config.g and found various issues I have fixed. I did find the attached in the nozzle. A nozzle X no less.

Best,

Andy

Hello everyone,

So I am going through the config.g trying to sort out everything in my other post (Here).

I am getting a strange bed auto calibrate map. Not sure what I have done, I changed the micro stepping from x32 to x16 as it was pointed out to me that x32 does not work. The delta is so smooth now, and according to the callipers moving the right distance.

Please see attached image, I have never seen such a massive curve across the bed. As ever all help extremely appreciated.

Best,

Andy

Eeek no, how hot should it be?

Best,

Andy

Oh boy...so where to begin...

So the extruder after a little persuasion runs a charm, I still have a Bondtech on order but that will be for a second head

I had a fan at the front of the head running full belt...all the time, despite me thinking I had set it to be based on PWM. Either way I was happy to unplig it for now as I have two other fans running either side (which are controlled by PWM...they are currently off).

I took of the silicon sock, and there was plastic everywhere, I decided to do a quick check of my setting with the M303 H1 S250 1. It all went to plan, except there was smoke...very strange. I could not find the source. either way when I used the temp gun...it read at about 10-20 deg c less than the thermistor. After the fourth phase of the tuning i got this message:

**20:20:36
M307 H1
Heater 1 model: gain 456.8, time constant 353.5, dead time 3.3, max PWM 1.00, calibration voltage 24.2, mode PID, inverted no, frequency default
Computed PID parameters for setpoint change: P41.7, I1.217, D96.7
Computed PID parameters for load change: P41.

20:13:55
Warning: Heater 1 appears to be over-powered. If left on at full power, its temperature is predicted to reach 481C.
Auto tune heater 1 completed in 588 sec
Use M307 H1 to see the result, or M500 to save the result in config-override.g**

I then noticed as cleaning of the plastic i could move the head very slightly...I am now waiting for it to cool...either way a much more exciting experiment than I thought I would get

I will dismantle the head and reseat everything, hope I did not damage anything inside the Nozel X

Best,

Andy

I think you might be right, either way I have another extruder and another hot end, so my multiple colour set-up is getting closer

Just don't tell the wife

Best,

Andy

They all seem to rotate fine, no issues. Maybe its temperature or a blockage?

I will investigate, I am not a professional film director but here is some shaky cam footage of the clicking while printing.

Best,

Andy

All,

Thank you all for the replys, I have bought a Bondtech but also a temp gun to see what's happening at the hot end...I don't think its bad bearings as I bought the Titan in Oct 2018...Either way I have been given a lot to think about and try, so I will get back to you after I have had a chance to play

My set-up is a Tevo Little monster completely overhauled electronically...So I am interested in a Bowden set-up.

Best,

Andy

@mrehorstdmd It’s the filament being ground, which then does not move

Hi,

So I have the Tevo Little Monster with about 600mm of tube, would the BMG be ok?

Best,

Andy

Thanks for the swift response- which Bondtech should I go for as there is QR and BMG, I am using the Bowden setup.

Best,

Andy

Hi there,

In the process of configuration I have noticed that there is a serious amount of clicking comming from the E3D official Titan extruder. I have dismantled and resented this extruder numerous times...more than 25 ... at least. My wife is fed up of hearing about the failure of the extruder and even offered the money for a replacement:)

Is Bondtech any better? Will it work with the Duet3D Ethernet? Can I fix the Titan? Should I try?

Any help will be appreciated ... more by my wife perhaps

Best,

Andy

Thank you

Opps, did not know that, thought it "just did it" when retracting.
So now things are looking better

Edit, does the firmware limit the retraction? If you have firmware set to 4mm is that the most you can retract?

Best,

Andy

I'm still stumped and get lines across the part...does the firmware retraction not work?

Best,

Andy

This is mine:

M665 R170 L397.19 B155 H525 ; Set delta radius, diagonal rod length, printable radius and homed height

I changed the R value it was 155.

Hope this helps

Andy

Hi,

I am using Slic3r, I did have retraction set there but it seemed to make more mischief than expected. Should it be set in both firmware and slicer? I can up the firmware setting and try that.

Best,

Andy

Hello,

Thank you for all the replys - so far I have :

1. Updated the values for acceleration etc..

2. Tuned the H1 heater and added the M307 to the config.g

3. Worked out the steps per and changed it as required in the config.g

By printing the same part there is a greater density, also the filament is not...shiny when printed? The print on the right is the new print, the print on the left is the same as yesterday.

Could this be temperature or retraction?

Hi there,

See below for config.g details:

I'm using the new nozel X which is supposed to be polyphobic...it seems as clean as a whistle when I extrude, its a 0.6mm nozel.

I am using an e3d set-up: Volcano with Bowden titan extruder.

Hi,

I did not think of that, any suggestions how best to test?

Best,

Andy

Hi All,

Sad to be writing this as I thought I had found all the issues, sadly not the case, no matter what i do...I get massive stringing and artefacts in my test parts (see photos).

Its a lot better than it was, but I now don't know where the problem can be. I'm guessing its a sli3r con fig issue, unless my retraction and pressure advance are way off.

Sometimes it all looks perfect then something goes wrong. Not sure what.

Either way...I'm stumped any ideas?

Best,

Andy

Solved it

Pressure advance was set in slicer as well as in the firmware, removed the slic3er entry (it was set to 1) and all is well.

Fantastic, thanks for the reply's and suggestions.

Have a great evening.

Andy

Hi,

Good thinking, sadly nothing is shown.

Best,

Andy

Hi there,

I managed to upgrade my volcano to use the Nozel X. While doing this I found a lot of issues with the hot end. Its taken time but I am back to printing. I have enabled retraction in the firmware not via sic3er. I had some problems with retraction which are now sorted, however I have an interesting issue and am stumped as to what it could be.

The printer is printing as normal, then without warning it stops and the extruder runs for about two second solidly. As a result I get puddle points as in the picture attached. Is this a retraction problem? I don't know where to look to resolve this problem.

As ever any advice would be well received.

Best,

Andy
