HELP with ender 3 duet2 wifi

[bob0191]

Hi i am having a real issue with my printer at the minute! I must say im no where near an expert with any of this
I bought the ender 3 pro v1 roughly 3 years back which lasted 3 days before the main board melted so i went straight for the duet2 wifi which took me 3 days to setup
along with that i purchased linear rail for the gantry and duel z kit
Once i had this working the printer was working great now here comes the saying dont fix what wasnt broken !

The other month i see there was a firmware update for duet2 wifi and web control which i followed the guides and went on perfect i also see there was an update for cura which i also done cura from v4.6 upgrade to v5.1
it wasn't until after i found that the gcode had updated and i couldn't use my original coding no longer on the duet2 files which was fine i persisted for another 3 days to try and convert everything over which i did and got everything working again to my knowledge

Now i tried to print a new project which totally failed the material was being printed onto the bed all lumpy and sounded like bacon in the frying pan
first thought was that the filament has had it and needs to be replaced (filament was approx 3 years old) i of course kept this in a dry box and use to dry it in the oven prior to print for around 5 hours

So i ordered a roll of new filament PLA 1.75 loaded it in and proceeded to try and print which the exact same results happened spitting and not a smooth extrusion onto the bed

I then went on to calibrate the extruder which made no difference i thought i might of made an error with the printer settings which if im honest im not that experienced enough to see if there was an error i think my thermistors are slightly out but by a couple degrees but other than that it seems to all work

I then tried to reslice the STL file on the older cura software which didnt make any difference

now the interesting part is if i print an old file that was uploaded to the web control prior to update of firmware it would print it fine but anything i try and do now will not work

im now at the end and cannot work out what is going on if anyone could help that would be great but as i said im no expert! and cant keep playing the guessing game ive put hours into trying to get this working again but cannot work out what the issue is ive pasted in the below any help would be appreciated.

now the interesting part is if i print an old file that was uploaded to the web control prior to update of firmware it would print it fine but anything i try and do now will not work

I assume those old files were also sliced with your previous version of cura? You should go through your printer and slicing setup between the two versions and see what is different.

What kind of a hotend thermistor do you have? Is it the original Creality thermistor, or have you changed it? These thermistor settings in your config appear to be for an E3D thermistor.

Are you using mesh compensation? I see a G29 in your new sliced file after the homing, but I don't see that in your old file.

[bob0191]

@Phaedrux

hi thanks for the reply

at the minute i have tried slicing through the old version of cura and the new
Either make no difference they both print exactly the same
The old file sample i have put on this thread is a file that was uploaded to the duet prior to the firmware update and this one prints perfect no ringing or spitting at all i transferred all the printer settings and profiles over to the new version of cura and checked the machine settings match up

I mean the printer seems to move as it should but as the filament is extruding its spitting and bumpy which is why it confuses me that the old file prints fine and only seems to be the new stuff i try on whether its sliced on the v4 or v5 which is why i cant determine if its something to do with my coding on the duet or the cura Hindsight i should of updated one at a time instead of both together but mistakes were made

yes i have been using the mesh compensation i will try removing the code and see if this would make a difference

the thermistor im using for the hotend is the one that came with the e3d v6 along with the heater cartridge but i have noticed that this seems to not be as consistent temps as prior to firmware update seems to over heat and stay a few degrees over the target temp but even with this old file still prints

[Phaedrux]

Can you make a video of what you mean about the extrusion spitting?

[bob0191]

@Phaedrux

hi so i did record the video of the printer but i have now removed the g29 code and all seems to be working again ! i think the spitting must of been where is was trying to adjust the height on the z and missing the bed

i appreciate your help amazing what very little could cause the printer to be unusable!

thanks again !

@bob0191

hi sorry another quick question if you wouldn't mind ive attcahed a picture of my heater graph im currently mid way through a print but should the values be this far out ?

[Phaedrux]

What firmware version are you running/

What PID tuning command did you use?
