Is that glass filled? Does it look the same with normal filament? Glass filled or carbon filled always look good.

I think I can confirm that too. Last night I printed something for my son and it came out perfect. It’s not big, of course, but it came out really well. Tonight if I can I’ll try to print something less ā€œcurvedā€.

I only had one problem at the beginning of the print, it seems that the nozzle had not been cleaned well and it brought with it a small blob of filament that I promptly removed from the first layer! Latest beta firmware installed

Yes, it was, but I also have other parts printed clean

Objects like this i have no problems printing. Its objects with long straight walls with geometry changes.

Guess ill throw in some tpu layer lines. Dont want to be left out lol.

At this point I am very frustrated. My machine started having issues to the point where I can’t print with my Left nozzle at all now. It shows extruder overload on the left Nozzle ONLY. After messing with it for a day and half I’ve concluded the temperature reading on the left nozzle is no longer accurate. If I do a flow dynamics test everything is fine. I found out the flow dynamics test is done at higher temperatures. I tried changing the nozzle 3 different times and used multiple filaments and get the same issue with the LEFT nozzle only now. If I put those same filaments or nozzle in the right slot it works. At first I thought the z-height changed and was causing too much pressure. But I figured out if I change the temperature on that Nozzle only +10*C it will start to print. I can print fine on the right nozzle at regular temps. Even doing the high precision nozzle offset the printer will print the filament like chalk(with PLA) due to the colder temperature in the left nozzle… If I try to print PETG it will cause the overload and almost nothing is extruded.




Sorry for the blurry picture for the error message, it was late at night, I was frustrated, and I didn’t check the picture at the time I took it.

Do you happen to have a multimeter with a thermistor attachment? That would be able to confirm if your hot end heater isn’t heating properly.

Great idea. Just checked with a fluke 1587. Definitely off on the left nozzle.

That’s a huge problem! 15° off is crazy. Definitely support ticket worthy. I wonder if it’s just a bad heating unit/thermistor or if some of the boards are involved.

would you try a factory reset again? you know, nothing much else can do at this stage while you’re waiting for support ticket reply

I’ve done it 3 times. I even down graded to the official release, and then updated to current beta. Same issue. It actually worked for a few prints and then the problem came back

EDIT: They were sending me a new x-axis with tool head. But after looking online the x-axis with tool head that I can find is only the back carriage part and not a full tool head. This was before the current temp issue was found. I’m still not entirely sure what they are sending. They asked for my shipping address and I replied right away and didn’t get a response. I would assume they would send it to the same address as the machine or at least respond that it was shipped out after I replied confirming the address. I’m still waiting on another reply. I ordered some extra filament at the same time they were sending the parts. Filament came in in 2 days. The replacement parts I can’t get a tracking number or confirmation if it was shipped.

What a beautiful multimeter :heart::heart::heart:

Thanks, I’m an electrician and UL508 panel shop. It gets lots of use. I’ve had this particular meter for about 5 years and it has worked great. Probably tested 500+ motors with it. Very reliable and repeatable results.

Having such a rough time with this problem. Support hasn’t gotten back to me in a few days. I’ve spent a ridiculous amount of time on troueshooting this just to get the exact same results on every print no matter the model that I’m thinking I might have gotten a lemon. :expressionless:

Looks like z wobble. Try print a zwobble tower

I ender up taking the entire tool head apart and putting it back together. My gear wasn’t pressed all the way in and several screws were loose. After I got it put back together I printed this:

Gonna try a bigger print again and :crossed_fingers:t3::crossed_fingers:t3:

I would try printing something else. My printer prints those same files absolutely perfect. Because they are going slow due to single wall. Try printing something large and square that’s printing fast

Where can i find a standard stl / Modell to check, if i have the same issure.
What are the parameter to check ?
Vase Mode or min perimeter ?
Min dimension ?
Can anyone link a modell ?
THX

WHY WOULD YOU NEED TO CHECK THAT? Why would a new printer have that defect
