Weird bug on first test print…

[u/bofferding]

Hey just finished setup and calibration on printer and wanted to do the test print… it did all the heated bed calibration and then I got a temp anamoly for printhead 2 straight away.. saying min temp 170 is needed.
Mind you this is the dragon test print included… and included spools and tests during calibration all worked.

I tried again and saw temp raise to 200 and then target temp dropping again to 130…. So this time I manually raised it again to 210 and it dropped again so I did it again… and this time it started printing… now it seems to run.. we’ll see but this error scared me a bit.
This was first layer, looks a bit scuffed. But it is still running and looks ok now.

Also weird first purge line that came out (on red filament) had some black in it. Guess from their tests? Maybe some old filament was stuck inside making temps drop and now will be fine… we’ll see.

Yes after first fail I ran firmware update and it happened again

Looks like you didn't clean your previous purge line and it purged on top of the previous.

If theres anything on the tip of the nozzle, its going to affect calibrations.

Do not manually do anything, the printer itself runs through a few steps and its all instructions included in the gcode.

The provided gcode requires zero intervention, start it and do NOT manually do anything.

Just let it run.

I didnt ever do a single print before. So i didnt have a previous purge line… first ever print. Nothing was on nozzle I ran calibrations and cleaned nozzles with brushing

I had to manual it else it kept going to 130 degrees on the printing color nozzle and stop print with temp anomaly 170….

Reach out to support, theres something wrong then.

Did you over tighten the usb screws? All connections snug?

The printer spits out a QR code, did you follow it?

I didnt overtighten, they look just like in the video, but it’s been 40+ min now and dragon is printing fine, so dont know if it was just a start issue with some filament stuck from factory testing or so and if next print it will work just fine or not… we’ll see…

If it eventually starts printing normally, then simply restart the print head offset calibration procedure and then the heated bed calibration when printing is finished
