Print quality issue
-
Looks like you might be printing to hot or to fast. You sure about your temperatures are correct?
-
What is the current extruder?
Do you know what thermistor it is?How did you calibrate the esteps? It definitely looks over extruded or printed way way too hot.
When printing those temp towers did you actually edit the gcode to alter the temp at each step? They all look the same.
Can you set the temp to 180c and then try to extrude as you decrease the temp. We'd expect that at 160c or so you wouldn't be able to extrude anymore. (note you may need to allow cold extrudes with M302 P1 before testing)

Also a temp probe could be used to confirm your hot end is in the same ball park something similar to this might help you. (or cheaper or even one on a multimeter might do)
a bit of kapton tape to attach the probe to the heater block

I printed two temperature towers and they are both awful
did you script it so that it changes temperature at the layer?

I'll try that. I'm pretty sure I have the correct thermistor values since they were specified for me (from the kit I got) but the thermistor model numbers were not listed.
The temperature towers did change temperature and I was able to see it correctly set in the duet web control.

I plan to buy an E3D Hemera but I have no idea when it will be in stock. What should I do?
same situation here.
i ordered this

I just did this test and it stops extruding at around 160 C. I'm at a loss right now and it is difficult to troubleshoot since I don't have another hot extruder to test with.

Is the nozzle size different than you expect it to be?
Is the Z axis moving the commanded amount?
The flow adjustment in Cura set to more than 100%?
Post a sample gcode?
Try a different slicer.
Are you editing the right config.g? Sometimes people will have the folder structure messed up a bit and will be editing files in a different place than the firmware is actually looking at. It happens.
Process of elimination.

@Phaedrux I replaced the nozzle with a genuine E3D V6 0.4 mm nozzle, I measured a print 20 mm in Z was exactly 20 mm, CURA is set to 100% flow, I edit the config.g in the duet web control system editor tab.
What slicer would you recommend? I just reinstalled CURA for this new printer and my profiles are as stock as they get. I am most used to CURA but also used ideamaker in the past.
Here is benchy which printed just as badly as those temp towers.

CFFFP_3DBenchy.gcodeIdeamaker has some very good "out of the box" profiles and their slicer is much better than cura or S3D

I can't see anything obvious in your gcode file.
Ideamaker is fine to try. There's also PrusaSlicer that's pretty easy to get up and going.
I'd also try taking another pass at the calibration. Comment out the M307 commands in your config and start fresh with a PID tuning and then extruder.
