I got the heater tuned just fine...used the guide that I found on the duet site. Now I have a much worse problem - every time I start a print, the Titan Aero that I'm using clogs in the throat/pipe or it bunches up in the hobbed gear. I tried several different temps and they all do the same thing. I followed the setup instructions on E3D's wiki page and it seemed like it all fit into place correctly, set the steps/mm (837) and then attached it to the printer (that's when I started having issues with the heater cuz it was brand new I guess) I finally got the heater working correctly (I thought) and now I can't even get one minute into any print job without it clogging up completely to the point that I have to disassemble it ...WTF am I doing wrong?? I dumped the TronXY motherboard cuz it kept having one issue after another, now the Duet2 is doing the same thing!! I am really about to give up on 3D printing all together...thousands of dollars invested and not one printer works the way its supposed to...

Every time I try to run M303 and autotune the heater, I get the message "No heater has been tuned yet" And it won't let me do anyting. The reason I'm trying to tune the heater is because I keep getting "Heater Fault, heater heating to slowly 0.7C/sec" I can't run any prints, it just errors out. I can't test my new Titan Extruder because it won't get hot enough to extrude PLA...I'm running a 24V 500 watt 20 amp Meanwell PSU and it seems to be working fine...it just seems like the power to the heater unit is fluctuating. I've replaced the heater and thermistor twice (once with older working ones and then with brand new E3D ones) and they are the correct voltage and wattage because I tested them on my LulzBot and they both worked fine. I'm stuck...what can I do to fix this heater issue??

Also - I had one other question...where do you set up the nozzle size? Whether its 0.4mm or 1.0mm? I cannot find it in the Duet2 controls anywhere??

I had to reduce it from 4000.00 steps per mm to 450 steps per mm then the distance checked out with a caliper...5mm down=5mm Thanks for your help!

And thank you, that link did help in figuring out the direction of the axes and the correct movement...

Ok...I have them all homing correctly, now the Z axis is stepping way to much - when I tell it to go 25mm it goes more than halfway down and the Z_Max is 400mm not 50mm???

Whatever that "G1 Z5 F6000 S2 ; lift Z relative to current position" does, its what causes the up and down problem with my motors...I removed that line and they all home correctly now except Z which is just reversed...how do I reverse the z stepper in the config files?

Yes...X and Y both home correctly now, its just Z that still has an issue (its 2 Z motors in series, by the way) When I home Z it starts to go up, maybe 10 or 15 mm then it reverses and goes all the way down until it hits the top of the motors...And I tried substituting all the codes in the CoreXY setup guide and most of them made it worse...I removed all the references to Z in the two homex.g and homey.g files and that seemed to fix those axes...but Z is still a mess. I remember in marlin, for my CoreXY I had to reverse Z motor in the Config.h file even with the CoreXY mode turned on...

@dc42 It was 2.01, I realized I had to install 2.02 RC2 first...

So that's not what's causing the "homing" issue? The other endstops are all functioning correctly, but "E" shows "yes" like its triggered all the time...

Ok...X,Y and Z read correctly as "No" in "Machine Settings" and they show "Yes" when I trigger them, but it still shows an endstop for "E" which I don't have...how do I remove that? And now, when I home any axis Z goes straight up and doesn't stop even when the Z endstop is triggered...

All it says is X1 Y1 Z1...what should I change it to?

Yup...That's what it is...they all show "yes" when they are not triggered. I'll try adjusting M574 and see what happens-- Thanks!!

I read someone with an AM8 having this same issue...I can move in any direction if I use Pronterface or Simplify 3D, but when I tell it to HOME any axis then Z moves up and down and X or Y just moves a few millimeters...what can I do? I'm running a Duet2 Wifi on a CoreXY with 2.02 RC7 that I just uploaded to it...I recieved the board in the mail TODAY...It doesn't show any errors in the web interface, and from what I can see, everything is hooked up correctly. I do not have my Z-probe hooked up yet as I wanted to get all the axis moving correctly first. I'm running a 24v 500w 20 amp PSU with endstops on all axes

@spunone69 Nevermind...I figured it out...but it still won't home any axes!

It uploads fine until the very last file "dwc.js.gz" which errors out every time...

And if I try to home Z it just goes up and down once or twice...

I just got my Duet Wifi setup as a CoreXY and its doing the EXACT same thing! I can open Pronterface or Simplify 3D and move the axes in any direction, but when I home any of them it moves Z up and down and X or Y moves only a few millimeters...what is the issue?
