Banging head against a brick wall Request Help!



  • Hello All,

    I'm new to the forum and Duet 3d.

    I recently purchased a duet wifi board for my Ender 5, and for the last 3 days I've been trying to get it working. It took me two days to get it to home correctly and now the current situation is that it homes, but when I start a print (using Cura 4.1) it heats up correctly it then lifts then lowers the bed slightly to purge head, it then starts to draw a line BUT it doesn't stop the X keeps going to the end of the frame and i have to hit the emergency stop!

    I have been searching but can find very little on the Ender 5 with a Duet board. I have tried changing my start code in Cura and I have used a Ender 3 profile in case it was the Creawesome Ender 5 profile causing the issue, all do the same.

    Here is my config:

    Please help

    Your X and Y steps/mm are both 160 which implies that you are using 0.9deg motors. Is that correct? Do the axes move by the correct amounts?



  • Thanks for the reply.

    My motors are standard which I presume are 1.8. This is my first time getting in depth with G code. I should also note that the head is moving a lot slower than when it was running Marlin.

    these are incorrect for the ender 3 and 5.

    see the ender 3 guide. (ender 5 is basically a more stable ender 3)

  • Thanks, I'll take a look



  • I followed the guide, thanks. However when I tried a test print, small overhang scale, it immediately started to print in the homing corner and didn't extrude anything. Am I right in thinking that this is possibly to do with the cura settings? As the machine now homes perfectly.


  • administrators

    It's up to you whether to make X0 Y0 the centre of the bed (which is what I do) or to make it one corner of the bed. See https://duet3d.dozuki.com/Wiki/Centering_the_bed_or_setting_the_bed_origin. You need to configure your slicer (Cura) accordingly. It sounds to me that you have configured X0 Y0 to be one corner of the bed but configured Cura to centre the print on X0 Y0.



  • You may want to go through the rest of that configuration and commissioning guide for the Ender 3. It also includes a profile for Cura for the Ender 3 which should have everything setup correctly for orientation. I think you might also have a motor direction or homing direction flipped. The guide would help you identify it.



  • @phaedrux thanks will do



  • This post is deleted!


  • Can you post your full config?



  • @phaedrux Thanks for the swift reply phaedrux. I'm glad to say that the action of copying my heater config into chat made me realise the figures were wrong, so I popped into config and changed them. It appears to be working fine now, I'm just running a M307.

    I am grateful for the help. It's good to know that there is a place for advice, I'm currently suffering from a psychological disorder that makes it hard for me to concentrate for large periods of time and also makes it difficult to problem solve.

    So your help is appreciated.



  • Glad you got it figured out. There's always great support from many people here, so come on back whenever you get stuck.
