Hi guys. Thanks for the help. Together with your help and a bit of investigating I tracked the problem down. It looks like the wire form the Y limit switch was pinched between the wall and the extruder stepper-motors during assembly, and over time I think the vibrations managed to break the wire, shorting it out it obviously fooled the controller in thinking the the print head is at home whenever the controller checks. I repaired the wire and the problem is now fixed. https://drive.google.com/file/d/12590mUfi3Wl5eNwwnUAsJ05yxbsvBdQv/view?usp=drivesdk

@gr5 https://drive.google.com/drive/folders/1zkrZQTsJQ6RhzGGn8YvCx8hAAi69s5zp This is the link to the Google folder. The thing is, the printer prints 100% no issues, so I would think all your ubove mentioned issues will also affect printing not just the homing of the head after the print.

Hi Mari. I'm sorry if I'm not clear. I'll try to give a little more more details. After a print job finish I ecspect the print bed to drop to the home, (bottom.) It does that. Then I expect the print head to move all the way to the left and all the way back, default start position. (power on position) It does not do this. What it does is it only moves all the way left but not all the way backwards. Have a look at the 2 videos named print finishing. And you will see. What happens when the print finish. I have to manually move the head all the way back to the start position by hand before I start a new print. If I don't move head by hand and I start a new print, the print head moves forward (from the position the last print stopped) and when it reaches the end of travel the steeper motor tries to keep moving further and then the steeper skips on the belt because the head can't physically move any further. There are no limit switch the determine the front left stop. This is done by stepper-motors steps. In the firmware... I think. Also if I go into the menu "home head" it does not home the head. Watch the video "home head" and you will see what it does. I actually press the home head button repeatedly so you can see what it does. It move the head slightly forward everytime. And not to the back. So for now I have temporary work around. Move the head by hand. Before every print but this is not the way it is supposed to work. Please let me know if I can explain anything more.

Hi Ultimaker Team/Community I'm looking for some advice. I have an Ultimaker 2 extended. As I'm sure you are well aware, the normal operation after a print; is for the print head to return home. Then when a new print starts the bed lifts to about 2cm below the print head, and the head will move to the front left and extrude(Purge the hot end) then move to the start of the print, and then start to print the first layer. My printer prints 100% - No problem with printing! My issue is... it does not send the head back home, Not after bed levering Not after a print. Or on startup When I start a print, what happens is this; the printer moves the head forward as if the "IT believes the head was at the "Home" position Top Left! But it moves forward then the stepper motor slips the belt "Until IT believes the head is now at the ready point to start the print/extrude/Purge" The Left to right axis works 100% Then the normal print sequence starts and it prints 100% After the print, it moves all the way to the left but not backwards, it stops at the same level the the print ended at and it does not return home on that axis.... What can I check? As mentioned it prints 100% I can post a video if it will help. https://drive.google.com/file/d/1-6VnxWRQ-lBh14UoNG9h2X5oEjvgG2wA/view?usp=sharing Thanks, Schalk
