  1. Thank you all. I move it around and couldn't get any readings - it was stuck at 8 degrees.

    Fiddled with the connector since it seems quite flimsy, but no joy. In the end, switching the the alternate cable solved it, so there must be a weakness somewhere else along the cable. I pushed the heat-shrinked black tube through a bit more to ease stress and for now I've got it working, so I'm happy.

    Thanks again

  2. Hello I've got a UM1 that I use to print PLA at 220 degrees with Cura as my slicer.

    Sometimes, for no apparent reason the temperature gets hotter than 220 and heats all the way up until the Ultimaker shuts down with a MAXTEMP error.

    It causes the PLA to burn and release smoke, which is worrying because I am in a building with over 500 people in; we have a shared fire alarm system. I don't want to be responsible for causing the evacuation of 500 people!

    Any ideas, or need anymore details? I hope someone can shed some light on this.

    Best

  3. So here's the same piece after adjusting the pulleys and although it is definitely better it's still skewed.

    This is a shot of the belt post-adjustment. It's still close, but definitely not touching as far as I can see now.

    There is one thing of note that happens to the belt during printing and I have recorded a video of it here:

     

    As the motor's direction changes the belt twists, is it possible that this could be causing excess friction?

    Any other suggestions?

    Cheers

  4. Thanks a lot both I've tried some silicone spray on the rods (this OK since there is apparently a self-lubricating bearing?) and I've moved both stepper pulleys away from the frame. There was definite rubbing since there were marks where the bands had rubbed on the wooden frame. I'm just reprinting the piece posted above so I'll let you know how I get on.

    Thanks again

  5. Hello,

     

    I have an Ultimaker 1 that has been relatively trouble free until suddenly I'm getting skewed/leaning prints.

    I spotted a loose pulley and tightened that up (but I think it was on an axis not relevant to this problem)... I can't see any other loose pulleys.

     

    Any ideas what might be causing it?

    This image shows the orientation of the lean on the Ultimaker.. X Axis?
