Hotend Slamming into front panel & getting stuck

Recommended Posts

Posted · Hotend Slamming into front panel & getting stuck

I just received my 2nd UM2. After fixing all of the shipping loose ends, I found a minor problem that i was hoping to find an answer to.

When I change material, the hot-end slams into the front of the case and when this happens, it gets stuck there until it is done changing material.

Is this part of the g-code, a problem with Cura, or do I need to try a factory reset?

The printer came with Cura 14.03 already installed.

Any help would be much appreciated!

No, it does that. I think it's a firmware bug - but in all the cases I've seen it happen, it only does it during the initial set up wizard. When you do regular filament changes it stays clear of the front edge. Is that not the case with yours?

Illuminarti,

Thanks for the reply. I haven't performed the second filament change yet. I shut the printer off when it happened the first time. Then I powered it up again and the same thing happened. I let the filament finish loading on the second try and figured I would ask around on the forums.

It's good to hear that it is a firmware bug on setup.

I'll change the filament tonight and make sure this only happens during the initial setup.

After waiting for almost 2 months, I can finally start printing again!

I'm a little confused - when you change filament it likes to go to the front so that the bowden isn't bent so tight. This is fine and no one else complained about this. Where did you *want* the head to go during filament change?

When you run the first run wizard on the UM2 with recent firmwares, after the bed leveling completes, the head goes so far forward that it physically crashes into the front of the opening in the top panel.

gr5,

I sense a bit of sarcasm! The hot-end travels to far as to physically make contact with the front of the case, which is not a good thing. Do you really think i would be complaining about the hot-end moving to the front? that's just as ridiculous as your comment.

Illuminarti,

I confirmed tonight, that this only happens during the initial setup.

Mmm, it indeed moves all the way to the front, I'll make a minor tweak to it so it does not hit the casing. (Not that it will harm anything, it's locked in place due to the motors locking it)

None intended! Sorry! After I wrote my post I re-read it and I also sensed sarcasm and thought maybe I should rewrite the post. Then I thought that editing my (already posted) post might not help as you might have already gotten it as an email (I follow all posts that I post in). So I left it as is.

This is a new problem for me. I didn't know the head was capable of touching the front panel - I thought it would hit the block first like it does on the sides and rear.

No worries gr5.

As I said in the first post, it's a minor issue. In any case, I always respect and learn from the wise advice that you and more experienced assets of these forums bring to the table.
