RepRapDiscount "Bulldog XL" Geared Metal Extruder on a Solidoodle 3! (Page 9 of 13)

I'll take a pic tonight of the earlier failed reprint tonight, thanks!

EDIT:  I also didn't mean for that post to sound negative, was more a comment for me as I'm learning.  Slic3r settings sometimes lead to interesting results.

Here's my failed print where the axis shifted by accident (so ignore the top bit)...  I unfortunately realized I snapped the support off by accident getting it out, but you can see on the right side (and left) of the nut holder that they weren't connected at all where the thin sections started above where the intentional gap is. From that point up the end was an independent piece from the main piece, so approx from the middle of the nut out was not connected.

It's the reason I had to reprint the carriage   The original one I printed I didn't realize it wasn't supported properly from the small gap, broke, and i noticed the belt screw was being pulled out slowly as the now unsupported plastic began to warp.  I also don't have the E3D head properly shimmed (I've tried to fudge it, but obviously not working.)  Hoping this weekend to get the old mount out, belts properly re-tensioned and the E3D properly shimmed.   If that doesn't work out, I'd definitely take you up on your kind offer to help me out     I printed out this adapter, http://www.thingiverse.com/thing:276280 , hoping it will work better than the couple washers I have jammed in that sometimes pop up.

Also any of you have a problem with your extruder stepper getting really hot? I think its melting my filament slightly by the drive wheel and causing my extruder to slip.... Then my print fails!

My fan is working fine... Maybe I have my driver to high? Its hard to tune with the bulldog since you can really hear it skip when tuning.

I better turn it back down then..... : )

My gearbox becomes almost unbearable to touch if I need to change filament after a print or make a repair.. Ill grab a thermometer off  the a zon.

So I printed it out, but can't for the life of me figure out where it's intended to go   Doesn't quite fit where I had expected it to.  Since i had it all apart, I ended up using a couple of washers, and seems much more solid.  I may print at some point a spacer at .1mm that I can insert into the gap instead with some tab so it can be removed easily.   Printer had been squeaking all of a sudden, and finally found one of the y belt mounts was a bit too tight and bolt was low on grease.  Sounds much better now.  Ugh, now the fun of recalibration begins.

Very nice!!! be careful drilling in that area it splits easily.  That's the voice of experience so I would suggest simply melting the holes or run your bit backwards.

If I had time I'd just implement your whole assembly into the design.  Any reasons that you can think of that would prevent it from being on the left side?
Oh, what kind of spacing would you like for those holes?

Well if I get some design time I'll add a couple of holes for you and just post it here.  Should only take a few minutes.

Go this working literally just before going to bed, getting closer!  Probably going to need to change the switch out after reading last night a bit, but good enough for testing:

Looks perfect, thank you!!!!
