Re: Printing small objects - Marvin

No supports here - as part of the instructions they say that the file 'doesn't need supports'.

I'll purchase a smaller nozzle and see if that helps.

Hi folks I normally print fairly large, functional parts, but as part of signing up to 3dhubs you have to print a tiny 'marvin' figurine. I've been having some problems getting him to turn out properly, here's how it looks: Print 1: done at my normal settings, 0.1mm layer height https://dl.dropboxus...

Re: Printing in a drafty room

Strongly suggest using some adhesive, I use UHU glue stick. People also recommend Elmer's Disappearing Purple. Cover the bed in horizontal and vertical 'stripes' - I find one application is good for a few prints, depending on how difficult a print it is. Surprised you've made it this far without any...

Re: "Saving" a print

Thank you for the advice. I have read Mhackney's post and I feel like I'm just starting to understand some of the details of the printer. I think I need to print a new fan shroud or tweak the old one. It kept bumping into the print and either jarring the print loose or the fan would swing out of th...

Re: Incorrect dimensions on printed objects

Does it also mean that if very popular designs on thingiverse have no tolerances built in, then other printers are capable of producing accurate dimensions? Surely if this is a common slicer / printer issue, all popular designs would have a tolerance built in to be successful.

Re: Incorrect dimensions on printed objects

Ok so this comes back to my earlier question - should I expect accurate dimensions from my printer?

If not, I can deal with that, but so far no-one has told me that I shouldn't expect +/-0.05mm accuracy from my printer.

Re: MC auto bed leveling problems

I haven't tried MC's bed levelling but it seems odd that you'd run out of turns on the cheapskate endstop screws. They're for making very fine adjustments. If you screw them all in to around half-depth and then re-calibrate your Z, do you still have one axis that is way out? If so I suspect there is...
