Re: Persistent Pause Print Failure/Belt Grinding + Layer Shi

Not sure on the pause question - I have never had any luck 'pausing' a print - I always end up with problems, so just avoid it these days. When it comes to layer shifting, I found all my layer shift issues came back to simply printing too fast. What do you have your travel speed set to? What about o...

Re: Rostock Max V2 Streaming via Octoprint

I tried printing that clip a few times but each time it would snap as I tried to fit it.

So zip tie to the rescue!

Re: Supports get knocked over

Thanks, I'm pretty gutted. Mainly because it's not obvious why this would happen, and secondly because it was going so well until the failure!

I havent had much luck with pausing prints. Every time I have done it in the past, I end up with a nasty 'ridge' line visible in the print at the pause layer.

Re: Supports get knocked over

Well damn ... my print failed at 93% :(

The extruder couldn't push the filament down the bowden, ended up burring a divet into the filament and that was that. I'm guessing the additional friction from the bowden tube being coiled up was the cause?

Anyone else have any thoughts?

Re: Supports get knocked over

OK, so it seems like I'm just going too fast. I'll change my settings and see if that improves things.

Re: Supports get knocked over

250 might be enough to start missing steps, especially around the edge of the print bed. After steps are missed the head could go anywhere. Aside from that, setting up a z hop is a popular solution for nozzle drag during travel moves. Thanks, I had considered z-hop as well. What's a reasonable amou...

Supports get knocked over

Hi folks I've been avoiding supports for ages because I always seem to have problems with them. Now I'm doing some prints that require them! I've tried supports generated by slic3r and also making them in Meshmixer. I've tried making them super thick (8mm diam) with really wide bases for better adhe...

Re: Just can't get these prints to stick...

I think the problem isn't bed adhesion, but print shrinkage. It doesn't matter how good your adhesion is, if the rest of the abs is shrinking, it's going to curl and pull it off the build plate. I would try enclosing the printer bed. You can even use something as simple as some a3 sheets of paper st...

Nice save!

Are you printing with PLA or ABS?

What's the material over your print bed? Almost looks like tinfoil ?

Re: Cannot Home towers

Check the cheapskate bearings and see if they aren't gripping the pylons too firmly.
Check your belt tension and inspect the belt for indications of wear.
Check in the base near the steppers to see if there's a pile of black dust that could indicate the belt is being chewed up.

How fast do you print?

I'm sure this is a loaded question, as it depends on the result you want, but I'm interested to get a sense of how fast everyone is printing. I just had a print fail and I suspect it may have been because I was pushing my hot end too hard. I was printing from 40-80mm/s when it's only rated for 20-50...

Re: Extruder motor overheat

Steppers do run very hot - however over 90 degrees is probably too hot. Check your extruder assembly. Make sure that the filament path is straight and it's not rubbing against something. Check that the cog is lined up with the filament path. A useful test would be to remove the bowden tube and just ...

Re: Extruder motor overheat

I found that my stepper runs hot regardless of the firmware change.

As such I printed this little fan shroud for the extruder. My stepper runs nice and cool now.

Re: Removing print from plate!

Strongly suggest against using force to remove the print from the plate. Eventually you will pull chunks of glass out of the plate and then you'll need a new one. What always works for me is putting the plate in the freezer for 10 mins. It should pop off with almost no force. Sometimes I open the fr...

Re: Printing small objects - Marvin

Well it seems better overall, I printed 3 marvin's at once, and of the 3, this one came out the best. The other two had a lot of roughness on the front and I would say were worse than my original attempts. https://dl.dropboxusercontent.com/u/908196/Marvin/Photo%2015-01-2016%2C%208%2021%2031%20PM.jpg...
