All prints are raising up on one edge

[TedMilker]

The aluminum disk was purchased and a machine shop cut it to size here is the link: http://www.sandsmachine.com/alumweb.htm

Did you have S&S machine it for you? If so, care to share the drawing? I may get one of these in the future for a print surface. Thanks for the link!

No, S&S does not do the machining, I took it to a local shop where they cut it into the smaller round shape the same size as the Onyx for a $30 charge. I drilled
the holes using the Onyx as a guide then used my drill press to countersink for the #4 screws. The rounds I bought from S&S are 5/16" and perfectly flat. Mine
had 4 holes in them already but they were outside the cut line so it didn't matter but they may have changed the sizes so be careful what you buy.
Edit: I just looked at the link and the bottom listed plate that is 5/16" is the one I bought. I do not recommend that you try to cut them to size yourself unless you
have the proper saw and blade. That thick aluminum chatters like a squirrel in heat if you don't have the proper tools. The $30 I paid to my local machine shop to do
it was money well spent. If you took the Onyx with you the local shop would drill and countersink the holes, take a #4 screw with you so they know how deep to countersink
if you go that route. If the heating Onyx can bow that plate then my name is Silver and I have a rider named the Lone Ranger. I also run my Onyx on 24V, I don't know the
results of heating that big plate with 12V but I can imagine it would take a long time to heat.

A piece of aluminum 1/8" between the Onyx and the glass can help to distribute the temperature. A wall you mentioned is also a good idea to minimize drafts. Some use a section
of Sonotube (not sure of the spelling) but it is for concrete, can work also. Heating the Onyx with a 24v supply can get you to temperature faster and you could try a hotter bed
temperature but I recommend a DC-DC SSR feeding the 24V into the Onyx although I have received arguments on that. (Some would rather run the 24V through the Rambo).
Just throwing out some ideas.

I have installed an alumninum sheet. It's about .69mm thick.

My prints are still raising up on all edges from the bed and splitting on the corners throughout the prints.

Bed temperature is 90C on first layer and 93C after that. Extruder temp is 228C. I have perimeters set at 2. Infill is at .20. I'm using a brand new .50 nozzle. Layer thickness for the first layer is .20 and all other layer thickness is .20. Printing with skirt and brim. I'll try again today with a wall around the printer.

Anybody know what could be causing this?

Thanks.

Your last picture shows delaminating during the print... I t could be from your filament.
Have you tried different filaments ?
What brand is it ?

A layer fan could do that too. Do you run a layer fan ? You should not use layer fan with ABS.
If you don't have layer fan, is your printer near a door, or a window ? Is it in a garage with bad isolation ?
ABS really does not like wind or temperature changes. Some even build an enclosure for their printer, that helps with ABS.

I did have a fan on. I am printing the same thing today with no fan and with an enclosure. The filament I believe is from Octave off Amazon:

http://www.amazon.com/Octave-1-75mm-Fil ... ctave+blue

The printer is in the basement and in the winter the temp is around 63 down there. My dehumidifier regulates humidity at 35%. I forgot to mention that I am using cheap hairspray as well and have never really gotten any of the corners to stay down.

When you say layer fan, do you mean a fan that's on for a certain layer only?

[Eaglezsoar]

A layer fan is normally turned on after the first layer and is on throughout the print. It is used mostly for PLA and not for ABS.
Are you using the recommended hair spray? It has to be an extra super hold like these:

[enggmaug]

As far as I know you can mount fans on the platform for 2 different uses.

The peek Fan will blow on the peek section of your hotend to cool it down, and prevent the filament to be melt before reaching the nozzle.

The Layer fan wil blow directly on the plastic being printed. It allows PLA to cool down and reach the solid state faster. It is almost necessary for PLA, but not recommended for ABS, as ABS will warp and delaminate.

[JAY]

Printing with the fan off and an enclosure didn't help. This is how the print turned out. I'm printing ABS here btw.

This is the hair spray I'm using. Should I try something else?

The ABS is from SeeMeCNC.com

What else can I try? I have other rolls of ABS from Octave off Amazon.

[Eaglezsoar]

Try this one: http://www.amazon.com/Garnier-Fructis-A ... +hairspray

It's not only warping away from the plate, but also delaminating... I guess I would try playing with temps.

Did you check your thermistor accuracy with a thermocouple ?

[JAY]

I'll borrow a meter with a temp thermistor from work. Thanks.

Is there a proper way to store ABS rolls? I think I've had this roll most of the winter. The basement is cold and dry. I have a new ABS roll still in a sealed bag. The fact that it's shipped in a thick sealed bag..should I seal unused ABS if it sitting for months?

[enggmaug]

I believe ABS is not too sensitive to humidity or temperature.

Other filaments can be, but not ABS, as far as I know.

They should be kept in a low humidity area, if possible. If not possible they should be sealed in an airtight bag with desiccant packets.

I'd bump your hot end temp up a bit. Let's say 235. I don't like the delamination...usually ends up being a hot end temp thing in my experience. I'd also recommend making sure the temp you're re reading is the actual temp.

[McSlappy]

Is this layer delamination only occurring on one corner?

[JAY]

No. Delamination and edges raising on all corners.

I would go back and make sure your Z-height is calibrated correctly at the center, all 3 towers, and between all 3 towers. My printer was working just fine for a long time, then randomly I started having problems with lifted prints (no delaminating though). Ends up my z-height was all off for some reason (probably something I did on accident while upgrading firmware) and my nozzle just wasn't close enough to the bed to get the first layer to stick. Recallibrated z-heights and I was good to go.

My extruder temp is 2C below what it is reporting in Repetier Host. I think this is ok.

I raised my hotend temp for ABS from 230 to 237. Given that Repetier Host reports 2 degrees lower it should be at 235 now. Will update changes in prints soon.

As far as bed temperatures, I found that with Repetier Host reporting the the bed is at 91C, most of my bed temps actually range from 79 on some edges to 86 in the middle.

And I just cracked the glass trying to do this so there goes my leveling. I had a small plastic piece under an aluminum weight with the thermistor between the bed and the plastic piece.

Just a thought, but even though the ABS you're using is from SeeMe and should be good quality, maybe you got unlucky and have a bad roll of plastic. Do you have any other ABS on hand to try?

[Eaglezsoar]

That had to be a sickening feeling in your stomach when that glass cracked.
Stuff happens but it always seem to happen to us no matter who we are.

Trying a new roll from Octave now.

Yes thanks Eagle.

[JAY]

I got the new glass and leveled the bed. Still no luck. I tried a new roll of abs and pretty much the same thing. Beginning to think it might be the cold temperatures in the basement. It got down to 63 on real cold days. I live in Indianapolis.

[JAY]

Increasing the bed temp helped with the print raising off the bed. I had it pegged at 105! It was only able to reach 103. But the raising stopped. Can't imaging printing like that in the long run.

Still have the splitting throughout the verticals though.
