Hola - I'm trying to print a part that uses pretty much the entire buildplate on my M2, plus or minus a couple of mm. The M2's origin as the lower left of the buildplate and the work volume is 200 x 250 x 200. When it prints, it tries to print off the front of the buildplate and it stops at about 45mm from the back of the buildplate. I can manually move the nozzle over the entire build plate. ? TIA

I opened a previous version's Cura file and got the data from the settings

Thanks for the reply - I'm in CT. I found some 70D on Amazon, let's hope it's not a typo hahaha. Regards

Hi - Made some parts out of Hatchbox TPU, Shore 95A. They could be a little harder but I'm having trouble locating Shore 100 TPU - does anyone know a source? TIA Peter

Thanks for the replies - Regarding enclosing the printer, I've tried it on a Sindoh DP200 which is fully enclosed anyway...right now I'm running another one on an open Makerbot M2 but it has another 20 hours to go and it hasn't reached that area yet, so I don't know what the result will be. I made the first few prototypes with PLA but this is a functional prototype (it's a nail gun in most respects) and I need the strength of ABS to withstand test firing. What I'm trying now is a 12mm column that anchors the curling area to the platter and I will saw it off after it's finished - I just don't think the raft secures it enough. When it's done I'll post the result.

Hola - I've done (3) 20 hour prints of this part with no success. As you can see in the photo, it's a handgrip and it's bending at the end. It should be straight and flat and I have a raft support under the entire part. In the photo, you can see that I even tried adding a square column under the end of the part that stopped about 1mm away so that the raft would have something to anchor it better... It didn't help. It keeps turning up in a curl. The material is ABS, I'm running 250C on the hot end and 110C on the platter, printing at 60mm on a Sindoh DP200. Any ideas?

Yes, it does. I think it was a flow problem. I cranked the bed up to 95C from 60C and it helped.

My one at a time issue was due to the fact that my print head size was incorrect in the printer definition - it was 1.7 x 240 mm. Making it 1.7 x 1.7 allowed it to slice one at a time successfully. Thanks to the developers.

Hi Peggy - It's not specific to my printer, it's Cura. Set your layer height to 0.07mm with 100% infill and a distance equal to your orifice and you will see what I mean. I uploaded my project, you can try yourself. Those settings are not manufacturer-dependent.

Hi Peggy - Yes I did open the file you sent, but it was all-at-once and I need one at a time. I'm using a MakerBot M2, the latest version. I am not using any Support or Adhesion, so Brim is not an issue. I tested more and found that the problem is regarding One-At-A-Time vs All-At-Once. Cura can slice All-At-Once but not One-At-A-Time, depending upon the accuracy/resolution. I can slice 25 parts if all at once.... but why can't it do it one at a time? Seems to be a bug to me.

I find that if I have more than 3 parts, Cura 2.3/2.4/2.5 won't even slice them at "one at time". It says none of them are in the volume, which is untrue. It can do more than 3 if I increase the layer height (reduce the number of slices) and generally make the part lower quality but even then, there is an upper limit to how many Cura can slice. This should be pretty easy for the software to handle.

How do I share a project file? Google Drive? https://drive.google.com/open?id=0B5J2gg__lVTNcVhpV3JIaFA5dmc This project will not slice if set to "one at a time".... it should be a piece of cake. No version of Cura that I tried (15, 2.3, 2.4, 2.5) could successfully do it.

Sure - I've done some more testing and it is related mainly to "one at a time" vs "all at once"... it sure doesn't like "one at a time" with fine settings.

More info - I find if I set it from "one at a time" to "all at once" it will do a dozen but quality is definitely a factor in how it behaves. Make it too fine and it won't slice.

I am trying to make a batch of identical parts. They're very simple washers. Any more than 3 of them and it says "Unable to Slice because none of the models are in the volume" ... which is patently untrue. Any ideas? TIA

I cannot get 2.5 to slice more than 3 of a very simple part... it says 'unable to slice' because the models are not within the volume ---- which is untrue.

So the #2 failed. It did look like the nozzle was high though I think it layed the bottom layer correctly.... Since 2.4 is problematic, is there a stable release of Cura that you trust?

I'm not getting a completely filled bottom layer on this part. Is my bed too cool? Do I need a different pattern? The top looks fine.... The particulars are: 0.35mm nozzle 0.25 bottom line width 100% fill 235 deg nozzle 60 deg bed [/url][/img]

\I'm going to find out lol. I just set 2 parts to print, the first one went beautifully (I'm using TPU, and it's brutal). It just started #2 and it looks okay so far. One problem though was that when it finished #1 it dwelled there for a good 30 seconds before going to start #2. As a consequence I have a blob of TPU on the part. Any ideas how to get it to lift to retract height when it's done? TIA

Hola - I have a bunch of small identical parts to print. They are washers, approx 45mm x 35mm x 3mm thick. I want to finish printing one before moving to another. I know that when I duplicate them, I need to not group or merge them so that Cura sees them as individual objects. Not a problem. This is a long print job (15+ hours) and before I start I want to make sure I have the setting correct. Is there some combination of retract height versus part height I need to pay attention to so that it actually finished a washer before going to the next? Having it do one layer at a time for all parts leaves a lot of messy filaments. TIA

Cura 2.4.0... Under 'Manage Materials' I want to bring in the settings for TPU for my Makerbot M2. I select Import and browse to the loadpoint/resources/materials folder and select "generic_tpu.xml.fdm_material" and Open. The Import Material dialog opens and says "Successfully imported material file......." However, it does not appear in the list of Generic or Ultimaker materials. ?? TIA
