It's not a pop up message. Just shows under one of the text fields I think when entering the API or something. Can't check now, not at computer.

Yes it would be nice to have a set up guide. It was mentioned in 2.6 beta that you don't need to set up Octoprint. All the settings are sent from CURA. I would set it up to auto connect though so you don't need to enter Octoprint to connect it to the printer. You change the flavor in configure machine in cura. There are 2 reprap options. I just selected reprap marlin. As I said above it prompts you to change this when entering the Octoprint connection settings in CURA.

When you are setting up the Octoprint settings in CURA it prompts you to change the flavor to reprap or it won't work.

Here is the link to the guy who came up with this. hwttp://www.engineerination.com/2015/02/drv8825-missing-steps.html?m=1

I have also been wanting new features like notifications when print is done with a photo of the completed print etc. But yes it does sadly look like it was abandoned.

Print times can be discussed in a different topic. But it depends on your printer. Some can print faster then others. You will quickly learn printing is not a fast process. Just start your long print before bed then when you get up it will nearly be done and it won't feel like it took so long

You can view any gcode file using any notepad program but I would recommend using notepad++ You can also name your files before saving them or save them as a project. Project files save all the print setting and even the part location on the bed. So if you open a project file in CURA you can then see how you printed it.

The temps may also be different as the hotends have different heat zones and are made quite differently.

I think there was a bug with this and "centering the camera when model is selected" setting is greyed out under "configure cura". I know some work has been done for 2.7 but not sure of it progress where it will zoom in the direction of the mouse pointer.

This Info would be best if it was in the header of the Gcode file. It currently has some info but not all like what you are wanting. Otherwise, long file names can be cluttering to read.

Is the UM2go the Best of the UM2 serries? Well, I certainly think so, So why are people opting for the UM2+ and UM2extended+? SIZE! when buying a printer you look at the size of the build volume, You sit there with a rule in your hand thinking how tiny they all are. A UM2+ can only print 200x200 that just seems so small. So why would anyone ever want something as tiny as the UM2go? I first started off with a UM2 a few years back and printed lots of things some big, some small. but after a while I realised most prints go no way near filling the build volume. Then The UM2go hit the market and within minutes of its release, I placed my order. Out of all my printers, it has by far the most print hours. Once I started printing with it I just loved it and found 90% of the things I print from phone holders, gadget repairs, prototypes and toys all fit within the build volume. Some max it out but you would be amazed at what you can actually fit in the little sucker. UM2go Vs UM2+(extended) Well, there are a few shortfalls in terms of features but these can be remedied as I will explain later. The UM2go just has a fixed nozzle size at 0.4mm, The most common but the versatility of the Olsson block in the UM2+ is a big plus. Also sadly it never came out with a heated bed or geared feeder. but there are some positives, It's just so cute being one. When you first open the box for the first time you can resist smiling. The Price is a lot more affordable than any of the other UM2 series printers and the carry case is really handy. Most people won't need to take their printer anywhere but for those odd occasions where you want to take it into work or to see a mate who needs some parts for a project, it makes it such a breeze. But the main benefit is the print quality. The rigid little frame, short rods and little print bed allow it to print with superior quality than its bigger brothers. This means you can even crank up the speed a bit which is what you really want on those outings. Carry Case The carry case is very well made. It's really sturdy and can take quite a knock without damaging the case or your printer. There is a 2 go backpack kit so you can wear it on your back. Looks weird I know but its surprisingly comfortable. It also has space in the case for all your supplies so you have everything you need as an all one one package. If you want to kit your case out, even more, you can with some neat things like a carry handle, Wheels and even a Cup Holder. Upgrades Number one upgrade for this little beast has to be the Heated Bed Kit from the Gr5 Store. If you are one of these people who only print with PLA then you can live without it but really. With it, your life is so much easier. Next is the Extrusion Upgrade Kit, Back in the day there used to be a printer called the UM2. It was much like the UM2go but Bigger. Well, this extrusion upgrade kit fixed a lot of issues that the UM2 had. Even though it's not officially supported for the UM2go you can still make good use of it. This will give you the Olsson block, better fans, Better feeder and more reliability. To fully make use of this upgrade kit I have designed a feeder housing that you can print so everything still fits inside your neat little carry case. I have also made a machine profile for cura so you can get the full UM2+ style experience. even after all of these upgrades it still comes in a few hundred dollars short of getting a UM2+ But there are a lot of other things you can do on a budget like print a Fan Shroud, or some other options and many feeders to choose from like the popular Bondtech. UM3 style Wifi can also be achieved using a Raspberry Pi running Octoprint with the Octoprint plugin in CURA. So, Should I buy One? Yes, you Should. If you are just starting out then this is a great little printer at a lower cost. It also gives you options to tinker and upgrade it to make this great little printer even better. If you already own a printer then you should consider it as it's a REALLY good second printer. Leave your UM2+ or UM3 doing all the big stuff while your Little UM2go can chug away on all the little stuff.

One issue I am having, The Start Gcode works fine and it will print but if I need to abort the print it doesn't Home the head or anything. It will just sit in place. Also, you cannot tune any settings on the actual printer as it just displays Printing with USB.

I did not change any of the settings in octoprint. Did you set your printer gcode flavor to RepRap in CURA machine settings?

It has be mentioned here on the forum by a UM employee that a range of Cores will be available of different sizes. This may or may not happen and they delay is not in making the core but in creating good user profiles for all the materials. Aftermarket ones work great but you have to experiment yourself to create a good profile for the materials you want to print with. Or you could wait and hope UM releases a 0.25mm core.

It maybe that your printer is underextruding slightly? And not CURA. What printer do you have? How many print hours? What material are you printing with?

Nope. I have the same problem and it's really annoying.

No you don't need to make different ones for fine,normal,fast. It's automatic. If you create a material, the temp will automatically change depending on if you select fine,normal,fast. So if you create a material and give it a temp of 200deg but select fast, it will change the temp to 210deg.

I just set mine up. Followed the video on the octoprint download page.to set up my raspberry pi. I used the Pi camera with a long cable. I had a bit of trouble with the API, I found it's best to scan the barcode with your phone and use the number that shows as on my computer I couldn't see all of the numbers in the code.

In my experience PVA likes continuous flow and not small towers. I play with horizontal expansion a bit and some models work better with more. Some can get away with less. If some sections of PVA are small it can underextrude and can easily break. Increasing horizontal expansion can also help with PVA adhesion to PLA. But all this is model dependant.

You need to create a material profile for every material you have or make a default PLA profile for example and when you change materials you select the same default. Or you can select from one of the default CURA materials and edit one of those. The Material Temp in the materials manager is a base temp. this has an offset when printed at different layer heights. I'm not sure what the base is. maybe 0.1 layer height. So make sure that you desired temp at a set layer height works with this offset. For example, if you set the material temp for 200deg at 0.1 layers then if you select a printing height of 0.2 then it will offset the temp to 210deg.

I haven't tried using layceramic. But you can set different temps and other print settings for both materials to get great results for both. This is something that you would need to experiment with. I would just check to make sure that the filament is not abrasive before using it in a standard UM core or it will not last Long. You could use a hard core from 3D solex and use an everlast nozzle if you find it is abrasive. Also PVA may not stick to layceramic. So requesting a sample might be a good idea just to check.

It should provide a brim around both items but by only one extruder if they are both on the glass. even if its 2 models merged as 1. In the pictures above there is no brim around one item but it also didn't even print the first layer for that item. So it should show brim around both and a first layer around both on layer 1.

The 0.8mm cores are also available.

It must be your lucky day. UM just put their UM3 door on the website. https://ultimaker.com/en/resources/49779-installing-the-advanced-3d-printing-kit-for-the-ultimaker-3

Yes, you can print with one material and it won't fault if only one is installed. You must have 2 cores installed though but it doesn't matter as it just sits there. I currently have my printer at home while I am at work, printing with one spool of material loaded and printing with just one core. I can also view the camera via a VPN. there is a very good easy to follow tutorial Here on how to set one up so you can remotely view you UM3. Will UM release a front door? I am pretty sure they will. They made one for the UM2+ so you can print with some of there harder to print materials so I am sure one will follow soon. If you notice that CURA now shows 0.8mm Nozzles and there has been a mention by someone from UM on the forum that it will come SOON. (up to you to decide how far away soon is, 6months? 2 days? I dunno) I don't know about other sizes and if they will ever make a 0.25mm one. Let's hope so. Yes, you can use 3Dsolex cores and UM cores together and yes they work with auto leveling. Some people advise against auto leveling but I always use it and it's been great. My advice is if you want an easy to use printer, can afford it and are not deterred by the price then get the UM3 despite having to wait a bit for some extras.
