I was hopeful, but it didn't work.. The section of the file now reads: def _updateThread(self): while self._check_updates: result = self.getSerialPortList(only_list_usb = False) self._addRemovePorts(result) time.sleep(5) But on the right, I am still told "Not connected to a Printer". Cura 15 shows the middle icon as "Save Toolpath" until i switch the printer on, where is immediatly changes to "Print USB" But nothing I have tried in CURA 2.X allows the printer to be shown as 'connected'. Any other suggestions would be welcome...

I am not insisting on anything.. But am just a little confused as to whether I am missing something.. Nallath even implied that the printer should be seen, which is why I don't want to give up. If it doesn't work, I am happy with that... But I don't want to stop trying, if SOME success is possible. As I said, I have had a flawless experience with USB printing in Cura pre 2.X, so just want to try. If CURA 2.X had no USB print support at all, I wouldn't ask.. But it has and I would like to try... Thanks for the tip about changing the config.. I will try that tonight...

I am still not clear whether we are saying that Marlin based printers should work, or not... I went back to CURA 15 to see what difference there was and remember that under "Machine Settings" there is a Serial Port and Baudrate setting But in CURA 2.X I can't find this option. I don't even get the feeling that Cura is "looking" for a printer, and wonder if I am overlooking an obvious setting?

Cheers.. I accept that it might or might not work.. But I can't even get Cura to see the printer. Even when its on, it just says "Printer Not Connected", where as in Cura 15, the icon changes from Printer to Save G-Code as I turn the printer off and on. Any ideas how I can even make it see the printer?

Maybe I didn't explain myself (or understand your reply).. I have no problems with USB printing.. I never have.. Its been flawless on several PCs and 1000s of prints. And I still (happliy) use Cura 15.. But was pretty sure that Cura 2.x dropped USB print support, so I never tried.. But I am jealous of some of the new features and decided to give it a go, just in case. But the Printer button at the top, doesn't even recognise the printer (no surprise really) and my fears that USB printing to Marlin/Reprap printers has never been implimented. I know I could use Cura 2.x to export the GCode, but I can't be bothered.. I just love the way I can move/alter/adjust and print from Cura 15 in real time and the whole process of exporting Gcode (Which I have done many times before (And used Repetier to print)) is fine, but annoying. So I will just carry on with Cura 15 which has served my perfectly.. But I just wonder whether there were any options (even unsupported and experimental) to impliment direct USB printing in CURA 2.x on Marlin based printers..

I finally decided to try CURA 2.X with my Printrbot and as I feared there doesn't seem to be a way to print via USB. The Print button at the top just gives an error saying something like "Printer Not Detected"> I know that the devs don't like USB printing and have stated many times that its unstable... But in the older versions of CURA, I havn't had a single problem what so ever and i love it... Is there any way to do USB prints from CURA 2.x? Even if its unsupported?? My fingers are crossed, but I fear I am going to be stuck with 'old' Cura... Jon

Do Doh.. I am officially an idiot.. I corrected several syntax errors and typos.. But I completely overlooked that comma. Its working now and for anyone who is interested, the correct values for the Printrbot are: "file_formats": "text/x-gcode", "platform_offset": [0, -3, 0] },

Cheers for that.. I checked the "printrbot_simple.def.json" and there is no "platform_offset" variable.. But I checked another json file and can see the syntax.. So I added it to the Printrbot json and now I can't see Printrbot in the list. There must be something about the syntax that I don't understand. I changed this: "metadata": { "visible": true, "author": "Calvindog717", "manufacturer": "PrintrBot", "category": "Other", "platform": "printrbot_simple_metal_platform.stl", "file_formats": "text/x-gcode" }, to this: "metadata": { "visible": true, "author": "Calvindog717", "manufacturer": "PrintrBot", "category": "Other", "platform": "printrbot_simple_metal_platform.stl", "file_formats": "text/x-gcode", "platform_offset": [0, 0, 0], }, Any ideas?

I adore CURA 15.x, but I decided its time to have a good look at the "new" Cura. I installed 2.3.1 and was happy to see the option for the Printrbot Simple... But when I load an object, the bottom few millimeters appears inside a layer of "fog"... Like the object is under the bed... Moving the view around, it looks like the Printerbot bed is rendered accuratly (Which is nice), but the print surface is under the bed... So I am pretty sure its just a visual thing and it won't affecting slicing/printing.. But its annoying.. Has anyone else noticed this? And is there a solution? (perhaps a way to remove the rendered image of the Printrbot bed?)

I couldn't imagine not being able to print directly from a PC.. I have used all of the 'old' versions of CURA on several PCs, and have never had a single problem with USB printing.. Infact, I have been amazed how stable it.. No matter what else I do on my PC, it never fails.. Infact, in recent weeks I have had a problem with Cura/Python where it freeze and yet it still finishes the print, even though the Print Window and Cura has frozen. I would just find the whole 'write to SD card, take it out and pop it into the printer' so unbelievably restrictive and frustrating.. I want to keep doing what I am which is to use the printer, like a printer and print from the PC. So I guess my next question is, if I bought an Ultimaker, what version of CURA would I have to use to keep using USB printing? Would I have to stick with the 'old' version like I have.. Or does the new version how have USB printing (Albeit unsupported)?

I am a Printrbot user and love it.. Its been faultless for years and never caused me any trouble. But I have been running a little 'business' and have made well over 1000 parts over the past 2 months, and am now worried that my little Printrbot may not survive, and frankly I would just like to invest some of the money I have made on a new printer. I currently use the 'old' CURA version and print directly via USB and havnt' had a single problem in 2 years (even though its been suggested that USB printing is flawed). As such my next printer must have this option... Am I right in thinking that the 'new' CURA versions do not support direct USB printing? This is the primary reason why I am still running the old CURA. A logical choice of printer is an Ultimaker.. But what options do I have if I want USB printing.. Do any of the Ultimaker models allow this, and which version of CURA would I have to use to make this happen. Thanks for any info you can give Jon

Cheers.. After over 500 prints, i can't believe I just noticed this now

I have printing almost continously for the past 18 months using the "old" versions of Cura and still use 15.04.3 Today I am doing a job and am inspecting the layers and have noticed something that I have never spotted before... The "fill" is usually a grid.. But in my case the fill a series of diagonal lines which alternate by 90 degrees on each layer.. So you still get the 'grid' but its formed over 2 layers. I am 100% sure it used to be a grid.. So I did a few tests and found that upto 24%, I get the grid.. After that I get the lines. Is this right? Has it always been like this? I never never noticed it before.. I am sure that its OK, but I thought I would ask, as I have never noticed this before and since the job I am printing today is 10 hours+ and needs to be done today, I thought I had better ask. Jon

I am using Cura 15.04.3 and have a print which has 398 layers.. | want to look at a flat part of it on layer 25, and am using the "single layer" view.. When I move the slider up and down, I can get to 24 and 26, but not 25. I am sure layer 25 is there, but this appears to be a quirk of how the GUI works... Is there any way to get to this layer? Are there any "hot keys" which will allow me to go up/down through the model? Jon

I have just printed a small box with a lid which fits inside the box and can't get the lid to fit.. I dug out my calipers and found a really obvious problems.. The walls are simply too thick. The walls should be 1.5mm, but they print at almost 2.0. I double checked the STL file and confirmed the walls are indeed 1.5mm.. And then I checked again in CURA and again confirmed the walls are 1.5mm I am still using Cura 15.02.1 and have a 0.4mm nozzle and am printing with a 0.8mm shell thickness. Any ideas how to make the wall thickness closer to 1.5? Jon

i read a comment on another forum and then i assumed you confirmed it above. I am sure it does something as the "cost" (and lengh of filament used) changes when you alter the flow. So my wuestioj stands.. would the flow have the same effect as changing the Steps per mm? I just want a dynamic option i can easily change to do some tests.

I am getting inconsistent results to my measurements of the extruder so have been unable to calculate the correct value.. But I guess if I make a note of what it is now, and crudely make adjustments (Without doing the maths) I can see the effects of under/over extrusion. What exactly does "Flow%" do? WOuld that not cause the printer to extrude less/more than it should? Jon

I am using Cura with a Printerbot and its been flawless.. But my Hot End has been jamming frequently causing my extruder struggle and I decided to change it. I originally planned to go for the UBIS Metal.. But after ordering it I read a lot of horror stories so in the end bit the bullet and went for an E3D. Problem is, I am now getting terrible prints.. When I get the nozzle set low enough for the job to stick, it then scrapes/scratches the job as it prints The theory is that I am over extruding and wonder if there are any settings I could use in Cura to experiment.. I assumed the "Flow %" value would do it, but I have read it does nothing. Is there an easy way to reduce my extrusion rate to see if I can get this under control? Jon

I tried messing with the base value, but even at 0.0 it leaves a "plate" at the bottom.. So I just used the "cut the bottom" feature to get rid of it and that works. But your point about the zig-zags is absolutely right.. I have looked at the layers and its horrific.. If I try to print that, its going to shake my printer appart.. So I think I need to look for another solution. I will have a look at PS, but I am a novice and know almost nothing about it.. So I fear I may have to hunt for another solution.. Cheers Jon

That is AMAZING.. I have been using Cura solidly for 12 months and didn't know that... I am going to have a play.. But based on my first tests, this looks perfect. One thing jumps out immediatly is the 'base'.. My "background" is white.. Yet I get a bottom to the print which could have to be trimmed off... Is there a way to make Cura treat a white background as "nothing"? Jon Edit: I guess I could just use the "cut off the bottom" feature to sink it into the bed.

I do not have an Ultimaker, but I do have and use Cura and I just wonder if someone is able to help me. I am currently doing a little 3D printing project at work as a favour and one of the senior managers asked me if I could turn a small drawing from their daughter into a 3D print. I know its possible, but have never tried and before I spend hours researching, I just wonder if anyone has any info they could share. Does anyone know of a good guide or tool that might help me? Jon

Just noticed that the bug where double clicking does not open a file is back in 15.02.1 (With Win7) You can open the first file and it launches CURA, but when you double click on another file it doesn't open.. This is actually a worse state than before, as that bug allowed you to open TWO files before it stopped working. Jon Edit: Just tried on another computer and its fine.. So then I looked at my task manager and I had 4 Pythonw.exes running.. Killed everything and now its OK again.. Not quite sure how I had multiple instances of Python running.. I need to monitor this to see if it re-occurs. So for now, just ignore this.

As you are running 14.12.1, just get the 2 files from the thread I posted above and you can have the functionality you want....

Probably not worth starting this disucssion. It got quite heated last time and once one of the team wrote a fix, but Daid has strong feeling about this and it never evolved into the current versions, Here are the details http://umforum.ultimaker.com/index.php?/topic/8574-cura-autoslicing-poll/ I am sure if you put a post in thwt thread asking this, someone will might update the "fix" so its compatible with v15

One of the devs wrote a fix for this in a previous release (i think it was 14), but Daid is dead against this functionality, so it was never added into the product. So you can have this functionality, but you will need to run an old version. I just looked back at my old installed versions and this was available in 14.12.1.. You simply had to replace the modified "sceneView.py" and engineResultView.py" files..
