Bob I have tried a number of times with my UM2 with no success mainly at the beginning of the print, positioning and purging....would you mind sharing your start up script? Mel

Question what core do you use if you use HIPS...the AA or BB core?

Hi Bob That looks great!...Was this print done on the UM3 Can you share your start-up script. I purchased S3D a while ago and can never get it to work properly with my UM2. I would also like to use it on my UM3 Thanks Mel

Hello All Quick update, Erin from fbrc8 support saw my email I sent out late Friday at home, she took time out of her Saturday and went to the office and called me. She couldn't believe some of the pictures. Long story short after seeing the pics she walked me though how to access where the screws that were loose and reinstall them. Took about an hour. Thanks to Erin I'm up and running. Great support effort from fbrc8...

My original thought was it was an extra screw left behind but the more I moved the unit around more screws appeared. Again total of 5...the table is very very loose. Not worthy / capable of printing. I shot a short video with my iphone, not sure how to post it here....any suggestions?

Just received my UM3 When laying it on it's side per instructions to install the spool post (plug it into the bottom a couple of screw rolled out from under the build table. As I stood it upright more screws rolled out a total of 5 screws and the table itself it very loose. Not a happy camper. As anyone else experienced this? Not having a assembly manual it looks likes a some major disassembling is required to get to where these screws need to go...being the weekend all I can do is look at the machine. I'm hoping the re seller will swap /exchange the unit....

Hello Everyone Who can share information about Tinker Firmware. Does it have advantages over Cura? Is it difficult it install? Can Cura firmware be re-installed? Mel

I noticed this ref. past posts .....I do you adjust down?

cor3ys Much better....see pics

Thanks...I'll keep you updated.

Hi cor3ys I'm running the latest firmware, 15.02.1 Currently the shroud will actually go over the clip....I had to remove the shroud because I started the re-leveling process and didn't think at the time to take a picture to show the problem. As for the amount of clearance I would say a 1mm. So instead of lowering the shroud 8mm ......7mm would work better for me, not sure about others. I have a seat of Solidworks not sure if I can convert the STL to SW format to rise it, their's a limitation on file size / triangles SW will convert. What program did you use to modify it?

cor3ys I printed and install the fan shroud, but I ran into problem you maybe able to help me. When I went to re-level the print table the shroud be lower when the head comes to the front of the table it comes up to and over the clips that hold the glass down, thus not leaving any room for adjustment. Did you experience this if so what was your fix / work around.

Thanks for the feedback, did exactly what swordriff described......bummer on the sensor...it's still good just stuck in the past.

OK I received the new blocks and nozzle....When switching to the new block the heater cartridge released / came out with no problem....but the temp sensor didn't. I do two spare....problem is how do I thread this back to the control board under the UM2....Is there a certain procedure? Is there a easy way to do this. Please advise...thanks in advance.

I'll take two....just let me know when they are available states side. I'm in Texas Mel

What I would like to know is where is the dual extruder?

Thanks for the feed back.....Album set to public.

Does anyone know what this extra wire / plug is for?

Hello Looks like Markus had the key comment, well it worked for me, that's is doing the "factory reset" after doing the update. Everything is running fine (14.12.1), currently in a 8 hour print nearing it end. Thanks

Hello I received this error message after updating the firmware to 14.12.1 from 14.09. After restarting UM2 and trying to print again, again the error message. On my third attempt after the printing started I went to the tune option and selected the temperature and watched it....my setting was 225 and it steadily dropped to 217 then the error message came up 8 deg difference. So then I decided to re-install version 14.09 firmware. Started a new print set at 225 no problems. I do want to mention after starting a new print with 14.09 and switching to the temperature to watch the temperature it was having a 8 deg. swing above and below my 225 but no error message. After a while 10-15 minutes of printing the temp finally stabilized within 1 deg. What I don't know was that temp swing always there from the start? Also I just finished an hour print with no issues. A question I have is, does the new updated firmware have a tighter tolerance causing the error message, and second at the start of the print should there be that much of a swing in temperature? Any thoughts?

Thanks for the feedback, the interesting thing is I'm having this problem with Ultimaker filament...I will look into Colorfabb.

I'm a newbie here, I'm been looking the forum and have not seen anything mentioned about a problem of filament getting tangled up on the spool, especially on long prints. I have several prints of 10 hrs. plus and have trouble completing them because the PLA being springy as it unreels the filament will cross over each other and eventually become tangle over time. Doing a print unattended for me is a challenge. Any suggestions how to correct this, (keep the material from getting tangled up). Thanks ...any feedback will be appreciated. Regards Mel
