When is the .06 nozzle going to be available for the UM3? Use almost extensively on 2+ and 2+EX and they work great. I can run down to .04 layer up to .1 easily with awesome quality. Love to do the same with UM3. I have ran .08 on UM3 but quality in prints has suffered a bit, although the support runs excellent with .08 nozzle.

Thanks! Wait for update.

Is there a way to turn off the 2nd extruder and only print in single material mode with the UM3? The PLV gets hot, and plugs up. I have unselected the "enable support" box but still gets hot. Need to purge or atomic purge the nozzle before I use it every time. Many prints don't require support so it would be nice to just make sure its off.

What is the PVA minimum clearance for assemblies on UM3 when designing assemblies? I am adding holes into the assembly for water access to help facilitate support removal but after a few tries have had little success on movement after print is complete. (Last try was at .010") I currently run a Stratasys polyjet that can go down to .006" (.15mm) from wall to wall or .012" (.3mm) on diameter. Run almost exclusively at .06 layer resolution - high quality.

Have the CAD files been released for the UM3? Specifically looking for nozzle assembly.
Thanks,
James

The UM2's are not physically connected to computer. I save to SD card for them. Cura does have all three machines loaded into "machines" and I select whichever one I am using. The UM 3 is connected via LAN / network but still asks "allow user" on machine every time I try to print. Evidently, the connection access is getting lost. (Have not shut machine off since it has started running jobs.) Does a great job of printing! I remote in to my computer a lot and would like to start the UM3 when I am not physically on site. I leave machine cleaned and ready to start before I leave for the day.
Is there a setting in Cura that my be off? Something I missed on setup?
Does Cura need to remain open to maintain the access? Or once Cura is closed does that reset the access?
No. Cura saves the access with a machine added to Cura. So if you have 3 machines, Cura should also have 3 machines added. Each of those (virtual) machines in Cura can then be linked to a physical machine.

I currently have 3 UM's (2 - UM2+'s and the 1- UM3) running thru CURA. The 2+'s run on the SD card and the 3 is hooked up thru LAN. I switch settings depending on the machine I am using. I am the only one with access to my machines and they are clear. I remote into my system, build / slice the job or part and send to the machine. I have cameras within my office to verify everything is good to go and would really like to turn the "access" request off or ON permanently. Seems like this should be a simple code switch. Would be great if I could select the access form the computer sending it.

You should only need to confirm on the printer once for every computer/cura combination.
Not quite true at this moment: I agree that I don't have to go the machine and allow access to my Mac every time I start Cura, but every now and again I have to grant access to my (same) Mac again. Don't know why, not a big nuisance, but indeed it would be convenient if the UM3 permanently remembered that access was granted. Small bug perhaps?
It should do this. If it forgets it, it might be a bug (either on the printers side or on the side of Cura)

I have purchased the Ultimaker 3 and really like the network capability. I would like to be able to remote start the machine without being next to machine. I can dump program from Cura, but when I select the UM3 it asks me to allow access to the machine. Is there anyway to turn this off so I can print directly to the machine without an "allow" to be pressed on machine first? I can see the machine in the camera and know it is clear. I setup the machine before I leave for the day (along with other machines) and would like to remote start when jobs come in last afternoon or after hours. I can remote into my computer and start other machines and would like same access to Ultimaker. I can also get text messages or e-mail when jobs are complete from the Stratasys machine. Are these options in the future?

By the way the tinker firmware is awesome! I love it. It's so easy to use. It has amazing features with better leveling control and ability to resume a failed print. You can adjust PID values right from the menu and much much more.
THANKS! Asked about resuming a failed print and was told not possible. Downloaded .hex file for my um2ex... stupid question, how does it run? Is it a plug in?
got it.... nevermind

Well the only reply I got so far is from Simon at fbrc8 (he's very smart). He mentioned that the PID values are tuned for a 25W heater and my um2go does oscillate a bit in temperature but I don't mind. The quick fix is to lower the 3 PID values by the ratio of 25/35. In theory this is the proper values for PID. In practice you can run the PID autotune feature. If you already have tinkergnome Marlin installed you can edit the PID values there easily. Alternatively there are several easy tools to play with PID settings for your print head. But again, the default values for the 35W heater are good enough for me.
Thanks, I will be upgrading my 2EX to the 2+ kit shortly and purchasing another 2+ printer. Is the tinkergnome a free download? Haven't gotten into this yet. Be nice to see code.
-
lol. That's strange since my understanding is that the UM2+ kit includes a 35W heater. I haven't gotten my upgrade kit yet but it should arrive soon. I have no idea why they would say that - I wish they were more explicit. Was this UM support in Netherlands? Or UM support at fbrc8? I guess I can ask them all directly. I'll do that as they all subscribe to he same chat group that I'm a member of. Will get back to you. However I have the 35W heater in my Um2 and a 39W in my um2go but haven't changed the heater in my um2ext yet.
fbrc8... Joseph and Erin have been helping me.

Spoke with UM support and they said the UM2 EX is not compatible with a 35W heater. They did say it is exact same size but programming does not work. What are your thoughts?

@jlarson - I'm confused. Maybe I read your posting too fast the first time or maybe I misunderstood. When I saw "um2 extended" I think I was thinking "um2 plus". The plus comes with 35W heater. The older one comes with 25W heater. 25W heater works good enough for the most part. You should be able to work with that. But if you installed the olsson block and are now getting these heater errors then the actual problem is more likely that the block is touching the fan shroud. Loosen the 4 screws holding the fan shroud and it should move slightly up and down. If not then the block is probably touching it and you should raise the block by tightening the round steel coupler nut. You can do this by removing only the long thumbscrew - front left one and sticking something into the holes and using that tool to rotate the round nut. But only do this while it is hot - 160C is a good temp - just in case some filament got into the threads. You want the block pretty much all the way up excelpt maybe back off 1/2 to one full turn.
Or maybe you don't have the olsson block?
Actually running a custom cooling block. (I printed) not touching olsson block. I did reduce fan speed to 50% and it is working. Yes, older UM2 ex (not a plus). Watched part print in "tune" screen and could see temp drop with ramp up with fan speed increase. reduced fan speed with each ramp up and the heater can "keep up" to programmed temp. Looking to upgrade to the 35W heater. Thanks for the reply!
-
Actually think that may the problem. Think they sent the 25W version. I reduced my fan speed to 50% AND watched the temps in "tune" screen to verify what the temp was doing. As Fan speed kicked up in program, the temp fell. I reduced fan speed each time it "ramped" up and temps would return to normal (Programmed). So far so good, print quality is looking pretty good but seems I'll just have to replace with high wattage or reduce fan speed with higher temp materials. How much is higher wattage heater?
What wattage heater did they send you? Make sure you get a 35W heater - that's what is in the new UM2+ printers. 250C is a little harder for the heater to keep up with. Personally I just turned off this error on my printer . This test didn't exist for the first year that the UM2 was out.
You can test the wattage of the heater by measureing the resistance with an ohm meter (with power off and heater not connected to power). Formula is Wattage=24V * 24V / resistance
So for example 24 ohms would be 24 Watts. What country are you in? I have 35-37W heaters - if you order my store include a note that you want on the high end. 3dsolex has 35W heaters and I think even 40W heaters.
Is there a way to block the fan from blowing on your olsson block? Is this with a large nozzle where you are printing lots of material fast e.g. .8mm nozzle? Or just regular .4mm nozzles. Some people block the airflow around the block using kapton tape or other wind-blocks.

I have UM2 Extended, running Firmware 15.04.3ex and getting heater error. Looks like it happens about same time (3rd or 4th layer into print) Shuts down with error. Support sent me a new heater but nothing. I did manage to print a robot as I have been trying to figure out what is going on and did not want to start my part unless thing is working. I am running Ollson block and custom printed fan shroud but have switch back and forth between original and printed fan shroud and does not matter. (errors on both) Stuck! Any ideas? Running material colorFabb XT (grey) using below:
[material]
name=CPE
temperature=250
bed_temperature=65
fan_speed=50
flow=100
diameter=2.85
Was going to increase fan speed up, but errors prevent from seeing what going on with overhangs.

Has anyone complete for UM2 Extended? If so, how many segments?
UM2+ and 2+ extended firmware updates crash table into noz
in UltiMaker Cura
Posted
I updated firmware this morning on UM2= and UM2+Ext. The UM2+ extended crashed into nozzle after upgrade. I calibrated table and problem went away. I started UM2+ and crashed into nozzle, also. I calibrated table and keeps crashing. The heater core on my 2+ext is out and have ordered a new one, but now my 2+ is down, also. NEED FIX to FIRMWARE ASAP!!!
Thank you,
James
