How do I set my second extruder to be the nozzle I wish to print from in Cura?

Sorry, I tried to take them as best I could, this was the best focus I could get at that distance. I can stand further back, but I'm afraid it may not capture the detail you want to see. i will try another print with the cool head lift on my next print and take pictures at a further distance. I have dual extrusion, but the extuder I usually use now appears unable to get filament into the PEEK insulator. I disassembled the print head and it looks like the PEEK is clean as is the nozzle, so im not sure why the filament is not feeding into it properly.

The resolution including the antenna looks better in the older prints (fan off), but the overhangs are much reduced in the newer print (fan on). Fan On Fan OFF Fan ON( left) Fan OFF (right)

I terminated the third shroud print prematurely because it looked like the exact same quality as before, but I can post the picture of the partial piece if you want. I wondered if it was just the nature of the shroud model, so I printed another Ultibot, since I have a few to compare it to. The brand I am using is Protoparadigm PLA. My travel speed is 150 mm/s. Should I alter my travel speed and retraction settings? Are the pictures below showing underextrusion? Here is the latest print using the mounted shroud (used supports this time, can compare to ultibot prints on previous page). Protoparadigm Brand PLA, .1 Layer height, 30 mm/s print speed, 220C nozzle, 70C bed, 100% extrusion, shell thickness .08, Brim turned off, Support type: Touching Build Plate on

I have dual extrusion, the reason I ask the default setting is I accidently bumped my keyboard when I had it highlighted, so it deleted the default numerical setting. What is the default numerical setting?

What is the default setting?

PMdude After looking at the shroud again, nothing is missing on the print. I reprinted the shroud at .1 mm, but kept all the other settings the same. The results: Exact same quality. So I decided to attach the new undamaged shroud to the printer. With the undamaged shroud attached to the printer, I printed a third shroud (also in PLA) hoping the cooling fan would improve the quality. The result: EXACT same quality. It does not appear that the fan improved anything. One odd thing I did notice though was that although I put 100% fan in Cura, when I look at the fan setting on my printer it says 255. Why is the fan shroud not improving the print quality? Do I need to tweak a setting?

Max Temperature Error One of the 4 assembly screws was contacting the thermocouple wire. The heat was then transferring to the wire and causing a faulty elevated temperature reading. It would get high enough to cause the Max Temp Error and shut down the printer. To resolve the issue, I turned the knob heads of the screw located at the top of the printer in a counter-clockwise fashion to raise them above the wire. Screw on the left is contacting the thermocouple wire. Min Temperature Error One my printer, the wires and plugs at the top of the print head were loose. Simply moving the wires to make sure they were tight, then tightening them if they were loose resolved this issue. Others on the forum have reported resolving this issue by making sure the wires plugged into the bottom of the printer were tight and completely pushed into the control board. For me, it happened to be the wires on top of the print head.

Macua85 I printed the same fan shroud in PLA that you printed. Same issues that you experienced, the shroud warped. I am going to try to print it in ABS next. As for the heated bed, I've also experienced similar issues in that regard. It seems approximately 110C is the max bed temp for the UMO. In fact, mine typically stalls at about 107-109C. I've had it set to 110C but waited 30 minutes and it still could not reach 110C. I will also post my results with the fan shroud when I get it printed in ABS.

What does the Wipe & Prime Tower setting do? What is the default setting for it?

I ultimakely want the shroud printed in ABS because I have read on the forums that PLA shrouds deform over time and will contact and damage prints. The ABS had very little friction when freely pulled through the bowden tube and there was no grinding.

Sorry, the bed for ABS was 105C, not 205C that was a typo (now corrected). My bed has difficulty reaching 110, it stalls around 107-108C even after 25 minutes of heating. The room temperature may be an issue for the ABS, my room temperature is 56 F. I will finish building my enclosure this week. Here is the latest PLA print of the fan shroud: PLA, .2 Layer height, 30 mm/s print speed, 220C nozzle, 50C bed, 100% extrusion, shell thickness .08, Brim turned off, Support type: Touching Build Plate on The shroud was printed on its side and this is the top. The final portion did not print, also the supports were very difficult to remove and I ended up breaking a hole in the print trying to remove the supports. Shell thickness .08, should I increase shell thickness?

Those prints are attempted fan shrouds, so the quality is so bad I can't even print a print shroud. In addition, one of those attempts above was ABS, my understanding is that fans should be off during ABS, so the lack of fan shouldn't effect the ABS print quality. There is a deeper issue that I need help resolving, so I can print the shroud.

PLA, .3 Layer height, 30 mm/s print speed, 220C nozzle, 50C bed, 100% extrusion

PLA, .08 layer hieght,30 mm/s print speed, 210C nozzle, 50C bed, 200% extrusion PLA, Cura High Quality Default Settings

My nozzle fan came in, but I cannot even print a shroud for it. I attempted to print with ABS for several hours and eventually got the printer to get a print going for 2 hours until it was no longer laying down filament and the result is the following: ABS, 240C nozzle, 105C bed. 30mm/s print speed, no hotend fan I need advice, why is my print quality in PLA and ABS so poor? How can I fix this?

Ended up ordering a 12v 50mmx50mmx12mm fan. I intend to print a shroud for it, hope this resolves my print quality issue.

Thanks, I ordered from dynamism, but ended up getting it through their account on Amazon.com because I had an Amazon gift card. I was very surprised by the $75+ price tag though.

Is there a USA based distributor that I can order Ultimaker brand filament from?

When I open the model in cura, it looks like the model on the left without the hand supports (grey/steel colored bot) pictured in your link. In addition, I did not turn on any support setting in Cura when I printed the model. Many I have talked to believe the lack of nozzle fan has a lot to do with my poor print quality. I will be ordering a fan tonight, any specific brand recommendations?

Could I get a 12v fan with 50 mm sides and 10mm depth?

Pm_dude Are you wanting a screenshot of the cura settings? If so basic, advanced, and/or expert settings?

After others viewed the video they concluded the printing path was fine. What I thought was printing too far to the right and left was actually the head attempting to print the ultibot hands. So far the consensus is the majority of the issues is lack of fan causing excessive heating on the print and possibly some overextension contributing to the issue as well.

I'm not sure which Ultibot version I am using, is there a way I can link the STL file on here?
