Hi fergazz These are my settings that I used the other day with good results. Bear in mind I have UM2+ and had my extrusion multiplier set to 0.95 instead of 1. Also I was only printing at 30mm/s. You could see if these settings work for you and then add more temperature and speed as desired.

I have already upgraded my printer with the |Robert| feeder, an Olsson block hot end with a 30 watt cartridge, and 3dsolex high temp PTFE coupler. Is the included stepper motor different to the UM2 motor? My setup should be able to print at much higher speeds. Even at 35mm/s effective extrusion rate (20mm/min extrusion -> 35mm/s @ 0.4 width, 0.15 layer height) there is under extrusion in the 100mm command. The UM2+ feeder is geared.

I think this is typical characteristics of the the um2 feeder and umo even though there is no noticeable slippage or skipped steps. The upgrade to um2+ greatly alleviates this problem. Other things to do is make sure you have a clean nozzle, have an easy unrestricted entry into the extruder, have the tension adjusted right on the extruder, check the ptfe coupler in your hot end and then always print at a moderate speed like 25 to 35mm/sec.

You should be able to heat the block up with the printer without the nozzle in their and then use your needle again to clean the block.

Try turning the print 90 degrees on the bed and see what happens

Thanks Owen! Printing closer to the plate seems logic, but how to set that up? I know how to calibrate the plate by a piece of paper. But how to measure, if I want to get even closer? I will definately try to increase the flow, that seems very promissing. I didn't know, I can do that for just one layer!? As for the nozzle, I only have the standard (0.4 mm), using PLA at the moment. Regards. Uwe To get closer to the the build plate, after you do the standard level tighten each of the 3 bed levelling screws by the same amount. 1/8 to 1/4 of a turn anti clockwise when looking from the top. Sorry I see Cura doesn't allow to increase flow on the first layer (I used Simplify3D). You could add a line of gcode at the start of the first layer to increase flow but I would try without that first. Getting closer to the build plate should have the same effect. 0.4mm nozzle should be OK. You seem to have fairly big text.

It looks like you need to print closer to the build plate. Then experiment with a thinner than usual first layer plus increase the extrusion rate for the first layer. Also make sure your text is deep enough. I have had reasonable results recently with 0.1 mm first layer, 110 % flow for first layer (but 100 % may go ok too), 0.7 mm deep text using glue stick and printing with abs through a 0.25 mm nozzle. Hope this helps. Good luck. Owen

Hi, Firstly preview your print in Cura to see if Cura is not printing the whole file. Next get the latest version of Cura and preview in that. If Cura is not showing the full print then upload your file and Cura settings here. If Cura is showing the full print then maybe you are having an extrusion problem. Let us know how you go and maybe upload a pic of your print here first. Owen

I used one of these temperature controller on ebay With a fan to remove the heat. I set it to 45C for ABS and tall prints are much better. I just have the top enclosed and the front.

I get a rattleling sound as well. Do you you think it could be from combing?

try printing 2 at once and use 100% fan

Hi Owen, is it possible that you can create a short screencase of this and send like a dropbox link in a DM to me? (Or whatever you prefer?) That might help our developers too. Thank you for your help! Look at my post, just above yours (https://ultimaker.com/en/community/11734-general-forum-feedback?page=52#reply-155829) and you can see the behavior described Yeah, I think you're right.

Hi Owen, is it possible that you can create a short screencase of this and send like a dropbox link in a DM to me? (Or whatever you prefer?) That might help our developers too. Thank you for your help! Screencast do you mean as in a video? Just clicked on the unread link now on my phone and it went to "https://ultimaker.com/en/community/11734-general-forum-feedback?page=51#unread"

I just refreshed my list of unread topics. The link to this topic said "1 unread" but the URL it pointed to was "https://ultimaker.com/en/community/11734-general-forum-feedback?page=unread#unread" which made it jump to the top of page 51 instead of the last post of page 52 When it's working the link would be "https://ultimaker.com/en/community/11734-general-forum-feedback?page=52#unread" Hope this helps. I'm on firefox on Win 7 Ultimate Owen

This, all the time. Still not working all the time. Why? Could both @Lepaul and @titus tell me what browser and operating system you use? Do you have multiple tabs open, so a read-command can be triggered without using the notification under the bell? Thanks! Probably related to this. When showing a list of unread posts(just refreshed), clicking on unread posts link takes me to last page top post. Scrolling down to the end doesn't show the black bar indicating the start of the unread posts. This had been working for several weeks until a few days ago. Samsung tablet. Google Chrome

Also you can raise your travel speed to reduce stringing.

Hi You look like you have under extruding happening there so you need to find out why and fix that. I have been printing xt at 240c with fairly good results at 30 to 35mm/s that was before the new um2+ upgrade. Which printer do you have?

Gooday Les Would the pewter be too inflexible? Hard for the bowden to bend and then push the pewter through. It would be awesome if you could though. Owen

Hi You could have more clearance over the total length like 0.5mm less for the width say .2mm and .1mm over the thickness. Maybe ABS, XT or NGen as they have more flexibility than PLA. Nylon could be good but I'm not sure how easy it is to print. For thickness maybe go a multiple of your nozzle width. So for a 0.4mm nozzle try 1.6mm for sides top and bottom. Good luck and show us the final print.

When you put those stepper drivers in backwards it destroys them, I've proved it more than once;). So you probably have 2 crook ones now.

yep

I think they recommend 100 to 110 for the HB temp so maybe give 110 a go.
