Does anybody know if its easy to change the location on the printbed for this test? Would like to see the impact of friction in the bowden tube (how much its bend). So print one in the left-back and front-right...

I was alway using a piece of paper for this at startup. .. but since cura 14.7 its massively improved. Oozing takes place in the left front corner with a raised bed... no more chunks of plastic in my first layer. @daid. Thanks for this. Like it a lot.

Sure. Pub on Saturday evening ? I'll leave my wife & kids at home....

I just use the pause function on the printer. You'll need a feeder you can open. Like roberts (or my derivative)

I print XT without any spray or other stuff, just a good clean bed of 70 C works fine for me.

@ spirit ; looks good... like it that you're sharing your development history!

I see no reason why you could not use a UPS, http://www.apc.com/products/family/index.cfm?id=27&tab=models think an UM2 runs at about 200 W ....

In general when you need to now details on components its easy to start looking at the design file (STEP) of the UM2 ( https://github.com/Ultimaker/Ultimaker2/blob/master/Assembly%20UM2%20stepfile.STEP ) You can open the STEP in Design Spark Mechanical, and even modify it ( using this trick > http://umforum.ultimaker.com/index.php?/topic/2772-spaceclaim/page-3#entry53816 ) You can look into the STEP file to find the partnumber of the part you'r interested in. When you then look at the PDF of the partnumber (also on github) you can sometimes find additional info. In the case of your connector question, the drawing of the fan (part 1330) does not contain this info, but if you look at the other cooling fans (B1313-ZIP-A) you'll see its a JST XHP-2 (they look the same to me...)

Robert: I really like the transparent instruction picture with support in red... what software did you use?

ha ha ... nice edit ... by the way, I keeps things fairly simple .... the back plate I'm making is an add-on to the back off the printer. I try to do only things that can easily be reversed.... so no drilling or cutting in the UM2 .... probably the only thing that may scare off some people is taking the feeder motor out of the printer...

http://umforum.ultimaker.com/index.php?/topic/4393-ultimaker2-feeder-system-improvements-and-ideas/page-33 maybe have a look here, I did not published it jet (see also page 34) but maybe you could use my "compact" version of the well known low friction spool holder.

I made some progress, got inspiration from the "DIN rails" as used to mount breakers and stuff into electrical cabinets. So I designed a back plate, out of 3 parts to mount on the back of the UM2, which will give you 4 rails to mount stuff on. I like the idea of being able to move the spoolholder(s) from left to right, so if you change color while printing you can move the spool under the feeder. Will also be usefull when we get to dual feeder someday... or experiment with "paste struders" etc.... here's a pic of one of 3 parts (the right bottom part) , it has a left and right bottom part and a middle top part, mounted to the holes of the feeder motors, and a specially made bracket to fit into the originally spool holder holes, on top I will still need to make a clamb for the top part of the UM2 (or fix to 2 existing UM2 screws, not sure jet) Not shure if I'll be able to share and publish before I go on holiday in a few day's Obviously you could also use the components I made separately, It will be simple to make a holder for the "compact spool holder" to fit the "normal" UM2 location.

not sure if there are more versions of UM2, but on mine the coverplate's are held with 2 screws, one in the backpanel and one in the side panel..... about 40 cm from the bottom and 40 cm from the top of the cover...

Ha.. don't think i've ever seen that... my finger will heal... think i'll use a glove next time. Dont like the idea of screwdriver on glas....

Hmmm. Bad luck you guys talking about blood.... cut my finger open on the little clip holding the glass plate... these things are realy sharp... 1st time blood on my printer... try to make it also the last.

Looks very interesting. Would be nice if you could share a drawing on how the thing fits togheter ... exploded view ..

ahh thanks for the link, looking at daid's responce there's not much change ... anyhow as you say very low priority. made a mistake, have the nivigator not the pilot .. love it in DSM/Spaceclaim but did drastically reduce the speed of the mouse.

Any chance off getting my space pilot to work in cura ?

I did this , see page 28 .... also here I showed how I used a piece of string with some weight attached to keep the motor in place.

Have not seen Bas's test report yet, but like to share my "common sense" thoughts of the last week or so. I was triggered by the ideo of "3poro" (see page 31) to put the fillament spool on the side of the printer. My thinking is that these are factors that influence the friction of fillament in the tube (for sure not complete..); * bending of the tube, smaller curve - more friction * twisting of the spool v.s the head position * misallignment between the natural curvature of the fillament just off the spool v s the curvature in the tube * position of the "damaged side" of the fillament So I was thinking how to solve all this with a better position of spool and feeder. I think the spool should be more to the middle, to prevent tube bending as much as possible. I also think the spool should be placed in a way the fillament curve direction will not change in the tube So I created a test setup to play with; I don't have any real means to measure the impact this setup has on friction, but my gut feeling likes it Next idea: create a setup you can mount to the UM2, and have some modulare/flexible way of mounting spool and feeder - Back plate, to attach the stuff to (still to do) - mounting plates for feeder(s) - brackets for spool (ready) - spool holder (done) Roughly something like; The spool holder ("compact low friction spool holder"sounds good. ..) is derived from Roberts spool holder (the "core1" is unchanged") Would like to hear if you have good ideas on how to create modular mounting points on this back plate. Will probalby cutt it in the middle and use the original motor mount and spool mount holes to fix it to the UM2. Arjan

TOP !

Very interested... I'll buy one ...

SOLVED! this was a total waste of time flashed again, directly followed by a factory reset...... still same problem. then I had a brainwave.... what if I try to print something else .... problem solved! apparently the printfile was corrupt, maybe took the SD card out to fast or something ... still think it's odd to get this behaviour ...

Ok now I'm lost ... flashed the firmware again (from Cura 14.07) had no fillament in the machine, used the material change feature to load material, all ok. Then I go print (head still warm from material change, bed cold), print starts direct, feeder moving material all ok ecept for the fact that tyhe bed is still cold, so no adheasion to the bed. so; - firmware update did not help. - sensors ar ok - bed and head will heat from maintenace menu. I'm lost ... what do you think, would it be worthwile flashing back to older firmware ? I'm just thinking, after the firmware update I did not restore factory settings .. would I need to do that ??
