@neotko, he does not have a UMO+ Just a UMO like me The question is about re-using the UM2 head in the UMO The article you linked refers to using a UM2+ on a UMO+

Hi Christian, If you haven't touched the UMO in a few years, I would start out with some sewing machine oil and lightly lubricate the rods. I left my printer idle for a few months and when I went to use it again, it was a noisy awakening! A little goes a long way. After doing that, move the print head around and it should move freely. There's a lot of sources for hacks and tweaks. Thingiverse and Youmagine is full of them but seldom is there much discussion about what's worked and hasn't. If you are looking for some specific UMO tweaks and some conversation about them, read here. I don't know a lot about the eBay type heated beds, I went with the official one through Ultimaker last year. It took a bit of a learning curve to use it right and it really makes a huge difference. You can use a lot more materials and kiss blue tape goodbye.

@neotko has a nice document for a UMO upgrade using the UM2 head I've thought about re-using the UM2 head since I upgraded to UM2+ I have an Ultimaker Original but there's some question about how to make the existing electronics work (sounds hard) or replace the UMO with UM2 main board (again, pricey). Also, I know I was looking around at replacing the guts of the UM2 print head with the latest stuff (spacer, teflon, etc)

Can someone from Ultimaker check into this? It's annoying to have to keep importing it from SD card. If I power the printer off, then on...my additions are not there. @sandervg ?

No no no no.....I dropped one of the alignment pieces and it broke when it hit the floor. (I then had to rescue it from a kitten who thought it was a new toy)

0.40 printing at 230C

I think it is using ZigZag, which seems to be the default in Cura

Good illustrations I was beginning to think I should try a different support type I think others that print this part up use S3D and "Helper Disks"

Maybe @tinkergnome or @nallath can chime in

That's a win for the kids!

That's a great deal....now if I could only get that money tree to bloom...

Any tips on these "hairs" on my nGen print? I know they are easy to remove, post processing with a heat gun or the like. But while printing, they tend to hit the nozzle and gunk it up

12 hours later...printer reports 2 hours left to go. (Wish I knew why the printer gives such crazy numbers this time around) Brim seems to be holding it down well. I know some like brim, some do not. But for a print this sized and at this orientation, it might be what works.

Well another issue I noticed is despite saving the values, if you power the machine off and on....the materials you added on not there. I have followed the instructions and something seems to be missing. I had to re-upload the data again.

Well let me show you how the print is progressing...bed leveling looks fine to me?

...and now 48....what's with Cura's time prediction

Okay, using those settings. Looks like my 15 hour print went to 24!

Thank you @tinkergnome Should I change the support pattern?

Worth a try....air gap?

A few thoughts in review... I've been doing some research, since this is failing on multiple filaments... Maybe I just got lucky on the first two prints that worked. The rest have all failed. zhop helped with the rumbling but I think it boils down to the print is coming off the bed. Should I be adding brim? The entire base of the print is support material. How much? Distance? Line count? There's a lot of posts about the first layer being hotter than the rest. I don't see a really good way to control this in Cura 2.3.0 It looks like manually upping your print temp through the printer interface might work best. This print uses all support material on the bottom, so something is going on down there causing the adhesion to fail.

I'm glad I found this.

Well this failed again. I suspect a problem with the heated bed...I mean, what else could it be??? I'll process the time lapse...

I'm going to try @neotko 's idea. It sure makes for a lot noisier printing experience Maybe this will help Here's the settings I used...

Well it happened again It shouldn't be knocking the support material down! Especially nGen! I mean, between gluestick and 85C, that's quite a bit of force to break that off. Could Coasting be doing this? I wanted you to see how the print goes and you see how at some point it knocks the support material around (see 35 second in)
