I'm wishing I could go back in time and had waited for the UMO+ (or UM2) !

You already have a bed kit, buy a um2 china board and drill some holes on the woodframe and done. Umo+

I use one. I have another on a bag for a rainy day.

Ofc the china board takes 3secs more to bootup, it has a weird 3C difference no matter what pt100 I plug, but ofc cheap, is cheap.

I know Fabrc8 will want big $ for a real board...and then there's the matter of upgrading the print head...or just upgrade to the UM2+ Extruder upgrade. Figure in $399 for the board, $399 for the extruder upgrade...and well, that's probably money better spent on another UM2+

Extruder upgrade.... you can keep the umo feeder men, is more powerful than the um2+

And important parts to change on hotend, heater 35W, tfm coupler, metal spacer. 60$ tops.

That's what I did to my UM2 head on my UMO+ so far. Not sure on the total but around the sum Neotko mentioned.

I don't like the handling of the stock feeder though but it works fine. So it will stay there until the ZGE is ready :)

I finally fixed the metal shield for the fan shroud by gudo so now I have better fans on my UM2 head :)

Running a test print now with the "crappy" reel of Ultimaker filament to see how the fan shroud works and holds together. Fan speed set to 50%.

Once I know it works fine I will make a small modification to the hinges and then print a new version.

Got everything dialed in pretty good for printing PLA @0.1 mm with Gudo's fan shroud. Fan speed is down to 30% now. For 0.2 and up I haven't tried so much but I think it will be enough to up the temperature a bit.

These photos are from a print with Polymaker Polymax.

Printed a 3Dbenchy with Colorfabb XT to see if the suggested settings were ok before starting to print all the parts for the F1 steering wheel :)

So 0.2 mm @245C/70C, 50 mm/s...turned out pretty good. Fan settings same as for PLA.

Bridging looked good also (part for the steering wheel):

Wow, you did that with XT? That's a notoriously difficult filament to dial in correctly

Yes, its XT.

All I did was read the recommendations on Colorfabb's homepage and tried that :)

The big parts for the steering wheel has some slight warping issues. So that's the one area that I need to improve right now...but for these parts it doesn't really matter. It's a good project to experiment with XT and learn how to use it :)

Tried diluted wood glue and set the bed temp to 74C and all the XT parts I have printed since then have been 100% flat :)

Also for XT you need Amedee firmware with PID control or the Tinkergnome firmware with PID. UM can't offer PID on UMO/UMO+/UM2 due EU electrical noise emissions. No PID, no good adhesion, for almost any complex material due changes of temperature

Already loaded and enabled :)

But, imo, the glue stick that came with the printer is not the best. Wood glue is way superior so far.
