Ha yeah i reckon the next mod is to turn the bed heat down …this white bit a the front of the bearing was a bit tougher to remove …i blame the bed. Still leaps and bounds to what the non modded extruder was like. _________________ Miles Blow - Julie Pitts

I wouldn't turn the bed temp down, 50c is already fairly low. I'd just maybe change your nozzle height a bit, and maybe tweak the bed a little to be slightly more level (seriously I just do this by hand most of the time).
Also fan door open for aftermarket filament usually helps, I often pop it open after the first layer has gone down. _________________ ( •_•)
I have no idea how you tweak the bed with out it all going to hell. Everytime I try to tweak mine left, it jumps a belt and I have to reinitialise it all again and calibrate the bed height... This is the only thing shitting me off about my printer right now _________________ https://www.halfdonethings.com/

How badly out is yours aaron? And is it only out left / right? you can adjust front / back easy enough with the little spring loaded screw at the front.
There's a few other ways to correct left / right problems, including tweaking the guide rails to push more on the perfboard on one side than the other. _________________ ( •_•)
Right now it's out a lot in the front right of the bed. I run out of software adjustment (1mm) and the head ends up hammering the perf board in the back left corner when I adjust the head height lower enough for the print to work correctly in the front right....

Anyone tried printing not a smooth surface rather than the holed plastic on the mini up? Im thinking it would be good for raft less printing. _________________ Miles Blow - Julie Pitts

I've been having some bad ass success with the new TPU filament from 3D Printer Gear - basically same stuff those weldable belts are but as a 3D Printing Filament..
You have to do some pretty serious mods to the machine, mostly keeping the stepper cool or it starts chewing the filament - and a 11ohm resistor works well with ABS settings, fine speed, raftless with 250micron layer heights.
Sadly it's a firmer mix of TPU so it's not grippy enough for belts... but damn it could be used for all manner of flexible, tough parts! I'm thinking as a better solution for motor mounts, with a bit of flex for shock absorption.
This is very cool. Itd be great if there was a mod kit available to suit my printer to go with it _________________ <Patrician|Away> what does your robot do, sam

Hehe I'm sure there would be a market! Sadly I think the UP Mini just gets too hot to print these kinds of materials (including PLA). Stick with ABS, if you want anything rubber printed shoot me the file! _________________ ( •_•)
