okay YouTube we just wanted to show you the 20 by 4 LCD display and my SD card is now working
but plug that in card inserted go over here SD card and you get your SD card content so
that's working so I showed you how to set that up in the previous video and then let's take
a look at the printer I just finished printing one of my battery holders and I think this one
worked out much better so I I tried printing one yesterday and I don't know if you can see
that but the the bottom lifted up and part kind of warped on me a little bit don't print PLA all that
much I mainly use ABS and I run with ABS around the bed at 90 degrees C the last time I printed
PLA was this summer and it was hot up here in the attic probably over a hundred Fahrenheit which is
about forty degrees C and I was printing many of these with no bed heat and I was having no problem
and then I did the same thing yesterday and you can see how warped that is you can definitely
see there's some distortion in the part and I printed that yesterday with no bed heat and I
had the warping problem so what I decided to do was run the bed at about 40 degrees C and I got
perfect adhesion no warping at all and I think it's just cold enough up here in the attic it's
about 50 Fahrenheit so I think having a slightly warmer bed is maybe the trick so this was done
with the six by six by linear bed leveling and then they the three by three subdivision which
results in 15 by 15 mesh and you can see the parts stuck down the whole bed I can lift it off of here
yeah there we go print it out really nice there you can catch the site the other thing I've done
to improve the exterior print quality as I drop the temperature from 220 down to 210 so that
seemed to really help here and then I've also dropped the extrusion multiplier a little bit
and I get a lot nicer smoother outside finish I tried a 200 but I had problems with the material
not sticking these first layers were just not at hearings looks like 2 10 and 40 degrees C
on the bed is the sweet spot for PLA you can see here here's the flex plate so I'm just going to
give it a bend like that yeah there we go you can just hear it pop loose right there and there's my
parts came right up just a perfectly flat bottom really nice and so that's that parts ready to
go and then the outline here pretty much comes up in one piece and then what I do is the last
part I printed this way so I just rotate my bed 90 degrees get my magic eraser here just erase
all the until you can't see the old lines that's just a green scotch-brite payout I hit them with
a little bit of 70% isopropyl wipe it down and I'm ready to go for tomorrow this bill tack is getting
a little bit beat up I think I'm getting towards the end of it I've got a couple a couple of tears
in it like right I think right there I've got one and there's a couple of places where it's starting
to go but I figure I'm gonna try to get as many prints out of it as I can anyway I thought I'd
show you that update I'll put some of the other videos over here on the left side and if you have
