Hahaha I couldnt resist any longer. I wasnt going to post these but figured what the hay... I explain more of what your looking at on my site. Just some temporary cooling devices in place. They're not pretty... but they're pretty awesomeby banthafodder7400 - General
I was having a problem with a different axis and this is what I was told. It worked for me. Quoteakhult 1. grab a small flathead screwdriver (tiny) 2. turn all your trimpots down (counterclockwise), don't accidentally touch the board - you could fry something! 2. send pronterface a long move command for the axis you're adjusting 3. slowly turn up the trimpot until the stepper starts to move.

on my gen 6 electronics there are 4 trimpots, 1 for each motor (X,Y,Z, and extruder) directly above the plugin for that motor (or below depending on how its oriented). They are can be turned with a small screwdriver. Clockwise turns up the current. The only thing is the more current your send the warmer the motors get. At least in my observation. Just becareful not to touch anything else on the bby banthafodder7400 - Printing
Do you have a picture of what your circles look like? I tried printing some simple 15mm cylinders to stest my circles and I might be having a similar issue. The sides are alightly wavy. On straight prints my Prusa is doing very wellby banthafodder7400 - Printing
i use a replacement 8x10 picture frame glass I got at the homedepot for 1.98by banthafodder7400 - General
So after some playing around, i discovered my z height was definitely an issue. I couldnt even slide a piece of paper under the nozzle in home position. I upped it to around .01" and its sticking (80% of the time) Will try ABS juice sometime, but definitely can say this problem is pretty much solved! Other issues I have I will save for other topics. Thanks for the help!by banthafodder7400 - General

.35 or .4 I think, I dont rememeber what I set it to. I will have to check it when I get home later . Either tonight or tomorrow morning.by banthafodder7400 - General
Im leveling it by going to the corners of the print area and putting a gage block between the nozzle and the glass (I have access to gage blocks from 0.100" to 7.000" in .0001" increments). So I set the z height at one corner so that the gage block just slides under it. Go to the next corner and do not touch the z but adjust the bed until the same condition, then I check a few other locations. Itby banthafodder7400 - General
If I understand correctly... My heatbed is raised off the acrylic by little nylon spacers, and I have glass directly ontop of the heatbed... So there is a gap directly under the red heatbed. You are saying to add some kind of insulation below the heatbed, so between the board and the acrylic right? Or is your duct wrap between the glass and the heatbed? I think your saying under the bed, just claby banthafodder7400 - General
Thanks for the help Akhlut! It fixed my print from shifting. Now Im back to my original problem of prints not sticking. If you look at my post for 4/5 on my site you will see that my print quality has improved significantly. The problem? The bottom of my parts are terrible. The first layer doesnt stick, and sometimes doesnt even extrude the right amount. Once the first layer is competed I useby banthafodder7400 - General

I think its pretty tight, my trimpots are at what they sent to me as... horizontal (parallel to long sides of board). Should they be adjusted?by banthafodder7400 - General
The glass did work with when doing a 20mm cube. With the 20mm cube my layers shift a few times towards y-home. Not sure why, the axis is nice and tight and doesnt slip during the print. I dropped to a 15mm cube to save on material while working on the shifting problem but that doesnt stick. Is it too small to bond well to the glass? should I have a fan cooling it as it prints?

Pretty neat idea, Ive often thought about it. I just got started with building my afirst printer so something like this is a ways down the road. I will be watching to see how this turns out for youby banthafodder7400 - General
Much better than the price I used on my senior design project at college! It was a laser scanner system to measure thread pitch and form of a die that cuts threads into bolts. Only about 12K for the system But these were the bearings we usedby banthafodder7400 - General
Well I bought a piece of replacement glass for an 8x10 photo frame at the home depot for 1.98... clamped it to the heat bed and it worked like a charm. Now my issue is the layers shifted twice during the build. I have a feeling I know what it is, but I didnt pay attention to which direction they shifted! I will troubleshoot this tomorrow to see if my hunch is right Thanks for the help! Alsoby banthafodder7400 - General

So I finally got my Prusa2 printing last night. Kinda... I am printing on a heatbed (unknown temp) with a layer of blue painters tape, Hotend about 230, ABS. I am just printing a 20mm cube to make sure that everything is working fine. The corners arent sticking well to the bed, so part of the way up the print you see them pulling up and beng pushed down when the nozzle goes over. Half way up (9-1by banthafodder7400 - General

I had this problem yesterday! I fixed it though, let me check my code when I get home today. I think I know the problem though.by banthafodder7400 - General
Got it!!! the problem was really kinda stupid.... I tried using my wifes laptop instead of my computer and It wasnt working either... so I figure... lets turn the power supply on! haha I was told I didnt have to have it on to do the driver stuff since it would get enough power from the usb port for the chips to work(not for the motors to work though)... well once i turned it on the computer pickeby banthafodder7400 - General

nope, thats what I had been trying... I tried again, right clicked, uninstalled, downloaded file, opened "CDM20814_setup" and shows the little black dos screen, says it completes.... i open device manager and it shows the same USB wish no driver... ive tried various ports on the computer all the same.. i tried right clicking and saying run as admin... no change.by banthafodder7400 - General
I have been trying for hours to get my gen six to be recognized by the computer. When I open device manager I get the yellow exclamation point thingy on one usb drive, it is showing that even after i have unplugged the board. When I try to install the driver it appears to go but then nothing happens.
