== Glass Print Plate Usage ==
Glass plate is of GO-3D brand, hopefully real mccoy stuff that is flat... It is covered with a PEI sheet that is adhered to the plate with 3M 468MP High Temp Tape. A blue silicone heat transfer sheet keeps the glass in place with friction and fills gaps between the plate and the aluminum bed, it is a type of silicone used for heat sinks for electronics.
 
* NEVER CLAMP glass plate to bed. It will cause warping of the glass plate. Yes glass warps and bends, look it up. The silicone sheet will keep it in place no problem.
*One corner of the print plate is marked 'Front Right' and is blacked in a little around the corner. When facing the printer, this corner goes to corner that is on the right-hand side and is closest to you (duh, but just to be sure...).
*The temperature of the surface of the glass plate will be lower than the aluminum bed, may have to use higher bed temp than on other printers
* PEI sheet is prep-free surface for ABS and PLA, hot or cold. If you have another material, check first to make sure it will work on PEI. If not, then put tape on top of the sheet and then glue/hairspray/whatever.
* Clean PEI sheet with 85% Isopropyl Alcohol and a paper towel, a green spray bottle should be near the printer. Can also use soap and water.
* The flat spatula used to remove objects from the print plate is also useful for removing glass plate from silicone sheet.

== SD Card ==
You can print from the printer directly by putting your print file on an SD card, there is one already in the printer. It only accepts x3g files, so you will have to convert your .gcode file (made in slic3r) to x3g using this utility http://markwal.github.io/GpxUi/

A copy of GpxUi can be found on the SD card in the printer.

==Lokbuild Print Surface==
*Can use heated bed for PLA, but with the bed off it will adhere to the surface no problem.
*Can use heated bed for ABS, use whatever temperature you normally would
*for other materials see official site http://www.lokbuild.com/ or search it on internetz
**according to them, it can be used with: ABS, PLA, HIPS, PET, colorFabb_XT, colorFabb nGen, colorFabb_HT, colorFabb XT-CF20 (carbon fibre), Woodfill, Bronzefill, Copperfill, Brassfill, Polymaker PC-Plus (polycarbonate), Polymaker PC-Max (polycarbonate), Polymaker PolyFlex, Ninjaflex
*Lokbuild is durable. Rana has printed 100's of times on it at home and it still is good as new.
-----
Usage:
*Use Lokbuild surface alone. Do not use tape, or "ABS Juice", or glue stick or anything
*Print as you normally would. Rana finds even large prints do not curl, but use a brim or raft if you like. No fan for first layer.
*To remove print, use the flat spatula to get underneath as usual. A room temperature print will just pop off easily. Lokbuild is durable, but if you really try you can scuff the surface.
*MUST ALLOW heated bed to cool to room temp before you remove print. Not doing so may remove the Lokbuild surface. If you're in a hurry put a fan on it.
*You may see markings on the surface from where your print was. This is not a problem, you can print right on top of the markings as usual, they do not affect adherence of plastic to surface (at least for PLA... rana hasn't tried other materials)
*Praise Lokbuild god that you don't have to use tape anymore. Lokbuild will cease to adhere if ritual offerings are withheld.
-----
Cleaning:
*use warm-hot water with dish detergent, scrub with the green side of the sponge. Rinse with water. This should remove any markings left over from prints. The surface should look good as new.
*May also clean with <10% isopropyl alcohol.
*DO NOT put acetone on surface or high % isopropyl, this is will damage the surface.
-----
Print not sticking? Raise the bed up a little to squish that first layer more. Or use a heated bed for the first layer. Like 50-60 C for PLA?
-----
If your material is not compatible with lokbuild, put tape on top of it, then put hairspray or glue stick or whatever.

==Print Settings==
==A few random printing tips==


These are general printer settings that work. If filament has different temperature settings, follow filament temperature settings.
*Smaller prints will better adhere to the bed than larger prints. If the print hasn't failed in the first 10% of the print job, it will be unlikely to fail after that.

*Use Cubic Infill (Available only in Slic3r prusa edition), as it provides rigidity in all directions [http://www.prusaprinters.org/introducing-slic3r-prusa-edition/] and doesn't make printer resonate.

*Do not use honeycomb -- as at the speeds of the default settings, it will cause printer to resonate and skip.


Do not use honeycomb -- as at the speeds of the default settings, it will cause printer to resonate and skip.
*Leaning or drifting prints? Tighten all the belts, especially the Y-axis stepper motor belt. That stepper is prone to becoming loose because the Y-stepper motor puts out more power than the X. A link to a video is in the maintenance section.


------
*Always store the printer with the X carriage in a corner. (It homes itself to the back left corner anyway when a print is done). But this is to prevent the X and Y axis rods from sagging over time, especially the X axis. It's a known problem, I think, I swear I read it on the internet!
'''Orange (translucent) PLA:'''
 
 
In Slic3r in Fillament Settings tab, '''Right Extruder''' filament profile and in Print Settings tab, '''Fast''' print profile.
 
First Layer:
  Filament: 220
  Bed:      70
 
 
Other Layers:
  Filament: 210
  Bed:      60

Print using *105% flow*
------
 
 
'''ABS:'''
 
In Slic3r in Fillament Settings tab, '''ABS Right''' filament profile and in Print Settings tab, '''ABS_first_layer''' print profile. Currently profile is set to 6 skirt layers -- this is normal, ABS needs wide skirt for better adhesion to the bed.
 
 
When printing, you '''absolutely have to''' have a heated chamber, or ABS prints will definitely warp and very likely will not stick to kapton tape.
 
In order to construct heated chamber -- cover the front of printer with a piece of plywood or MDF from the workshop and put some cardboard on top of the printer out of extruder path so the heat escapes more slowly. Pre-heating heaated bed for 5 minutes before starting helps a lot -- set the Bed temperature to 100C in Octopi temperature tab.
 
------
ABS Juice: help with sticking to the bed (especially for large prints)
*when bed is cool, wipe the kapton tape clean with acetone (I used a paper towel with acetone on it)
*take a clean paper towel, put acetone on it and wipe a piece of the ABS with it to get some 'ABS juice' on the towel. Then wipe this over the bed. There should be some failed prints in the 3D printer, or check the mini-can beside the 3D printer for failed prints
*allow to dry completely (~5 minutes), you should see streaks of ABS on the bed. Heat up bed and print as usual.
*ABS should now stick well. Remember to block the build volume to stop air drafts.
------
 
It's better to start ABS prints towards the back of the printer where ambient temperature is more stable. To disable auto-centering, in Slic3r Prusa Edition go to File --> Preferences then uncheck 'Auto-center Parts'.
 
First Layer:
    Fillament: 240
    Bed:      100
    Bed for large prints: 120, use ABS juice!! (See above)   
 
 
Other Layers:
    Fillament: 235
    Bed:      95
    Bed for large prints: 110

| Y-axis appeared to be skipping steps, but we found that there was a set screw loose on the timing pulley on one of the sides, so the whole gantry was driven by the belt on one side only. We tightened the set screw and squared the axis. Also, we flipped the timing belt pulley (hub toward the motor) on the Y axis motor so that the belt doesn't touch the motor flange. It's harder to access but it's tightened well and hopefully you won't have to tighten it again. We also retightened all the other belts for good measure. It works well now.

| The feeding tube for the filament is too wide (4 mm ID 6 mm OD) and too stiff as a result. The problem is, it pushes on the print head in one direction so when the axis is loose, it is printing skewed towers of pisa, in the direction in which the tube pushes. We fed the wire without the tube so that there is no extra pressure on the axis. Therefore the printing errors average to zero.
We bought a smaller and less springy tube (also PTFE) but we are waiting for someone more knowledgeable to install it.

| Loosened the Y-axis short belt, lol. In my zeal I tightened it too much, I guess... (the prints were still drifting back a little, the vertical lines were wobbly...) The belt is good now I think, it should make a low sound when you strum the belt. Also changed the screws holding the Y-stepper, added washer and a rubber ring to keep it in place.

| The aluminum print bed is warped (bowed, with middle as the high point). After trying to level it five million times, finally hit the printer with a baseball bat and it fixed it. Just kidding. Bought a GO 3D glass plate for the bed and a silicone heat transfer mat that keeps it in place.
