Intro:
Rules:	*Please donate $0.10 per cubic centimeter or per gram of ABS (or $0.20 per cubic centimeter or per gram of PETT), whether or not the print succeeded. This covers both replacement cost of media, and maintenance costs. There will eventually be an indicator on the LCD at the end of the job, or when the job is terminated, showing an estimated cost of print.
Instructions:	=== Normal Printing === ==== On convenient computer... ==== Get your model into an STL file. Run CURA from the icon on the desktop of the Rostock VM. It will open with the settings left by the previous user. File->Clear platform File->Load model file Check that infill, perimeters, etc. are set the way you want. At the top of the CURA window, there is a readout of how much filament will be consumed, both in linear meters and in cubic centimeters. Since ABS has a density roughly equal to 1 gm/cm^3, you can assume that your print will be roughly this much plastic in grams. Plan payment accordingly. File->Save gcode (it has already been generated while you weren't looking) Copy the gcode file you just saved to the Rostock SD card ==== On the printer itself... ==== Note, the power switch is around the right back side under the bed, next to where the power cable goes in Put the SD card back into the Rostock Print your file; this should happen as soon a you power on the printer - once the card is in place and read Note that the fan on the moving platform will turn on and off automatically; you do not have to do anything special to make sure it does. Wait impatiently for your print to finish. Wait some more. And a little more. Once the print is done, wait for the bed to reach ~40C, and forcefully pry the print off the bed with your hands. '''DO NOT USE A METAL SCRAPER--THE BED IS GLASS.''' If the glass comes off, there are 3 binder clips that hold it to the heater. One sits in the front, then one to each of the back edges, roughly 120° away from the front. '''Positioning of the bed is critical; please align the two black arrows in the front of the bed.''' '''DO NOT USE GLUE ON THE BED''' Toss the recommended donation based on the final mass of your print (based on the scale, not the CURA readout) into the bin labeled for the purpose. === KISSlicer Settings === Get working [http://kisslicer.com/ KISSlicer] [http://i3detroit.org/wi/index.php?title=File:KISSlicer_settings.zip config files here] === Cura Settings === These are my current settings for v15.04.4. I've had good success with these settings and ABS. I will update this section with any future improvements. Any settings that aren't specifically mentioned, leave as default. Below is a pic of a recent print. -[[User:Truefreak\|True Freak (Alec)]] [[File:Truefreak-XWingTokenHolder-SecondPrint.png\|150px]] Machine Settings * Maximum width and depth: 280mm Maximum height: 360mm Extruder Count: 1 Heated Bed: Yes Machine Center 0,0: Yes Build Area Shape: Circular GCode Flavor: RepRap (Marlin/Sprinter) ** All other settings: 0 Basic Settings * Quality * Layer Height: 0.2mm * Shell Thickness: 1.4mm * Enable Retraction: Yes Retraction Expert Config * Minimum Travel: 1.5mm * Enable Combing: No Skin * Minimal Extrusion Before Retracting: 0.02mm * Z Hop When Retracting: 0.075mm Fill * Bottom/Top thickness: 1.4mm * Fill Density: 20% ** Fill Expert Config * Solid Infill Top: Yes * Solid Infill Bottom: Yes * Infill Overlap: 15% * Infill Prints After Perimeters: Yes Speed And Temperature * Print Speed: 30mm/s * Printing Temperature: 250c * Bed Temperature: 80c Support * Support Type: None * Platform Adhesion Type: None ** Platform Adhesion Expert Config * Line Count: 2 * Start Distance: 1.5mm * Minimal Length: 150mm Filament * Diameter: 1.75mm * Flow: 100% Machine * Nozzle Size: 0.7mm * Advanced Settings Retraction * Speed: 40mm/s * Distance: 4.5mm Quality * Initial Layer Thickness: 0.3mm * Initial Layer Line Width: 100% * Cut Off Object Bottom: 0.0mm * Dual Extrusion Overlap: 0.15mm Speed * Travel Speed: 100.0mm/s * Bottom Layer Speed: 15mm/s * Infill Speed: 0.0mm/s * Top/Bottom Speed: 0.0mm/s * Outer Shell Speed: 0.0mm/s * Inner Shell Speed: 0.0mm/s Cool * Minimal Layer Time: 5sec * Enable Cooling Fan: Yes === Error Recovery === If anything goes wrong with the print, turn off the machine with its power switch. Please '''do''' contribute to the filament fund for the mass you did end up with. Take notes (and pictures!) on what failed, and send them to {{Pretty Link\|Amelia Meyer}}. === Filament Change === If you want to change the filament that is in the machine, set the Extruder temperature to 230C through the machine's LCD interface, and wait for it to heat up. Hold the red lever on the extruder down, and firmly pull up on the filament, drawing it up and out of the hotend and Bowden cable. Neatly spool up the filament back onto its source spool, lock the end into the spool side, and grab the new spool. Feed the filament through the top plate of the machine, and into the extruder--make sure to hold down the red lever on the extruder. Once you have the filament in the Bowden cable, keep pushing the filament through until you see filament of the new color extruded out of the hotend. Go print! === Printing with PET filament === Polyethylene terephthalate is an experimental material for this printer hand has some know issues. That being said, it makes very pretty things if you're careful. Contact {{Pretty Link \| Matt Gardeski}} (preferably via [[Communication#IRC]]) because he bought the stuff and spent many hours working with it. In your slicer settings, set bed temp to 65C. This is the lowest temperature at which the PET will stick to the glass and is cool enough that the PET will harden reasonably quickly. Set nozzle temperature to 212C. This is important. PET is more sensitive to temperature swings than ABS. Set fan speed to 100%. If you don't, the filament will buckle inside the hotend and someone will have to disassemble it to get it out. The 0.7mm nozzle tends to produce better results with PET. It's the one without all the burnt ABS crud on it. ''Clean the glass.'' Use isopropyl alcohol and a towel. PET sticks to shiny clean glass and comes off cleanly when the bed is cooled === Reasonable temperatures === ABS: hotend 210-240, bed 80-100 * PLA: hotend 190-210 * "T-Glase" PETT: hotend 212-224 If in doubt, check http://seemecnc.com/.
Maintenance Info:	=== Daily === '''DO NOT USE GLUE ON THE BED''' Get hotend up to temperature and wipe off encrusted plastic with a shop towel, if any. === Weekly === Wash off heated bed. Isopropyl alcohol '''ONLY'''. '''DO NOT USE GLUE ON THE BED''' Ensure axes run smoothly, and no damage to belts is happening (no black rubber dust under the three axis motors). === Monthly === Run PID autotune on bed and hotend. Ensure bed is level and calibrated. [https://seemecnc.dozuki.com/Guide/Calibrating+Your+Printer/51 Rough calibration], [https://www.seemecnc.com/pages/delta-calibration-wizard Fine calibration] PTFE/Teflon spray lube into all delta joints--thoroughly wash bed with isopropyl alcohol, and soap and water afterwards. '''DO NOT USE GLUE ON THE BED''' === Restocking === The filament is nominally 1.75mm diameter plastic filament purchased from SeeMeCNC. Please '''do not''' source filament from anywhere other than SeeMeCNC without asking first--many cheap suppliers pad out their filament weights with tiny steel ball bearings, which will cause havoc in the hotend. == Filament Stock == # [http://seemecnc.com/collections/filament/products/1-75mm-neon-green-abs-2-spool SeeMeCNC Neon Green ABS], 1kg, purchased 2013-07-27 # [http://seemecnc.com/collections/filament/products/1-75mm-neon-orange-abs-2-spool SeeMeCNC Neon Orange ABS], 1kg, purchased 2013-07-27 # [http://seemecnc.com/collections/filament/products/1-75mm-dark-blue-abs-2-spool SeeMeCNC Dark Blue ABS], 1kg, purchased 2013-07-27 # [http://seemecnc.com/products/1-75mm-t-glase-1-spool Taulman T-Glase PET (AKA PETT, AKA PETP...)], 1lb., purchased 2013-10-01 # [http://www.dcplastico.com/shop/abs-175mm-filament?category=Filament DC Plastico Black ABS], 1 kg, purchased 2014-10-04 # [http://www.dcplastico.com/shop/pla-175mm-filament?category=Filament DC Plastico Transparent blue PLA], 1 kg, purchased 2014-10-04 # [http://www.dcplastico.com/shop/pla-175mm-filament?category=Filament DC Plastico Transparent green PLA], 1 kg, purchased 2014-10-04 # [http://seemecnc.com/collections/filament/products/1-75-mm-white-abs-filament-2-spool SeeMeCNC White ABS], 1kg, purchased 2015-02-20 # [http://seemecnc.com/collections/filament/products/1-75mm-grape-abs-2-spool SeeMeCNC Purple ABS], 1kg, purchased 2015-02-20 # [http://seemecnc.com/products/1-75mm-bridge-filament-1-spool Taulman BRIDGE Nylon], 1lb., purchased 2015-02-20 == Setup and Mechanical Alignment == <s>[http://download.seemecnc.com/rostockmax/Rostock-MAX-Assembly-Guide.pdf Rostock-MAX-Assembly-Guide.pdf]</s> <s>[http://download.seemecnc.com/rostockmax/Rostock-MAX-v2-Assembly-Guide-3rdEdition.pdf Rostock-MAX-Assembly-Guide.pdf]</s> == Firmware == Firmware loosely based on 0.92.2 from [https://github.com/seemecnc/Firmware].
