Rostock MAX 3-D Printer

Basic Info

  • Ownership: Andrew Meyer (100%)
  • Location: South wall, you can't miss it.
  • What it looks like:
Rostock MAX

Manufacturer Information

  • Make/Model: SeeMeCNC Rostock MAX
  • Part Number: N/A

Documentation

SeeMeCNC homepage

Rules

  • Please get training before use.
  • 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.
On the left, hot-melt glue stick. On the right, Elmer's School glue stick. Do NOT use hot-melt glue sticks on the print bed.

Instructions

Normal Printing

  • 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
  • Put the SD card back into the Rostock and print your file
  • 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 6 binder clips that hold it to the heater. Two sit in the front, then one per gap in the heater support around the perimeter. Positioning of the bed is not critical.
  • If the bed looks like it have patchy areas of shiny glass, use a standard Elmer's School glue stick (not a hot-melt glue stick!) to recoat those areas for the next person.
  • 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.

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 Andrew 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 Matt Gardeski (preferably via 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 the window cleaner next to the printer and a towel. PET sticks to shiny clean glass and comes off cleanly when the bed is cooled

Maintenance

Daily

  • Ensure even coat of gluestick on bed.
  • Get hotend up to temperature and wipe off encrusted plastic with a shop towel, if any.

Weekly

  • Wash off glass plate for heated bed. Regular soap and water will do. Recoat evenly with gluestick after cleaning.
  • 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.
  • PTFE/Teflon spray lube into all delta joints--thoroughly wash bed with acetone, isopropyl, and soap and water afterwards, then recoat with gluestick.

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.

Firmware

5-24-2014 - Firmware was updated to 0.91 from: https://github.com/seemecnc/Repetier-091-ROSTOCKMAX.git K-Type Thermocouple and AD595 Thermocouple amplifier was added. This requires configuration changes in the firmware. If you update the firmware in the future be sure to make the changes below:

  • Configuration.h

#define EXT0_TEMPSENSOR_TYPE 100

  • Pins.h - under board config "RAMBo Pin Assignments"

#define TEMP_0_PIN 8

Things that Need to be Done

  • Automated display of per-print cost.
  • Cooling fan design/build.
