MakerGear M2 - Basic use

Confirm PLA filament is loaded in the printer. Because two rolls can be mounted on top of the printer it is important to confirm which roll is currently fed into the extruder. See green arrow in the image. You should also note the manufacturer of the filament. In the example here, Overture PLA is loaded.

Confirm there are no prior prints, debris, or filament residue on the print bed.

If there is a completed print on the print surface you are welcome to carefully remove the print and set it aside. Remove the magnetic surface from the printer, flex it to remove the part, and then return the bed to the printer. Be sure to line up the surface so that it is aligned with the heated bed and not askew. See example image.

If you need to remove filament from the print bed you may use one of the plastic scrapers. Be sure to remove the print bed from the printer before you use the scraper. NEVER USE METAL TOOLS ON THE PRINT BED OR YOU WILL DAMAGE THE BED!

You should also remove any existing makerspace cards or Proxy cards from the the Portal box. Press the green button and then wait for the box to return to blue before you proceed.

Locate the SD card on the right side of the printer interface. Remove the card from the printer.

Locate an SD/USB adapter. There are several on the sides of the enclosed 3D printers.

Insert the SD card into the adapter and then plug the adapter into a USB port of the computer where you used PrusaSlicer. Make sure the SD card logo is facing up as shown in the image here.

Reinsert the SD card into the printer interface (the SD card label should face away from you). Your print file should appear at the top of a list of files. If not you may need to scroll through a list of files. Locate your file by name, rotate the knob to highlight your file, then press the knob to select your file.

A confirmation screen will ask you to confirm you wish to print the chosen file. Rotate the knob and press to select the Print option.

The display should now show some printer stats and the message, "Bed heating..." should appear at the bottom.

The printer will now warm the print bed and move the bed to the top of the printer, then heat the nozzle. Once these steps are complete your print will begin.

3D prints fail most frequently during the printing of the first layer. You should always stay and watch the first layer of your print. Look for the following:

Is extrusion of filament inconsistent? Is it wider or more narrow in some places than others?

Does the first layer appear wavy, bumpy, or uneven?

Is there any curling?

Is there any filament that did not adhere to the bed?

If you answered YES to any of the above questions, please pause the print and get a tech!

Sometimes the printer screen will display strange characters. It is safe to ignore these messages and characters. They will not affect your print.

To clear the screen press the knob, highlight Info Screen in the next menu, and press the knob again.

This will return the printer to the normal printing status screen.

When your print is complete the printer will move the bed down and move the print head out of the way. You should carefully lift a corner of the metallic print surface to completely detach it from the magnetic bed.

Never remove parts while the print surface is still attached to the printer. This can throw off calibration, causes errors with bed leveling, or otherwise damage the printer.

Once you've removed the print surface you can flex it (don't be afraid to apply a good deal of pressure/flex) to detach your print from the surface.

If your part will not release, or filament is left stuck on the print surface, please use one of the orange and blue PLASTIC scrapers to remove filament from the print sheet.

NEVER USE METALLIC TOOLS ON THE PRINT SURFACE! METAL TOOLS WILL DAMAGE THE PRINT SURFACE.

Make sure the print surface is completely clean before returning it to the print bed.

Once you have removed your print and all remaining filament from the print surface you should return the print surface to the printer.

Confirm you have the print surface oriented as shown in the photos here.

In addition to the print surface aligning with the bed you should also confirm that the bed is sitting flat/flush inside of the carrier. The bed should not be lifted out of any of the four corners of the carrier. See the photos here for examples.

If your part had support material you should be able to remove it using your fingers. Sometimes a pair of needlenose pliers are helpful as well.

Be careful removing support material! It is easy to slip when applying pressure to tools and prints. A tool slip can lead you to injure your hands. Use caution and think about where tools will travel when applying pressure!

NEVER use tweezers to remove support material! Tweezers are delicate tools meant for gentle lifting. The force required to remove support material would damage tweezers.

Be sure to throw out all loose filament and detached support material. Look around the printer and clean up any filament or debris. You should leave the printer clean and ready for the next maker!
