Description

M33 Fio is a plugin for OctoPrint that extends its capabilities to make it fully compatible with the Micro 3D printer. Both OctoPrint and M33 Fio can run on Windows, macOS, and Linux, so this solution is the first platform independent option available for this printer.

The latest version of M33 Fio is V1.21 released on August 4th, 2017, and an entire changelog for it can be found here.

Features

  • Platform independent
  • Open source (M33 Fio's source code can be found here)
  • Supports STL, OBJ, M3D, AMF, VRML, COLLADA, and 3MF file formats
  • Allows printing multiple objects together
  • Displays an accurate representation of the printable region
  • Objects can be manipulated, cloned, cut, and merged
  • Displays an objects dimensions
  • Multiple printer support
  • Fully customizable slicing profiles
  • Accurate bed calibration
  • Supports the Micro 3D compatible heatbed
  • Firmware updating system that allows installing official and third party firmwares
  • EEPROM management
  • Webcam streaming
  • Changing filament in the middle of a print
  • Compatible with the Micro 3D open source firmware iMe

Installation

There's installers available for Windows, macOS, and Linux that install OctoPrint, M33 Fio, and device drivers for the printer and heatbed. These installers all add OctoPrint as a startup program and create a shortcut on the desktop that allows accessing OctoPrint's user interface.

If you already have OctoPrint installed, M33 Fio can be installed directly from OctoPrint's builtin plugin manager by searching for it in the plugin repository.

Usage

You'll need to disable M33 Fio's "Not using a Micro 3D printer" setting in OctoPrint's settings in order to use this plugin with a Micro 3D printer. After that you can immediately connect to a printer and start printing. M33 Fio works in conjunction with OctoPrint's auto-detect serial port and baud rate features, so neither of those values need to be specified in order to successfully connect to the printer. After connecting to a printer, all of that printer's existing settings, like backlash and bed calibration values, will be read in and used by M33 Fio to make transitioning over from M3D's official software as simple as possible.

OctoPrint uses external slicers to convert 3D object files into printable G-code, and, if you currently have M3D's official software installed, M33 Fio will automatically configure OctoPrint to use the Cura Engine slicer that comes with it. However I recommend installing the latest Cura V15.04 release so that you can enjoy all the latest improvements to the Cura Engine slicer. After a slicer is installed, printing a model is as simple as dragging and dropping a file onto OctoPrint's user interface.

OctoPrint is a web server, and it can allow remotely connecting to it. So you can open port 5000 in your computer's firewall and configure your router to route all traffic on that port to your computer to allow using your printer from anywhere in the world.

Known Issues

  • Everything works in all versions of OctoPrint >= 1.2.0 except the Micro 3D printer connection routine which only works with versions of OctoPrint >= 1.2.5
  • Microsoft Internet Explorer 11 doesn't display webcam stream since it doesn't natively support MJPEG videos
  • Microsoft Internet Explorer 11 doesn't resize slicer profile editor correctly
  • Microsoft Edge displays webcam stream as a still image
  • Can't host more than one webcam stream at a time since it always hosts on port 4999

Images

Additional controls are added to OctoPrint's control panel that allow doing everything from loading filament to updating the firmware.

M33 Fio allows changing all of the printer's settings in the M33 Fio tab located in OctoPrint's settings.
alt text
The slicer profile editor lets you quickly specify the quality and fill options of a print while still giving you the ability to fine tune every available setting.
alt text
The model editor allows manipulating the model before it's sliced. It can perform all the standard operations like translating, rotating, and scaling models.
alt text
It can also clone and import other models to allow printing more than one model at a time.
alt text
It can even cut and merge models to make even large models printable.

Troubleshooting

Q. I can't connect to the printer. I receive an error similar to, "Unexpected error while connecting to serial port: AUTO SerialException: 'could not open port 'COM13': WindowsError(5, 'Access is denied.')'" every time I try to connect."

A. Close M3D's official software if it's open, and make sure no other programs are currently using the printer. If the problem persists, then restart your computer.


Q. I receive a message similar to, "It's recommended that you disable this server's sleep functionality while printing if it's not already disabled." What does this mean?

A. M33 Fio attempts to prevent the server that it's running on from suspending/sleeping while printing, and that message gets displayed if it is unable to do so. Don't be too alarmed by this message since it doesn't mean that the server will go to sleep. It just means that M33 Fio can't prevent it from going to sleep.


Q. I installed Cura, but the slice button next to the uploaded files is still grayed out.

A. If M33 Fio detects that Cura is installed, it'll automatically configure OctoPrint to use it. However OctoPrint isn't aware of that configuration change immediately so you'll need to refresh your web browser several times for it to take affect.


Q. How do I re-open the print session if I closed the web browser?

A. Just go to the same URL that you were at before and it'll re-open the same session. You might have to refresh your web browser several times if it doesn't successfully restore the session.


Q. Even though I have the heatbed plugged in, I get an error similar to, "Warn: Not sending "M190 S100", printer profile has no heated bed" when I try to use it.

A. M33 Fio dynamically changes the printer profile whenever the heatbed is plugged in, however OctoPrint will sometimes not immediately become aware of that profile changed. So either refresh your web browser a couple of times or unplug and re-plugin the heatbed.


Q. OctoPrint's terminal shows an error about how it couldn't determine the printer's baud rate when trying to connect to the printer.

A. Something caused M33 Fio to crash, so you'll need to restart it. This can be accomplished by restarting OctoPrint, which can be done by restarting your computer.


Q. Can I use this plugin if I don't have a Micro 3D printer?

A. Yes you can. M33 Fio is already setup to be used by printers other than the Micro 3D printer by default. If you having trouble connecting to a different type of printer then make sure that M33 Fio's "Not using a Micro 3D printer" setting is enabled.

iMe: The best firmware for the Micro 3D printer

by donovan6000

iMe

© 2015-2017 Exploit Kings. All rights reserved.

Description

iMe is firmware for the Micro 3D printer that attempts to fix the printer's biggest problem: limited software compatibility. iMe uses RepRap G-code protocol, so it allows you to use the Micro 3D printer with any 3D printing software that supports that protocol. It also features builtin backlash and bed compensation which makes creating good looking prints with other software possible since the G-code never has to be pre-processed beforehand.

The latest version of iMe is V00.00.01.25 released on August 4th, 2017, and an entire changelog for it can be found here.

Features

  • Uses RepRap's G-code protocol
  • Open source (iMe's source code can be found here)
  • Homing uses the accelerometer to minimize grinding
  • Builtin backlash, bed, and skew compensation
  • Prevents moving the extruder out of bounds in the X and Y directions
  • Faster printing
  • Allows configuring the steps/mm for each of the motors

Installation

The easiest way to install iMe is with M33 Manager, which is available for Windows, macOS, and Linux. Just connect the printer to M33 Manager and click the 'Install iMe firmware' button to install iMe.

iMe is also fully compatible with M33 Fio, and it can be installed from there as well.

Usage

Every time the printer powers on it'll be in bootloader mode, so you'll need to click the 'Switch to firmware mode' button in M33 Manager to put the printer into a mode where other 3D printing software can communicate with it. Make sure to disconnect the printer from M33 Manager or close M33 Manager before using the printer with other software so that the printer's serial port doesn't remain busy.

M33 Manager will let you know which serial port the printer is using when it switches it into firmware mode, so in order to use the printer you just have connect to that serial port at a baud rate of 115200 with the 3D printing software that you want to use.

Known Issues

  • iMe has no known issues, but M33 Manager has various issues related to thread management

Images

M33 Manager can be used on Windows, macOS, and Linux. In addition to installing iMe, it also allows manually sending commands to the printer in both bootloader and firmware mode which can be used to manage all aspects of the printer.
alt text
So far iMe has been tested on Cura, OctoPrint, Simplify3D, Repetier-Host, Printrun, MatterControl, and CraftWare.

M3D heated bed Mod

by stepcia

[Update 2]
ok found a killer combo:

  • USB warmer plug with 2.1amp wall adapter
  • Stone coaster to distribute the heat more evenly
  • Printbite found here http://mutley3d.com/Buy-PrintBite/ this will stick very well and allow effortless remove after bed cooled off

video here:

https://youtu.be/bzJ81AS92W0

[Update 1]
found a perfectly fit USB powered mug warmer and it is powerful enough to heat the bed
https://plus.google.com/+StephenCia/posts/iiBH3tArM7Q

Hi all,

Just wanted to share what I have done to my M3D. Here's a quick video showing the changes I made: https://youtu.be/MqZngtGUFiY

Basically I replaced buildtak with "zebra skin" and I put Mr.Coffee mug warmer inside the internal filament chamber. I also use M3D fio software found here: https://github.com/donovan6000/M3D-Fio

recently I've completed a 9hr40m print with the heat turned on for the duration of print. it has to be manually swithched on and off since it is not internally connected to M3D electronic. so this method requires someone to baby sit the entire process of printing. I would not recommend leaving the printing unsupervised. :)
