Hey, Dave here from MatterHackers.

This category is a great place for you to introduce yourself, what types of machine(s) you are using and for what. Here are some of the basics everyone may want to know about you,.

I want to take a moment to thank you for stumbling upon the MatterHackers forum and contributing to the betterment of 3D printing. This space will grow and develop into a place for people to gather and learn more about 3D printing. The hope is that this becomes knowledge base and a broad platform for all involved in 3D printing (and those looking to get into the technology) to share your experiences with the intent of providing information for others to succeed with the technology.

Anything at all we can help with please do not hesitate to contact us directly.

All the best,

Dave Gaylord

You can see some of the projects I have worked on at https://hackaday.io/MrAnderson.

I am relatively new to 3D printing, have had a Lulzbot Mini for about 6 weeks now, but I have been running CNC's of all kinds for 35 years or so.

I was using Lulzbots version of Cura but I am looking to do more then it wants to do, also I can not handle the yellow/green ish colors.

One of the things I would like to do is in the middle of a print pull up, move off to the side and stop (M0) so I can change filament or inset hardware etc. I read someplace about a guy doing that with a supposidly stock Lulzbot Mini using Simplify3D.

I installed MatterControl a few days ago and have only done a few prints with it, liking it but still very much getting used to how it works.

I did a test, I exported a small 12 layer print to gcode, opened it up in notepad++ and inserted a line with a M0 at layer 6. Loaded it back into MatterControl and run it, it went right by the M0 line, it was in the terminal window but the printer did not stop.

So I am wondering how they are doing it in Simplify3D. Any ideas.

Thanks,

Andre B.

I want to be a part of the future of digital manufacturing.

A part of the molecular and nano-fabrication that will reshape the world.

Building with atoms - trees do it, our bodies do it, and soon our machines will too.

MatterControl does not yet have the ability to pause the print at a certain point, but that feature is on our short list for development so you can look for that in the next few months.

In the meantime, I think you're on the right track with the M0 command, although this only pauses for a specified amount of time so I don't think this is what you want to use. Also, your printer must be running firmware that supports the command-- which if you haven't flashed it with anything else should be running Marlin firmware by default which does support the M0 command. See the RepRap GCode article for specifics on which commands are supported by which firmwares and for general reference of commands.

That said, perhaps you did not issue the correct parameters after the M0 command? Not only must you issue 'M0', but also then specify how long you want the print to pause for afterward. Like so:

M0 P5000

Where Pnnn = P[milliseconds].

In any case, MatterControl has some commands which can be used in GCode or in the Custom GCode fields I'll explain in a moment:

@pause

@restore_xyz_position

@restore_e_position

These are unique to MatterControl and can be inserted directly into GCode which MatterControl reads. I suggest you use @PAUSE instead of M0, which as I explained before, has a hard time limit.

The other way to accomplish this pause is to do it manually-- which I recommend in this circumstance since you'll physically be there to change the filament or whatever you're doing. MatterControl has a 'Pause' button which shows while the print is running. Clicking it will, by default, pause the print at exactly where the nozzle is at that time. But, then you can get creative.

You'll use one of MatterControl's custom GCode settings -- Pause GCode -- to give the printer some custom instructions for when you hit the Pause button. Navigate to 'Settings & Controls -> Settings -> Printer -> Pause G-Code' and enter something like:

Then, when you hit Pause, the nozzle will move up 40 mm and over 60. Change the filament or whatever you need to do, then when you hit the 'Resume' button the nozzle will return to the coordinates it was at when the print was paused and continue printing.

For reference, any valid GCode commands can be entered in the Custom G-Code section, but be careful what commands you enter. The printer will follow instructions explicitly, and bad instructions can damage your printer. If in doubt, test your GCode using the GCode Terminal (Settings & Controls -> Options -> Hardware Settings) before you enter it in a Custom G-Code field.

EDIT: Added @ command information, formatting.

EDIT 2: Changed @PAUSE, etc. to lower case

I have a new Matter control Touch that I was able to send one stl file, from my desk top computer, to my Touch and print. I tried another file and it said it was too big. I changed the dimensions, several times, and tried to send; to no avail. I cleared that file and tried to send another file and received this message, Access to the path " _ _ _3stl" is denied." It shows the name of the file I cleared and not the file I'm trying to send. Can anyone help me regain access? Thank you!

Can you be a little more specific about how you're sending the files? Are you using MatterControl to send files from the desktop version of the app to the MatterControl Touch via the 'Send' option, or are you sending the files manually using a different method?

MatterControl 1.4 now has the Cloud Library feature which makes sending files much easier so that is now our recommended method for transferring files to the Touch:

Yes, I'm using MatterControl on my PC and I'm following the directions on, https://www.matterhackers.com/articles/mattercontr...

Okay, thanks for confirming.

We've seen intermittent issues with the 'Send' function referenced in that article, and Cloud Library is now the preferred method for sending files so I recommend you use that instead.

From the first link in my last post, navigate to the 'Adding Files' section for information about how to add files to your Cloud Library.

Use the second link to access the post about retrieving those files on the MatterControl Touch.

Let me know if you have any issues.

For calibration, the thickness of a sheet of paper is usually the best distance from the nozzle to the bed. Standard procedure is to use a piece of paper while setting the Z height using the LCD controls. Lower the nozzle slowly (0.01 mm at a time) and slide the paper underneath. When the paper no longer slides freely but is still able to move without binding, set the Z height to zero.
