I also wanted to let you know that we have been working to add MatterControl Pro to all Pulse purchases, and this will be retroactive to all existing Pulse owners.

@Andre-B,

You are correct, when clicking 'Pause' in MatterControl, the printer will not pause immediately. The machine has a number of commands queued up and it will not pause until they are all executed.

As to @pause working - Another programmer and I were just looking into that functionality yesterday. He was having some issues with it as well. After, a quick test it seemed to be working as expected, but we will investigate more and see if there is something happening here that is unexpected. I would try to make all of these commands lower case however. That is how they are intended to be added to gcode.

• @pause
• @restore_xyz_position
• @restore_e_position

Thanks for the feedback.

Hey guys,

I wanted to just add a little clarity from the engines perspective. Ryan has described the correct way to calibrate the printer, and even a little pressure on the paper can result in printer being at a true zero. But to be clear, if you could calibrate the printer perfectly, zero is zero. Just exactly touching the bed with no pressure at all.

Where is zero on a perfectly calibrated printer?

• The nozzle just exactly touching the bed
• No pressure down, no gab between them.

The print leveling actually subtracts out the paper width to try and get this exact calibration.

MatterControl 1.7.0 is out!

Hey everyone, we're excited to be getting up the latest version. It's been lots of fun getting this together, and we hope you all enjoy it.

This forum is a great place to ask questions; and if you find a bug, please head on over to our source code on GitHub and please report it.

What's new:

• Significantly improved tool paths, much better printed parts
• Improved macro support
• Improved baby stepping
• Updated to latest avrdude for improved compatibility with some non-standard boards
• Improved support for network printing
• Touch screen mode now works on all platforms
• New printing screen in touch screen mode
• Better screen position saving and restoring

Thanks for all your support, You can find the complete release notes here.

We are actually working on two solution that would help with what you are trying to do:

1. Set the desired layer height progressively throughout the print (variable layer height)
2. Add the ability to 'Re-Slice' anytime during the print and then automatically switch to the new gcode at the next layer change.

Look for this and other features coming into the new 2.0 build over the next months (and ongoing).

In the Alpha of MatterControl 2.0 (you can download here) you can see the total print time. You can also see details about each layer including: the time on the layer, the time to the layer from the start and the time from the layer to the end of the print.

This has been fixed. Please update to the latest build.

If you are on Mac you may have to change to the Alpha channel to get the fix. It will be in release in a couple weeks.

That's so good to hear. The team has been working very hard on it!

You can. If you just type MatterSlice.exe into a command line it will show you the required parameters.

The new build that fixes this is in alpha and should be released soon.

Are you using the Mac build? Regrettably we have not gotten the new subtraction library working on Mac so it does not work as robustly as the PC. If you have access to a PC you can try to do it there. It might not work though. Subtracting two meshes is an incredibly difficult problem and sometime it just doesn't work right.

It is under this button

This should now be fixed. You can switch to the alpha build if you want to try out the new build. We will promote it as soon as we prove it doesn't break anything else.

Sorry, there is not yet a reasonable way to do this.

The good news is it is very much on our wish list, but it may take a wile as there are many other performance issues that have to come first.

You can find the Release Notes here:

I am having the mm setting on top and bottom layers working correctly. Would it be possible for you to upload your printer profile and model that is failing in a .zip to GitHub? We would love to investigate the problem.

Thanks for posting to GitHub. It looks like you just need to add 'mm' to the settings. We will think about ways to make this clearer in the future.

Thank you for reporting this error. We have fixed it in the Alpha build and will be updating the main build as soon as we collect enough data to ensure that there are no other regressions.

If you test this build, please let us know that this fixes the error for you.

Thanks again.

MatterControl is used by tens of thousands of people successfully every day. It designs, slices and prints millions of parts. It is free software. It is a gift to those who want it. It is worked on with love and passion by dozens of people and it is improving all the time.

I posted this video to show one of the many ways that we work to improve MatterControl - giving insight into a tool (our automated tester) that might be exciting to some. I hope to inspire and improve the work of those who find this tool exciting. There are many slicing engines, and design softwares that people can choose from, and many choose MatterControl. I hope you have found the ones that work for you.

You frequently describe your opinions and experiences of the shortcomings of MatterControl. I ask that you be respectful of the many people who find value in this product and leave room for others to discuss the merits and utility they are finding, to share positive stories and experiences.There are many opportunities to describe MatterContol's shortcomings, you have been heard, please allow more of these conversations to be positive.

I made a video to show off one of the ways MatterControl gets tested. Every version has hundreds automated tests (401 currently) that run to ensure everything is working like it should. When we get bug reports, we add more tests.

If you search for:

			if (spiralize) // if we are still in spiralize mode
			{
				// If we need to spiralize then raise the head slowly by 1 layer as this path progresses.

in LayerGCodePlanner.cs you will find what you are looking for.

Checking 'path.Polygon.GetWindingDirection();' would allow you to reverse the points if they are not the direction you want.
