@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.
