Thanks for the reply.

I tried the @PAUSE today but could not get it to do anything. Out of time now to try the other stuff you suggest until Saturday or so.

Is there any info available on how to use these commands and any other commands that may be available? I do have the book "3D Printing with MatterControl" but did not see anything about these commands in it.

As far as the M0 code it would be interesting to find the reasoning behind changing the function of such a basic command especially when a G4 Pnnnn command does the same thing. Every CNC I have run in the last 35 years a M0 will stop and wait until the operator presses cycle start.

I do respectfully disagree about "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." when I press that button it takes several seconds to the better part of a minute to stop.

Of topic, what is the difference between http://forums.matterhackers.com/ and http://www.matterhackers.com/community/forum which one should I be using?

I ask because the the editor in this one is not working properly on my computer, it goes off the bottom of the screen and I need to keep using the mouse to scroll it back up to where I can see what I am typing.

Thank you;

Hi Andre!

I was able to find the issue you reported, and am working to resolve it now. It should be fixed by the next time you use the forum.

Forums.matterhackers.com is the new matterhackers community. matterhackers.com/community/forum is being phased out in favor of this new forum.

If you have any other issues, feature requests, etc- please feel free to shoot me a PM.

Thanks, works much better now on my little laptop screen. On a larger screen with short messages it probably would not have been a problem.

One of the reasons I am looking into Matter Control is the ability to queue jobs then monitor and control the machine remotely is that when I got the Lulzbot Mini some of the people I work with wanted to see it so I brought it in. I made a few little widgets for use in the shop, stuff we have been wanting but never got a high enough priority to justify the time to make. With the printer it still takes some time to design and setup but then you go do something else for 6 hours and come back to a finished part.

Anyway another guy and myself got to talking and are now working on a design for a delta that should be able to do 3D printing and light duty machining. We would like to also build a "pallet pool" to work with 2 or 3 of the delta machines.

At this point it looks like a long road but everything should be doable.

@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.

Don't eat breakfast.

A few weeks back I ordered a Robo with MC-Touch (sounds like a pedophile rap-star doesn't it?!). They sent the MC-Touch on ahead of the Robo box... so I unpacked it and hooked it up to my most troublesome machine -- my CTC. Within an hour I had every problem I ever had with that hunk of junk under control. That easy. I tried it on my HICTOP Prussia -- great steaming bowls of mac-and-cheese what an improvement over Rep-G. When the ROBO arrived I reluctantly hooked it up to that machine. Wow. Aside from a minor mechanical glitch the ROBO took off right out of box.

I am a big believer in MC-Touch at this point, however I found the following shortcomings that need to be address. Perhaps in a Touch II or Touch Advanced format.

1) First of all the tablet is prone to overheating and stalling. 99% of my glitches happen when the tablet gets very warm to the touch. Provision needs to be made to cool the tablet better.

2) Connections: Lets look at where all the wires connect and devise a way to spread them out so they give us better mounting flexibility.

3) Larger screen: Put the program on a much larger easier to use tablet. It can be challenging typing on this thing! I don't see any provision to hook up a Bluetooth keyboard, though I haven't really poked behind the Matter Control shell very much. I went into Settings to change my security options that was it.

4) EMI Shielding: The remaining glitches come from transients in the power-line and EMI in my shop. The simple act of turning on the box-fan under the work-station stalled the tablet. As did firing up my mill across the room. Either the power-supply is passing transients through to the tablet, or the boards themselves are picking up EM spikes. Regardless, this needs to be fixed.

5) General Improvements: Clean up the UI a bit, make the buttons more responsive, and allow me to customize my experience (sounds, colors, layouts) and we'll be perfect. There are a few other improvements I'd like in the software, but I'll wait until I have more experience with the package before I detail them.

When it is all said and done, we're almost there -- it's almost perfect. Address these concerns and you'll blow all other control schemes out of the water. Will be buying a second unit as budget allows.

Just got a MatterControl Touch to use with my Rostock MAX 3D printer kit. Tablet has working WiFi set up.

Main interface shows a red "1" on the Updates link. When I click on it displays on screen "Launcher: Update Ready to Install".

Every time I click on it it switches to "No Update Available". Then when I go back to previous screen, goes back to showing that 1 update is available.

Have turned tablet off and back on several times, which did not help. Switched tablet from Dalvik to ART and re-tried, then back again, still no success.

Was successful in downloading and installing an available update to the MatterControl software.

Software versions:

OS: Android 4.4.4

MatterControl: 1.4.1.5565

Launcher: 0.0.1.5476

Hi, I have been using Simplify3d, and the estimated time for this model is said to be 6hrs. and I have found it to be fairly close.

On loading the same model file into MatterControl the estimated time given is 15hrs over double that of simplify3d, can anyone tell me why this should be.

Thanks, very helpful.
