@zincroots We use Taulman 910 and the layer adhesion is great if you print it right. We have not made dies though but lots of gears and brackets

If its on the bowden side. You can also use a zip tie of just the right size and pull the black thing up a bit.

@rjderama Take it apart. If you can't get the black stuff off the nozzle then a new nozzle it is same with the heatbreak. I tried heating and sanding it but it kept leaking then seems the little scratches you make sanding are enough for a leak. You can clean the threads out by running an m6 through while its hot if that does not work then you also need a new block. It pays to periodically check the nozzle tightness with a torque wrench.

@rjderama A picture would be helpful. Make sure you actually dried it and its dry. Most PETG needs to be printed from a print dry as even if its completely dry it can be wet again in 30 min to an hour. It depends a lot of the environment and its summer so in general more humid than in winter so it gets wet faster.

You could also have extrusion problems. Sometimes the nozzle comes a little loose on a V6 and you start to develop some blockage. if you got some black stuff (burnt filament oozing out either around the nozzle of on top of the block between the heatsink and block you got to take it all apart and give it a real good cleaning and possibly replace the nozzle and heatbreak and possibly the block.

@larsbrubaker As I said I love the bed leveling part and the other things I just mention in the hope for MC to come to the point that we can use it too. There is a lot to like like printing directly from it without having to use something like pronterface. IMO MC is soo close to be a great piece of software. I agree for many it might work. I have no problem taking this discussion private if you are interested. I know we use printers in a way that differ from the way most people do. I give your company credit for putting forth a great effort especially when it comes to tech support and that is a reason why I am still here doing what I feel help out a bit here and there. Now you got my number an I have no problem giving suggestion and/or trying things out. But I will always call it as I see it from my pov. Yes we had issues and I am sad how some things went but have no problem on helping out - be it MC or the pulse or whatever. And remember - there is always room for improvement

@larsbrubaker Mattercontrol has a lot of neat features now if it had a good slicer it would be a great program. Heck bring back the feature from 1.7x where you could link to Slic3r and have it link to prusa slicer which basically is lic3r and you got a real good program. The reason I stopped using it and am not using it for any of my other printers is the slicer and the annoying way you (maybe by now used to) do updates by simply adding or removing or moving something and I had to spend all kinds of time finding it - but mainly the slicer. There are a lot of things missing especially if you print with bigger nozzles (.6 and up) Your Bed leveling is great - but I guess I am repeating myself - get a good slicer. This is probably the last time I do that but
Variable perimeter width like specify layer width for outside and inside perimeters. If I use a .8 nozzle it makes the perimeter width .8 now .88 to .96 gives you better layer adhesion and for inside perimeters you can go even wider - depending on your nozzle and extruder

Max volumetric E - which goes with the above - you can read some tutorials here https://workbench.grabcad.com/martin.pirringer-2/tutorials I worked that out with the ppl from E3D and slice engineering and it works great and makes nice neat prints much stronger and faster especially if you are printing mechanical parts.

And Adaptive layers - can make a huge difference in both speed and accuracy. And they also need the max volumetric E unless you are running a .4 nozzle

So MC should come with a note with the current slicer "Only use for models to look at and not mechanical parts and only print with a .4 or maybe .5 nozzle " those are the most egregious shortcomings. But I was told by tech support that the slicer is not a priority and so I switched to prusa slicer and only bought printers (not from you) that can easily run with Prusa Slicer and don't need MC and the quality and mechanical integrity of our robotics parts drastically increased. Its a shame - I really loved your bed leveling thing

@rc50 You might have to play with the com port and the baud rate.

@pverdin Seems to be here https://github.com/RSteel517/Marlin-1_1_9-PulseXE-

@rc50 Create a custom printer profile

@rjderama Glad you found a workaround. And with the filament feeding.... TPU is fiddly as it got about the consistency of a wet noodle. A lot in printing is still trial and error
