  @sugarhood-nye I like print PETG on sanded Garolite, no glue needed. Or I also use borosilicate glass and hair spray. A textured PEI plate can also be printed on. Garolite is my favorite. Try these settings Nozzle 2740-245C Bed 75C (80C for Garolite) First Layer 10-15mm/s Additional layers 25mms perimeters Infill 40mm/s Fan OFF (never use the fan until absolutely needed)

  If at first you don't succeed, try, try, try ten times again... I am not sure why such a simple project took me so many times to complete. So I finally got the idler the correct size with the Gates machined pulley. The original pulley is smooth with a 3mm bolt shaft. You are not supposed to use a flat pulley on the tooth side of belt. I used the M3 bolt, but with a 6mm aluminum spacer. Works perfectly and will keep the teeth fresh.

  I own very large industrial printers which use these larger nozzle sizes. I disagree with the part being stronger with larger layers. And you lose your precision around hardware openings. Just because they say it on Youtube, does not mean that it is true. These channels are opinion hosts. Take a look at my Pulse custom parts thread. I can give you my petg settings, but they will vary depending on your hotend hardware. I just designed and installed a new hotend which lowers the heat sink temperature for cleaner clear petg printing. If you have any questions, please feel free to ask. Or visit us on Discord here: MatterHackers Discord Server My clear petg. I prefer to print with clear, as the pigments tend to make petg "Goopy" to print.

  The Pulse firmware is available on Github. But you will need to compile a custom build for that board. Alternatively, if you follow any of my posts, you can add a Duet mini 5, use my compile which is already made. I have been working on a new electronics enclosure for this. In my opinion, Duet makes the best cnc boards for printing.

  @erievon It's a ying yang, they both have great features. Load Pursa mk3 profile on Cura. Then drop your gcode model onto MC to print.

  MatterControl will not allow you load the height maps in it's output code, so normally you would have to add it there commented out: ; G29 S1 ; load height map (remove comment, post export) You would then have to modify your gcode file post export each time before printing. ;G29 S1 ; load height map (remove comment, post export) Alternatively, you can add this gcode to your config.g folder in the Duet system folder near the bottom just above the custom tools section G29 S1 The latest height maps will be loaded each time you begin a new print.

  Lifted feet for the lower pulleys. Also smooths out the harsh shaking while printing.

  Even if you don't use the Gates modified tensioner, I am finding that the modified x-axis idle side bracket slides nicer than the original one with the original tensioner. I used a 8mm straight ream in the linear rod slots and they fit nice at snug. X Idler Gates Mod Tension Files X Idler Gates Mod Files

  NinjaFlex on a Pulse

  I bought a spool of Ninjaflex recently and have not had any unexpected problems on my Pulse-XE. The parts I have printed with it using the profile for Matterhackers flex filament were good - not beautiful, but functional. I think it's tough to tweak it in to get high quality, but what I got was adequate. One thing I would mention is that I pitched the stock Bowden tube and replaced it with a Capricorn tube of much higher quality and tolerances - That is important for printing with Bowden tube printers and Ninjaflex - You don't want a lot of room in the tube for the filament to bind against the walls.

  @intj123 I use no glue. Nylon adheres to exposed fibers on Matterhackers layer lock. After you remove your print, you must resand the surface.

  Hotends for Pulse XE

  @bedellkw I have both slice engineering and E3D hot ends. In my opinion, the E3D is better. The first time you get a clog in the hypodermic needle on the Mosquito, you will understand why I prefer E3D. I do not use a "stock" E3D. I have a E3D copper block, I use Sliceengineering heaters and p1000 thermo couplers and a titanium heat break. And I use a metalic nut on the threaded heat sink. To quick change the nozzles I use a nozzle t-wrench and a "thin" 16mm spanner to hold the block. With these proper tools, the nozzles are easy and quick to change. Use hardened nozzles only. If the nozzle becomes clogged, heat with a torch until cherry red. This will burn off the plastic, but ruin the tempered steel. With the cherry red nozzle, drop into antifreeze coolant in a metal tin can. This will re-harden the nozzle and you can continually use it this way.

  @cope413 Just to recap, when we started, the Z motors were dialed too high and acting up. Not sure if we determined why this was set this way... We then re flashed the firmware. PID calibration obviously is not working or providing us reasonable values... My first calibration gave me KP 7.74 Ki 0.19 Kd 79.95 My second calibration gave me KP 9.29 Ki 0.41 Kd 53.00 These kept the hotend 20c below the set temp no matter what I set it at. We then bumped those up to your suggestions (still not sure why a self PID calibration did not give us reasonable values) Now its getting higher but staying 3-4 degrees below set temp and fluxing heavily between 3-4c below set temp. This is with the nozzle even at HOME Z up and away from the bed. So what we still have is a lot of unanswered questions on why this specific printer is acting so strangely...to begin with. Spoke to David Gaylord and at this point, we both are just not sure why we are still messing with this printer when it clearly had issues early on....

  @cope413 Can someone ring me up for the parts I need to do a new snap hotted conversion...and a mosquito hotend as I'm sure this ones toast...unless I break out a blow torch.

  You can use OctoPrint. We just don't have guides/instructions to do so. You can also use any slicing software you choose, but you'll need some different start gcode in order to use firmware leveling.

  Definitely don't use that firmware. I'd recommend modifying the current branch of Pulse firmware for the Spider board.

  I also had a question on a separate topic about using octoprint with the pulse? If you know anything that would be great. And you mentioned that you have the duet electronics system, does this upgrade create better prints and if so how much was the upgrade all in and what components did you change?
