@mpirringer I find it humorous that you posted an article with this as the first line in the conclusion, "Although short fibre-reinforced composites offer better mechanical performance than their
unreinforced counterparts, there is still a certain gap between the mechanical properties of preimpregnated
fibre and conventionally manufactured fibre-reinforced polymer composites."

This is precisely the point I made. Furthermore, the research paper cited literally only tested CF Nylon for impact resistance, not tensile strength like my data

I spent nearly a decade doing injection molding. The fact that you suggest that "science" says otherwise about the strength of composite materials with chopped fibers means that you simply have zero experiential knowledge on the topic.

@mpirringer I only provided stratasys info so you wouldn't accuse me of cherry picking data.

Here's a batch I ran on the unfilled PA12

These tests didn't have the extensometer installed, so the elongation and strain data is missing, but you can see the tensile strength.

Also, just to make sure it's noted for you - so there are no other excuses - this is the same base resin as NylonX, but it was natural/uncolored - whereas the NylonX has some black colorant used because the CF is black and it doesn't look good when it's not black nylon to match it. The black colorant is not adding to the strength.

So please, stop spreading the bad information that CF- or GF- filled filaments are not stronger than unfilled. They absolutely can be - and with nylon filaments, it's a fairly large increase in strength.

@rbradford1111 the stock NylonX profile is what is used to print the Phil. And it is glued down - but only with the elmer's stick that is included with the printer

Also, all of the parts on the Pulse are printed using the default Ryno profile with only 1 difference - layer height.
Some parts on the printer are printed at 0.25mm and 0.30mm layer heights, while the default profile is 0.20mm.

The profiles we provide should work well for a large number of parts, but there are definitely settings that need to be adjusted for certain geometric conditions.
We're not trying to hide anything or cherry pick settings for parts - the profiles we put in MC are the ones we use on the print farm for Pulse parts and for the print testing that happens on every Pulse printer - so if you are having issues with print quality, or have questions about certain settings, please let us know.

@mpirringer You know that we've been using chopped glass and carbon fiber in injected molded nylons (and other plastics) for decades now because it makes them stronger, right?

As for our data...
Here's one group of ISO 527 tests I ran on NylonX.

NylonX has a Nylon12 base resin. For comparison, here is Stratasys PA12 TDS
https://www.stratasysdirect.com/wp-content/themes/stratasysdirect/files/material-datasheets/laser_sintering/prototype/LS_Nylon_12_PA_Material_Specifications.pdf

So, on average, NylonX is about 23% stronger in tensile than unfilled 3D printed PA12.

Other CF Nylons use PA6 or 6/66, which have higher tensile than PA12. The CF versions also have similar increases to strength.

@mpirringer You are quite incorrect about tensile strength. NylonX and NylonG are significantly stronger in tensile than raw nylon filaments, and I'm happy to share ISO 527 testing data that shows as much.
Also, nylon actually adheres quite well to the fibers - particularly glass and kevlar - as we have seen virtually no drop-off in interlayer adhesion when performing ISO 527 test in the ZY orientation of the tensile bars.
There are lots of benefits of composite nylon filaments. Others, like PLA, don't provide much in the way of benefits, but nylon definitely does.

@justinmreina you can use the Palette 2 with the Pulse

@kentishduffer Are you using the controls to manually extrude or retract filament when it's paused?

@dogger15 to change the E-steps, and store them to the config file of your machine, go to the Terminal window and enter

M92 Ennn

Where nnn is the steps/mm that you calculated.

Then, after that's entered, send an M500 command to save them.

@kentishduffer I'd guess that you have gcode in your Resume G-code that tells it to feed 20mm on resume.

You can view that on the Printer tab > Gcode > Resume Gcode

MatterControl PRO has a Gear generator now. You can specify height, tooth count, pitch, ID, pressure angle, and clearances. You can also create a rack.
