@pverdin That's a very broad temp range. Based on the picture, I would recommend starting at 240C - keep all other settings the same (if you're using the NylonX/NylonG profile). Post a picture of that and we can go from there. Also, if you want to just print a small calibration cube, that would be fine, too.

@mpirringer Adding desiccant packets to the print dry can certainly help. If nothing else, it speeds up the drying process. And if you're in a very humid environment (80-90+% rh at room temp), it may be necessary for some filaments. The vast majority of people will not need them. For those inclined, they have rechargeable tins of desiccant on Amazon for about $10. They come in aluminum cases and are color changing to indicate saturation. They are a lot easier to deal with that the paper packets.

@pverdin That's our mistake then. We can send it out if needed. Please let us know.

@mpirringer I am guessing that Tom and Taulman is suggesting that the filament is cold enough to cause dew to form during the drying process in the print dry, which would cancel out the drying.

You need to know the relative humidity in order to know the dew point. The dew point at 70C, with a 70% rh, is around 62C.

So, the filament would need to be at 62C or lower in temperature in order for moisture to condense out of the air.

This would be difficult to do given that the air is constantly at 70C and is heating up the filament.

Further, it would be highly unlikely to be at 70% rh at 70C. You would need to be adding moisture to your air.

The print dry works for virtually all currently available filaments, in nearly all ambient conditions.

@erievon It is under warranty, though that isn't really a warranty issue. If you're uncomfortable re-positioning the pulley and tightening the screw, we can do that for you. You would just need to disconnect the extruder motor and send it in.

It's pretty easy to do yourself, though. If you'd like help with that process, please email support and we can take care of you quickly.

Hi Martin,

We regularly use the power resume feature, and test it rather frequently. Does MatterControl prompt you that the print failed and ask if you want to try to resume it?

What kind of nylon filament? There are lots of different kinds, and they print in a fairly wide range of temperatures and settings.

@pverdin You are missing the retaining piece for the mount. It goes over the top of the heat sink and holds it in place with 2 screws.
It's part 512 - Groove Heat Sink Lock_A

You'll definitely want to print and install that.

Martin, thanks for the input, but that's not true. Unless you are in an extremely humid environment (90+% rh), NylonX will properly dry in the PrintDry at 70C. If it is fully saturated, it can take up to 12 hours to properly dry, but generally 4-6 hours will get it dry enough to print properly.

Hi Jacob,

The DXE doesn't have EEPROM - that's only for the 8-bit electronics.

You can adjust steps/mm on the DXE, but it's a different procedure. You just need to send the appropriate G code to change it.

Though, based on what I see, I don't think retraction is the issue here.

Give me a call or reply to our last email and we can troubleshoot the PLA issues in more detail.
