Re: Artemis extruder calibration question

It's currently set at 182.0 - I've run close to 3kgs of filament through my Artemis and I've had zero issues that weren't attributable to a bad slice.

I'm using Cura 3.1 with the SE300 profiles from the git repo - my only changes have been to the temperatures used.

Re: Artemis extruder calibration question

Were you extruding from the Duet control panel? If so, what does "F30" or "F15" mean? Note that you don't calibrate the extruder by measuring output at the nozzle, you measure remove the bowden tube from the extruder and measure at the point where the filament exits the extruder....

Re: My printer has gotten an attitude.

You should've gotten a Duet. Unless it's been added recently, the firmware the Smoothieboard runs doesn't use the excellent calibration system that RepRapFirmware does. :)

Re: Worn & eaten belts / bent Motor mount

That's some epic over-tightening there, Lou. :D The length of the t-slot isn't really that important - the critical dimension is the distance from the top of the bottom assembly to the bottom of the top assembly. That's why there are stop-screws installed to make sure that the distance is easily set...

The fuse is thermal Jim. If it gets too hot, it will do its job and die. :)

Re: My printer has gotten an attitude.

I had another thought about this around 4am... the firmware may be smart enough to know that it can't move all three axes at the same time due to the higher steps per mm, so it may move a single axis at a time in order to reach the desired travel point.

Re: My printer has gotten an attitude.

It might be speed related - .9 steppers require more steps, so a rapid rate that works fine with the 1.8s may not work well with the .9s. (just guessing here).

Re: Problems uploading to board

You can't just copy/paste like that and expect it to work. :) You need to open the Repetier.ino file from within the Arduino IDE in order for it to file all the files it needs.

Re: Hot end always ON!

This can happen if the Kapton tape on the thermal fuse isn't fully covering the fuse body where it mounts in the cold section of the hot end. If any bare portion of the fuse body comes into contact with the hot end, it will result in the effect you describe.

Re: First homing: horrible grinding sounds

I suspect that you were seeing the effects of the bowden tube pressure being relieved - I still think there's something wobbly with your temperature reading - those IR thermometers are fairly useless when it comes to 3D printing. I've always checked with the thermocouple wedged into the "corner...

Re: Problems uploading to board

What OS are you using? do you have the correct port & board type selected in the Arduino IDE? Don't forget, you need to use v1.6.0 of the IDE when uploading firmware to the Rostock MAX. FYI, the "arduino" really isn't. The controller is called the RAMBo and is compatible with the Ardui...

Re: First homing: horrible grinding sounds

Ok, if you're seeing stringing with my gcode, you need to edit the file and drop the temperature 5C. Save it and re-run it. If it's still stringing, drop it by another 5. The lines to update are the M104 and M109 commands. I won't be able to try that "tiny columns" file until tomorrow. g.

You guys are missing the point on the Prusa printers. They're SUPPOSED to use 3D printed parts. That's the whole point of "reprap" printers - that they be able to contribute significantly to reproducing themselves and in a manner than is easily accessible to anyone. Trust me, if Josef want...

I'm printing this part right now. It's not so much a "stringing test" as it is a "let's see how much heat we can dump into two little plastic posts" test. :) When I ran the test I was using Atomic Gunmetal Gray, which is my go-to material of late. That part prints /very/ quickly ...

Re: Anniversary lamp for my sweetie

There's only one color of plastic. What you're seeing is why lithophanes are cool. I've made them out of Corian on a cnc router.

The "color" is controlled by how thick the area is - thicker for darker, thinner for lighter.

Re: Wear and Tear on the 8 pin connector of the HE280

You could try moving where the bowden exits the mesh loom in order to give the whip end more slack. If that doesn't work, there's no real harm in a little hot glue. ;) It should hold it well enough and still be removable if you needed to.

Also make sure the power supply is putting out at least 12v while the bed and hot end are heating up.
