Re: Error: during calibration after print errors

Sometimes the FSRs get cranky when they're too warm. I haven't had the issue with my Artemis, but I've heard it happening to others. The simple solution is to just calibrate with the bed cold.

Re: Error: during calibration after print errors

Are you calibrating with the bed hot or cold?

I'd check to make sure that all the stepper motor connectors have their pins fully seated in the shells.

The only time I've seen layer skip like that is when the nozzle struck the print during a travel move. What slicer are you using?

Trust me, this kind of nonsense isn't tolerated and it's *extremely* rare. I've been an admin on this forum since ~2013 and this is the 2nd time I've had to bark at someone and the first time I've ever issued an official warning.

Re: Anniversary lamp for my sweetie

I posted a warning to him. Your lithophane has similar characteristics to the hundreds of other engraved & printed ones I've seen.

Frankly, I don't know what his major malfunction is, but it won't be tolerated here.

Re: My printer has gotten an attitude.

Another big thing the DuetWifi has going for it are the stepper drivers. I've got one of them in Orange Menace - it's a Rostock MAX before there was a "v1" and it's a big echo box. It's nearly silent. I've got an 0.8.5 in another v1 and it's really loud - same drivers as the RAMBo.

Re: Worn & eaten belts / bent Motor mount

Apparently my reading comprehension skill was on vacation when I first read your post - it didn't register that you had different length extrusions, which is really an annoying problem. I'd recommend you shim the towers at the top to make them match the X tower - you want the top to be completely pa...

I don't think so. It's my understanding that the hot side is the common plane, not ground. (ground is switched...)

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...

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).

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.

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...
