aio + creality hotend

by kaighn80

has anyone seen or made a hotend carriage for the creality type hotend? im part way through finishing my dual extruder conversion but im after using the creality type hotend so i can use a 2 in 1 out version of that type. it means you dont have to worry about offsets because both filament lines come through the same nozzle.

Da Vinci Pro Clicking Extruder caused by Spring Tension

by Hagster

Since purchasing this machine I have really struggled to get good prints. There was a pesistant problem with the extruder clicking and eventually clogging the hotend. I spent a long time messing with extrusion rates, temperatures and mods to the bowden tube. I replaced the original tube with an E3D capricorn tube. I removed the weird clip from the top of the hotend mount and replaced the short tube with a direct connection through a pneumatic coupler to the filament sensor. The short bowden tube that was removed actually had a small kink in it. All of this made no difference.

Eventually while adding some extra pressure to the filament goung into the extruder i noticed that if i pulled the lever arm back slightly the clicking would stop. I found a small bit of plastic to wedge the arm open slightly and it was transformational. Basically the extruder spring is much too strong and is crushing the filament. This has two effects. Firstly the filament is no longer round and will not fit into the hotend. Secondly after a retraction, the extruder idler needs to 'climb' over the step in filament thickness between the crushed and uncrushed filament.

BuildTak Flexplate system

by dheruer

Today i got the BuildTak Flexplate in the mail. Here are some pics of the unboxing/wrapping;

Now i’ll guide you through the installation of the BuildTak Flexplate system.
https://www.buildtak.eu/product/buildtak-flexplate-system/

It’s a very easy and simple installation, which anybody can do. There is an easy to follow instructioncard included in the box as well, but this will let potential buyers see the ease of installation.
The only ‘tools’ you’ll need are some acetone or other cleaner for your printbed, some cloths/kitchen towels and preferably a creditcard or small squeegee.

First you should prep your printbed. In a previous tutorial i showed you how i made mine swappable.

This came in handy today. If your printbed is still fixed in the printer, don’t worry, the steps will be exactly the same you only will have some less room to work with.

Step 1: Clean the printbed.

Step 2: Place the magnetic base of the BuildTak Flexplate system.

Step 3: Remove the warning sticker from the flexplate.

Step 4: Place the BuildTak sheet on the flexplate.

Step 5:Hard work is over! The flexplate with the BuildTak sheet on it is now easily removable!

Step 6: The BuildTak Flexplate system add’s 3mm to your printbed’s height, so be sure to adjust the Z offset!! I also strongly advice you to recalibrate.

Step 7: When you’ve done the Z offset adjustment and recalibrated your printbed you’re done! Happy printing! I had to increase the Z offset by 3.6mm!! to get my printer working.

When warming up, the flexplate system seems to be 10-15 degrees celsius behind on the printbed. I'll keep monitoring to see if it catches up.

Ok, it stay's about 10-15 degrees celsius colder after about 15 minutes of printing (and of course warm up time before printing) Also very noticeable and important to know is that the corners of the buildtak plate are much cooler! There is another 20 or so degrees celsius difference, about 2,5cm diam from the corners. (which makes sense if you take a close look at the magnetic plate, it's not a square.) So you'd need to set your printbed temps 15degrees or so higher then usual when using this system.

Da Vinci Pro 1.0 .3w files not compatible??

by Spearman

Bit of an odd issue that I've been trying to fix on and off for some months now. Went to print from Simplify3D for 1000th time and got an interesting "file not compatible" issue. Checked my settings to make sure I was using .3w, all was good. Still didn't work, so I reset to the default settings, no go. Went to XYZWare just in case and it still through a "file not compatible" error? I've tried quite a few things that haven't worked that I'll list below, but I'm hoping someone knows why this is happening?

  • Updated firmware
  • Updated software
  • Used XYZWare, XYZWare Pro, etc.
  • Downgraded firmware (all versions)
  • Tried all 3 .3w profiles in Simplify3D
  • Complete uninstall and reinstall of all 3D printing software, downgrade of firmware to original version it came with
  • Looked at Cura and cried that Pro 1.0 is the exception (why???)

I've considered trying to switch the board to a duino or something else, but I'm not sure if I want to go and mess with that when the problem shouldn't exist in the first place, and I had managed to achieve some good print quality just through my settings.

Please tell me there is something I've missed!
