Part 5 is now available and covers some upgrade options, including swapping the lead screw, adding a BLTouch, adding a buck converter for 12v accessories, adding LED lighting, swapping out the fans, etc.
technically, it's a cartesian printer with four printheads. Only 4 motors required for the XYUV gantry.
It allows several new and unique printmodes , which are currently not fully supported by slicers or printer firmware. So I disassembled it.
Maybe it will get a second chance in 5-10 years...
The old Mk None is being relegated to the status of "basement printer" while the Voron V2.4 is a great workhorse. I'm glad I stuck with a duet board since managing and creating macros was simple due to being familiar with it.
Years of backlogged projects are getting checked off. Thanks again, all.
@oliof One thing occurred to me, which is that with such extreme melt rates, a huge amount of part cooling air is required to prevent the part from collapsing into a semi molten blob of nastiness. Inevitably, some of that cooling air gets deflected back onto the nozzle, which is not necessarily "seen" by the thermistor. It is possible that a CHT nozzle might react differently to that deflected part cooling air (either better or worse). We'll find out in due course.......
You could try this paint, but instead of the method used in the film, thin the paint with paint thinner and spray it with a paint gun on the pcb. aliexpress has complete paintgun sets complete with compressor and tank for 125 US.
@chrishamm thanks, is there a way to drop a youtube video in here or can it only be a link?
Below is a picture of a nylon 6 print, works as well as a Multi-jet fusion part, maybe better. I think FDM has a lot of future, it was on the back-foot for a while but it still has a long way to go. (plenty of good refinements coming along) our latest print heads are making a big difference.
Just out of curiosity, now that the drive mapping is added, would it still be necessary to have separate jerk-, acceleration-, etc- setting for the second extruder?
Is it even possible to have different settings?
Yes. Extruders are considered as independent axis and should have all settings defined for each extruder and those settings can be different.
For other axis like XYZ you only need a single value for that axis. You must use identical motors for axis with multiple motors and you cannot have different settings for each motor.
All the time is overextrusion. Think i missed something in prusaslicer, swapped to ideamaker and quality is much better!
After that I started to checking everything, and when I was printing with infill less then 20% was ok. When increas infill getting worse. I changed infill overlap to 10% and infill flowrate to proper amount and now is perfect!
So I took a sliced file and randomly chose 3 different points to calculate the steps per mm. The ratio is between 7.3 to 7.5 XY steps to E steps.. Don't think they're lining up too well in terms of pulses. Still have my doubts on what's causing this, as it seems to be the result of several things lining up to create it..
Ah right! I'm using some of the colours for different functions such as completed prints, paused prints, cancelled prints etc. I'm not currently planning on using all of the colours though, but at least they're available for future use.
