@dwuk3d I watched the Proper Printing one last night, very entertaining! Will watch Ivan’s today.

@magnets99 The gantry is pretty interesting: They use the smooth rods for linear motion and as rotating shaft.
I wonder how well that works with these linear ball bearings? Especially on pure X or Y moves (i.e. homing) they will suffer.
I'd replace them with IGUS bearings if they seem to be worn out.

@_Djrema Hi, honored to have you here although my project ended early as a proof of concept only.

Slicers and controller firmware are just beginning to work with more than one nozzle, so it will take a while to see a working printer.
Another reason why I started the project is, the copy/mirror mode which was interesting at first. But since I own resin printers and learned their ability to mass produce parts, they are much more intriguing to me now.

Mirror mode for bigger parts would be a reason to build a #-printer, but the build-cost will explode.

take a look at my settings....

Here a few updates after I swapped my y axis , it working good , still need to modify my motor mount

Update, if anyone cares:

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.

Can you be more specific about what isn't working correctly?

Perhaps you should start with a clean config file from the online tool.

@giuseprap said in Z AXES DOUBLE SETUP:

M584 X0.0 Y0.0 Z0.2:0.4 E0.3
"for selecting the 2 and 3 driver for the z axes".
M574 Z1 S1 P"io3.in"
"for selecting the microswitch z for the two motors"

You have used output zero twice, I suspect Y should be 0.1

For two motors with separate limits, you need two inputs?
This is what I have (on a Duet 6HC):

M574 Z1 S1 P"io3.in+io4.in" ; configure active-high endstop for low end on Z via pin io3.in

@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.......

@thedragonlord
Sorry. Had been busy the last few days.
I use Prusa Slicer. There you can cut the STL and reunute it the size you need. One segment is 11.2mm wide.

I modified mine to 10 colors these days. Including it to my upsidedown Voron.
The Idea was to grant access to a Pilamentstorage underneth the printer.

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.

@lael they’ve been great, and I only need two sets. They are also often used in food service to connect/disconnect fluids like soda syrup, beer taps, etc.

Like you said, it allows me to quick disconnect the hotend for whatever reason without any major disassembly, or if I want to locally drain it without emptying the entire loop.

@chris94 no problem. you're welcome.

@o_lampe said in Request Cartesian with cyclops system: 2 extruders and 1 hotend:

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.

See the notes here: https://duet3d.dozuki.com/Wiki/Gcode?revisionid=HEAD#Section_M584_Set_drive_mapping

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!

@Veti thanks that seems to have done it

How do you manage the tip when removing filament? I always have troubles... I'm working on such system but with 6 filaments.
