Hi guys,
I'm playing with my new extruder and would like to know how much it extrudes in a real print.
Is it possible to display extrusion volume in DWC? Printspeed, layerheight and layerwidth? should be available for calculations.
I extruded in free air to get ballpark numbers, but real life is different.

Displaying current extrusion volume possible?

RE: Music skipping beats after firmware update (3.4.0beta6)
@gtaman
It's actually the same:- create a global variable blockDaemon
- set global.blockDaemon = true at the start of the M300 file
- set global.blockDaemon = false at the end
Then anyone using Daemon.g for real can add these lines
while global.blockDaemon = true G4 S1000

RE: Hollow shaft extruder
Had my first simpleFOC project running today. It was an old brushless gimbal controller without encoders and with 8bit mcu.
I was able to control two motors independently and relatively smooth (USB power only)
The atmega328 was also at it's limit, but I'm now confident it will work well with the right mcu. -
RE: External stepper drivers (TB6600) on duet 2 wifi
@m0ck1nj
Check the TB6600 datasheet. If it is OK with 3.3V signals on step, dir, enable you can wire it directly.
If it needs differential signals or 5V you can use the much cheaper expansion breakout board -
RE: Hollow shaft extruder
First print today
Instead of a benchy, I tried the extruder-woodgrain test. Yes there is some, but hardly visible. The corners were sharp and even, that was a relieve. The close loop PID setting are quite soft, so I expected worse...
At the top third, the printspeed got so low, that the filament overheated. 10°C less temp and it was nice and shiny again.

RE: Accelerometer Usage
According to this picture
- positive X goes to the right
- positive Y goes to the back
- positive Z goes up

RE: Smart Effector including toolboard-capabilities?
@dc42 said in Smart Effector including toolboard-capabilities?:
It's clear to me that the Orbiter could not be used with a Smart Effector made to the current dimensions. We would need to increase the rod spacing to at least 80mm in order to accommodate the various parts of the extruder. We are looking into this, however it would make it unsuitable for the smaller delta printers.
Hi dc42,
I just stumbled across this thread and wanted to guide you back to 2016 , when we discussed the cycloidal direct drive. (I still have it laying around)
I've made an 45 degree adapter for it, that suited the smart effector pretty well.Another way to mount it, was the split motor/gearbox idea.
I could try to reuse my motor and design a BMG-drive for the Smart effector?

Display current back EMF for tuning
Hi devs,
based on the "extrusion volume" thread, I also think a back EMF calculator as DWC plugin would be helpful for tuning.
The required parameters are almost completely known for the calculation. It only misses coil resistance and inductivity (AFAIK)Since my Duet boards run on their own network, I don't have access to the EMF calculator at reprapfirmware.org
If we could integrate it as plugin and use 'live' values from the current object model/gcode file, we'd have a nice tuning tool

RE: Add 'pre-retract' and 'post-retract'
@nikscha I like the idea. It's like the tool-change macros.
But there is also a problem when you retract / unretract within a toolchange.
Maybe you can solve your problem by renaming G10/G11 to G10.1 and G11.1 via postprocessing. Then you need only one macro for retraction (which also contains the real G10 move) -
RE: HELP! New Cast Alum. Bed doesn't seem to AutoMeshLevel
One thing not mentioned by anyone is the G31 probe offset. Are you sure it's OK?

RE: Referencing single-quote axes
I have at least three symbols on my keyboard looking similar:

Just wondering if it was a typo error? But then the FW upgrade seems to work, maybe it's more typo-tolerant ?

RE: duet2wifi servo control by cellphone
@Pertti I think btncmd (buttoncommand) is the better option for you.
AFAIK, you can build your own control screen and control Duet2 via buttons and sliders -
RE: Generic voltage sensor
@drivetrainsystems
Also use B and C values :Additional parameters for linear analog sensors Fn F0 = unfiltered (fast response), F1 = filtered (slower response, but noise reduced and ADC oversampling used to increase resolution). F1 is only available when using a port intended for thermistors, not when using a general input port. Bnnn The temperature or other value when the ADC output is zero Cnnn The temperature or other value when the ADC output is full scale

RE: RRF 3.6.0-beta 2 tool fan controls disappear
@edsped IMHO it wasn't false alarm.
I guess, when you started a new print while the fans where still running in thermal mode, they disappeared?
Although you reconfigured them to direct control at the start of the print?Or was it the other way round?
Nevertheless, the fans (and DWC) should act the same in both scenarios. -
RE: Hollow shaft extruder
@rqthree Nice find!
I started looking for a wood lathe and the turning tools I'd need and guess what I've found:
Wood turning Tungsten carbide round cutter
They come in different sizes from 8.9mm to 16mm dia. A set of 10pcs is ~18€ which would be a lifetime supply for our usecase

RE: Modix Big meter in duplicate or mirror mode
@lorenjz I'm sure it's possible.
I have built a 4-head printer and tested mirror mode on all 4 tools.
IDK if I used the official way of doing it, but by juggling with:- redefining the endstops,
- reversing some steppers direction,
- modifying the printer kinematic-definitions and
- setting tool offsets,
I had a working solution.

RE: Sharing code, 1 trigger, 3 functions
@gnydick Nice idea
It could easily be adapted to- pause print
- cancel print
- shutdown power
Just wondering, if it could also debounce the pushbutton for the first usecase

RE: Macros & BtnCmd pannel for jogging a delta printer
@fšk If I understood you correctly, you want to use the dials to find the right tool-parking path's and end positions?
But the panel doesn't show the actual position? Is it on a separate screen? -
RE: Tuning the printing speed on fly
@Tinchus @dc42 I think, his intention is to constantly measure the slightly uncontrollable flow and change the printspeed instantly. (good bye planner queue)

RE: Can this 5-axis FDM be configured with RRF?
@JoergS5 said in Can this 5-axis FDM be configured with RRF?:
built as spherical, i. e. the three axes cross in one point.
Just out of curiosity:
This crossing point is necessarily the tip of the nozzle? Or nozzle + layerheight?
