RE: Part cooling fan not strong enough
@andreic I think your ducts produces to much back pressure. You should test the fan in "free air" for comparison...

RE: heatsink for watercooled hotend, dimensions?
Sorry for answering to this old post. And this is only for info:
I have finished the work on my prototype watercooled hotend. Now it's ready to make first tests...
The heating block and heatbreak is from a DTO hotend.Here are some images

RE: Small UI BUG
@tinchus I think you can solve the problem with putting an ";E" after the comment semi-colon, like this:
G1 Z400 ;E drop the print bed (E to exclude from layer count)(Obviously, you need to be in absolute positioning mode for this to work)

RE: possibility to read tacho signals with lower rpm
This post is only for information and for closing this point!
The problem with my tacho signal is solved.
I have developed a signal multiplier/divider with a raspberry pi pico. The system is able to multiply or divide an incoming (tacho) signal with a factor between 1 and 15.
When i multiply my flowmeter tachosignal with factor 5, i'm allways in a range which RRF can read.If somebody has a similar problem, i'm happy to share my project.

@educatingsavvas i think T-1 should work

RE: possibility to read tacho signals with lower rpm
This post is just for info:
I have expanded this "TachoMod" project a bit.
Actual version is V4.0 with the following additional functions:- Raspberry Pico has now a small OLED-Display (with 2 buttons) for displaying datas and enabling a menu
- Tacho-signal period and rpm of in-/output is displayed
- Menu for changing multiply/divide mode, factor, timeout, pulse per revolution
- stores all settings on onboard memory
If someone is interessed, i can share the source code and additional infos...

RE: is a delayed triggering of the filament sensor possible?
@cr3d I don't know which macro is called when the filament out sensor triggers...
But in that macro you can "store" the actual Extruder Value in a variable, make your math, and call another macro after 50cm of extruding.
Eventually is daemon.g also a good option to put the code in... -
RE: Thermostatically-controlled fan
@agusano Which FW Version are you using?
Eventually you can invert it with a leading "!" in the M950 command
M950 F2 C"!Fan2" Q25000

RE: Precision Piezo Orion what material its better for clamp?
@peirof @engikeneer ASA is more or less like ABS. It's really good for outdoor usage, because of very good uv-stability. The max temp is approx. 90-95°C
Small parts are no problem to print without warping. For big objects a (heated) chamber will help.

RE: Not a perfect first layer
@Simone Eventually you have a high "first layer extrusion factor" ?

RE: Bloob on print
@claustro
Do you use retract ? Please posr the settings. Is it a direct drive or bowden? -
RE: Fast print results, what can I improve?
@claustro
Note the "wavy" inner wall. I think, this is the limit unless you make the system stiffer or the printhead lighter. -
RE: Multiplier for fan speed?
@janjoh
I had once a similar problem. My Duet2 was not able to read the low rpm of a flowmeter.
My solution was for sure a bit complex. But it was a cool experience, because it was my first project with a raspberry pi pico and phyton.
I have devloped a tacho signal "shifter". You can multiply or divide every incoming signal by 1-15.

RE: Filament oozing during delta calibration?
@KeithW
I calibrate my delta with 160°C too. If you see some differences, you can adjust the nozzle/z-probe offset in config.g -
RE: SSR on expansion heater
@dc42 Thanks for your answer. That's a good idea... it was not in my mind.
Do i need also a pull up resistor with the PS_ON pin? -
RE: SSR on expansion heater
@chrishamm It's a "A-senco SSR-500". The input is for 3-32VDC and it draws 6-20mA according to datasheet.
When i connect it to the expansion pin with 3.3V, i think it draws a bit more than 6mA.?Thanks for the hint with the resistor.

SSR on expansion heater
I'd like to connect a SSR to the exp.heater3.
Can i directly wire the SSR to the expansion connector? Or should i use a driver between?
The SSR input is 3-24VDC.Is the exp.heater3 output switching to ground?
If so, i think it is correct to connect the + of the SSR to the +3.3V on the Duet2 and the - of SSR to the exp.heater3?Thanks in advance
