@Simone Eventually you have a high "first layer extrusion factor" ?

@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

@Alex-0 Thank you very much for sharing.

RE: X and Y artifacts (cartesian printers)
@FelixH Could it be that your idlers on the cartesian machines have no teeth (only a bearing)? Then you see the teeth of the belts which are running on a flat surface of the bearing as artefacts on the surface of your printed object.

RE: What's the correct way to determine if there is a job active?
@gnydick There is another posssibility with:
if job.duration = null

RE: 5v Part cooling fan
@handyandy it should be possible to wire the +5V to the "V fan jumper select 5V pin" and the GND to a "fan output(-)" like "Fan1-".
In this way you can control the fan speed with PWM. -
RE: trigger inputs not de-bounced?
@fcwilt Ok. I think it should be possible with a "Schmitt-Trigger"...
-
RE: trigger inputs not de-bounced?
@fcwilt I had the same problem some years ago. The trigger inputs are not debounced.
You have to program a "software debounce" with a delay and then read the input again. -
RE: disabling a tool in cura
@sonderzug @Phaedrux
thank you both for your answers. But i was not able to print with T1/T2/T3, without "touching" T0!
The only way was to define a printer with only 3 tools and use T0/T1/T2. -
disabling a tool in cura
Hello,
i have a toolchanger with 4 tools (T0-T3). In cura they are listed with Extruder1-4.
I like to print a model with "only" 3 tools (T1-T3). But it seems not possible to disable T0 copletely!?I have disabled T0 (Extruder1) in Cura, but it picks up T0 everytime for the prime tower!
Also, when i define the primetower for T0 to 0 mm3 volume. It picks up the tool, heating it and do the move to the primetower and back to the dock...Can anyone help me?
Thanks in advance. -
RE: Another Delta Homing Issue
@too-stroke Eventually it helps, when you insert a "M400" command between line 6 and 7.

@too-stroke can you please share your homedelta.g file from the sys folder?
