Bigtreetech Scylla V1 firmware installation.
I think Scylla gets 10v form 10v pin on the VFD which is connected to AVR pin. And then it regulates the output in the SPD pin depending on dhe rpm value set on dwc, but problem is that it goes only to 8.3v max. I can losve this using an seperated PWM converter but was trying to avoid the headache of configuring that. -

Mellow Fly LLL Pro Filament Buffer
Thanks, I double-checked my menuconfig setup, and that was checked. I ssh into the printer and did an update, and the error seems to be gone.- 2

Bigtreetech Scylla V1 firmware installation.
Yeah, NineMile is not as responsive these days since he has a little one in his life now. In your VFD parameters, is there a "max voltage input" where you can input the voltage out of Scylla? djroomba has taken over some of NineMiles ' tasks; maybe he can help.- 1

Faster Printing requiring Filament Buffer feeding
Not daisy chained. In parallel. So each buffer has an address 0x10 for T0, 0x11 for T1, etc. When doing a query the macro will call the python script and tell it which address it needs to talk to. That goes out on a common bus and only the properly addressed one takes the command or replies as needed. Below is an example of a simplified move command for illustration: If i want Buffer_0 to move forward by 20mm. I would do `BUFFER_MOVE_0 distance=20` for pushing to hot end or `BUFFER_MOVE_0 distance=-20` for pulling back to buffer. That would take all the below defaults for the other options and send a command to the 0x10 address as configured int he "Main Variables" block _VARS at the top of the file. That command is grabbed by the python helper and send to the CP2112 via USB where its then placed ont he I2C bus and goes to all the buffers. It's ignored by four of them. The 5 one that has the proper address would start moving. The second section of the macro is id i used the "wait" paramater. That for macros use in klipper. So i want it to move the 20mm and assume it is fine or so i want to wait for it to finish before i do the next thing. This could be like a load operation. If i want it to be at the hot end, command a move, as its moving i start rolling the extruder there may or may not be filment there to grab. So i want time/distance amount of milliseconds. Its not a "positive confirmation" but its close enough that the hard was a chance to get the job done before i do my next commanded thing. [gcode_macro BUFFER_MOVE_0] description: Move Buffer0 a bounded distance using firmware MOVE_DIST gcode: {% set vars = printer["gcode_macro _LLL_BUFFER_VARS_0"] %} {% set distance = params.DISTANCE|default(0.0)|float %} {% set speed = params.SPEED|default(0.0)|float %} {% set wait = params.WAIT|default(0)|int %} {% set auto = params.AUTO|default(0)|int %} {% set max_dist = vars.max_move_distance|float %} RUN_SHELL_COMMAND CMD=lll_buffer_cp2112 PARAMS="--addr {vars.addr} move --distance {distance} {speed_arg} --max-distance {max_dist} --allow-motion" {% if wait %} {% set wait_speed = speed if speed > 0 else vars.default_speed|float %} {% set wait_ms = (((distance|abs / wait_speed) * 1000.0) + vars.move_settle_ms|float)|int %} # Give firmware time to complete the bounded move before Klipper continues. G4 P{wait_ms} {% if auto %} # Return to native sensor control only after the bounded move window. BUFFER_AUTO_0 {% endif %} {% endif %} Maybe more than you cared for? Not sure if you were commenting in passing or asking, but here it is anyway.- 4
