I met Bill at RMRRF in Colorado last spring and bought this unit in November. I have a couple questions about general installation and klipper integration.
is there a required/recommended length of the filament PTFE between the load/unload motors and the Y? I'm using a core XY and it seems intuitive that shorter input tubing would always be better. How short is too short?
I have an SFS. Is there a way to integrate that with klipper to disable its sensing when loading and unloading filament to maintain its functionality? I found some information about using 4 optical sensors as runout sensors on the 4 filaments, but I don't know where the plans are to print the mounts. I'm interested in more information on that.
I'd like a klippy. Is this mounted close to the hot end typically? Details on it are sparse. A recommended model link would be helpful. Detail are sparse. One concern is if it is mounted with the Y on the moving print extruder that it will be too much mass and affect the printer speed.
If there are 2 extra motor driver channels on my printer board, is there a way to bring all the code onboard a klipper setup to manage the color change functionality? This seems like a great addition and the circuit board would not be needed.
For now the goal is to set it up to trigger off of a klipper IO without the microswitch and have the gcode call a macro to trigger it and set up the hardware to Y into the reverse bowden before the SFS and see how it goes.
thanks for any help and for insight.
Ok so maybe that wasn't specific enough to get help.
It is being installed on a V1 Engineering MP3DP (milled printed 3d printer) version 5 with a BTT H2V2s direct drive extruder.
I'd like to put a klippy on it and add runout sensors, but what orientation is the klippy mount to be printed and where is the stl to print the runout sensor mounts?
The steppers are connected on the 2 spare octopus channels with TMC 2209 drivers (not ideal?) and configured and functional in that they turn on and move, though they are not working correctly in klipper yet. Figuring out some of the constants and verifying movement directions are correct is next.
Is there more information on the encode setup? I have a couple encoders on hand that could possibly be used. More info on this would be useful.
Thanks.
Hardware is connected. I'm concerned the Y attachment teflon tubes are too short and may bind. There was enough of it though that it can be moved if needed.
found this page: https://www.3dchameleon.com/forum/support/klipper-macros-for-directly-connected-steppers-from-the-chameleon and that klipper code for #4 above.
Still need 1-3
