I have a toolhead not listed in the examples. I have attached the cad file if someone can help me guesstimate the values that would be awesome
#[solved] Need help calculating toolhead values

what i currently have
i cant figure it out using the pictures provided so any help is awesome

yes I did it always seems to pull the filament past the cutter too much jamming things when it retracts
buoyant stump
...so reduce retract
azure nacelle
like when i go to change lanes not normal retractions
I havent gotten that far yet i just got it to the point where I am trying its first lane changes before a test print... i just got the macros working correctly
this is a new boxturtle unit

Yes, ```# Distance to retract prior to making the cut, this reduces wasted filament but might cause clog
if set too large and/or if there are gaps in the hotend assembly
*This must be less than the distance from the nozzle to the cutter
variable_retract_length : 20```
Not retract in the slicer, retract in AFC_Macro_Vars.cfg
azure nacelle
ah i didnt see that value
how far from the nozzle should the be in theory like up past the heatbreak?
buoyant stump
what hotend?
azure nacelle
Im using a rapido 1 UHF
buoyant stump
I would start with 10 then, Rapido doesn't seem to like retract too much
azure nacelle
ok
buoyant stump
you'll also want to change pushback as they go hand in hand typically
buoyant stump
sounds right
azure nacelle
so if i measure from the cutter blade to the top sensor and add 8 for the pushback that should give me the tool_stn value
buoyant stump
more or less yes
azure nacelle
so so far
variable retract: 10
variable pushback: 8
tool stn: 14.418(cutter to after extruder gear sensor)+8(pushback) =22.418 (used bottom sensor since im using 2)
and stn tool unload is from the nozzle tip to past he top sensor right?
and what for this value tool_sensor_after_extruder: 0 # Extra distance to move in mm once pre/post sensors are clear. Useful for when only using post sensor, so this distance can be the amount to move to clear extruder gears
wide violet
It is if you have a sensor after the extruder
if you don't have one, ignore it
And we generally don't recommend needing one
azure nacelle
i have two im using the wwg2 with pre and post
for tool_stn_unload measured from just above the pre extuder sensor to the nozzle i got 118
azure nacelle
It is if you have a sensor after the extruder
is it just the distance between the two
i guess i just leave it at zero
testing it
it got stuck in the toolhead again
nevermind it looks like it cut the filament and didnt pull it past the tool start sensor
wide violet
you probably need to increase your tool_stn_unload then

Please run this debugging script when not printing and post the resulting link in chat.
buoyant stump
we will hope this works today
buoyant stump
great, termbin was having issues earlier this week.
azure nacelle
Was able to get through one change but it looks like it's getting stuck on lane 4 change was from lane 2 to 4
and lane 2 to lane 3 works
lane 3 to lane 1 same error
lane 1 is getting stuck ike lane 4
buoyant stump
please be more descriptive
azure nacelle
It is getting stuck trying to respool
I have to tug the filament a little bit to get it to move
Only lanes 1 and 4 it partially retracta then I hear the motor in the box turtle spinning with no movement and I have to tug it a little so it continues to spool
ok I reset the tension knob and cut off the old filament with some gear marks and it worked once trying one more time
Got it to happen again
Something took a chunk or stretched it?
mustve been that huh lane 4-1 just worked
trying a test print now
