I wrote a similar post but it didn't show up - sorry if it's a duplicate
ok please tell me if i am thinking correctly
we are talking about mk3 soft 3.1
after connecting the power: (correct me if I'm wrong)
1. choose impulse 1, 2, 3 or 4 (release)
2. hold for 2-3 seconds to enter filament loading mode (release)
3. hold x seconds until the filament is one inch before the green connector.
4. start printing (the rest is done by g-code from the print file)
and now I'm talking about the config file that Bill posted in the case for bamboo p1p
-------------------------------------------------
start G-code
- reset 7 pulses,
- loads T0 - 1 pulse, (but does not move the filament in any direction, the filament is still 1 inch before the green one)
chenge filament g-code (generally speaking)
- we cut the current filament
- choose which one is to be loaded T0 - T3
- we put out the old color (which is not there - filament is still 1 inch before the green one !!!)
- load a new color
- we print
end g-code
- we cut the current filament
- unload and home - 6 pulses
-------------------------------------------------
some facts (correct me if I'm wrong)
- always selecting pulse 1 to 4 - the first long press unloads the second loads the filament.
- reset 5 pulses - will also work as above
- a reset of 6 pulses will discharge the filament only as much as in mode 2, unless for mode 3 I can use a long press with the time needed to discharge for 1 inch - but does it make sense since the next print will again want to unload the old color first (old Tx )
- reset 7 pulses - does nothing
-------------------------------------------------
which of the resets unlocks the chameleon gear to move the filament freely?
Well, in looking at your comments, it looks like you're in Mode 3, which won't move the filament until you press the button again. So, your start gcode needs a second button press to actually move the filament. Likewise with your Tool Change GCode.
Mode 2 will always move the filament by unloading the active filament 10" and loading the new filament 11", with the extruder turning on for that last 1" so it can assist the loading of the filament into the extruder's drive gears.
In your "some facts", you have a few wrong.
Always unloads (if loaded) the active filament, and loads the new filament... but only in Mode 2... in Mode 3, you need to press the button for each of the additional actions for as long as you want them to happen.
5 Pulses always Homes and Automatically Loads T0 10" in Mode 2, or loads for as long as the 2nd button press is held in Mode 3.
Your description of 6 is correct... it unloads the active filament and homes to T0. Some prints do not start on the last color used... so we always use this in the end gcode to reset it.
7 pulses actually homes the the unit back to T0 regardless of mode.
It seems that some of your descriptions of what is happening are in Mode 2 and some are in Mode 3. Just remember this... Mode 3 will never move the filament unless you're pressing the button... so if you're expecting it to move it, you need to press the button. It will also only move the next phase of the command (for example, unload then load) without a second press. And will only move the filament for as long as you holding the switch.
