Ok... I can see your Auto Generated GCode has not been corrected to match the proper timing. Please regenerate the GCode... I've updated it to make it better match the timing. Also, my documentation needs to improve on this process... I'm going to record a video this weekend to show how it's done.
In summary, there are two ways to get accurate button press timing.
The first way is to use the Autogenerated GCode and edit the press times to make the G4 P{time} values to match exactly what your printer is doing. This is the simplest to understand... and you can actually do it by trial and error. The button pulses are about .5 seconds apart...so you can set the times for the buttons to match that... for example, the gcode now uses P500 for 1/2 second for the first extruder, P1000 for the second, P1500 for the third and P2000 for the fourth. That might be too long or too short for your printer. So you can adjust them up or down... for example, if it's too short, you might change them to P600, P1200, P1800 and P2400. They're all always multiples of the first value, however. So a 7 pulse would be P4200 or 4.2 seconds, for example.
The second way is to allow the system to time the pulses. The 15 pulse command allows for that.
The idea is that you're supposed to use the start gcode and the 15 pulse command to program exactly how long it should be waiting. Please not the 15 pulse timing requirement... it's exactly the same process as above, where you enter the time it takes to do the 15 pulses... but that is the only point you need to do it. All the rest will automatically happen.
So... in your case, you might have a block of commands that look like this in your start GCode after you home it:
; button press calibration - place after your homing sequence in the start gcode
G0 X99.5 Y199 F2000 ; go to the holding location
G0 Y202 ; hit the button
G4 P7000 ; waits long enough to trigger the 15 pulses <--- Make sure you tune this actually match your 15 pulse time! (Count the pulses as it presses the button... too many pulses, shorten the time... too few, increase the time) G0 Y199; back off the button G4 S2 ; just wait a second for it to respond - should vibrate 3 times
; ok, here is where we program your P100 timing the rest of the code uses
G0 Y202 ; hit the button G4 P100 ; this matches your #1 extruder command
G0 Y199; back off the button G4 S2 ; this waits for 2 seconds... it should vibrate once here
G0 Y202 ; hit the button a second time G4 P200 ; wait twice as long as #1 command... (same as #2... but the unit factors out any time delays due to motion.)
G0 Y199; back off the button G4 S2 ; this waits for 2 seconds... again, it will vibrate in response
; this block should home the unit - if it doesn't, adjust the P100 above until it does G0 Y202 ; hit the button G4 P700 ; this is 7X the P100 value... which is a homing press G0 Y199; let off the button G4 S2 ; wait 2 second for it to happen ; ok - this is the end of the calibration code
What this code does is give it two example button press commands... a 1 pulse and a 2 pulse command. The unit then calculates exactly how long it takes for each pulse to occur and maps the internal clock to exactly what your printer is doing.
