+1  I definitely agree with grob.  All your work has certainly paid off.

i only wish I could have achieved this quality while I was building this:

Would have saved a tonne of dremel work tongue

A year and a half of chasing issues- the new hotend solved 90% of the inconsistency ( ther was defenitely a deformation probably due to me running it into the glass bed).  The intermittent Z banding remained despite the brand new Z stepper and lead- for the FIRST time I adjusted the voltage (it was only off by a MINUSCULE amount) well... you be the judge.

Couldn't be happier right now.

Does anyone know a tidy way to cancel a running 'wait for temp' or pause command?

I had to extend the value quite a bit- truly trying to make the likelihood of baked filament as low as possible.  I think this should help plenty.  It cannot hurt!

My code:
G28 X0 Y0  ; home X axis and y axis
M104 S0 ; kill extruder temperature
M140 S0 ; kill bed temperature
M106 S255 ; turn fan on full
G4 P300000 ; wait 300 seconds
M106 S0 ; turn fan off
M84 ; disable motors

Thanks again!

Cheers

The M106 works perfectly so if the delay works- this is perfect.  Added for my next print.

Thanks!

M106 S255 ; turn fan on full
G4 P5000 ; wait 5 seconds
M106 S0 ; turn fan off

No guarantees, untested. smile

I kicked the fan on high and observed the cooling time to get below 100 degrees- just a handful of seconds once the heater is off.

Any thoughts how I could add a G code to the end (or other method) which would turn the fan on high to cool the extruder fast?

Thanks!
