I've finally finished installing e3d Titan and v6 hotend, they work beautifully with Cura. While I was trying to change filament in mid print with pause command from LCD controller, the Z stepper would drop after maybe 30 seconds. It won't come back up after resume printing command.
It must be a firmware setting or something, but I couldn't find it in configuration.h. Any idea where to look? BTW, my M2 is from 2012 with RAMbo v1.2g on modified firmware based on http://makergear.wikidot.com/m2-lcd-panel. I believe it's a Marlin 1.1.x
Z stepper drops during pause
Re: Z stepper drops during pause
When the firmware turns off the power to the stepper drivers?
If so, look in Configuration_adv.h for DEFAULT_STEPPER_DEACTIVE_TIME and tune for best picture.
Re: Z stepper drops during pause
DEFAULT_STEPPER_DEACTIVE_TIME is not found in my configuration.h. Marlin 1.1.x is too old?
Re: Z stepper drops during pause
Marlin has two configuration files:
- Configuration.h - "basic settings"
- Configuration_adv.h - "advanced settings"

I guess a new pair of glasses is in order for me . Thanks Ed!
BTW, currently the nozzle stays at where it was paused. I've seen video that the nozzle moves to the far left when pause and then moves back in place when resumes printing. Do you know where to find such parameters?
Re: Z stepper drops during pause
Dunno, because I've avoided LCDs and mid-print tweakage, but I think Marlin runs specific external routines when such events occur.
Searching the doc for keywords like "custom G-Code" and maybe even "pause" might be productive; matching the doc to the specific Marlin version you have is just the first part of the challenge.

I do avoid it too, but sometimes over confident causes a four hours job runs out filament at 90% completion lol.ednisley wrote: ↑Mon Jul 13, 2020 3:15 pmDunno, because I've avoided LCDs and mid-print tweakage, but I think Marlin runs specific external routines when such events occur.

For those who are interested in pause nozzle position, https://www.thingiverse.com/groups/tron ... opic:31421 says the parameters are in configuration_adv. But it not in my Marlin 1.1.x. No problems, at least I can change filament without Z stepper drops on me. Thanks again Ed.
