My 3D printer needs rest and sleep time after prolonged or multiple printing sessions

Hello everyone,

My SV06ACE prints perfect parts with the correct profile using foaming LW-PLA, even larger ones and those that take over 18 hours to print.

However, if I try to print another part after such a longer print, or after two or three shorter prints, I always get several layers with insufficient material, resulting in an unstable object. If I then turn the printer off and let it rest for a few hours, it prints perfectly again. Simply turning it off and on again after a few minutes doesn’t help at all; it actually needs to rest for a longer period, ideally overnight. This mainly affects prints with LW-PLA.

Have any of you experienced this phenomenon with your printers, or do you have any idea what the cause might be?

Best regards,

Klaus


Hey,
It might just be a tired printer that needs a break :joy:
Seriously, I’ve never heard of a problem like that.
Try cleaning your nozzle between prints.

Hello,

I’ve tried a few things, but they haven’t really helped. I’ve noticed that sometimes the filament feed stops for about a second during printing and only starts moving again after that. I think the filament softens from the heat before it even reaches the nozzle and then isn’t fed properly. Since it only happens rarely, doesn’t occur after the printer has been idle for a while, and only with LW-PLA, I’ll just accept it for now. Maybe I’ll get a new and better printer eventually.

Best regards,
Klaus

It sounds like a clogged nozzle.
I recommend cleaning it between prints.
Heat it to 250° and fedd the filament through the nozzle.

I took a closer look at this during my last few prints. As long as the “Toolhead Temp” stays between 45–47°C or lower, it works perfectly with LW-PLA. Problems arise when the “Toolhead Temp” reaches or exceeds 50°C. The toolhead fan continues to run after printing and shuts off at around 50°C, at which point the LW-PLA is likely still somewhat soft (according to the AI, LW-PLA softens at 50°C and above) and therefore is no longer properly extruded by the extruder during an immediately subsequent print.

Hi,

Residual heat seems to have caused this for me in the past but as you say only on very parge prints. I have not tried cooling the printer/enclosure down by using an air conditioner yet though… Theory yet to be proven. :wink:
