Lgx lite and rapido 2 constantly clogging.

After a print goes for a couple of hours sometimes 10 hours sometimes longer. there will be an clog and i have no idea why it happens.

Just some information i have a 0.4 nozzle. i print at 200 C 0.6 0.6 line width 0.28 layer height

where is it clogging in the rapido? The fact it takes a while suggests heat creep - is the heatbreak fan pointed in the correct direction? How hot is the area around your hotend? Is your printer enclosed. What filament are you printing?

im printing pla. the heatbreak fan is pointed at the correct position with the label Towards the heatbreak. the area around my hotend is ? normal i think. its not enclosed I also switched nozzles I cleaned it out the heat break seems to be clear and then with a new print it happens again. First it happened after a day and a half and now it happend after a couple of hours already.

what are your retraction settings? 200C seems really low for PLA, have you used a thermometer to double check the thermistor?

No i havent i dont have that stuff just laying around could my rapido 2 be broken or something ?

are you sure the nozzle is clogging? As @blacksmithforlife 🇺🇸 indicated, 200C seems quite low for PLA. What brand of filament? Have you verified the diameter of the filament's consistency? I had a few spools with 0.15mm variance (1.9mm) which led to it not feeding through.

I have sunlu and ive been running it for years on other printers without issues. 200c is quite normal for pla right ? I mean i can up it see what happens ill put it at 210

210-215 tends to be where my PLA profiles are set, but it varies by filament

Printers which are likely much slower than a vcore

yeah, that is very low at the speeds and feeds of a vcore3

Makes sense 215 it is

But, you still haven't answered what your retraction length/speed is. You could be pulling too much into the heatbreak

0.4 and 40 mm

blacksmithforlife•10mo ago
yeah that probably isn't it. What speeds are you printing at?

350 mm/s Upping the temp to 215 seemed to help. Im running a shorter print now and see if problems will arise then i will go to bigger prints

yeah the faster you print, the more you need to cranky up the heat. Plastic doesn't absorb heat well, so when you are printing that fast you need to increase the hotend temp so the plastic gets molten in time
