hi all
my t500 extruder is continually jamming.
It’s not a quick and easy fix either. I have to completely disassemble the extruder and separate the sprinkler head and heat sink then bake in the oven to soften the clog and remove.
last time i broke the temp sensor wires so now i have to replace the part.
has anyone been able to do a remove and replace with third party parts?
Any one else having stability issues with this thing?
This doesn’t exactly answer your question, But from my experience with Sovol your better off getting rid of them and buying a Bambu Labs printer. You’ll never look back.
Check the nozzle for a tight fit. I had switched to an E3 generic nozzle in my original SV06 and it was clogging as you describe. It turn out that there was a space between the inside end of the nozzle and the heat break assembly. Getting the properly fitted Sovol nozzle solved this.
You may just need to tight the nozzle up more. Try reinserting the cleaned nozzle with no filament, heat the extruder up to 250C, and then tighten the nozzle further.
i wish it were that easy but i never found an affordable large format printer. even the t500 is too small. yeah i heard good things about the bambu line up. I’m pretty sure it would be costly to sell the t500 at a huge loss. but i found the issue for this failure. there is a white plastic insert between the heatsink and the drive assemble that is drilled too small. you literally have to force filament using long nose pliers and it’s a very tight fit.
but i found the issue for this failure…this time… there is a white plastic insert between the heatsink and the drive assemble that is drilled too small. you literally have to force filament using long nose pliers and it’s a very tight fit. too tight in fact. i measured .082 and i think it needs to be a tad larger like .085. not sure what caused the filament to swell but a ream will address the problem.
So about 2.1mm then. You could get a larger diameter tube (avoid the Capricorn tube, it’s great, but a tighter fit).
Or…
Extruder clogging always happens in the “HeatBreak”. So too much heat just above the nozzle. If you keep cranking up your print speed, and then keep cranking your hot end temperature, in order to prevent under-extruding, eventually you will hit the limit.

I’ve given up on this (t500) thing. not only does the extruder get clogged up it also leaks around the union, eventually encasing the bottom half of the extruder. Attempting to clean out the filament causes wires (thermocouple mainly) to get broken and forcing a heater replacement. this time though I am gonna try to seal the heater and heat block using high temp rtv- good for continuous use at 650 f (340c) continuous or 700f (370 c) for 39 min. and install a new thermocouple. If i can get the printer working again it will be used to print the voron stealth burner upgrade.
