Right now I have a a heatsink fan on full. I only heat my hotend to 240 for PETG and it works fine. I have a 2nd thermistor on the heatsink itself and it reads 100deg C. Still hot but not that bad. The heatsink shroud is made of ABS so well below the metling point of ABS.

Hm... My heatsink is about 45C, I think. Because I can easily touch it by hand and it's definitely colder than heat-bed @ 60C. And I do not have fan shroud (I use stock mount way).Quote

Interesting. Maybe it's cold in your room?

I see all the comments and yes. I think the only reason my heastink E3d combo works is that my room is cold. Its the basement and its around 65 deg.

But I meant GrAndAG's room. ;-) His heatsink seems to be much colder than yours?

Does anyone know which file I should use when printing a replacement effector?
Has anyone printed one that fits the hotend that Sintron provided?

... i should lower the delta radius, but we have it as an equation in the sintron marlin firmware. so i got stuck at that, i don't know what to modify next.

i tried manual calibration, using this method. I adjusted the endstops offset fot near the pillars positions. Those 3 positions where good, then when i checked the center, it was lower than it should. according to the vid, i should lower the delta radius, but we have it as an equation in the sintron marlin firmware. so i got stuck at that, i don't know what to modify next.
Is there a better method for calibration?

After adjusting smooth rod offset you have to re-calibrate end-stop offsets. Because actually the adjustment does not directly lower/upper effector in the center, but more likely uppers/lowers positions near towers.Quote

I played with the smooth rod offset, but i'm not getting it right. i measured 161.5mm. this value doesnt't work. also tried 159 to 175. no good. any suggestions?

After adjusting smooth rod offset you have to re-calibrate end-stop offsets. Because actually the adjustment does not directly lower/upper effector in the center, but more likely uppers/lowers positions near towers.
So, actually, the very first calibration process is cyclic: adjusting end-stops - adjusting smooth rod offset - re-adjusting end-stops - re-adjusting smooth rod offset - and so on. Unless you have all 4 offsets (3 towers and center) the same. After that adjust total height to tune 0 height.
If you heed to recalibrate in future (i.e. because of re-leveling of bed), the adjusting of end-stops will be enough.

Now i'm having some issues printing a first test. The printhead moves, but the PLA comes out too slow, no enough flow for the printing speed.
Also, the fan doesn't spin. Just makes a buzzing sound. Anyone else had problems with the fan?
