For all AnetA8 users and other printers with a non metal frame.
I have seen many ppl who build a spoolholder for their Printer. Thats good, but do not build one that will be topmountet on your printer, or other stuff that is topmounted.
I did some tests with weights in different positions attached to the top of my printer( the part of the frame where the lcd-panel is (AnetA8)). It will effect ur print ur zeroing, pretty much everything. More weight more problems… If u wanna test it by urself just Zero ur printer, put some weight on the top of ur printer and u will see the difference, also when printing touch ur frame an feel these tiny vibrations, these are “normal” but with weight on top the vibrations maybe get worse… Also if u add something like an arm to hold a lamp or something, that arm could start to swing slightly… Tested it with normal speeds…
Acrylic frames are shit do not stress them.
I have notice this myself and I’m looking for a better spool mount. Good info.
@Jeremiah_Coley do u have a AnetA8 with this cheap spoolholder?
U can mod it easy, and it would work perfect and nearly the same like a topmounted one.
*Many people think topmounted is better because less need to pull, thats correct but it can push down/up slightly when retracting kinda movements ,the spool get a small backturn from retract and so on… In my eyes, the best way ist to use a guideroller, u will get a better effect, because the material that need to get pulled up from ur Spool is nearly the same like the amount that gets pulled down to the extruder, the fricton of the bearing is pretty much the only negativ point but…lol… and that u should place that holder in front of ur printer or behind but always in the middle. The behind version would need a longer part then the front
U would need 3 bearings (2of them with the diameter of the studding ur spoolholder sits on) One screw two nuts.
Other parts u would print. an arm from spoolholder to the highest point of ur extruder +~50mm, stable enough that it cant bend or something. the guideroller (not to small diameter) with a protection that the filament always gets guided but can move free and fits on ur bearing, and some small spacer to position ur guideroller bearring. Also some “spacer” for positioning and guiding ur spool.
If u want a fast hand drawed sketch just ask.
I wanted to build one but then i recognised i dont need it, because i just place my normal AnetA8 spoolholder in front of my printer in the middle, also using a tissue:joy:
that protects my spool from “spinning” and my filament from getting lose on the spool. could not see any problems. only added 2bearings for smoother feeding.
