My Voron 0.1 just got EVEN FASTER! Goliath Hotend Review
HTML-код
- Опубликовано: 27 июл 2024
- Today I'm doing a quick review of my experience setting up a Goliath Hotend on my Voron 0.1, utilizing the Rapid Burner V8 mount.
Why I bought this?
0.6mm nozzles are great for printing functional parts quicker, the problem is that standard hotends do not have the flow rate to keep up with the speeds that the Voron 0 is capable of. The Goliath hotend is the ultimate fix to my flow rate issues. Capable of 100mm3 flow rates, this thing is the end game hotend!

This is all very specific knowledge that I don’t quite grasp, but watching them work is magic.
Great video, hotends are a fun topic. Hopefully I can get my hands on a similar one in the future. Cheers
my 0.1 is my modding printer lol, 90% down time 10% benchy, managed 1000mm/s at 65k accel but it need cpap cooling upgrade
😂 I can see how it can easily become a printer like that, so many great mods and community behind Voron that you can forever tinker with it. Those numbers are insane btw haha
yep, tinkering with it forever, been modding it for a year and half no on the v0, currently a bit busy with work and uni but once that is finished I should have more time to redesing the belt path to include awd with 4 neam 17 servo. Currently the main limitation is the stiffness of the tool head, since the hotend is so much longer than something like a v6 hotend from back in the day, the leaver effect is ruining inputshapper with these tiny rails even with preload, so need to redesing that and machine some mounting out of titanium to stiff it up whiles maintain the weight. The other limitation is cooling I need somehow find space to have a cpap intake hot chamber air to cool the printer parts as I mainly want to print abs on it. Majority of the trouble from modding a v0 is packaging everything into such a tiny printer, unlike the vzbots and havort they have so much more room to play with, v0, with the main benefit of lighten gantry is also it main challenge
do you have this mount for cpap and/or goliath , albo this awd is sound great if you would share it ;)
wow
incredible!
those tower flow tests are subjective and not very useful. the point at which your print starts to fail isn't the point where you start underextruding. you can have perfect looking walls while underextruding by 15%, which can be tested. you need to use CNC kitchen's method of generating blobs and weighing them to truly find the limits of your hotend per material. your approach is too basic to truly optimize your setup. and yes, the artifacts you were seeing were underextrusion despite what the subjective tests would lead you to believe. these machines aren't that complicated. don't let your bias prevent you from improving your experience.
likewise, controlling print speed with specific velocity controls is mostly obsolete. you can let autospeed combined with a max vol flow cap (found by weighing blobs) determine your speed all throughout the print, which will basically guarantee the fastest possible speed without ever underextruding. this + per feature acceleration control + conservative speeds for external and small perimeters = a printer fully optimized for speed that doesn't create shit parts.
W edit.
Try using Inner/Outer/Inner wall ordering (that's ehat it's called in orcaslicer) for better outer wall consistency (+ you get better wall tolerances too)
Thanks, I wonder if there is this option in Cura?
I’m thinking of replacing my SB to rapid burner with Goliath for my 2.4 350, how is it going 4 months later?
Still going great, i do get oozing at the hotend heatup but ive just been lazy to change my gcode at print end to retract a bit to compensate this oozing at the next project start heatup cycle.
Thank you for not supporting slice, subbed for that alone. Spread the word, this hobby was kept from us due to patents in the first place, f* patents, f* slice and f* bondtech for patenting a f* pattern, making it impossible to order the bozzle. Love your color scheme btw
bond tech didnt patent the geometry thats 3dsolex
what temps are you using ? i got on my goliath 75mm³/s for dayly printing and when i go speed printing with higer temps up to 110mm³/s 😅
on my dragon volcano with cht volcano i get 60-65mm³/s 😅
maybe your extruder Ampere is a bit to low 🤔
I usually print around 240c , 75mm3 wow, what kind of speeds does that equate to? You are correct with the extruder and it could be the issue as i havent actually bothered tweaking the extruder, i suspect its underpowered in some way. I need to research and see what people are using for the sherpa mini
I use on my Trident with a moons 10T motor 0.9A vzhextrudort CNC extruder
On printed extruder i use max 0.75A
And speeds 600mm/s at 0.25 Layers for infill or so
honestly for a goliath that flow is quite low as people are squezing 200mm^3/s out of revo's and the someone using the goliath got a flow test up to 600mm^3/s
True but most people with the Goliath have an HPAP fan/cooling system and those are around 30K RPM and also take weight off the hotend and cool the stepper motor for the extruder as well as the nozzle.
Also that's a small area, high flow rates like that need more room as printing from side to side on shay, a 230mm plate gives it much more acceleration.
