I am building new printer,and i am in dilemma if bondtech extruder is worth its money. Printer will be big,lasercut steel frame,with the best components available. I had searched bondtech videos,but none is with high speed
. Anyone?
when I read “the best components available” and extruder, automatically @SVEN_KRAUSE comes to my mind 
The Printrbot gear head is similar in design to the bond tech. I released my files open source a couple days before he showed his. Printed files are on youmagine. No geared stepper used on ours so it’s faster. Paired with a Ubis 13S, it can go very fast. I run a 1mm tip at 80mm/sec but with acceleration on the Printrbot Big-E and it plows through the filament. .4mm tip is stock size. It’s a far cheaper setup than a bond tech
All I can say is ask Bondtech owners if the Bondtech extruder is worth the price. Every Bondtech user I have ever asked loves theirs. I know it is worth it to me it is, so much so that I have one or two on all four of my printers.
Best price vs best value are two different things to me. In the almost two years since I owned mine I have never once jammed a Bondtech. I have used many many extruders before the Bondtech. In my experience nothing else I have used matches it.
Just my 2cents.
I use http://www.thingiverse.com/thing:979113 Saintflint Extruder, it is great, uses either mk7 or mk8 gears - however it is bowden extruder if you are intereste you can give a try.
I’m in both camps…I bought a bond tech because I was tired of trying to figure out why my Greg Wades extruder kept failing…after doing that, I had some time to putter and bout a #saintflint and both have worked great. I think the secret is: the filament needs more than one grip path, whether that’s using a gear to push the plastic from both sides, or run the plastic past the same gear twice, both work better than a single side+pinch wheel.
If you see my previous posts you will see that i allready have saihntflint. I really dont like bowden.
New printer will have all nema23’s,hiwin rails,lasercut metal frame,a lot of power etc.
Nema23 counts the Printrbot gear head extruder out… It uses a nema17… But not sure you meant that the extruder is going to be nema23.
Is anyone with a bond tech up for a free gear head to try “head to head”? I’d expect the geared stepper to win a bench test but I haven’t had any jams w it. I’m wondering how it compares for the price ??
First 4 willing to publish results get the freebie. I’ll ship it w a Ubis 13S, too. Just want the truth- don’t go easy on me for the free gift. I’ve considered a geared stepper version and wonder if it’s worth the trouble. I haven’t needed it yet. My Big-E is the best test I have for demanding flow and it has to drag the filament out of a 5kg roll too, so it’s a pretty good test I think

@Brook_Drumm what results are you looking for? I just began my review of the new QR Bondtech, and will be posting an article in the coming weeks. If you don’t have an issue of your extruder being tested on something other than a printrbot, I’d be happy to add it to the mix.
Also, this is little off-topic, but this isn’t exactly a “dilemma”. A dilemma is a choice between 2 equally bad things. Your choice is between A) a fantastic extruder (bondtech), or B) a cheaper extruder.
Remember, you cry once when you pay for quality. You cry twice when you pay for crap.
@Taylor_Landry no expectations. Any boy should work. Let me know.
Sure. Send it on down to MatterHackers. Put it to my attention. I’ve got a Prusa running a smoothie and a volcano that can give extruders a nice run for their money.
I’d sign up @Brook_Drumm , but both printers are Bowdens.
@Brook_Drumm
not extruder, only x,y and Z axis.
my goal is to achieve rock solid, and heavy lasercust frame(60-80 kg). This time i will try to avoid vibrations on linear rails, and use hiwin rails.
My goal is to test what are maximum speeds that we can achieve with 3d printer.
i will instal gt2 10 mm wide belts to avoid streching, and drive with corexy to minimize moving mass.
electronics will be toshiba external drivers, they can deliver a lot power compared to tiny onboard stepper drivers.
only left thing is to choose right extruder and hotend.
this will be very interesting experiment
