Re: Under extrusion after upgrade to bowden extruder - 11 years ago
So.. while the parts I ordered Arrive I have a small update.. i have read about the Canola Oil use for the e3d V6 and I must confess even when i read before I did not want to use ( cause it should not be needed, and also. this could affect adherence and well.. many other reasons) however having no other option, i used some and the results have been as expected. no more under extrusion, but also iby gabrielcr78 - General
Re: Under extrusion after upgrade to bowden extruder - 11 years ago
hello IMBoring25 et all, Certainly the main topic issue is not yet resolved... my weekend update... i went and purchased a thermometer (did not find anything that could help me to measure more than 120 °C without melting but within those ranks i found that the thermistors i have are not the most exact according to the table I've selected in marlin... (which is supposedly the one for them) so I'by gabrielcr78 - General
Re: Under extrusion after upgrade to bowden extruder - 11 years ago
as a matter of fact i'm heading out to buy one right now.. also already ordered some replacement thermistors from e3d and and two .4 mm nozzles (brass and steal) ... but that will take a few weeks to arrive to my house here in Costa Rica.. so better to find alternatives.. i'l do the tests and let u knowby gabrielcr78 - General
Re: Under extrusion after upgrade to bowden extruder - 11 years ago
I agree Mark, I also get the same behavior here.. , the section of the filament that is in the "transit zone" should not be that swelled... that means during reatraction it cannot move back into the PTFE tube, and eventually not even move fwd into the melting zone... in my case it might have to do with the fan duct i've printed to mount the cooling fans on it... i'm dissasembling everything anby gabrielcr78 - General
Re: Under extrusion after upgrade to bowden extruder - 11 years ago
Quotethetazzbot I was thinking my stepper motor was too wimpy for this, but if you're using a geared extruder and having similar issues, I'm not so sure. I have managed to print I'm not using a geared extruder, i'm using same config as you are: bowden extruder with an MK8 see pics in my last post... I'm almost sure this problem is actually something happening inside the hotend.. I think filamby gabrielcr78 - General
Re: Under extrusion after upgrade to bowden extruder - 11 years ago
Hello sdavi, attaching pictures of the feeding mechanism, i tried to reduce any resistance from he spool bu using bearings and also placed the spool in a position very close to the input of the filament in the Extruder.... spool location spool bearings now i have a question for all the forum, which hit my mind.. has any of you used the 100K ohm NTC 3950 thermistor from aliexpress on a hotend? iby gabrielcr78 - General
Re: Under extrusion after upgrade to bowden extruder - 11 years ago
that's right tthetazzbot, one time I failed to connect the heatsink fan, i realized soon enought so i removed the PTFE tube and it was ruined, luckyly I learned my lesson with no more damage than that. but the thing is that i printed several stuff with this e3d v6 in pretty good quality before swaping to this new extruder... that's the reason it thought it was related to that change.. maybe it'sby gabrielcr78 - General
Re: Under extrusion after upgrade to bowden extruder - 11 years ago
Alright Andrew, So just for the kicks, I decided to test once again to share the paramethers I'm using: this time, I lowered the current of the motor to 1.3 A (72% of the operating current 1.8A), and increased th tension of the spring as much as possible. Also pre.heated the filament hotend before inserting the filament. retraction set to 3 mm at 40 mm/s and print speed 40 mm/s (first layer 20by gabrielcr78 - General
Re: Under extrusion after upgrade to bowden extruder - 11 years ago
QuoteAndrewBCN Unfortunately the E3D V6 has acquired a bad reputation for jamming as it warms up during print (note that I have no idea whether this reputation is deserved or not, as I do not own a genuine E3D hotend, V5 or V6). Could you post a couple of pictures of your print head and extruder setup? Are you providing proper cooling for the E3D aluminum fins? Have you tried another brand of filby gabrielcr78 - General
Re: Under extrusion after upgrade to bowden extruder - 11 years ago
Quotedc42 Quotegabrielcr78 1. Are you using bowden configuration as well, and if so, using an MK8 gear too? 2. Do you have your DRV8825 an if so, configured for 1/32 microsteps on the extruder motor too? 1. I am using a Bowden extruder, with the RepRap mini geared extruder that I received with my Mini Kossel kit from Think3DPrint3D. This is what it looks like: ...

Re: Under extrusion after upgrade to bowden extruder - 11 years ago
Thanks for your answer dc42, 1. Yes it's genuine e3d V6. Bought it and received directly from e3d-online.com 2. The nozzle reads stable temperatures just like it did when i had it mounted in direct extruder. Quick questions for you: 1. Are you using bowden configuration as well, and if so, using an MK8 gear too? 2. Do you have your DRV8825 an if so, configured for 1/32 microsteps on the extrudeby gabrielcr78 - General
Under extrusion after upgrade to bowden extruder - 11 years ago
Hello All, And many thanks in advance for any help you can provide on this topic as I'm fairly new at 3d printing. So let me give you some details about the configuration of the printer I've assembled: -Electronics: Ramps 1.4 + Arduino Mega 2560 running Marlin 1.0.2 -Motors: 5x 17HS840 stepper motors (they hold a max operating current of 1.8A) -Motor drivers: DRV8825 configured at 1/32 micrby gabrielcr78 - General
