working on upgrading my trinus right now. all axis are on linear drive shafts so it produces excelent quality. but it can't go fast. The biggest issue is the hotend, which they claimed was going to be all metal, but it is not. It is a very compact extruder with a PTFE lining in the throat tube down to the nozzle.
I'm looking at pulling the Bondtech QR Universal off my N2. The question therefore became, do i go bowden or Direct. I started looking up some information on it and ran into a thread. hence why I am making this post here.
Be sure to use a good hotend that is well known to work with a Bowden extruder (j-head from hotends.com work well for Tantillus). Be sure to use a Bowden tube that is large enough that is offers little to no friction (1/8" for 3mm as 1/8" is 3.15mm) and be sure to check your filament goes through the tube as tubing is not made to have the inside diameter perfect and could have tight spots even if rated at 3.15mm. You will need to re-learn a bit since Bowdens require faster travel speeds, longer retracts and the most important is faster retracts.
Last thing is if your machine has a moving bed then you will still get ripples unless you are able to make it a lot lighter.
This is the information that made me wonder. The hybrid style seems to have a major issue if the bowden requires faster travel speeds. I only played with it a little bit due to the wipe wall issues. those may be fixed now. I am hoping that the new dual extruder martin is working on works out. The other option I could think of is to convert both extruders to bowden and get maximum head weight reduction. the extruder would be replaced with quick connects to attach the PTFE tubing. new profiles would need to be calibrated for pure bowden printing.
back to the trinus, this thing just has problems. people want to print high temperature materials with a printer not designed to print high temperature materials. Kodama is a 6 man operation (spread out a crossed the world, at least one IT is based in Japan) that is reselling Panowin's F1 printer as the trinus. Kodama doesn't have any access to hardware or software either. the PSU that came with it does not meet the needs of the printer. I'm working on that solution right now for mine be using a 12V 30A 360W Universal Regulated Switching Power Supply for 3D Printer and a couple of MOSFETs to provide the power for the hotbed and extruder of secondary 12v rails.
If I want to upgrade the hotend, I need to upgrade the motion controller due to the closed nature of the motion controller that comes with it. Since I want this thing to print the best i can, i am looking at Panucatt's Azteeg X5 GT 32bit Motion Controller, with all the parts for it, it is a good sized chunk investment.
I'm not sure what exactly is compatible with the bondtech QR universal. the E3D-v6 looks like one option but I'd like to also know what else there is. One of my biggest issues will be making the mount for the bondtech, to get it aligned in the same spot as the current extruder.
