Hmmm I see no difference in using a bowden adaptor or just a tight hole where the tube runs through just like it does now on the lower part...
This si true. It will leave a longer PFTE tube also. Otherwise we should lookout bringing the hot ends higher. I have all pieces for a titan change now, and I will have a look as well.
Bringing the hotends higher is limited by the travel range of the Z axis... But sure, if there is room why not... I really see not much difference in an extended straight guided bowden tube from the Titan to the hotend of about 10mm, I have to measure how much is needed to get the gear outa range of the case. Sure the tube should be as short as possible because the filament is not completely tight in the tube, could not be anyways, it has to move, and that little play allow the filament to move slightly to the sides when pushed into the hotend. This results in a decreased length at the end of the tube so your extrusion can be different. And the longer the tube the more of that little play adds to the missing length at the end...
I passed the motor wire up the back spine and then through the small circular hole between the two upper motor mounts.
Thanks. I am now also adding a spacer element between the titan and the bottom carriage to raise the extruder. Anybody else here having problem attaching the sensor box? The original design seems to large.
That's a nice idea, just model the shape of the buttom surface of the top part and make a part of it, then the whole top part comes up a bit, just need two longer M4 screw, no problem, and the longer bowden tube... Did you figure out you how much we have to lift it?
@Greg Holloway what are the cut-out dimensions i.e. length, depth and offset from rear, as I will do this before assembly.
I am making it 10mm with some margin and printing in nylon to use it also as a dampener like for the bowden one. UPDATE: I have decided tor design the mount to reuse the existing screws. Let's see how it ends up.
I made a short weight comparison, I slice at 0.2mm, 0.4 nozzle, 3 outlines, 25% infill: original: 35g my mod for velcro strips and lower cable bracket shortened: 33g lifting the whole bottom surface: 46g lifting only Titan: 38g So I have 3g more to move than if using the original design... No dealing with cutting Perspex, no searching for some who can do it. No risk that it may look ugly without being able to get a replacement part at the moment... If someone else wants it, I can do the mod for normal zip ties too then it will be approximately puls 5g compared to original, but I can recommend the shorted lower cable bracket. That way the left hotend cabling goes straight down touching the lower part and no edge...
So you didn't contact E3D to return your order? That's the great thing of OpenSource. There are endless possibilities to mod...
Alex do you have to have a differnt stepper or will the old ones work? I ordered mine state side and didn't realize the steppers were differnt. I have also been away from home so I haven't been able to get my Titans ready, just want to know if I have to order them.
