Ya the build manual is a bit messy. Assembled means not mounted but in step 20. you have to mount it though this is for the old dual or pro setup...
I think you are supposed to skip step 19 because when you get there you should think "I have no single direct drive, so skip, same for step 20, you have no dual direct drive and go straight to step 21. There is also the steps included to assemble the hotends... IMHO the guide needs an overhaul for better navigation, at the moment it is very based on that a user knows what he has and wants to build... A note that there are other possibilities where needed for example at the first topic to assemble the print head would help to guide the user to the right direction....
It's important to get the right length as it may rise up leaving a void at the bottom that, on retraction, will drag melted filament into it and cause a jam. It will fit if you are using stock parts.
Agreed. 83mm PTFE fit just fine on my BB Dual Hybrid Titan setup. I'd be concerned that a 72mm PTFE is far too short and likely to cause issues.
Ok anyway you can remove the Titan Mount, thing which is monuted with 2 M4 screws and assamle the Titan outside of the BigBox. Then put it back and then PTFE Tube should easiely slide in the Extruder. Tighten the 2 M4 screws and continue.
My flash is v1.1.0 RC4, I should upgrade this to RC6 for the Hybrid, correct? Edit: Right now I'm not getting any temperatures from the hotends and a MINTEMP error on the bed, but maybe I have wiring problems or RUMBA config issues?
RC4... is this a new official BigBox Firmware, I did not notice a Release. If this is a Stock Marlin you have to do some modifications to pin assignment. Or use one of Alex9779s RC6 Builds I can confirm that BigBox/Dual/RC-Titan-Hybrid-MBL is working fine, I did not run into any issues yet.
OK. I will try again. The top of my tube does fill the void completely. My problem is on the otherside of the tube. Getting the tube to seat properly in the hot end. I notice on my 2nd hotend the tube slides in freely but in the hotend I used on the titan it doesn't slide in easily. I have tried multiple cuts of tubing and I have the same issue.
Check that you have not distorted the heat break, as that will restrict the path. Also, remove the Bowden clip to check as this may be closing up but don't forget to replace it!
...the metal gasket is what I'm really wondering about. I figured the printed part was for a 1.0 system and included by mistake.
Ahhh ok, you said "extra parts" so I thought you meant both... I remember someone trying to fit that old one to the new carriage, just wanted to prevent you from making this error...
I don't remember seeing that in the build instructions or did we get a free "Astrosyn damper" mentioned in (14) Y-Axis Motor Mount?
It is not "free" it is now part of the BB kit... The drawing unfortunately does not show the dampener, the photo has it but not obvious as it is somehow hidden between the motor and the mount. But you can see that the motor does not touch the mount, there has to be something between. That is the dampener...
...and I always rely on the mechanical drawings and only look at photos of the drawings are missing. Easy enough to put it on tomorrow while I'm waiting on my replacement bed.
