I print @Chase.Wichert Titan Dual Direct Drive and I want to share my progress and settings, So here S3D is used on thingiverse 1st part done Titan_Dual_X_Motor_Mount_rev1 - 0.2 - 46% - infill - no support - PLA - X-Rotate -79,75 Titan_Dual_X_idler_rev1 - 0.2 - ~46% - infill - no support - PLA - X-Rotate ...I got some eclipse shaped hole there Titan_Dual_MotorMount_Idler Bearing_Clamp_rev1 and Titan_Dual_Magents_Metric... 0.2 layer 40% infill -> almost solid Rotate: -> not sure which axis X - Clamp 90 degree Y - Magnetholder 180 degree with Raft for more bed adhesion PLA No images yet Titan_Dual_Extruder_Carriage_x2_rev2 0.2 layer 40% infill -> almost solid Rotate: Y 270 degree PLA No images yet Titan_Dual_X_Carriage_rev2 0.2 layer 10% infill -> saving weight PLA needed a raft... I think I have a problem I cannot get good 1st layers anymore.... No Images yet I did an almost finished test assembly of a titan and a Titan_Dual_Extruder_Carriage_x2_rev2 and then tryed to insert it into the Titan_Dual_X_Carriage_rev2 and is does not fit, the extruder carriage is to thick on that rail/guide thingy... What did I do wrong? I will measure the parts now.. https://goo.gl/photos/uz9XRXov5VFNUCkYA What do you think?
Make sure that you dont have to force the rods into those holes. When I did mine, apparently the holes were too small, I was overextruding and didn't know it, and it was nearly impossible to get them in and out, I ended up cracking it also, However it still works, and I ended having to drill it out with an O size drill bit, the closest I have to an 8mm which is slightly larger. But I noticed in E3D's first carriages there wasn't enough to tighten on the rods well enough, so mine still slipped. But I widened the gap for them so you had more clamping force, and I don't know if 46% is too much there is a lot of stress on those rod clamps. That looks really good. What material is that? Also I wouldn't print the carriage, extruder carriage, or the motor mount, I have quite a few changes to do to those.
I don't know S3D said about 68g, and I did not find any recommendation on this (ok did not search that much). But I think it must be quiet massive to clamp the x-rodes, or not? Oh it's PLA from Multec.de, which I bought about 1 year ago. Fun fact I did not store it in a special way, just had it laying open on the shelf for that time and the only problem I have with it is it had some diameter inconsistencies which I fixed by cutting and splicing with these nice things ebay and you can do some fun things too
The main thing is the carriage weight that makes the most difference. The lighter the carriage weight the better, the others don't matter AS much
Yes that is what I'm thinking too, and on the carriage is probably not so much stress. BTW Really nice work, thank you Since I do not print unattended (I have cats...) it will take some time to complete, looking forward on rev2.
Link doesn't work. Offer has ended. I'm interested in splicing equipment. Suddenly I get the image of cats playing and creating havoc with the motion system
Hmm yes it's ended, I had to scroll down some pages to see it. But it the blue things on the image, it's a alu.. rode with a 1.74mm hole and some alignment rings... I do not even know how to it is called in German so English must be worse That's a highly accurate drawing of the 2 peaces You sitck the 2 ends in the holes and burn them (lighter), then stick them together and press and rotate them against each other and you have spliced filament with 2 alu things in it. (after some tries) The blue PLA sample which came with the BB was a really tight fit. One of my cats goes crazy when I have some wire(filament) hanging somewhere so my fear is she will catch the filament on the BB spools and tear down the BB with it....
@Stefan, I thought that @Chase.Wichert still needs to redesign the parts because E3D V6 does not touch the bed. I am stoping my printing as I am waiting the modified ones.
