extruder motor location - whats verdict? I have heard good and bad things about mounting the extruder motor (ie direct drive) vs mounting it separately...the most notable one I guess is with direct drive the X motor has to carry the weight of the extruder motor.....but whats the final on this? is one better than the other or doesnt really make dfiff? https://reprap.org/forum/read.php?397,835984,835984#msg-835984 Fri, 17 Apr 2026 11:01:24 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?397,835984,836110#msg-836110 Re: extruder motor location - whats verdict? https://reprap.org/forum/read.php?397,835984,836110#msg-836110
Being a glutton for self punishment I'm trying to design my own cost effective remote drive solution. These rarely end up actually being cost effective for me compared to existing solutions but I learn a lot more in the process.]]> obelisk79 CoreXY Machines Sat, 13 Oct 2018 10:44:45 -0400 https://reprap.org/forum/read.php?397,835984,836094#msg-836094 Re: extruder motor location - whats verdict? https://reprap.org/forum/read.php?397,835984,836094#msg-836094 Gimballed Flystruder
This is available as an accessory, as part of the ongoing KickStarter campaign
Zatsit on Kickstarter
I would be curious to see this accessory adapted for contexts other than a delta printer: indeed, the reception device consists of two holes, and two spherical magnets. It is very easy to adapt.]]> M_Xeno CoreXY Machines Sat, 13 Oct 2018 06:45:55 -0400 https://reprap.org/forum/read.php?397,835984,836069#msg-836069 Re: extruder motor location - whats verdict? https://reprap.org/forum/read.php?397,835984,836069#msg-836069 Here's a video]]> o_lampe CoreXY Machines Sat, 13 Oct 2018 01:45:28 -0400 https://reprap.org/forum/read.php?397,835984,836061#msg-836061 Re: extruder motor location - whats verdict? https://reprap.org/forum/read.php?397,835984,836061#msg-836061 obelisk79 CoreXY Machines Fri, 12 Oct 2018 17:08:44 -0400 https://reprap.org/forum/read.php?397,835984,836057#msg-836057 Re: extruder motor location - whats verdict? https://reprap.org/forum/read.php?397,835984,836057#msg-836057 somei3deas.wordpress.com].

There are pros/cons to both direct drive and bowden drive extruders (with the proper setup both configurations can yield good results). I tend to lean more towards remotely driven or bowden setups. I'm getting ready to prototype my own remote-direct drive extruder concept using a flexible drive shaft.

Some solutions you could look into:
Flex3Drive
Zesty Nimble
E3D Titan Aero

Or I recently found this interesting solution here:

Also this simple DIY:

^Note however, that this particular solution probably doesn't have enough of a gear ratio to compensate for torsional deflection of the titanium wire which would negatively affect print results.]]> obelisk79 CoreXY Machines Fri, 12 Oct 2018 12:27:33 -0400 https://reprap.org/forum/read.php?397,835984,836034#msg-836034 Re: extruder motor location - whats verdict? https://reprap.org/forum/read.php?397,835984,836034#msg-836034

A well made flying extruder is probably 'best of both worlds'
A short Bowden tube won't cause oozing and the weight of the extrudermotor is supported by the gimbal.
You only risk resonance between gimbal and hotend/effector at certain speeds, but you can avoid it with propper slicer settings.
( The effect shows up mainly during infill, so it might be not critical )

I've not seen a flying extruder on a Core-XY printer before. Do you have any links to examples?]]> obelisk79 CoreXY Machines Fri, 12 Oct 2018 12:22:32 -0400 https://reprap.org/forum/read.php?397,835984,835998#msg-835998 Re: extruder motor location - whats verdict? https://reprap.org/forum/read.php?397,835984,835998#msg-835998 flying extruder is probably 'best of both worlds'
