Prusa or CoreXY for Diamond hotend? Hi, I'm in the process of rebuilding my Prusa i3 to run a Diamond hotend. Following the "swinging extruder" design of my Delta, I want to keep the Bowden tubes as short as possible. The steppers would be mounted above the hotend on a horizontal 2020 extrusion and a third z-stepper would lift the assembly in sync with the hotend. The rebuild is huge and the acrylic Prusa frame might not be worth it, so I thought to build a 2020-Prusa. But I also consider " going all the way" and building/modding a CoreXY printer. Can you recommend a CoreXY kit that has all the special parts and is adaptable to fit my extruder assembly? https://reprap.org/forum/read.php?4,745186,745186#msg-745186 Tue, 21 Jul 2026 09:20:02 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?4,745186,746345#msg-746345 Re: Prusa or CoreXY for Diamond hotend? https://reprap.org/forum/read.php?4,745186,746345#msg-746345 JamesK Reprappers Tue, 07 Feb 2017 15:33:05 -0500 https://reprap.org/forum/read.php?4,745186,746099#msg-746099 Re: Prusa or CoreXY for Diamond hotend? https://reprap.org/forum/read.php?4,745186,746099#msg-746099

One thing I really didn't like about the D-Bot was it's use of plastic corners. If your going 2020, you really should have metal on metal for a corner.

Oh, I've thought they were only an add on and he was using the center hole connection method. That's what i'd do...
But at some closeups you can see a gap between the extrusions. Seems he is going the cheap way of hacksawing the extrusions without milling the ends afterwards.]]> o_lampe Reprappers Tue, 07 Feb 2017 03:10:34 -0500 https://reprap.org/forum/read.php?4,745186,745898#msg-745898 Re: Prusa or CoreXY for Diamond hotend? https://reprap.org/forum/read.php?4,745186,745898#msg-745898 PDBeal Reprappers Mon, 06 Feb 2017 11:22:34 -0500 https://reprap.org/forum/read.php?4,745186,745774#msg-745774 Re: Prusa or CoreXY for Diamond hotend? https://reprap.org/forum/read.php?4,745186,745774#msg-745774
I've also seen the G&C corexy and the D-Bot. The latter seems to be the easiest to convert to linear rails.

About the D-Bot: Would it be possible to rotate the gantry 90°, so the beam for the hotend would be shorter/lighter?]]> o_lampe Reprappers Mon, 06 Feb 2017 04:17:23 -0500 https://reprap.org/forum/read.php?4,745186,745687#msg-745687 Re: Prusa or CoreXY for Diamond hotend? https://reprap.org/forum/read.php?4,745186,745687#msg-745687
The main issue is that this printer is largely built in place. It not meant to have the E3D mount removed form the x carriage. You have to disassemble it. (blower fan and fan ducts cover mounting screw heads.)
I will be looking at updating mine to use hex head bolts, held in place in the plastic. As you can get to the Nuts easily. This would solve it.

Other than that I think it would be a good option for a diamond head]]> Dust Reprappers Sun, 05 Feb 2017 18:27:36 -0500 https://reprap.org/forum/read.php?4,745186,745615#msg-745615 Re: Prusa or CoreXY for Diamond hotend? https://reprap.org/forum/read.php?4,745186,745615#msg-745615

I also consider " going all the way" and building/modding a CoreXY printer.

you seen the hypercube on the thingiverse, its a nice design and well documented I cannablised an mendel i2 +£60 am happy with it been a great introduction, to corexy. The x axis supposed to be10 mm tubing but I just used 8 mm bar there few option in the remix section. the orginal a little short on Z at 160mm but its easy enough to extend to get 200mm. and the creator provided some well documented build log.
vid of the extended in action forgive the quality! lowers head in shame]]> jinx Reprappers Sun, 05 Feb 2017 13:12:52 -0500 https://reprap.org/forum/read.php?4,745186,745575#msg-745575 Re: Prusa or CoreXY for Diamond hotend? https://reprap.org/forum/read.php?4,745186,745575#msg-745575
DJDemonD did convert his to use linear rails, but for what I've seen on mine with the Duet controllers I don't see any ringing for what I do with the machines.]]> PDBeal Reprappers Sun, 05 Feb 2017 11:38:17 -0500 https://reprap.org/forum/read.php?4,745186,745414#msg-745414 Re: Prusa or CoreXY for Diamond hotend? https://reprap.org/forum/read.php?4,745186,745414#msg-745414 it seems the printed version has no real advantage against a Prusa? Same rods/linear bearings, but even longer belts for more ringing?!

The Alu version looks better, but I'm spoiled from my Deltas linear rails. Have you tried to convert your printers to rails instead of rollers?]]> o_lampe Reprappers Sun, 05 Feb 2017 02:53:01 -0500 https://reprap.org/forum/read.php?4,745186,745304#msg-745304 Re: Prusa or CoreXY for Diamond hotend? https://reprap.org/forum/read.php?4,745186,745304#msg-745304 Smartfriendz Smartrapcore ALU kit (primarily due to the state the kit arrived in my case with mismatched designs/parts and other people have had similar issues), but all of it's design is up on Onshape and could be easily copied and modified to fit your diamond hotend setup.

The design itself is very stable, and with a few modifications upgrading to 32-bit electronics and modifications to the rear pulleys, it works very well. It does have a belt driven Z-axis, but I've not had any issues out of mine and modifying the cantilever bed to be 180mm wide has stabalized my printbeds. I've been very happy with the 200x200 design that I've built 3 more based on the kit, and get very good results with the E3D V6 hotends and 0.15mm layer heights on a 0.4 nozzle. The ones I've modified to be a Titan E3D direct drive have been more accurate than the Wade Geared Bowden extruder I have on one of them.]]> PDBeal Reprappers Sat, 04 Feb 2017 12:26:10 -0500 https://reprap.org/forum/read.php?4,745186,745186#msg-745186 Prusa or CoreXY for Diamond hotend? https://reprap.org/forum/read.php?4,745186,745186#msg-745186 I'm in the process of rebuilding my Prusa i3 to run a Diamond hotend.
