ok i made a hotend holder for e3d hotend
kindly review it and send me your feedback (i am a total noob in 3d modeling)

Already told you in a private message that I don't own an E3D hotend for this printer.

I don't even own a "Smartrapcore" anymore. My design is not compatible with the Smartrapcore anyway.

Need to redesign the belt clamps or the whole X carriage.

Belt tensioning is done via the idlers.

I'm not looking to gain print volume with this printer.

The Z axis seems to work fine, no visible Z wobble effect / banding.

No, flanged bearings F624ZZ. You could replace yours with F608ZZ + a big washer and get rid of those printed sleeves.

Have you done this on your smartrapcore? I tried it and the f608zz bearings were not wide enough for the belts to ride nicely on even with washers, and the belts rubbed on the x carriage.

I'd say you want a larger bearing both in terms of outside diameter and width.]]> DjDemonD Smart_Rap Wed, 27 Apr 2016 10:27:20 -0400 https://reprap.org/forum/read.php?344,602514,657406#msg-657406 Re: Custom Smartrapcore ALU https://reprap.org/forum/read.php?344,602514,657406#msg-657406

The parts need adjustments because the belts are really close to the XY parts and may rub at the home and the end of the x axis. Another thing that I dont like is the smoothrod fixing method for the X axis.

I ordered some T-slot wheels to convert it and use the extra space to mount 2 cooling fans on the sides of the hotend + direct drive extruder.

This is my version of the Smartrapcore Alu

Parts used for this build:

- TR8x8 leadscrew with anti backlash nut
- flexible coupling
- F624ZZ bearings (instead of 608ZZ)
- 16 tooth GT2 pulleys
- 0.9 step angle / 400 steps Nema 17 motors for XY
- 1.8 step angle / 200 steps Nema 17 motors for Z / E
- J-head clone 0.5mm nozzle / 1.75mm filament
- Ramps 1.4 + LCD
- Mk3 aluminium heatbed + borosilicate glass plate + SSR
- 8mm linear rods + selflubricating bronze bushings
-12mm linear rods + bearings for Z axis
- Wade extruder (bowden)
- laptop style 12v 10A PSU


The Z axis design is "borrowed" from the G&C printer but it uses more printed parts, different aluminium extrusion lenghts and the motor is mounted at the bottom. Because of this I used 360mm vertical extrusions.
The MK3 heatbed sits on top of a 3mm Dibond plate.
The plan is to use a IR probe (from dc42) for auto bed leveling but for the moment the build plate will be manually leveled because I use it on another printer.
Currently the plastic parts are printed in PLA but will be reprinted in ABS after I wire the heatbed and make some minor.
The only plastic parts that are not modified are the motor mounts with their rod holders.

It will be upgraded with the following parts: 24v power supply, 24v Arduino Mega / Duet (which is intended for a Rostock mini but...), E3D V6 hotend, 24v fans

Cable management is a mess at the moment, I just wanted to see how it works. I will post pictures of the print quality after I fine tune the extruder.

Any suggestions?
