Self Sourced Voron Trident 350 - Yet Another India Build

[d4h]

I’ve parked the toolhead assembly for some time due to the struggles with the H2 V2X extruder. Dc3d was kind enough to reprint the entire lot of printed parts for H2 V2X using ASA. They seemed to be holding up better than the ABS ones until the extruder mount spontaneously snapped. May be I’m doing something wrong. Probably tightening too much. This time around I was more careful. I’m not very confident that the H2 V2X extruder assembly is not going to come apart mid print. I’ve called off the toolhead build using H2 V2X.

Page 23 of the StealthBurner Assembly Manual has this joke -

DON’T OVERTIGHTEN
Tighten until the plastic bends and cracks. Back up 2 turns, discard parts, reprint and try again.

I’ve already done that two times!

I’m considering four toolhead options
(1) Fallback to stock SB + ClockWork 2 - I’ve sourced some cheap generic gears to finish the CW2. The thought of crimping and running loads of wires from MCU to the toolhead is not looking very appealing.
(2) SB + ClockWork 2 + EBB - I’ve rigged up an umbilical by wrapping a piano wire and the 4 core wire from BTT CAN Cable in a heat shrink tube.
(3) SB + Orbiter 2 + EBB - I sourced the Orbiter 2.0. The extruder mount looked straight forward in theory. I tried it but it did not fit properly.
(4) Xol + Orbiter 2 + EBB - the Delta fans mentioned in the Xol BOM are still not readily available here. Plus I’d have to carry out mods to the Z spacers and the front idlers.

I’m inclined towards (2) as a now. Not having a working 3D printer at my disposal limits the choices.

I completed the A/B Motor and Belt assembly. The shipment from Biqu landed up just before Christmas up after about 2 months from order date. By that time I had already ordered a new set of 2x Nema 17 Stepper Motor 17HE19-2004S A/B motors and installed them.

I’ve installed the CNC Voron Tap Sensor V2.1. I had a potential clearance issue on the left side of the gantry where it looked very close to the extruders for the belt to pass through. I struggled with the issue for some time. De-racking the gantry by loosening the bolts on the D Aluminium extrusion as in Solving Gantry Racking video seems to have solved it. I struggled with the belts as I had cut them too close and there is not much spare length at the ends.

I’ve partially completed WIRING section of the assembly manual. I did discover some errors in the wiring diagram that I had created. I’ll update it at the end of the build. I used 1m cable duct chopped up in 6 sections (2x 380mm, 4x 60mm) to conceal the wiring. I could have done with a little longer duct. But I’m happy with the outcome. The motors are disconnected. It’s just enough to do the first power-on.

Software installation is partially complete.

• Raspberry Pi 4B is up with Klipper, Mainsail (and fluidd as well)
• BTT Octopus Pro is flashed and is visible in Pi.
• U2C is visible in Pi as a device
• EBB 36 is flashed with Katapult. I need to hook it to the umbilical and flash the Klipper on it.

Login results from Pi after first power-on. Fingers crossed - all boards are working as expected!

I finally figured out why I was having issues with the toolhead assembly.

StealthBurner Assembly Manual says.
FAN PREPARATION
Remove the front of the 5015 fan. Clip off and file down the stock mounting ears.
There’s a trimming jig STL included in the release to make this task easier.
PART COOLING FAN



The front view of the 5015 is not apparent from the diagram. What I was doing wrong is after clipping the ears off, I was putting front of the 5015 fan back again before inserting it in the StealthBurner. No wonder all the extruders were not fitting properly! After some measurements and reading through the manual again, I’m happy to have located the issue. This had caused almost a month of heartache.
