Orders for the SLS parts have been placed so hang tight for the actual photos.
We uhmmed and arred about launching the E3D Hotend Upgrade for BCN3D Sigma, but seeing the demand from a number of professional organisations as well as individuals, it was time to let the greater public be able to easily ask us for them.
To date, we have been offering turnkey solutions for the upgrade where customers have requested that they receive the machines ready to go. This does come with a price to cover the labour costs as well as warranty of the service.
With the E3D V6 hotends, the Bondtech QR extruders and our own design of mounting hardware, you can turn your otherwise perfect Sigma into a a machine with the best in class hardware.
With the exchange of the hotend to E3D, there is the option to convert your machine to use 1.75mm filament as well. Such a kit was first created for a customer in Japan doing what we feel is a huge service to that country! Customers that have 1.75mm printers already have also been asking for this. The question of course of 1.75mm as a Bowden has been asked and we are happy to say that due to the reliability of both the hotends and the Bondtech Extruders, the system works impressively well.
The video below shows a conversion we completed for a customer in Switzerland being tested using a 0.25mm nozzle. The print is the hollow Draudi model to demonstrate the retraction speed capability of the upgraded machine.
So in the kit you will receive:
- 2x Nylon SLS hotend holders
- 4x M3x0.5-20 socket cap screws
You can reuse the existing screws heater cartridge thermistor, and fans.
As of firmware version 1.2.7 it is a rather painful process to produce the modified Marlin HEX files. We thus suggest that you reuse the original thermistor and heater cartridge that came with your Sigma.
For the machine to function correctly, you will need complete the temperature PID Tuning program.
Full instructions will be made available as soon as we are able to take photos.
