Use OrcaSlicer and other slicers - directly in your browser with SimplyPrint's online cloud slicer. No installation required. Slice your Kentstrapper Bold 755 models from any device, anywhere in the world!
Automatic Profile Updates: Profiles are automatically checked and fetched from the slicer GitHub repositories every day, as well as from our own open-source community-driven slicer profile database. This ensures you always have access to the latest profiles.
Note: Other slicers, such as Simplify3D, ideaMaker, SuperSlicer and KISSlicer, aren't in our cloud, so we don't track their profiles. They may still work well with your Kentstrapper Bold 755: check the slicer's own documentation or forums for a profile. You can also contribute profiles to our open-source slicer profile database on GitHub.

Kentstrapper (Kentstrapper srl) is a Florence maker of professional FFF printers. Brothers Lorenzo and Luciano Cantini started it in 2009 from the RepRap project and founded the company in 2011; its Zero (2014) was its first printer for professional use. It builds CoreXY and Cartesian printers from 320 mm cubes up to a one-metre machine, sold or rented; the customers it lists include Italian fashion and leather-goods houses, manufacturers and research institutes, and it targets technical schools.

Mixed: an open Klipper base, open filament and an open-source slicer, but Kentstrapper's own firmware changes, parts catalogue and documentation are not public; it works on a direct-support model.
Firmware and custom firmware ●●●●●
Current printers run what Kentstrapper calls a customised Klipper on a Raspberry Pi and 32-bit board. Klipper is open source, but we found no published source for Kentstrapper's changes: its GitHub account holds 2012 RepRap-era repositories and an OrcaSlicer profile repository.
[3][4][9]
Local control and integrations ●●●●●
The Zero HS and Zero PRO run a customised Klipper on a Raspberry Pi, connect over Wi-Fi, LAN or USB, and are controlled through a web interface with a built-in AI assistant (Clara); an optional webcam adds remote monitoring. We found no Kentstrapper cloud account requirement, but Kentstrapper does not say which web stack it uses or whether a documented API is open to other software.
[4][3]
Third-party filament, slicers and parts ●●●●●
Standard 1.75 mm filament, and OrcaSlicer (open source) is the recommended slicer. The hotend is an off-the-shelf Dragon UHF, mounted in Kentstrapper's own magnetic S.E.M. head.
[3][4]
Repairs and spare parts ●●●●●
Kentstrapper says spare parts are kept in stock and shipped quickly, with support from the team that builds the printers (its 3D Shield programme). We found no public parts shop or repair guides.
[4][3]
Community and documentation ●●●●●
A small user base; manuals and firmware updates sit in a download area and a help desk, and public documentation is limited.
[8][9]
Pros
Designed, built and supported in Florence, with direct support from the people who build the printers.
Klipper-based printers that work over Wi-Fi, LAN or USB with OrcaSlicer.

Can be rented (all-inclusive operating lease) as well as bought.
Cons
Kentstrapper's Klipper changes are not published.
No public spare-parts shop; parts are ordered through Kentstrapper.
Printer interface in Italian and English only.
Priced as professional equipment: the Zero PRO starts at 4,500 euros plus VAT.
