CNC use / chilipeppr

garlicbread

Hi,
I'm interested in using the Duet board for a couple of ooznest Ox CNC's

The stepper motors are rated for around 2.8A, from what I can tell the TMC2660 drivers can provide 2.5A without heatsinks
or up to 3A with heatsinks / fan (and removing the software limitation)
For the end stops I plan to use a custom buffer board to some inductive proximity sensors (blue tipped ones from china)

I was wondering

Does anyone know if the duet board firmware works with chilipeppr?
Usually chilipeppr is used with grbl or tinyg/g2core
It also uses returned data from the board to plot the head on a webgl view but I think that differs between different board firmwares
I've seen someone mention they've tried https://cnc.js.org/docs/desktop-app/ with it so far

I'm also interested Offsets (G54 through G59.9) Global Offset (G92)
also spindle control (via RS485)

Many Thanks

Danal

Chilipeppr does not directly support Duet3D/RepRap boards at this time. Chilipeppr would need a "workspace" that either directly supports Duet3D/RepRap, or is "Close Enough". The TinyG workspace is nowhere close... the GRBL workspace might work, maybe a little, I have not tried it. Chilipeppr does make it extremely simple to "fork" and develop... if you wish to create a Duet3D workspace.

CNCjs works with Duet3D when CNCjs is set to "Marlin" mode, and connected via USB. CNCjs can run in "browser/server" or "all-in-one-desktop" modes. However, at this time, running in "Marlin" mode when really connected to a Duet3D, it does not display Work vs. Machine coordinates correctly, and a couple of other things, making attempting to use any offsets very frustrating.

Rumor has it there is a CNCjs 'tab' being developed at this time, for the purpose of directly and correctly supporting Duet, and supporting network connectivity. No date, yet.

And, last thought: Support for G54, etc. was enhanced SIGNIFICANTLY in R1.20, be sure you are running either 1.20 or 1.21 if you do use offsets.
