As the topic notes, there’s a new board from Bart that uses an ESP-32 S3 and has support for external stepper drivers.

Edit: copied from that page:

Features

ESP32-S3 CPU
(8) Stepper motor connectors
(10) Input inputs
(4) 5V outputs
0-10V Spindle interface
Isolated RS485 Spindle interface
(2) MOSFET outputs
Standard CNC I/O module socket that can add inputs, outputs, MOSFETs, etc.
RJ12 standard UART interface for pendants and display.
Micro SD card socket
USB C primary USB/UART interface
Secondardary USB C connector that can be used as a UART. It also support the future use as a host for devices like joysticks and jog controllers.

Second UART USB for pendants, sounds better than rj11!

Different application. The CYDs and M5 Stacks do not have a compatible interface. This would be more for using a mini-PC or a raspberry Pi as a sender.

Note this comment on the wiki page:

At this time FluidNC has no support for any devices in host mode. The connector was tested using simple example sketches of host mode. There is no guarantee that FluidNC will ever support this. This was just an attempt to future proof the controller and work as a development platform.

Uff that looks amazing for an XY(dual spindleZ)

I was thinking of using one for my MPR&P V2 build, but this $58 board from Elecrow to the US with reasonable shipping speed and tarrifs is more like $150. Not going to happen :slight_smile:

I was thinking about using a set of closed loop steppers all around on that build- I have a set.

Instead I may just outfit that build with a Jackpot and V1 stepper motors.

Yeah, tariffs makes things difficult, china is making shipments directly to our country with a reasonable price (dhl direct shipping) thats what i used for the screen and one of Bart’s controller.

This caught my eye, that is alot of stepper motors, this board seems like someone asked him to build it.

I think he was just trying to take advantage of the extra pins available on the ESP32-S3.

Ouch! Half that to here: $58 + DDP Economy Express(6-11 Business Days) $11.35

I’ve found that shipping option to take about a week or so in the past.

I ordered a Corgi to be used with a “Secret” CNC I’m building….well, it’s a secret from my financial advisor for the moment, AKA my wife…
