I like the Remora-Project.
At the moment, i try to port the SPI-Version to an ICE40-FPGA with Opensource-Toolchain.
Only Just for Fun and to refresh my FPGA-Skill's.
EDIT: can not get it to run

Just dropping in to say hi to Cakeslob and let him know I'm looking forward to seeing progress on the linuxCNC front with regular 3d printer control boards!
In particular I am hoping to use the Spider King board!

Bari, I could not help myself. A W5500 version on the way. A RP2040 Remora port will help keep me busy during the weekends whilst travelling for work for 3 weeks.This is shipping now for ~$18, Rpi2040 with Ethernet: docs.wiznet.io/Product/iEthernet/W6100/w6100-evb-pico

My ICE40 "Port" works
Not good, getting join errors if i move too fast, but i can move my stepper <3

Cool, which board are you using?

PWM and closed loop now also works on my ICE40,
but i'm afraid i'm running out of logic cells,
I also don't use an IP-Core like Mesa but pure logic in Verilog.

lookin good. I am wondering the advantage of using remora over hostmot2. I can assume it smaller in size? hm2 would already be a little too big for the ice40 right?

the ice40 i had lying around at home and i felt like playing with it
otherwise there is no reason for it, neither cheaper nor better.
ok, i can do everything in logic without an IP core but is that an advantage ?
