## Make my own EtherCAT device 9. About time. Step generator
This was something, I almost gave up. But here it is. A working step generator.
Actually, not one but two step generators for the EaserCAT 2000 board.
For a step generator it is all about timing, timing and timing.
I'll walk you through what I had to do to get it to work.
Biggest changes this time are in the [Firmware folder](Firmware).
The [Documentation folder](Documentation) has details on the second step generator.
A small but fatal bug was fixed in the EEPROM_generator.
For all details, read the git log. Too much to mention all.

## Make my own EtherCAT device 8. EaserCAT 3000
Introducing the new **EaserCAT 3000** board. It's an evolution of the EaserCAT 2000
and intended to be used in my plasma cutter. It features four stepper driver outputs,
input for a THCAD arc voltage card, an encoder, an analog output (for spindle +- 10V),
eigth digital inputs, four digital outputs, plus some 12 I/O for any possible extension.
The KiCAD files are in the [KiCAD folder](Kicad/Ax58100-stm32-ethercat)
