Servo drives costing 22 euros for 2 motors

That is nice, i just requested some samples, i have some uses for it regarding Linuxcnc! Thank you.

By request, here are the config files for this example. Be aware that it uses a single parallel port in mode X, for 4 servo drives and 4 encoders so it has only 1 input left unused. Also in some cases the motors will run at will as they do not have enable inputs, if they go to an hard stop it will burn the mosfets or/and motor.
I case you do not need 4 drives, you may configure one of the outputs as enable out and wire another mosfet that will stop the power to the drives.

Hello. Can I connect this board via Pluto-P or MESA in servo driver mode?

With Mesa yes, pluto i never used.

yes, pluto is a fpga, a boy used that one.

On one site where they discussed this board, they wrote that you can make a current limit on the arduno. Apply ACS712 Sensor

There are much cheaper and better alternatives now, like the 43A or the 30A ones for arduino, they look like they do have some type of feedback for current limiting or disabling the drives. I did order several of both types so i will test them when i get them and report back. At the price of 7 or 8 $ a piece, well worth investigating.

Note that the chap who wrote the LinuxCNC Pluto driver says that he found then flaky and that they simply wouldn't work at all with some parallel ports.
I probably wouldn't recommend Pluto-P for new builds.

yes, I also meant to use the pluto in case it already has one,
also because using a bare h bridge is better to have a faster servo thread, I used a PCI and managed to go to 8khz
with significantly better performance.

Why the fourth axis is linear? Do you have tested the fourth axis? I think it would be rotational axis
