New interesting 'LPT' device available..

I stumbled on this neat little 'parallel port creator' www.machmaker.pl/linumeric-lpt-v3-en the other day.
Has anyone of you got any experience on this 'ethernet to LPT' device?

Thanks,
Bert

Not sure, never heard of it, but considering that Versions 1 and 2 were using USB and were also promoted to give you a working LPT interface for LinuxCNC I would be somewhat skeptical.

Looks interesting, seems to be Ethernet to spi to arduino. Unless it’s significantly cheaper than a 7i92, which in effect gives you the equivalent of 2 parallel ports, I know which way I’d jump.
Another thing to consider is that you may need to run a base and servo thread, rather than just a servo thread.
It may fill a need for some people.
Unless someone is willing to take it for a test drive or take a chance it’s all just opinions we can give at the moment.

I think ( I guess) how it works is quite clever, Its actually a buffered device
so base thread invocations simply queue read or write operations
in their driver until the servo thread function that does the actual
communications, sending the queued requests. This allows compatibility
with LinuxCNC software components.

The same, but without ETH, from the same guys and this one uses STM32 BluePill.

The prices are out of this world, and they insist on keeping it secret, i hate that.
Go buy a Mesa and enjoy using it.
Those LPT thingies are much slower, have less IO, but cost more than Mesa !?!?!?

More ?

Surely not ?

-
67$ for 17 limited pins
89$ for 34 very fast pins that can do input or output on all pins
So yes, it is more expensive, by a lot.
Should have been 40, that would be very reasonable for someone in need of parallel port

Holy cow batman.

I guess there would be a device driver in the middle of it all that virtualises the parallel port. In the spirit of linux one would guess that would be open source.

Not sure where you got touse prices from but they seems to provide all you need to make one your self.
Schematic, BOM, Gerber files, programming instructions and software in a binary. So no open source but still...

It's a quite simpple design and I'm tempted to make my own PCB with levelshifters/isolators included so that you don't need another BOB to interface with the motor drivers.

We did a fully-open source Remora controller for these type of simple LPT based machines. It uses the Ethernet component as a fully real-time device, not buffered.
