I`m not 100% sure what controllers are on the machine but I believe they are custom made from Speedline company - can`t check at the moment because machine is in our warehouse and now they have put like 100 pallets in front of it.

I have to check if I need any electric stuff off the machine - maybe motors only (I work in electronics industry and over time I have gathered most of the components already).
But regarding stripping it to parts I have not decided yet. I also like Doddy`s idea though - I couId take that black block of metal and gantry off the machine and transform it to small cnc. I would only need to make gantry a bit higher and stronger.
Actually building frame from scratch is not a problem because I have access to welding machine. But I`m sure that with my current skills I`m not able to make it as straight as this machines frame.

That 25 micron accuracy was taken from datasheet. From where does it actually come from? Is it the screws or something else?

Btw I also happen to have four quite solid servo motors (two of each), brushed I think. I have attached their datasheets. Do you think that these would be suitable for cnc applications? They should pretty good because they cost around 5000 and 10 000 euros respectively when new.

Doddy, yes I´m from place that is around 30 km out of Tallinn. I guess you must have been here on vacation then. It happens....but hey, both are good way of spending you hard earned money.

Sorry for late reply. I`m new to this forum and for some reason no notification was sent to my email when you replied.
Hi Ryzen,


What is the resolution on those motors you have? The ballscrews on the machine are 20mm per rev? Make sure you get to the desired resolution and have enough speed/torque/resolution to do what you want.


Those motors are my field of expertise.
But they must be superior to nema 23 @ 4nm.


Doddy mentioned having an enclosure.... That is good reason to build within the current frame space.

Noise dust and mist removal is a underestimated feature.

Grtz Bert.
