Hi guys!

I have a few old machines with dead controls, one of them is a press brake with fully functional hydraulics but the main chip was defective. For the sake of learning linuxcnc i am trying to retrofit these machines, now it's time for the press brake.As i've done my homework, i found out this system is driven by a proportional valve which receives a given voltage to let the hydraulic be fully closed, or open.For this i've been searching a mesa card that can provide this analog output, and couple it with a linear encoder, to better tune the movement of this new "axis".Although this seemed simple at first, after opening the press brake i found the proportional valve is "many valves" and i can't seem to find a way to "hack" into this system and add my own connections.I found out that this is driven by a bosch PL6 0811405060, but i'm not sure as to what all the valves are doing.There is also a panel of resistances which have a label matching each of the valves near the hydraulic pump, so i can figure they are related.There are not any manuals available for the press brake, so i'm trying to get some hints on the web as to what i could do to start this retrofit !

I don't sure and it is not specified any info for the machine but the most reasonable thing is to contact with the manufacturer and request spare parts list if possible. Or buy complete documentation if still exist.
