Hi Tvalen1432 for VG Adjust I do not use it, I adjust it by manual way.
I mean, first of all check the cables on the lower head: electrode (red colour and one by side attached by Allen nr 5 ) and ground cable attached to the table usually it has silicon to prevent dirty to go inside the bolt, look also that cables are not sulfated and has good connectivity.
Second and very important look for water quality, should be 24 on the screen that means about 15 microSiemens, be careful not always shows the correct value so clean the 2 pin sensor in order to be sure.
With a digital tester just look on the input by AC power on main switch on the generator, should be around 200 VAc, if so you must look on the power supply of the generator that is located in the bottom of it. Look that is adjusted at your AC input value so 200Vac I can't tell you where to look cause there are different power supply. The Technical service when machine gets installed should look for it, so I guess it's almost done.
Thirdly, give new position to the power feeder upper and lower.
Now comes the adjustment, VG SET. Close all the regulators up, down, aux and fluid low. Put the machine on the midle of the strokes on X and Y axis and Z on 40 mm and thread the wire.
Put the following conditions on monitor, Vo 12, IP 4, SA 2, SB 14 , LQ 2,LR 9, AE 21, SE 1 press Fluid, Wire Feed and machining should appear 71 V on monitor voltage ( right bottom corner of monitor screen ) if not could be adjusted by a PCB in the NC but I don't remember right now by heart, I can tell you if the value is not correct.
Stop if correct and enter the following conditions Vo 4, IP 3, OFF 10, SA 2, SB 3, LQ 2, LR 9, AE 11 and SE 1 should appear 122 V, if not could be adjusted on IAPA PCB the only variable resistor it has. That's how is done.
The table limits are placed fisically in the machine, but the parameters on pitch error and backslash diks is unique for every machine and this one gives the lost motion and also software limits. So you can run just only the system software maybe but don't do it because you must enter in options of the machine and specify which kind of machine you have and could be hard to handle. But the most important thing a part from this is Epack, not all system software goes well with technologies, could broke main unit or OSC unit if wrong. Your FX20K has more power in main units than FX10, just have a look on the front connectors you will see they're different.
I must understand you don't have the disks for FX10? Please in order to help just tell me and I can send some pictures for adjustment.
Best Regards.
