It's a Fagor 8055i Control that was installed back in 2007 from what I can see. I have looked thru the manuals and they don't have a ladder printout, like they normally would/should. I believe its called Boolean??? I can somewhat figure out what is going on, honestly it looks similar, and I may

I don't know how fast you are moving this machine, but years ago I retrofit a large water jet that had two motors on the Y axis.The gantry weighs probably 1000 lbs since it carries 4 jet heads and the Z axis is manual but built into the gantry. The entire machine is massive. The

Thanks for bringing this up. I forgot to consider the critical speed of the screws! I will need to increase the lead I was initially planning to use on the X and Y. The X only has a travel of 33 I was initially thinking of using a 20mm x 5mm pitch screw. With max velocity of 400-600IPM,

Maybe I'm not visualizing the setup of this machine but it seems like it might be easier to use two motors utilizing the existing racks. Of course that would probably require planetary gear boxes on the servos with a 2 inch pinion.
