Other Driver Solutions?

I've had bad luck with my MaxNC mill so I am looking for a different drive system.  Ideally it would run small hydraulic motors which won't burn out in an overload like steppers.  But I'm willing to consider a different stapper system that's cheaper than MaxNC's since I already replaced the driver board and several motors once.  I once saw other systems in a magazine at a now dead machinist's but I don't remember them or the magazine name.  Any leads?

This forum used to be for builders who I hoped might consider mentoring me on the hydraulic solution, if any are still out there, please advise. .I should be able to hook up the chips to control a proportional hydrauliv valve to a Rspberry Pi but I don't know about the position sensors and software to run the G-codes, etc..

Thank you.
