Probably the 5i25. That would fix part of the issue with not being able to drive the Z fast enough. I'll also have to look into auto switching from joint mode, so I don't accidentally jog one of my x joints. Can you set parms in the INI that are just used by the world mode? Like X axis speed? The soft limits? ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
