yes my z axis drop is about 4″ with tool in. I wish the spindle mount was higher on the pipes but I guess it would hit something? i dont know I ‘m in front of the machine at the moment. I was planning on printing the new middle and z anyway soon.
The movement issue is the killer one obviously. no problem found, intermittent issue, it’s a nightmare. I appreciate your quick response and suggestions. I the end it is all operator error some how. I just have to figure it out. You make house calls? I’m pretty sure the local cnc repair techs would either laugh me off the phone or back out the door after arriving and seeing my unholy “not from a manufacture!?!?!” machine.
