Thread: Problem with homing
Threaded View

I have a three axis router that I built about three years ago. It has performed well but has the occasional problem so I decided to move away from the parallel port connection. I have built a new control system using CS Labs IP-M controller with Leadshine EM806 drivers.
I have now done an initial test which worked out well apart from one problem.
The problem is with the homing routine. The machine has limit/home switches each end of X and Y and at the top of Z all wired in series.This has not given any trouble with the old control system but with the new system when requested to home it moves to a switch and stops with emergency stop activated and doesn't back off. The odd thing is that if I go to ports and pins and enable the home and limits for just one axis it homes that axis and backs off OK. This works on any axis where the switches for that axis are enabled.
Any advice would be appreciated.
George
