Hello, I'm new to using Mach 3, I have it up and running but I am having massive issues with homing and the spindle... Would appreciate any help anyone can give me.
When I try to "ref all home' or 'ref z' (doesn't matter which axis) i get the same error in that when it hits the combined limit/home switch Mach stops and says "external e stop requested"
My limit switches are hooked up to the same input (10) for Z++, X++ and Y++. A++ is separate (11) and the machine E-stop is separate (15). I'm using an ESS smooth stepper and G540 bob and I for the life of me can't work out why this is happening...
My second issue is the spindle (PWM controlled) takes about 3 minutes to ramp up to any decent speed, I can't work out why this is taking so long either but I have checked the average voltage on the output and it seems like it is the PWM signal that is very slow to ramp up rather than within the spindle hardware. Any ideas how i can fix either of these? I would love any help that can be provided!
