General Mach Discussion / CNC MISSING THE ODD STEP

« on: August 04, 2011, 08:32:47 PM »

Hi Can anyone give me some advise on my Machine missing steps.
I have a TB6560 driver board. When machening I loose the odd step after a few minutes of working.
I disconnected the screw from the stepper and it did the same. I change to 36000mhz but still no difference.
I reduced the velocity and acceleration , it is slightly better but still looses a step every now and then.
It appears to be getting worse. My gut feel is the TB6560 is the problem(chinese driver so I guess I goy what I paid for.)
Am I on the right track?
Jim

General Mach Discussion / Setting up safe limit switches

« on: December 09, 2010, 09:45:49 PM »

Hi all  I am a new user to Mach3 and have built a homemade 3 axis CNC router. I would like to set up limit switches in case somthing goes wrong.
My question! micro switches have a common and a NO and NC terminal. I am using a TB6560 driver .
Where do I place the wires to me if I have the 5v wire as common where does the ground wire connect as I do not want a dead short between the two.?
Keep it as simple in plain language please.
Jim
