Hi Forum
I am having trouble correcting backlash on my cnc. I am using mach 3 currently and the machine has ran well for several years. I am starting to notice my circles are not circles anymore. I have tried adjusting my backlash in setting but that has not helped. This is only happening on my Y axis. I have made sure that everything is tight on my gantry. I have re zeroed my machine a couple times. I have tried a radius into the cut in my cut and nothing has seemed to help.
I did have a slight crash a few weeks ago when my machine lost it position on the table and it hit the hard stop. it was very small. I didn't notice anything after this. I have been looking at videos about setting steps per inch on my motors. I did this along time ago and I don't think I need to play with this again.
1 other thing I have a large gantry of about 5 feet in length and use a two motors 1 is a slave. I have the machine set so when I zero my gantry to the machine I have 2 limit switches to make sure that it is square.
Any suggestions would be great.
thanks.
