My build is 24×24 built to the recommended sizes using the calculator in the instructions. It also has functioning dual end stops.
Why is it, if I move the x and y out to say 400,400, then zero it out and then try to home it, they gantry will move only to 100,100 then stop. If I home it again, it will then move to the limit switches. It’s like it thinks the machine is only 300×300.
I looked at the marlin files but I didn’t see anything that was obvious to me.
(BTW I’m a novice so don’t yell at me please.)June 20, 2018 at 10:09 am #61944
I think there is a limit setting in the firmware that sets how far it will move before it gives up on a home operation.June 20, 2018 at 10:18 am #61946
Mike is correct. I have not changed the default build size in the firmware. It is set to 200mmx 200mm. You can either change it or just home twice.
Usually I am within 200mm of “home” so I rarely notice it. Easy enough to change.June 20, 2018 at 10:19 am #61947

Any idea what it’s called or where it’s at?June 20, 2018 at 10:20 am #61948
Machine size, configuration.h, little past half way down.June 20, 2018 at 10:34 am #61949

Ah ! same as for 3D printing and bed leveling. Thank you.June 20, 2018 at 12:03 pm #61951
I usually just manually push the carriage over toward 0 for the X & Y, that way the home function doesn’t have to “drive” so far.June 20, 2018 at 5:29 pm #61980
