I am using endstops but how to I tell the marlin firmware how large my area is so thta when I home it knows to go to the end and stop? its going about half way now.

Typically we do not use endstops.February 18, 2018 at 8:58 pm #53336
I don’t use end stops with my MPCNC, I just move the tool to a good place for 0, 0, 0 and reset those locations with the buttons in bCNC. I don’t think your firmware would want to know the size of the work area directly, but maybe some CAM software has settings like that? I didn’t find anything in EstlCam like that though.
Knowing that I’m zeroed over a corner of the material and that what I’m going to cut will fit within the material seems to be enough at this point.
I don’t know if this is helpful. 😛
One last thing: the firmware might need to know if you’re homing to min or if you’re homing to max.February 19, 2018 at 5:01 am #53342
Usually if it’s stopping half way, or anywhere that’s not engaging the stops, you’re getting electrical interference. Mine does that occasionally. I just hit home again. So far I’ve never had an issue during a cut, not sure if the firmware even recognizes end stop hit during a cut.February 19, 2018 at 8:52 am #53346
There are defines X_BED_SIZE and Y_BED_SIZE in the configuration file that are used to set the coordinate limits (X_MAX_POS etc.). I think they get ignored unless you define software end stops.February 19, 2018 at 9:59 am #53351
You are correct, I was hopeful that I could have the software somehow help me to calculate that.February 19, 2018 at 10:00 am #53352
I dont have any electrical issues, that is not the cause.February 19, 2018 at 10:14 am #53353
HubertParticipantYou are correct, I was hopeful that I could have the software somehow help me to calculate that.
I believe the values are in millimeters. There is a comment in the code that you can also set/probe the values with the M211 command.
