MPCNC auto home issue

Mostly Printed CNC - MPCNC Troubleshooting

Hi All

I’ve just finished the mechanical build of the MPCNC and am moving on to the electronic part. The mechanical build is pretty well documented but the electronics part seems a little less coherent.

I ordered the kit for single and dual end stops but I think my rambo v1.4 board shipped with single endstop fw, this is fine, I’m working to update it to dual endstops.

My work area is roughly 600mm x 600mm and when the X & Y axis are @ 600mm & 600mm respectively using the auto home feature causes an error before it gets to home because, I assume the home distances are greater what Ryan recommends to build.

I did try set the offsets to 600mm but it told me that was too large. Before I load the dual endstop FW what do I need to modify to have the FW play nice with the oversize MPCNC?

Many Thanks

Tony

You need to set the following two defines in the “configuration.h” file to your bed size before you compile the firmware:

// The size of the print bed
#define X_BED_SIZE 300
#define Y_BED_SIZE 300

Ah Ha! Much appreciated Robert…

FYI, v510 will have 600mm limit set.
