Hey everyone,

For some reason when I home the machine X and Y axis, the coordinate always goes back to -453 and -206. I tried the knew 1.86 and the old 1.85 both version doesn’t seem to fix the problem.

Any thoughts why this may occur and how can I fix it ?

Thanks :slight_smile:

I don’t think this has anything to do with SPJS as that is just a way to send the data to the serial port. You seem to be having no issues sending data to the serial port. However, you do seem to be having configuration issues on your TinyG. Why don’t you show us what your $ and $$ settings are?

Hi John I figure it was my tinyG firmware being out of date I have updated to 440.20 and the issue of homing seem to be resolved. Thanks.

By the way, the new firmware uploader works well.
