Pressing "Home" Causes Z Axis To Crash
Posté : 08 févr. 2023 05:09
Hello everyone, I am very new to CNC and I have purchased a 1.5 Makerfr second hand off of Craigslist.
It took me awhile but I was able to finally flash my GRBL and TFT boards, get the UI to display on the screen, get the touchscreen calibrated via the SD card, and play with moving my axis' using the nunchuck and the touch screen functions to test the motors. (The nunchuck actually stutters quite a bit, maybe someone can tell me what is going there?)
I have not tested anything yet in regards to running any G-Code Programs, I still want to work out a few more kinks before then.
One of those that concerns me the most is that when I press the "Home" button on the touchscreen and the X and Y axis appear to move into the correct position (bottom right hand corner of my table) however the Z axis raises so far that it begins to crash up higher than it is supposed to and I have to press the emergency stop to prevent it from seamingly breaking itself.
I understand the mpos units are my "Home" coordinates, where in the UI or arduino code section am I able to edit those units? Why is my Z going past it's own physical parameters?
Again, I am a complete novice to CNC machines such as this and any and all help would be appreciated.
Thanks,
-Matthew
