Quick rundown… Hello World worked fine, setup a test project and the laptop turned off halfway through so it stopped the project (lesson learned there!). After trying to reboot the project, found out we had never setup homing and so I went through the process of doing that.
However, it is not working… The z-axis bounces about an inch one time no matter where it is, and then the machine runs to the far right corner (where it should be going) but they do not back-off and reengage as they are supposed to and Carbide Motion does not show all values as 0.
I am a newb but wanted to be sure you had correct cables to the correct port on the board. If you look close enough you will see written on the board where they need to be.
Usually problems with homing are mis-plugged / swapped switches — yours doesn’t sound like that, since it gets past the homing operation — the not backing off the switches is odd — if the defaults actually are being retained, then I suspect that there’s some deeper problem. If the standard troubleshooting things (power down, reset PRAM and SMC if using a Mac, uninstall and reinstall the driver and attendant apps) then contact support@carbide3d.com and we’ll help you determine the difficulty.
Mine dont re engage. They home just like your video.
They hit home, then back off 5mm.
They never stop on 0,0 for home.
It’s the line
$27=5.00
Oh yeah, and 850 was a tiny bit too wide for mine. had to go 845mm on x, i think.
I believe what we have here is a misunderstanding of terminology / workflow.
When the machine homes, it determines the machine home / origin, which as @jdg3 noted, is defined as 5mm off the switch contact for X, Y, and Z by the $27 setting
Once machine home is set, one can then manually jog to the desired origin and zero out the axes using the interface, or use one of the non-reserved (G55–59, G54 is reserved for use by Carbide Motion) work coordinate systems.
