****Fairly new**** I have a job I set up. I set up my tool where I have the starting point for the work piece. I have even checked used Check Size to make sure it cuts where I want it to. But when I actually start the job it doesnt go to the right coordinates. So I will pause my job and send it back to the machine coordinates and it doesnt send it back to the same spot that I had originally set it at. Im using a black box controller, have limit switches installed. Just not sure what I am doing wrong. Cant seem to get consistent results.
Are you homing your machine every time you turn it on? Are you remembering to set your work coordinates (set x, y, z zero). Do the work coordinates you set in your CAM match what you've set on your machine?
All axes, or only one axes? - shaft coupler setscrews tight? - grbl acceleration and max rate settings appropriate - any 3rd party (non openbuilds) components involved? Different motors etc?
This is only happening in the y-axis. Most of my components are from SPAM with the exception of my controller and switches. I have nema23 motors. what $ should I be looking at for those settings? $111 =10,000 mm/min $121 = 150 mm/sec
With the offbrand motors (known to be high inductance) we expect it to be around 2500 for all three axis. You can spend some trial and error tweaking upward from there, but don't expect too much
I was setting my coordinates to 0. Didnt know to home the machine everytime I turn it on though. Makes sense.
I landed at 1000 for the x and y. 250 for the z. im fine taking it slow until I get a little more comfortable. Thanks for all the advice!
