Background: I am Giving up on MKS DLC V2 and I put the SBASE 1.3 on my CNC router. Even though I originally bought the SBASE to run grbl-LPC, it was still running the Smoothieware that shipped with it, and it kind of worked for a while, but I none of the senders I tried actually talked reliably to it, including UGS and Candle. I tried current Smoothieware as well as updates to UGS, both 2.0.7 and 2.0.9, platform and classic, and Candle wasn’t configurable to talk to Smoothieware and UGS kept telling me that grbl wasn’t done booting when I selected Smoothieware. (I occasionally got it to work by first telling it to connect with grbl, then disconnect, then connect with Smoothieware, but that wasn’t reliable and became less so.) I even updated the computer I was running on to Fedora 35 with all updates to make sure it wasn’t the OS on the computer…
So now I put the latest grbl-LPC on it; the
bbba813 sbase build from the releases page. Now UGS can talk to it, at least partially, though the DRO never displays anything, as if it never recognizes the position reports. Candle seems to recognize them correctly. So far, so good.
My machine homes X and Y to the lower left (1st quadrant), and Z to highest position. (When working I zero to top of stock=0 and -Z to cut stock. I don’t really care about machine coordinates as long as they can be consistent.)
$H homes X and Y, but not Z. If I disable soft limits, Z moves in the correct direction when I jog, so it’s not that Z is not connected correctly. But I can’t get it to home Z. I have tried
$23=7 to see if that has an impact on what it tries to do, but the Z axis never moves during homing.
I have also connected a dumb terminal and confirmed that the home switches are reporting right; e.g. that normally I see
|Pn:P| and that I can individually trigger the stops and see
I’m really not sure what to do next to figure out why Z is not homing.
