VIDEO: Tramming & Squaring with Jackpot controller (LowRider v3 CNC but possibly helpful with MPCNC and others as well)

Hi Doug - thanks for posting this probe script and the helpful videos on squaring up. One thing that bit me until I figured it out was the “G92 X0 Y0” line. I was homing Y then X then Z, and then I manually moved the tool over to the area of the board I was going to work on and probed there for what I thought was maximum accuracy. But that line resets X and Y to wherever you probe. So basically I just want to point out that to use the script as written you have to probe Z when the tool is at 0/0 from homing X and Y. Otherwise you can get your tool trying to drive off the table…

I realized there is a built-in probe routine in the firmware (third tab in the middle) - it seems to work but I haven’t tested yet what behavior it uses.

Also for anyone using Doug’s script and the V1E probe kit don’t forget to change the plate thickness to 0.5.

A couple other notes regarding the Jackpot board - I had no problems switching to station mode for wifi - seems to work fine and much faster than reconnecting all the time. I gave it a static address but it should work on dhcp, and then you just go to fluidnc.local to get the interface.

I did however run out of memory several times, apparently (from other posts I found) due to having multiple interface tabs open at the same time from both my laptop and my phone. Having only one screen open seemed to fix that

Thank you!
