I typically start jobs by moving the tool to the top of the workpiece (as shown in 360.png below). The issue is, G92 doesn’t work in Repetier Host. My solution: disconnect and reconnect in Repetier. This sets the axes at X0 Y0 Z0. This seems to work most of the time. However, sometimes after the disconnect/reconnect, the gantry drops. In the mpcnc.jpg below, the shadow shows how the mill dropped from the start position after disconnecting.
How can I get G92 to work? Or, how can I prevent gantry from dropping?
Other info: RAMBO board (not sure which version- how would I find out? bought from V1 ~1.5 years ago) seems to be running Marlin 1.0, Repetier 2.1.6
Grateful for your help. Thanks!

You’re doing ‘G92 X0 Y0 Z0’?
I remember problems with this on older firmware. Updating to a newer version of the firmware would solve it. I haven’t heard of the problem in a while.October 11, 2019 at 6:20 pm #117595October 11, 2019 at 7:49 pm #117598October 19, 2019 at 3:37 pm #118406
I reinstalled the firmware. It seemed to change the behavior, but not fix it. Now if I run G92 X0 Y0 Z0, it seems to partly accept it. For example, if I turn on the machine the x axis is at 0. If I move to X50 and then do G92 X0, the log shows X:0.00 but the manual control still shows X at 50. However, if I try to move -10, it moves +40 and then shows x40 on the manual control?
I’m stumped. Should I try to do the firmware again? I am running dual end-stops in case that contributes. Should I try a different controller, maybe cncjs (was going to try Octoprint but it needs python 2.7?)
edit2: just noticed I was using arduino 1.8.5 will update and try again
edit 3: now G92 behavior same as initial situationOctober 19, 2019 at 4:38 pm #118412
Repetier does not recognize the G92 command as far as I know.October 20, 2019 at 7:59 am #118461
Goodbye repetier then. Thanks for your help Jeff and Ryan. Btw Jeff, I’ve read so many of your posts, I always read your username a Jefe (ie spanish pronunciation). Anywho thanks and I think I’ll try cncjs and report back.
update: WE ARE BACK IN BUSINESS! The cncjs desktop app did the trick. Thanks gents!

It happens a lot. Ryan sometimes calls me Heffe too. But my last name starts with Eb, and back in the aol days, I tried jeffeb, and then that got full of spam so I went to jeffeb2 and then that got full of spam so I switched to jeffeb3, then spam filters were invented.October 21, 2019 at 8:24 am #118594
