Making this a new thread to emphasize the point. 😉

The way his firmware does the probing is for the five prints I’ve used it on so far, 100% spot on. I’m using PETG which is a bit more gummy than ABS and I usually expect about 1 in 5 probes to fail. I just started my 5th print, printer totally cold, no pre-heat, 40F ambient temp in the garage, no pre-clean, blackened nozzle – his firmware did the job perfectly despite these contrary conditions.

If you’re having trouble with probing, I’d definitely give this a shot. I’m using the version linked to in this post (there is apparently a newer version too): [https://forum.lulzbot.com/t/mini-marlin-fw-1-1rc3/2750/1](https://forum.lulzbot.com/t/mini-marlin-fw-1-1rc3/2750/1)
