LGX Lite configured (by default) to run HOT (out of spec)
https://www.bondtech.se/product/lgx-lite-large-gears-extruder/
Recommended stepper motor Current (using LGX Lite) : 0.45 to 0.60 A
However, RatOS configures it quite a bit higher at 0.707: https://github.com/Rat-OS/RatOS-configuration/blob/v2.x/extruders/lgx-lite.cfg https://github.com/Rat-OS/RatOS-configuration/blob/v2.x/steppers/ldo/36sth20-1004ahg/24v-0.7a-e.cfg

Beacon revH - bed mesh hangs klipper/mainsail
Just added a Beacon revH to my RR400. Updated the printer.cfg, removed the references to the previous probe (klicky). The probe itself seems to work fine for Z homing and Z tilt calibration. However, when I try to do a bed mesh, the printer becomes unresponsive at the end of the scan. I've tried various configurations for the bed mesh. I've seen others use as high as a 50x50 mesh with the beacon probe. I've tried lowering the probe_count all the way to 7x7. 
[bed_mesh]
speed: 200
horizontal_move_z: 15
# 10 off each max range, plus the y-offset
mesh_min: 10, 37
mesh_pps: 390, 390
#algorithm: bicubic
#mesh_max: 380, 380
#probe_count: 50, 50
#probe_count: 15, 15
probe_count: 7, 7

Attached is a klippy.log that should show the startup, homing, z tilt, and attempted bed mess (default-testing). The system appears hung once the following appears in the klippy.log: 
Sampled 27705 total points over 2 runs
Samples binned in 49 clusters

With the lower number of samples it does eventually continue, memory usage approaches 1G. Then Mainsail goes into a retry loop, and Mobileraker goes into an endless notification loop about the printer now being in Standby. The host system is an RPi4 2G.
