I have been testing out grbl-HAL using a Teensy 4.1 board and Phil Barret’s Breakout board as a replacement for grbl-LPC MKS Sbase. link below

With this combination I have been able to stream gcode to my custom laser at roughly 3 times the speed of the grbl-lpc. My test file ran at about 15,000 mm/m on LPC and on HAL I have so far been getting 50,000 mm/m stable. The main factor was being able to increase the block buffer size to 1024 in planner.h

Laserweb initially connects to this board but shortly disconnects. What would be involved in making them compatible?
