Commit e05c6354 changed the internal step compress queue from 64bit integers to 32bit integers. However, that commit broke the proactive flushing of moves that could produce more than 64K steps. This could lead to large memory allocations and cpu slow downs on printers that had a very large Z axis - possibly leading to a "Timer too close" mcu shutdown. Correct the code so that it properly generates a 64bit flush clock. Also, be sure to only expand / memmove the queue when there is no room for a new element at the end.

Welcome to the Klipper project!
This project implements a 3d-printer firmware. There are two parts to this firmware - code that runs on a micro-controller and code that runs on a host machine. The host software does the work to build a schedule of events, while the micro-controller software does the work to execute the provided schedule at the specified times.
See the features document to find out why you should use Klipper. To begin using Klipper start by installing it.
There is also developer documentation available.
