v3.7.9

• We now preserve startup messages from before a panic. With this change, $ss will show the current startup messages on a clean startup, but if FluidNC panics and reboots, $ss will show the startup messages that preceded the panic, prefaced with [MSG:ERR: Showing startup log from previous panic]
• You can now assign output pins to status states. For example, light an LED when in alarm state.
• Fixed some basic config errors that would force a restart. We only want serious error cause a restart.
• We now show the URL of where the code came from in the start messages. This helps us see if the code came from us or a fork.
• Changed coolant delays. It will only delay on a new M7 or M8. It will not delay if that state was already in effect or if M9 is issued.

v3.7.8

Added latest WebUI (index.html.gz) to release.

v3.7.7

• New setting $STA/SSDP/Enable This allows you to disable SSDP and mDNS to save memory.
• Fixed display of hex numbers in messages.
• Fixed reporting display of Haunyang registers
• Updated RS485 spindle examples to use uart_num:
• Fixed problems with reset during arcs and kinematic segments.
• Fixed crashes with macro buttons

v3.7.6

v3.7.6

New Features

• Added new probing gcode variants G38.6 to G38.9. These are the same as G38.2 to G38.5, but the units are always millimeters (ignores G20) and the move is always incremental (ignores G90). This makes it easier for some senders to control the interface. The WebUI now uses this.
• Parallel Delta Kinematics have been added.
• New Alarms. Grbl only had a single alarm. This locked up the whole system. In reality you might have several alarms (homing, spindles, etc). By tracking multiple alarms, we can better control what happens in each case. We will like take more advantage of this in the future.
• New Macros. We added after_homing, after_reset and after_unlock macros. The new alarms allowed this.
• Soft Limits. We now check soft limits better. Previously we would stop when an arc was about to exceed the range. We now stop before the arc starts.

Note for people upgrading: The WebUI has been updated for the probing feature. You need to load the latest index.html.gz. See this wiki section for help with that

v3.7.5

New Features

• Added (2) new faults inputs fault_pin and estop_pin. These generate a hard stop when activated.
• Add cs_pin to UART stepper drivers. This allows switching the UART signal so more than 4 drivers can be used with TMC2209 like drivers.

Fixes

• Fixed speed_maps not being read from the config file.
• Fixed issue #973 fluidterm crash on MacOS (Thanks @Alex-CodeLab)

v3.7.4

Fixed settings problem with v3.7.3

v3.7.2-pre3

Test release for cumulative fixes

• #953
• #955
• #941
• perhaps others

v3.7.2-pre2

This version fixes some potential crashes by restricting the amount of memory that the WiFi system can claim. Before this, if there is a lot of WiFi traffic, the WiFi code could use up so much memory for incoming packets that it starved FluidNC. That memory use is now limited to a safe amount.

Additionally, this fixes a problem with intermittent pauses when executing from WebUI, particularly when using auto-reporting.

v3.7.1

Bug Fixes

• Fixed SD card reporting units. GB was reporting as TB
• Fixed PWM duty calculation error.
• We got rid of the core dump message at boot. This showed up recently due to Espressif library changes.

Enhancements

• Leading and trailing space characters in config files no longer produce errors in most cases now.
• Added an extra probe called toolsetter. This probing now will stop when either goes active. This makes it easier to probe when you have an N.O. and an N.C. probe.
• The number of user digital output pins has increased from 4 to 8.
• 5ms switch "debouncing" added.

WebUI Features

• Browsers can now cache the WebUI for faster loading
• Probe function now uses the P parameter of G38

Note: Be sure to reload the WebUI (index.html.gz) if you are upgrading.

v3.7.0

Fixed the file reference issue with the install-fs scripts.
