Laser PPI

Under development. Adds 3 M-codes for controlling PPI (Pulse Per Inch) mode for lasers.

  • M126 P- turns PPI mode on or off. The P-word specifies the mode. 0 = off, 1 = on.
  • M127 P- The P-word specifies the PPI value. Default value on startup is 600.
  • M128 P- The P-word specifies the pulse length in microseconds. Default value on startup is 1500.

NOTE: These M-codes are not standard and may change in a later release.

A description of what PPI is and how it works can be found here.

I have a customized version of ioSender that I use for my CO2-laser, this has not yet been published but I may do so if this is of interest.

Dependencies:

Driver must support pulsing spindle on pin. Only for processors having a FPU that can be used in an interrupt context.

Laser coolant

Under development. Adds monitoring for (tube) coolant controlled by M8, configurable by settings.

  • $378 - time in seconds after coolant is turned on before an alarm is raised if the coolant ok signal is not asserted.
  • $379 - time in minutes after program end before coolant is turned off. (WIP)
  • $380 - min coolant temperature allowed. (WIP)
  • $381 - max coolant temperature allowed. (WIP)
  • $382 - input value offset for temperature calculation. (WIP)
  • $383 - input value gain factor for temperature calculation. (WIP)

WIP - Work In Progress.

Dependencies:

Driver must have at least one ioports port input available for the coolant ok signal. An optional analog input port is required for coolant temperature monitoring.

LightBurn clusters

Under development, experimental.

Add #define LB_CLUSTERS_ENABLE 1 to your my_machine.h to enable.

The plugin unpacks the clustered S command from the input stream and deliveres standard gcode to the parser.
