K40 Whisperer reads SVG and DXF files, interprets the data and sends commands to the K40 controller to move the laser head and control the laser accordingly. K40 Whisperer is an alternative to the Laser Draw (LaserDRW) program that comes with the cheap Chinese laser cutters available on E-Bay and Amazon.

He was the first to enable free V-Carving for CNC routers and now he is setting the standards for free K40 compatible laser software.
Laserdrw 3 change power software#
I am a great admirer of Scorch and his excellent software solutions. Because I am happy that the following software is not in any way in competition with Mach I have posted this information as it may be of interest to followers of the thread. They do not use Mach3 or are even likely to use it in the future but they have come here to gain knowledge and information. Over the years this thread has been running I have been contacted by many users of the K40 Laser Cutter / Engraver. I have not fully tried this yet but it could offer a considerable reduction in the process time when laser engraving 8 bit images (currently using the S# command to control / vary laser output power). It is basically a way to output 8 bit numbers from within a running Gcode and having no noticeable effect on Axis Velocity or breaking the constant velocity chain. The interesting part, and the point of all this, is that Outputs# 1 to 8 could be interrogated by a simple controller (to convert the bit pattern to an 8 bit decimal value from 0 to 255) which could then be used to control / vary laser output power from within Gcode which is running at constant velocity. Obviously any combination could be set from 00000000 to 11111111. So please consider the following snippet of Gcode…Īt the instant the X axis moves the Outputs# 1 to 8 would contain the binary data 1 1 0 1 1 1 0 1 (assuming you are reading the bits from the same direction as me). M62P1 would turn on Output #1 at the instant of an axis movement and M63P1 would turn off Output#1 again, at the instant of an axis movement.Īs of Build 210 the Ethernet Smooth Stepper plugin allows for multiple instances of the M62/M63 commands to be stacked and operated jointly upon an axis (any axis) movement. Mach4 has the commands M62P# and M63P# (where the # denotes the Output# number) which both only operate, or take effect, consistent with an axis movement. Something that may be of interest to others…
