You may prefer a product that has dedicated support provided by the vendor.ĭetails as known at time of publishing.

Support – some products have no support, and you’re reliant on the goodwill/knowledge of the user community.

3rd-axis capability – for some users, the ability to control a Z axis table or rotary via G-code can be important.

Quality of the engraved images – gray scale looks better than dithering, and 16 bit is much better than 8 bit.

Ease of upgrade (the technical effort and complexity).

The work-around is to use the K40whisperer software which emulates the proprietary G-code so that your K40 can be accessed by software other than MoshiDraw / LaserDraw / CorelDraw.īefore we step through available controllers in this K40 controller review, let’s be clear on what factors matter….

It runs an unknown propriety form of G-code, making it hard to work with.

It’s expensive for what it is – outdated technology.This simply means it can only switch on/off at one set power level, so you miss out on the improved images that gray-scale engraving brings It provides only dither-mode engraving.It has very limited control of cutting in corners, which is likely to result in burnt corner points.It’s just a motion controller which has not been integrated with the K40’s digital control panel for laser power.

It is the standard controller that ships with each K40 laser.
