I’ve bought used K3020 40W laser but there is an issue with Raster Engrave. I’m using K40 Whisperer. Please look at the pictures below. I’m trying to engrave SVG but when laser moves from black to black, it is not decreasing power of beam while on white/transparent(I’m 100% sure it is transparent). The power supply and tube are 100% new. I’m sure that the .svg is correct too because recently it worked good with this same svg and the same settings in K40 whisperer.
The $32 mention is for GRBL based controllers which the M2-Nano controller in your machine is not. From the picture it appears you do have ON/OFF control with K40Whisperer so that’s a start. Your subject heading might be a bit misleading if this only happens with raster engravings and your machine+K40Whisperer is working fine for vectors(ie it really is turning the laser power on and off just not inside very small raster engravings)
Does that same thing happen when you scale up that image to something like 5cm across? Asking because there are settings around accelerations but with such a small image you might not see the exposed.
I don’t have K40Whisperer running but I would look at the preferences/settings to see if there are settings for what to do at lines of the raster, at DPI / resolution, etc.
Thank you for your reply. To be honest I didn’t expect that someone will answer me and already bought new M2-Nano controller. It is still being delivered.
And sorry for the misleading. There are a lot of glitches with this machine so I did my best just to generalize my question.
It happens not only with Raster Engrave, but with Vector Cut and Vector Engrave too. The vector cut and engrave by itself are working good. But When laser is moving to a point where it has to start cutting or after finished, the laser is not OFF. It always burns its trace.
Yes, I checked different images big and small and the distance between black spots was ~2-3cm, the result was still the same.
K40 Whisperer has only these settings. I always used them as is by default.
and one more behavior which I found out. The beam is turned off on demand when moving in Y axis direction, but it is not turned off while moving in X axis.
So the software and controller has laser control( can turn the beam on and off ) when the motion is in the Y direction but any movement in the X direction there is no beam control? This is a CO2 laser so it’s not as iff the laser control wiring is on the laser head as in the diode machines… So that’s not likely going to be a wiring problem. odd indeed.
And generalizing and not stating all the facts just wastes everyone else’s time. Nobody here is paid to help so the least people can do is spend some of their own time and be thorough.
