Awesome, looking good! Yes woods with distinct hard/soft parts of the grain can give variation in burn depth/darkness, so that is not unusual....
What is the PWM currently set at? If it is running too high, then 100% on should still be full power, but other settings would appear to lose...
If the laser only comes on when S1000 is sent to drive it to 100%, then it could well be the PWM, as at 100%, the pwm line is on all the time and...
It may possibly be that the PWM frequency is too high, but it may also be that the pre-programmed file is doing something that fluidnc or the...
Fluidnc does odd things with the $10 and other classic GRBL commands, especially the earlier versions of fluidnc as all the settings are handled...
Yes the convention is for a negative coordinate system with the Machine Coordinates of X0 Y0 being the top right-hand (and Z0 being the Z axis as...
With a feed rate of 1000mm/minute for a 1/4" bit (and 10krpm), I usually use a Z plunge rate of 200mm/minute, but it does depend on what the...
Yes 1/2" deep is getting tricky to clear the debris out of the slot with an 1/8" bit. I have slotted a fair bit of 15mm thick (0.6") plate with...
For the 1/8" single flute, the numbers Alex gave of 10krpm, 500mm/min ( 20inch/min) and 0.5mm DOC (0.02 inch) are a good place to start,...
EvanH submitted a new resource: Milling Calculator V1.0 - spreadsheet for feeds, speeds, tool deflection and milling power There are a number of...
There are a number of spreadsheets available that calculate the chip-loads and surface speeds, as well as estimating the cutting forces and bit...
Thanks Peter, will do.
The 'depth of burn' is determined by the energy delivered to the surface, which is power times time. For the cnc, that translates into both the...
Peter, yes you are right the screens should only be grounded at one end so it is excellent news they are floating on the BB, and as you say, the...
As Peter says, removing grounds on power leads that are put in place by manufacturers should not be done. I have moved to running my machine...
The first device may work, but looks to be 'over specified' for the data rates needed. The cheaper alternatives like the one in the second link...
I have not used cncjs, but yes the macro you have created (and I assume a 2nd to switch back) in cncjs looks just as useful for switching the...
I have just run up 3.7.6 on my test rig, and the macros work ok. One thing to check is that when you do: $LocalFS/List to list what is on the...
V3.7.6 is older than I tested on. I have a fluidnc test-rig that I checked out the file operation on, and will install 3.7.6 and check to see...
