GRBL (the firmware in the controller) does do velocity smoothing on shallow corners, but for steeper corners it has to stop. This can be removed...
GRBL is the controller. You are thinking of the GUI, like OBCONTROL or bCNC or UGS, those just send the Gcode to GRBL and have no concept of...
The microprocessor used in the Arduino Uno has limited memory, and GRBL uses about 98% of it, there is simply no space to add backlash...
You only need 3 wires from arduino to each clearpath, ground, step, direction. Optionally you can also wire in the 'stepper enable' pin. Note...
which direction is it 'cutting'?
This is called backlash and is much easier to diagnose if you also tell us which way you were cutting, clockwise or anticlockwise, and indicate in...
Still where? Can you post a screen capture? I have just done a trial calibration and do not see the value I typed in repeated anywhere at all...
The stock GRBL post supplied with Fusion is not very good, we recommend using our OB post docs:software:fusion360 [OpenBuilds Documentation]
The machine needs to be 'selfaware' as to size and orientation and this means it needs to home to establish this knowledge. If the machine has...
That means you are running GRBL 0.9 which does not support jog commands. You need to flash GRBL 1.1, just use OBCONTROL to do it, much easier than...
and reading the wiki should be high priority Grbl v1.1 Interface · gnea/grbl Wiki
if you do this, remember to put a G4 P0.1 after any $xx=yy commands to allow/force GRBL to remain synced with the command stream. So you would...
Nope, not a post problem. I had Fusion v2.0.10.940 which processed with post version 1.0.27 just fine. Fusion updated itself to V2.0.11186 and...
not what I am thinking (-: the LASER is inverted, so he is using the TH input if it has such a thing, if it has onlyone input then it is acting...
seems like the PWM on the laser is inverted. ie M3 S1000 (5v on pin) turns it off, S0 or S500 turns it on.
You need a reference for both sides. I normally use the pins method and have one of the pins as the origin for both sides. If you have a...
what software? if Fusion360 with the OB postprocessor, then set the Z holdoff distance to -5 or -10 if -5 is not enough. This is always entered in...
No, these forums ARE the support, the videos and documentation above are the starting points. (and don't forget github.com/gnea/grbl/wiki to learn...
not that I know of.
your code will need to sit some where in the mouse processing chain so that it can capture all movements but also pass them along to the rest of...
