Sounds like a race to the bottom. bCNC is a GCode Sender, not a controller. Grbl running on an Arduino is a controller (motion controller to be...
Using WiFi for the GCode Sender connection can work. Comm glitches are handled with TCP/IP resend (inherent in a telnet or webpacket interface,...
What controller are you using? Modifying Grbl to do what you are asking about is not an easy task and 8-bit Grbl is getting a bit long in the...
There are several board running grblHAL that have significantly more memory. Check out the Openbuilds BlackBox My response was silently edited...
Nope, F/H keeps the spindle running. I wish it didn't.
Try asserting the F/H input. That pauses motion but leaves spindle on. You might be able to output a F/H signal from your THC and then, when it...
Does Feed Hold not do what you want?
Are the compilers identical? Link options the same? Lots of things to check.
That is a taller order than you might think. Where did you get the .hex file? What source (and version number) was compiled to get that file?...
Probably the simplest way to do this is just edit the gcode and delete the first star section. What you want is canned cycles that allow you to...
Yes, but the Uno has plenty of drive capability (25 mA iirc), pretty low impedance. Not so for the 32 bit processors. I agree an op amp is better...
FWIW, a low pass filter gets you 0-5V from the Uno. No op amp needed. I don't quite understand the implications of the -5V aspect. Was going to...
Another approach might be to use pin 6 (0 to -5V) input of the TDA2088. You could put a low pass filter on the PWM output and then feed it...
The way to deal with material that is uneven in Z is to do a height map and apply that to the GCode. If you are using Grbl, a number of GCode...
Wow, that was a year ago... Thanks for buying the kit. I did get it working with a micro - actually several iterations: a Teensy LC based one...
G64 is unsupported. in the postprocessor section of cambam, there should be a way to suppress that.
Do you have $21=1 in Grbl? If so, then the BB is picking up noise. Set $21=0.
Right off the bat I'm going to say - Safety, Safety, Safety. Job one, two and three. I have been thinking about building a CO2 laser cutter for...
Would it be possible get a full picture of the dual CBeam? Or even better, a CAD rendering. I don't quite get how it goes together. [edit:...
I'm going to repeat my earlier comments but with more emphasis. [PSA Mode] This project is dangerous and unsafe as currently documented. The...
