I'm pretty much done. I wrote a small program for a second Arduino which measures the pwm from grbl and writes a value to the shift register. grbl...
Indeed. This information is not provided alongside the hex image...
Ok. Plenty of scope for differences depending on, er, things. eeprom.c:#include <avr/io.h> eeprom.c:#include <avr/interrupt.h> grbl.h:#include...
The hex file and sources are from GitHub: Release v1.1h (2019-08-25) Release ยท gnea/grbl There's a hex file and zipped source at the bottom,...
Ok. Since this is the place to ask questions, how can I compile grbl to match the released hex file? I have downloaded the hex image:...
Hello again. Just thought I'd post an update. Thank you for the discussion and helpful suggestions so far. The key point for me was to learn that...
Ok. I've removed the microcontroller and soldered wires to the STEP/DIR pins on the stepper drivers. And a ground. If I can control one motor I...
Thanks for your comments. Yes, I was going to "steal" the spindle enable and spindle PWM pins. I only need two. Regarding the code, once the...
In case anyone is interested, the manual can be found at the download link on this page: JEULIN - Minifraiseuse 600 CE : Manuel (1999) The...
Yes, thanks for your comment. I have one of those. It is a PWM to voltage converter. 5V PWM signal in, 0-10V dc voltage out. Needs a 12V power...
...and this is why I am here. Thanks for a swift reply with a high level of technical insight! Excellent. Thanks for the suggestion, although it...
Ok. Since this is the place to ask grbl CNC questions, here is my question. It's more like a discussion than a question, but I'd be very...
