  1. Re: Two stm32f103 boards Firmware MOD-UPGRADE for laser etcher-cutter CNC 3D printer

    This project I have set aside for some time, I'm working on other projects that are more important currently. Ruibarbazul I see some differences in the pin assignments. I believe you are correct and...
  2. Re: Two stm32f103 boards Firmware MOD-UPGRADE for laser etcher-cutter CNC 3D printer

    we are working on it. but it looks like we can just generate a two sided PCB and correct the wires. sucks to have a DBL hat setup but at least it will make the olimexino usable as a grbl controller....

  4. Re: Two stm32f103 boards Firmware MOD-UPGRADE for laser etcher-cutter CNC 3D printer

    found some wiring issues for the OLIMEXINO and grbl
  5. Re: UCNCV4 usb cnc controller board with opto isolation and relays and offline functi

    You can use the tool sensor in more ways then one. An off set trick is to use a 1/8th 1/4 what ever bit depending on your tooling setup is. I like to use old broken bits. I cut or file off the flute...
  6. Re: Two stm32f103 boards Firmware MOD-UPGRADE for laser etcher-cutter CNC 3D printer

    New photos of the laser etcher and finished 3d prints. https://photos.app.goo.gl/1ejmwQjHGskbBvob9 . everything is working at its current design and minimum state of need. I'll be switching focus...
  7. Re: PWM signal SPD CTRL for laser etcher/cutter fan and compressor.

    I just realized that my pastebin is missing a "" } """ at the very end/bottom of the code. SORRY to anyone who was not able to compile it. Remember its written for an ATTiny85
  8. Re: PWM signal SPD CTRL for laser etcher/cutter fan and compressor.

    If anyone tested any versions of my code please give me a review
  9. Re: Two stm32f103 boards Firmware MOD-UPGRADE for laser etcher-cutter CNC 3D printer

    I'll post photos and details soon as I get a chance on the olimexino-stm32 ST-LINK header. thought the details are available as far as pinout etc.... in the form of a PDF manual.... My adapter...
  10. Re: PWM signal SPD CTRL for laser etcher/cutter fan and compressor.

    I have written a new version of code, I have not tested it yet but it should give working independent PWM signals for both the air compressor and the fans, pwm input signals. This weekend when I get...
  11. Re: PWM signal SPD CTRL for laser etcher/cutter fan and compressor.

    WORKING FINAL DESIGN
    Use my designs at your own risk they are with out warranty and I am not to be held responsible for any damages, injuries' or fire etc.... this is a DIY for educational purposes...
  12. Re: PWM signal SPD CTRL for laser etcher/cutter fan and compressor.

    This is just a TEASE, and YES I FREAKING KNOW the uC is a pic chip. I just used it as a heat wick while soldering the socket into place. I have one change to make to the board that I didnt discover...
  13. Re: UCNCV4 usb cnc controller board with opto isolation and relays and offline functi

    kmcfall48.... if you got it from amazon. regardless who the """" supplier """ is it should come with a license on what ever disk or media also shipped with it. You dont have to use the planetcnc ...
  14. Re: Two stm32f103 boards Firmware MOD-UPGRADE for laser etcher-cutter CNC 3D printer

    This weekend I will upload the pcb drawing and gcode files for the ST-link adapter board I built. And the GCODE files for anyone who is interested in building the board and has a cnc machine.
  15. Re: PWM signal SPD CTRL for laser etcher/cutter fan and compressor.

    final version controller built. No coding done yet. I will upload the final versions kicad build schematic/pcb and hand designed GCODE files for anyone with a cnc machines that can do pcb milling.
  16. Re: PWM signal SPD CTRL for laser etcher/cutter fan and compressor.

    Here is the gcode file in a zip file I could have etched the copper PCB but I chose to use my cnc machine. there are 3 files, the drill file the pcb traces file and the cut out file. all assume you...
  17. Re: PWM signal SPD CTRL for laser etcher/cutter fan and compressor.

    Ok I'm very glad I fell asleep early last night. I just discovered I forgot to add an opto isolator for the laser input. I should finish my pcb artwork and get it milled tonight. if I do I'll post my...
  18. PWM signal SPD CTRL for laser etcher/cutter fan and compressor.

    In a nut shell, I am building a custom controller for controlling upto two PWM devices with phase correction, manual speed ctrl adjust, and laser activity monitor function. I'll be posting my PCB...
  19. Re: Two stm32f103 boards Firmware MOD-UPGRADE for laser etcher-cutter CNC 3D printer

    nice work
  20. Re: Two stm32f103 boards Firmware MOD-UPGRADE for laser etcher-cutter CNC 3D printer

    swapping pins would be very easy. I have not had a lot of time as of late but finding a good location to do a simple trace cut and trace jump would be no problem. Though code adjustment would be the...
  21. Re: UCNCV4 usb cnc controller board with opto isolation and relays and offline functi

    nifty, nice work. And compact
  22. Re: Two stm32f103 boards Firmware MOD-UPGRADE for laser etcher-cutter CNC 3D printer

    Now that the HARDWARE mod has been finished. I'm looking for help from anyone that does STM32 coding. My over all goal for now is to get GRBL onto the stm32. I know there is stm32duino and I dont...
  23. Re: Two stm32f103 boards Firmware MOD-UPGRADE for laser etcher-cutter CNC 3D printer

    The BOOT0 mod complete and tested works wonderful.
  24. Re: Two stm32f103 boards Firmware MOD-UPGRADE for laser etcher-cutter CNC 3D printer

    Board LED tied to pin 9 PC1 active high. pin 52 PC11 is connected to the base of a 2A PNP SMD transistor which is connected to D+ of the USB port for soft reset and active low I believe, the other...
  25. Re: Two stm32f103 boards Firmware MOD-UPGRADE for laser etcher-cutter CNC 3D printer

    BOOT0 selection pin60. you must cut the trace which is tied to ground. setup a jumper and hot glue it down. If you load firmware that changes the boot method. You will need to change the jumper to be...

    I have accessed the chip with my ST-link setup photos to follow, something I have just learned by default you can read the stm32 after clearing the write/read code protection (CLEARING THE CHIP) just...
  28. Re: Two stm32f103 boards Firmware MOD-UPGRADE for laser etcher-cutter CNC 3D printer

    I'm taking a little bit of time tonight that I have a moment to build the ST-link header. I'll post a high detail photo later on when it is complete to show how to build the interface. to sum it up....

    If anyone can help post a schematic/PINOUT before I get to it for the BSMCE04U mach3 controller Please by all means. The OLIMEXINO-STM32 has full documentation being that its "DESIGNED " for...
  30. Re: Two stm32f103 boards Firmware MOD-UPGRADE for laser etcher-cutter CNC 3D printer

    If anyone is interested in my GRBL control panel I designed that is in my LASER ETCHER link of progress photos. post about it and I'll see if I can find my source files and GCODE files etc...... and...
