    Re: troubleshooting non linear motion on axis

    It seems that moving from 10 to 20" and from 20 to 30" are equal in distance and that the move from 0 to 10" if off.
    I suspect you have a back lash problem (play) Move from 0 to -1" and than back to...
  2. Re: digitizing software for GRBL/UGS arduino system??

    There is very little to find even YouTube and Google show only one video. So you have to find out your self how it is working.
    The result is a map of X,Y,Z points. That is a 3D mapping.
  3. Re: digitizing software for GRBL/UGS arduino system??

    UGS has an option to probe a height map and export the data to a file. It is not fast but it runs unattended.

    Re: Arduino / driver issue

    If the motors get hot, the wiring of the stepper motors is OK.

    If the motors get hot during running the problem is the step signal because the motors are enabled. The motor shaft is not locked...
  5. Re: 5A integrated 3 axis TB6600 cnc controller

    XS = X step pin
    XD = X direction pin
    XL = X limit pin (probably)

    NC = not connected pin, you can ignore these pins
    GD is ground pin, you probably only need to connect in GD pin

    Pm = PWM pin...
  6. Re: Feed Hold with grblHal Arduino Due not working

    You probably have, but did you uploaded the new configuration to your board?
    To be sure, you should change the version and check if the uploaded version matches your setting.

  10. Re: How to convert parallel port to USB in 90's CNC machine

    Craig,
    The OP wants to update the PC and needs a new (USB) controller.
    You are right about points 1,2,3 but to connect a new controller, the pin out is needed.

  11. Re: How to convert parallel port to USB in 90's CNC machine

    The "easiest" way would be opening the box and following the wiring.

    If you have a working system, you could also monitor the signals at the parallel port pins using an oscilloscope. Start by the...

    Re: Looking for feedback on GRBL based systems

    Why, because for hobby use, a mach3/4 board and license can be quit expensive, especially if you want to use a "modern" PC running a modern Windows version.

    Re: Looking for feedback on GRBL based systems

    I am not familiar with that controller or the NCnet lite software but:
    It could be you are transferring the data to fast and are flooding the controller buffer. To avoid flooding the buffers RS232...
  19. Re: Testing Basic Arduino motor wiring for new build, without breakout board

    If the driver is enabled, the motor can't be turned by hand. An enabled stepper motor can get hot when it is not turning. For that, most drivers have an option (switch) to reduce the current when not...
  20. Re: Testing Basic Arduino motor wiring for new build, without breakout board

    Grbl 1.1f is the latest & stable version and running flawless on thousands of uno's.
    Updating the IDE should make no difference, grbl doesn't use any of the Arduino library's. The only thing that...

    Re: China newker 1000 series servo gear ratio

    After the first move to -0.3 mm, the change in position equals the change in move. So the settings are OK.

    You have backlash/play/tilt in your Z-axis resulting in about 0.08 mm backlash. Check the...

    Re: 1419 cnc spindle upgrade

    That would require more than just a top quality bearing. Your spindle and collet should also be better than 5um and that is not achievable price wise and not using my hobby tools.

    Re: 1419 cnc spindle upgrade

    I have checked a lot of PCB milling videos and the best result are those who use a fairly heavy (800W +) router. That probably is caused by the bearing quality heavy routers have. There is a pcb...

    Re: GRBL and Gecko G540

    5V output to the VFD is no problem. You can set the VFD to run at full speed on a 5V input signal.

    The Arduino output is a 5V PWM signal. Your VFD probably won't like this signal. I am going to...

    Re: Bad cut on angled lines and arc

    If it is not the ball screw, bearings, rails, or resonance, and the problem is most visible in the 45° angle, than it can be caused by X and Y steppers not running synchronously.
