  1. Re: Why no Z travel when cutting thicker material in multiple passes?

    FWIW, I had an engineer friend explain the problem and why subsequent passes are not refocused.

    If you focus lower on a subsequent pass the walls of the trench left from the earlier passes would...
  2. Why no Z travel when cutting thicker material in multiple passes?

    Total laser newb here, but I have been doing some initial research to possibly build a diode laser capable of cutting 5mm ply. I've built CNC and 3D print machines, so I am familiar with the...

    Re: Super-PID new low-cost router speed controller

    I’ve cleaned the eye off and not had an issue since; but I’ve only run one job so it’s too early to tell. I have a Bosch 1617, so the sensor is through two separate plastic shells. Not much dust in...

    Re: Super-PID new low-cost router speed controller

    My SuperPID works well enough and has definitely improved my hobby machine. But occasionally it will suddenly go full open (max RPM). After a second or two it will fix itself. It is seemingly random....

    GRBL-Mega-5x/Ramps1.4 + SuperPID

    This has been a long journey, so I hope my experience helps others.

    The first issue with this combo is that SuperPID reverses SPINDLE ENABLE from what Grbl (and most others) expect. You have to...

    Re: Super-PID new low-cost router speed controller

    The VS and POT are jumpered together, per the instructions. There is nothing connected to the P5 terminal. I still read a voltage on the PWM terminal.

    Are you suggesting the VS and POT should NOT...

    Super-PID new low-cost router speed controller

    Thank you, but It is called a RAMPS 1.4 shield for the Arduino. That is short for “Rerap Arduino Mega Pololu Shield”. It is actually quite a popular and established controller. It is used on...

    Re: Super-PID new low-cost router speed controller

    I spoke too soon. It turns out the grounding I've done, at least so far, hasn't solved the problem. It appears that in my exhaustion trying to problem solve this I connected the SuperPID's PWM...

    Re: Super-PID new low-cost router speed controller

    Re: Super-PID new low-cost router speed controller

    Since the analog potentiometer seems to work in my set up, I am considering filtering the PWM signal with a DAC. It seems that the SuperPID was made with an analog input in mind, and I can't really...

    Re: Super-PID new low-cost router speed controller

    The Arduino is only a microprocessor, not a single board computer like a Pi. It functions more like the Gecko G540. The Arduino is powered by the +5v wire of the USB cable connected to a PC. It is...

    Super-PID new low-cost router speed controller

    Yes, this is a brand new v2 unit I received a week or so ago from them.



    Yes, this is how I have it connected.

    I am using GRBL 1.1 Mega-5x...

    I wanted to run a couple of jobs with the limit switches disabled to be sure. But it seems to be the issue. Frustrating, because I do not know how to harden the switches against RF interference...

    Random e-stop and limit switch UC100

    The capacitor did not solve the problem, but I don’t know if I did it right. I used the 10000pf one. I placed one leg of the capacitor in the pin 15 terminal and the other to ground. The actual...

    Re: Random e-stop and limit switch UC100

    I have some 22000pf, 10000pf, and 4700pf . Does the capacitance matter? I am connecting the +5V and ground for the e-stop pins (in my case 15), right?

    Random e-stop and limit switch UC100

    I am having random e-stop detected mid program. Sometimes it will happen every few second over and over. Sometimes it will say a limit switch, but that is less frequent.

    Why? I notice that is increasingly the way the hardware is going, but what is the advantage of Ethernet over usb?

    Re: BOB recommendation for 36V system?

    Because it is wasteful of money, electricity, and won't fit in my enclosure.

    Re: BOB recommendation for 36V system?

    1) No, the BOB is plugged into a wall wart for the 5v.
    2) The c-10 lasted about three years, but the Chinese BOB only about one.
    3) On the c10, one axis just stopped sending signals. The Chinese...
