    Re: Chinese 150w Laser Not working correctly

    You could run a test and swap the two drivers between the X axis and the Y axis and see if the problem moves to side to side instead of front to back. This would let you know if you have a bad...

    Re: China 3040 parallel port

    This board has a tool setter input available, this is all you need to do is configure it for that port/pin. The axis inputs are clearly labeled, very easy stuff.

    Re: Chinese 150w Laser Not working correctly

    Clearly anything burnt would be suspect. The loud noise will moving seems to suggest an issue with the steppers, does X or Y axis work without unusual noise?

    You should post some photos of your machine, but the simple answer is YES. Most of these older machines need to have the electronics swapped out for something current. Depending on the Servo Motors...

  14. re: Mach3 Board only has 4 input pins how to connect Limit and homing when 3 used?

    If you don't have a dedicated estop input you need to use one of those input pins for that item. You can wire two home sensors to the same input, because the machine only looks at them one at a...

    There are lots of cheap Chinese self contain cnc controller with a display that can do 3-4 axis, that usually cost around $100. Now you just get one of those and configure one axis, and that will...
  17. re: Mach3 Board only has 4 input pins how to connect Limit and homing when 3 used?

    Use the first three inputs for X,Y,Z home sensors. Now put all of the LIMIT switches in series, so if anyone get bumped it stops the machine, all of these will go into the four input pin.

    Some...

    Re: Motors don’t back home switches.

    I have had this happen in Mach4, check to make sure the home switches are enabled and configured correctly. This is definitely a configuration error not hardware

    Re: Benchman 4000 CNC - Homing Problem

    Check your software, pretty much all software CNc controllers require you to home the machine before you start. On the estop make sure you don’t have more than one or a door switch

    Many thin sheet aluminum are not 6061 and are very gummy. Reduce your depth of cut to less than half of diameter of cutter. Wd40 can help as a coolant and help keep it from sticking to cutter

  30. Re: Cnc machine sometimes ignore limit sensors

    Just because the LEDs blink when activated on each limit does not mean the output transistor in the sensor is working. Look for a input/output test page and ensure the inputs are actually switching
