Z probe for height map

1 comment

Hi,

 

I'm using a CNC2417 for PCB engraving and need to create a heightmap in Candle as there is too much flex in the board for a perfectly level surface. I understand that GRBL0.9 uses pin A5 for this. My assumption is that your control board doesn't connect anything to this pin on the Nano board (i.e. I can safely solder a lead onto it for the probe) - is this correct?

 

Thanks

For the sake others who are interested, I figured out that the A5 and Ground pins are broken out to a molex connector - it's the one directly above the low power laser connector (assuming the power button is on the left). The Ground pin is on the right and A5 is on the left - the height map function now works perfectly.

  • it is possible to have the print file of the carriage carrying the z axis motor. on my 2417 it was damaged after 6 months. I have the version with a larger motor. I have a 3D printer and I could print it directly.
  • Hello to everyone I am new here and a newcomer to CNC laser cutting world too. I have bought a CNC Laser cutting machine with a 15W laser which has a electronic board in a separate metal box, I would like to put a fan on this unit too; I am going to install the box on a special support near the laser head (the seller did not send any type of fixing for this part). Must I connect to control card fan plug or there is another free plug on the Laseraxe control board (CNCC Mini control board last model ). Thanks
  • Hello... I can't understant why all my step motors work oposite. What do i mean when push down button from programm the step motor go up and when push up the step motor go down. Exactly the same happen in all axes, reverse moving. Is any option- setting from the program where can reverse the moving? Or the bord is damaged? Best, Dimitris
