I use Vcarve pro for my CAD and toolpaths. I will see if they have an A axis for laser on. I guess I would need a relay to go from 5V on an output to 12V for the laser. I do have extra outputs on my PMDX board that I could use.

Mach4 General Discussion / Add a laser to my CNC

This is probably a stupid question  ::)

How do I add a laser to my existing CNC. More specifically how do I activate the laser? I thought about doing it with a micro switch and when the Z axis reaches a certain point it provides power. I have a 12V light on the router head that is connected to a jack. I could use this. I am sure there is a more elegant way of doing this in Mach 4.

Check out the other auto tool zero thread. It worked for me.

ok updated to set z axis on probe touch

Code: [Select]
local ToolSetter = 15.7 -- change to your toolsetter height
mc.mcCntlGcodeExecuteWait(0,"G91 G31 Z-15 F40") -- change feedrate and depth to suit
mc.mcCntlGcodeExecuteWait(0,"G91 Z2 F40") -- change feedrate and retract to suit
mc.mcCntlGcodeExecuteWait(0,"G91 G31 Z-3 F10") -- change feedrate to suit
mc.mcAxisSetPos(0, mc.Z_AXIS, ToolSetter) -- set dro to height of toolsetter
mc.mcCntlGcodeExecuteWait(0,"G91 Z5 F40") -- change feedrate and retract to suit, use this Z rectract value for line 7
wx.wxMessageBox("Remove ToolSetter") -- remove if needed
mc.mcCntlGcodeExecuteWait(0,"G90 Z0 F50") -- move tool to zero,  change feedrate to suit

Thanks

I looked for tool height probing macro b on the forum and in the toolbox and did not find anything.

Any suggestions where I can find this?

I do it manually with a piece of paper. Would love to see auto tool zeroing working.

I can get G32 to work with my probing plate, but have not been able to get auto tool zeroing to work.

On version 8 of Vcarve the options are on the right side on the top of the toolpaths. (see graphic) Older versions put it under the work setup.

I would also put in home switches. M4 really likes to be homed before it starts. You then set your X=0, Y=0, and Z=0. above your workpiece. There is a button that reads Mach coord. if you click on this it will show you where the machine thinks it is located from the home position. The work offsets are where the machine thinks it needs to start for your work piece.
