To all that have asked for the script, I have posted it below. I just realized that my website is actually down currently and am working to get it live again. As I mention in my video, the "PlateThickness = GetUserDRO(1151) 'Z-plate thickness DRO" line can be replaced if there is no DRO input. Simply measure your own block thickness and change the line of code to read something like: "PlateThickness = 2.00" for a 2" thick plate. Copy and paste from here: CurrentFeed = GetOemDRO(818) 'Get the current feedrate to return to later PlateThickness = GetUserDRO(1151) 'Z-plate thickness DRO If GetOemLed (825)=0 Then 'Check to see if the probe is already grounded or faulty DoOEMButton (1010) 'zero the Z axis so the probe move will start from here Code "G91 G4 P2" ' two second delay Code "G31 Z-1.0 F5" 'Z goes down a max of 1.0 at 5IPM While IsMoving() 'wait while it happens Wend ZProbePos = GetVar(2002) 'get the axact point the probe was hit Code "G90 G0 Z" &ZProbePos 'go back to that point, always a very small amount of overrun While IsMoving () Wend Call SetDro (2, PlateThickness) 'set the Z axis DRO to whatever is set as plate thickness Code "G4 P0.25" 'Pause for Dro to update. Code "G90 G0 Z3.0" 'retract Z to 1.0 inch Code "(Z axis is now zeroed test)" 'puts this message in the status bar Code "F" &CurrentFeed 'Returns to prior feed rate Else Code "(Z-Plate is grounded, check connection and try again)" 'this goes in the status bar if applicable Exit Sub End If Thanks for looking. Please post back with questions.

+rhfabrication HI, can you tell me, When you set up the probe in the inputs window. By default it said PORT 1 and you said to change it to "8" ?? (I cannot see the numbers since the video has low Res. and cannot distinguish.) So you changed that to port 8 and it worked?? BTW: the reason it does not work on PORT 1 is because the computer only has one LPT port (port 0) for Port 1 you would have to Plug in a Card in the PCI slots with a second LPT port that will be Port1 but you only do that when you have 5 or 6 axis to operate. Normally the existing LPT is good for 4 axises.

Mach 3 will only.move in one unit system at a time. the g code has no units so to speak. if the program is made in metric units, you need to make sure Mach is set to metric. otherwise a movement intended to be 3mm could move 3 inches is the system is in inches mode. Does this answer your question?

Just found your video and starting to look at how to save tools to mach 3. Question if your tools are standard sizes but you use them in metric gcode sometimes how does that work or does it make a difference when saving them to mach3? Say the Tool 3 is saved as a .125 diameter and use it as .125 in a program but another program you are running a 3mm tool size but use the .125 instead of a 3mm does it make a difference to mach 3 as long as the gcode says i am running a 3 mm tool?

Question for you. How do I do this if my Z surface is machined already? I have the touch plate functioning with the auto tool zero but it's useless because by the second tool I have no reference point to put the plate onto.
@rhfabrication

I always set the table to Z0. This way, you can always reference the table rather than the workpiece. I prefer this method anyway since it doeant rely on precision workpiece thickness. I reference each tool to the table at every tool change.

@@soorenaaslani7491 I see, the whole table is covered so no touch off point left. At that point, the only way would be to have tool holders with preset offsets. Of course a regular router wouldn't have that. Best I can think is to leave a spot unmachined to have a reference point or a known location to reference from.

@@rhfabrication no I'm not talking about the table being covered. You said you touch the next tool off the table how are you doing that with no Z reference? If tool 1 is 1inch let's say and tool 2 is 1.2 inch how do you tell the machine that? You would need to make sure your second tool is exactly the same length as the first so I'm not getting how your doing that with the probe off of the table. If you have a z surface then you can just probe your tools off of that and they will all be equal distance from the surface of the part but with the table that's impossible

@@soorenaaslani7491 I always have room to the table to set the zero to the table. If theres no table left, you have to improvise a way to have a known reference height. Could make a jig that straddles the table maybe from underneath and sets a known z height.

can you please help me ? no matter what I always get a 2mm difference between zeroing and going to zero, ie. auto tool makes contact, reverses up a bit and when I press gotozero button it goes 2 mm below the probe height, any idea what might be causing this ? Z axis is calibrated

What is the plate thickness variable set to and what is the actual thickness? it sounds like going downward is a positive movement on your machine maybe? In that case, you would need to change the code so that after it touches, it goes negative plate thickness rather than positive which the code does by default.

rhfabrication thickness is default from your script, 2,000 is this inch or mm ? Probe is 20,07mm high. Actually I've explained the problem wrongly, I believe that when I press gotozero it should go all the way down to probe base height but it doesn't it goes only 2 or 3 mm below contact plate on top, I tried changing thickness in script to 20,07 or .0790inch and there's no difference. Btw if I press play on script editor it moves Z downwards so it is working

MentallFloss The code will execute in the units you are currently using I think. I use inches for mine. If using mm, you may need to make a couple of changes. first, set the plate thickness to your thickness of 20.07mm. Second, there is a line that allows it to travel up to 1 inch downward before it errors. That is too close for 1 mm I think. Try using 25th for that. All else should be fine as long as descending is negative which it sounds like it is. Again, I don't run mine in metric so I can't be sure but these steps should fix the problem. You can always private message me also. I hope this works. Please let me know. Thanks, Richard
