I'm interested in level 3 - which (for me) is the answer to backlash and the like.

I can't imagine any controller at any level being the answer to backlash. Backlash is simply a mechanical problem. No controller can truly fix anything it doesn't have control over (which is the definition of backlash).

Just my 2 cents.

I would write the PLC ladder to look at a register to determine position to go to. Then in your M6 write the selected tool to that register.

Then write a 1 to another register to tell the PLC to start a tool change (it already knows what tool to go to because you just told it). This is the "go to work" signal in the PLC. The PLC will watch for the status of this register every scan.

Have your PLC do everything needed to change the tool. Get this working first. I have used a program named Qmodbus to read/write to the PLC for testing. Until you can do this, no reason to have Mach and the PLC talking to one another. You write the tool number to the register, then set the go to work bit to 1. The plc does all of the tool change then sets that go to work bit back to 0.

Once the tool change is complete, the PLC changes the go to work register back to 0 that started the PLC doing the tool change.

Mach will be watching this register and once it comes back as 0 (it can only == 0 after the PLC sets it to 0 because you just set it to 1) the M6 ends and Mach takes back off running your Gcode.

Think I remember reading and writing to C registers in the click for the stuff the PLC and Mach needed to be able to read and write.

I'm confused. The title of the post is "Manual touch plate probing after manual tool change". What is there to automate through script?

I know you might be able to do stuff like this with Mach3 but it has never been a good idea.

In Mach 4 you use Lua and the PMC. I don't hear a lot about people using the PMC but I just was able to connect 6 physical buttons on my lathe retrofit without know how to use LUA at all. LOVE IT!!!!!!!!!!!!!!!!!

Good on you Mike, that's awesome. Also a very good point I did not mention either. But you also either already knew or had to learn ladder logic. The question for the purpose of this topic is......... (and this is for everyone reading that wants to play along, not necessarily you Mike).

I know better but for arguments sake lets say you did not already know or understand ladder logic and had to take the time to learn it.

Would it be your fault for not already knowing ladder logic?
Would it be no ones fault and just part of the learning curve and even enjoyable as part of your choosen hobby?
Would it be Mach4s developers fault for providing the tool that gives you that option in Hobby?

If the answer you come to is option 3, let me know what options and/or features you think we should disable in Hobby. Or maybe we leave them in and it just helps us determine what questions to ask in a litmus test to determine if you really are a Hobby (realize doing your customization may take considerable amounts of your time and effort) or Industrial (wanting customization but don't have the time to do it myself but also willing to pay for it) user.

If Mach4 Hobby isn't considered Hobby material I'm sure we can make adjustments to fix that.

there is a development version on the FTP that may work better for you if your interested in trying. Version 4.2.0.3643
Thank you so much! You're my hero :)
Looks like 3643 works again (as 3485 did before). So only 3633 fails on XP

Well, don't take me wrong - I only used m4 with the screen editor as I don't have a working cnc yet. So I can't say if it will fail on real work. But at the moment I'm happy, that I can continue working on my screens :)

Reinhard, there is a development version on the FTP that may work better for you if your interested in trying. Version 4.2.0.3643. If you do, let me know how it goes. The only way i will ever know how something works in XP again is to hear about it.

You're probably right Brett.  I had the preacher with me.   ;D

I got to go on that one.  ;D

If there was a button in my new self-driving car that said "Take me to Church", I wouldn't expect it to deliver me to the whorehouse. Smiley

I wouldn't expect it to but if you ever get one that does just that let me know. I want it. It is obviously capable of reading minds.  ;D

I think you are about as plain and accurate as possible Craig.

I would also like to point out that your statement..... "but as soon as you want to customise your machine the effort required goes up dramatically" is true for almost any I know of if customizing is even an option.

The question is rather thought provoking. A hobby is something one does for personal  pleasure for whatever reasons and the reason need not make any sense to anybody except the one enjoying the hobby. The level pursued, time spent enjoying it, choice of activities associated with the hobby provides an arena to satsify the individual. So the answer is yes..... Mach 4 is hobby material and is just one part of CNC.

Exactly Rich. That's it in a nut shell. I would like to emphasise ONE PART.
