Tool touch off problem (Resolved)

[marks3465]

I'm trying to run a simple touch off mac mfunc6. I got it off this forum from a post titled tool setting options for routers and mills. Everything goes as written except my Z axis going down and touching my conductive plate. My Z never starts down and just goes back up as though the mac is done. I set everything up using Keith's video on touch plate and probe setup. I'm hoping that someone has run into this before. Again I followed every step that's in the Centroid PDF and Keith's video. Everything else works great pertaining to the other functions of my cnc router. It is a CNCRP Pro. I'm away from my machine but will be able to post a report tomorrow.

Did you try this first?:


Setup Tool Touch off Device in the Wizard:

What is the state of the touch off plate prior to initiating the sequence? I would think it is tripped.

I thought the same thing but when I checked using alt I, it's not tripped. I can run the built in PLC provided by Centroid like Kieth is using in the above video works just fine. When I try to use Scott's zero touch off mac. my Z never goes down to touch the plate. What ever height my Z is at is what the mac sets to zero.

The M6 macro that you have chosen does not include any probe moves (those would be, for example, M115 and M116).

It looks to me like that macro intends for you to use the option of jogging the machine during an M0 or M6, to manually jog Z down to the work surface after you load the new tool.

Also, I see that you have "ToolTouchOffTriggered IS INP7" in your PLC program, but you have Machine Parameter 11 set to a value of 6. At least one of those is not correct.

I changed the param 11 from 6 to 7 and saved it. Do you have a recommendation of a mac. that would work? Thanks again for you help.

You are mixing using the Wizard and going into parameters. This is not recommended unless you are directed to do so....just saying...

Use #2 macro for 4.14+ at the beginning of that topic where you got the macro. It works exactly as described. This one with automatically probes down after you manually jog over the plate. If CNCSNW is correct that you chose the wrong m6 macro, the one that doesn’t probe down for you.

Thanks for the info I will check it out.
