Skips over M6

[ger21]

I couldn't test at my machine, but I stripped out the auto zero code from the M6, and you can change tools to greater than 96, and UCCNC will display the current tool as 101. Or 120, or 150, or whatever.
I looked through the macro as well, to make sure there's nothing limiting tools to 96. Anything in the M6 macro that results in tools not being changed will generate an error, and he said he's not seeing one.



Gene, try it with the tool # being 96 or less, and see if that makes any difference. I'll dig into it further tonight.

Can you post your profile?

I tried on another PC, in demo mode, and it runs the M6 macro every time, even with tool# 101.

Not sure if demo mode makes a difference, but I'll try tonight with my UC300ETH. I need to get another one for testing at my desk.

[Gene8522]

second tool is 101
uccnc goes up to 96!
if tool number is more than 96 it will be out of range and will not work

Not to argue, but using the same setup and tools (#) I cut a sign ( with a different name on it ) just before this one and the M6 worked and stopped to change tools.

[Gene8522]

I set up two short g-codes files using Aspire 8.5 and Aspire 9.5 to test the M6. I ran the test seven times using different scenarios each time. i.e. restart UCCNC between test cuts, changing the file between test, I even hide in the corner out of sight of the CNC so it wouldn't know I was watching. The results was............. The M6 worked every time even with a tool number larger than 100. So I'm at a loss at being able to duplicate the problem. As I said before this skipping of the M6 does not happen very often, maybe 1 in 10 times, but if I'm not watching it sure will ruin a project.

Here's one of the code files made with Aspire 9.5:

second tool is 101
uccnc goes up to 96!
if tool number is more than 96 it will be out of range and will not work

I think you are referring to 96 tools offset page?

Here are the files.

The only thing I can suggest is perhaps re-installing UCCNC ???
But I've never heard of this happening to anyone else, so that shouldn't really be the issue.

The M6 works every time for me with your files.

It looks like the post processors you are using are different in Aspire 8.5 and 9.5.
The file from 8.5 includes the first tool change, but the file from 9.5 does not. Is this possibly the issue?

gee......... I guess I'm just lucky. I sure hate the thought of re-installing everything.

I usually edit out the first M6 to save time running the cut, and I have already zeroed the first tool.
