How to stop the spindle from turning????

Postby Warped Mind » Wed Sep 13, 2017 6:45 pm

vfd sized.jpg
Can someone help me that has knowledge with the Laguna IQ. I have purchased a diamond drag bit and I am having trouble turning the spindle off to use it. Laguna has been trying to help me but my machine is almost 5 years old and the vfd on my machine is different then the current model. Here is a picture of mine.

Thanks

So manually deleting the M03 command from the .mmp file doesn't work?

first line of code turns the spindle on.

I have a 5 year old IQ too.

you can create a new post processor by copying your existing PP (Laguna_IQ_HHC_C3D.pp)and call it something else like Laguna Drag.

edit Laguna Drag and edit the following area and delete what is red

+---------------------------------------------------
+ Commands output at the start of the file
+---------------------------------------------------

begin HEADER
"(Filename: [TP_FILENAME])"
"[N]M03[S]"
+"[N][XH][YH][F]"


save it and use Laguna Drag PP processor when using a Drag bit

I haven't tried this, but this is what I would try if I was trying to solve your problem

thanks for the responses, but both of you are talking way above my head. When I save a file to run and insert the zip drive into my handheld controller I am not aware of any way to access the g-code so to speak.

Your zip drive has the *.mmg files that are uploaded into your IQ.

with a text editor open the file that has your drag bit toolpath on.

The first line has the file name on it.

the second line has a text that looks similar this: N10M03S24000

N10 is the line number

M03 is the G-Code command to turn the spindle on

S24000 is the G code command for RPM

Just delete the M03

Save the file and load it on your IQ

In theory it should do what you want.

My second post allows your to modifiy the post processor so you wouldn't have to do all this editing on every file you want to use that bit on.

For all you G-code experts out there (I'm not one) Laguna IQ ignore spindle RPM command so leaving S24000 command in should not be an issue. I didn't want to delete the entire line not knowing how things work if you don't start on line N10.

Leaving the S command would most likely have NO effect.

The "N" line numbers is MOST controls don't do anything.

If it were me, and I am one of those "G" code experts - I would cut out the entire line.

I'm NOT a gcode expert.

If you want to keep the gcode line intact, why not just put parentheses around that line of gcode instruction as in (blah, blah, blah)? That turns it into a comment, and no action occurs. You still have the instruction if you ever want to change it back by removing the parentheses.

OK guys Warped Mind is not a computer expert so lets not overload him with options.

It seams that people who know way more about g-code than I agree my solutions will work. Or at least they didn't say I was wrong :D . Trying to be a glass half full guy today!

Warped Mind you need to find someone familiar with a text editor to help you through this process.

If you are going to be doing a lot of drag bit files then modifying the post processor (PP) is the way to go. Down side you would have to remember to switch back and forth with your "normal" PP.

If just a few drag bit files, then manually strip out Spindle On command.

Certainly someone in that firehouse has used a text editor before. Are there any local CNC clubs? Check Rockler and Woodcraft.

Thanks guys for all the input, you are correct I am not a G Code guy, the great thing about the Laguna, I guess Its great, is that when I finish a design on Aspire and output it to my zip drive and load it into the handheld controller, all I do is hit run and its off to the races. Great thing is Laguna even after all these years and advertised support time has expired they still stepped up and helped me get my issue resolved last night. They actually emailed me a new post processor named Drag knife, called me on the phone and walked me through the installation process. So Ohiolyons you were spot on in your assessment in creating a new post processor. It was just above my capabilities. Thanks again to all of you for your responses and help. Ill update this thread with my first successful drag bit project in the very near future.

Nice thing about G-Code is that it is VERY flexible and there are lots of ways to skin the cat. That said, the not so nice thing is that it is not so straight forward and there ARE many ways to do a simple thing. All the suggestions may sound contradictory. Also, different machines require different structural setups and sometimes different coding. To someone that does not work with it try to sort out postings and not know for sure what info is good or not, can be overwhelming.

I will applaud Laguna for stepping up to the plate the way they did - that is AWESOME

Glad you found a workable resolution.
