VB and the development of wizards / Re: Script for air pressure sensor

« on: September 21, 2011, 12:59:39 PM »

I don't think I did very much to brag about, a good portion of my buttons are just 'ideas' and don't work yet. I found machsreen and after clicking around for a while I had figured out enough to add buttons and what not, I'm not really interested in changing the visuls as much as adding useful functions and safeguards and cutting down on repetitious stuff like touching off multiple tools.

I missed that other message, I'm using the standard screen but I've modified it a bit, I don't think I've 'changed' anything, just deleted useless stuff and added some new stuff. Here it is if you want to take a look.

Here's a screen shot of my port and pins settings - maybe I gave you the wrong DRO? I got that number for the mach screen editor by clicking on the LED and looking at the properties.

Just tested it and it's not working. It's still going for a tool change with or without air pressure (switch/led is working).

Saving all the important info to do a restart from tool change seems to be the way to go, is it an additional script or part of the tool change script?

Gotcha, sounds like a plan. Got the wiring done, the way I have it configured is that when there is no air pressure the LED for Input 4 is lighting up. Checking the screen set, it is OEM-code 824. I've also attached my M6Start file so you can see what I'm dealing with. Thanks.

I just got my limit switches working on my cnc router. They're all wired in a daisy chain with the estop switch and in that daisy chain was the air pressure switch as well. I removed the connections for the air pressure switch because I don't want the machine to estop because of a pressure drop (the only critical need for air pressure is for tool changes). I think it would be better if I could modify the tool change script where the first thing it does is check the input I connect the pressure switch to, and if it's off (no air) then it would pause and a message pop up informing me to check the air, and clicking ok and closing the message would restart the tool change script, and if the air is on then proceed with the tool change and rest of the program.

Are there any basic flaws with this idea? At first I thought it would be pretty short and simple, but the more I comb though these forums/wiki/documentation and try and learn what I have to do it's becoming clear there is a very small chance I'll ever get this to work piecing it together from scratch. Any help or advice would be appreciated.

Well thanks for your time and assistance. I've been running the machine this morning and everything is working as it should.

My next endeavor will be editing my tool touch off script so that it touches off twice and compares the numbers against a tolerance value I can set; if it's over the set value than its stops and I get a message informing me of the discrepancy. I'm hoping it's been done before and I can find some code to work off of, I have no idea where to start.

Do you mean if I used a tool that was too long, or a z clearance that was to much, or material that was too thick? Wouldn't that be the case with any way you set it up? I say this because the program runs fine the way it is setup and programmed, everything works, I was just getting that warning. I think I have it fixed, I received an updated version of the mach3.exe and it seems to have taken care of the problem, ran two programs and no warning message. Thanks for the help.

Thanks, guess I will taking this thread to their forums then. As for the g-code running above soft limits - it does not. It looks that way because with tool and work offsets applied Z0 become the top of the spoil board/bottom of material, so besides the -.005 cut through depth, all the Z moves in the g-code are positive values. When the g-code returns the Z axis to 'home' it uses G53, disregarding the offsets and staying clear of the soft limits.
