Brains Development / Re: Mach with Brains, smart enough for closed loop?

Hood,

How would you setup a gecko g320 to estop mach if the drive faults?

Thanks,Joe.

Brett,

Just watched it,im trying to do a compare of the encoder dro to the g53 position,can get it to turn on an output when it exceeds a set value,ex:output 2 comes on if the difference is greater than .005,but cant get it to estop mach yet.

As fate would have it im the guy that did the stepper with encoder setup with emc2 and 2 parallel ports.i just learned about mach brain last night.I have downloaded the latest version and presently working on getting a brain to stop the software if it gets out of position.This has already been done in mach with a macro pump,and more recently with a plugin for the rogers encoder board.I dont see why it cant be done with a brain.Vmax is correct in the fact that to be real closed loop at the software level it needs to be realtime,however this would still be a tremendous safety advantage,allow you to use the encoders as a dro when the motors are off,and help to avoid needlessly scrapping a part.Unfortunately I dont know how long it will take,im new to brains,any input is welcome.I have a machine here to test a brain if anyone has any ideas.

Thanks,Joe

General Mach Discussion / Strange G81 Operation in 2.031

« on: January 09, 2007, 09:47:38 AM »

Had a call yesterday from a friend asking me how to fix a problem with his g81 drill cycle.He stated that if you looked at the graphics in an iso view it looked like it was drawing a triangle.His program was a simple g81 with 4 holes in row.He also stated that if you changed to g83 it drilled ok.I checked his code,ran it here on the desk and it looked good,but I was using .028.Later I loaded .031 and it did what his was doing,immediately changed to .033 and it went away.Hope this helps anybody that has a g81 that draws triangles on the simulation screen.

Joe.

Was wondering if yall were gonna be at any other locations this year,York is a pretty good drive from Huntsville,Al.

Could you put your program up here so we can see it.Curious as to why its doing that,mine is working correctly.

Sounds great.My customer has showed serious interest in 1 of these boards,any idea how long before the plugin is available?BTW the shuttle express works fantastic.My customer has 14 late model mazak machines and 1 hurco with mach3 that i just retrofitted.Everyone that has seen this machine run is blown away including the mazak service guys.Keep up the good work.

Brian,

What will the difference be between the plugin vs the current macro pump that is used?

Thanks,Joe.

Being able to reset and the dro resetting to the encoder position would be a great feature.

Just finished a retrofit on a hurco machine center with geckos,us dig encoders,and a campbell combo board.This setup is running 250 ipm easily.The encoder card should be just as fast,its made by the same guy,Jim Cullins.His boards are top quality.
