General Mach Discussion / Encoder/MPG questions

« on: September 30, 2006, 05:38:50 AM »

I have been wondering what the MACH3 will do with encoder info.  I see the encoder/mpg section, but am not sure what it does.  I have encoders I want to use, there are A and B outs on each one.  Instead of dealing with writing code the count the quadrature pulses on the controller, are there ways to make use of the encoder inputs on Mach3?  If so, where would I look to study up on it?  Ideally I'd like to count the encoder pulses and compare to the actual output, and within some range have MACH3 stop  if the encoders are returning the same pulses.

Thanks

Yes that is cheap.   I made a decision today to keep my board in tact with the outputs, PS, connectors and encoders, and just get rid of their PIC16F84's and drop in my own micro.  I am going to use the Propeller by Parallax, which is an 8 x   32 bit 80mhz multiprocessor, one chip for all 12 motor outputs, 6 encoder quadrature inputs, 3 dir and 3 step. 

I have already tested out driving the motors from a breadboard, so I'll get it all done and make my own PCB and have complete control in the future.   I really appreciate all the help, but I have to bail on this manufacturers controller, it's been like prison.  SInce the hardware is in tact, it will get me by for now.

I think I want to now abandon their controller, I think it is dead and MAXNC says that using other softwares are damaging it.  Nonetheless, it doesn't run great even with their software now.  So it is time to punt.

I am looking at building my own Hbridges which would be simple, and running it in Step and Direction.  I am ust curious if I use MACHMILL.xml as the driver, and set my driver to receive the step and dir off the same pins as they are set up now.  The motors are 8wire uni, and although I have only used bi-polar, I think I may have an easier time with a home brew that their quadrature setup that has never worked right more than a day.

If anyone sees a problem with this thought process please let me know.

Here are teh files.  The OLD one that has finally bit the dust, plus your new one that at least will jog very consistenly.  Hopefully we can track down the area that is causing the  longer travel.

Hello

Well I tried to use the new driver today for the first time, and although it does jog th same as it used to, there are mysterious problems.  The Z axis raises up around 3 inches whereas the code tells it .07 rapicd plane.  Then, when it heads to its first destination, it ges so far it hits the switch, but it should only travel an inch.  I tried to upload my Maxnc xml but keep getting an server error that the site is exceeded quota.   I will try it again tomorrow.   I went back to my old driver just to try to get through the day,  6 hours+ and not even one cut made.  Your driver seems to jog very consistently so I am desperately hoping we can solve the issue with the travel being far off.  I went into motor tuning and set it to 200 just to see what happened.  It jogged slower, but still went too far over where it should have in travel.  I am about to print your file and my old one to look for where the problem may be.  Thanks for any suggestions.

The first one is the most reliable.  Test 1 is not running most if the time, Test2 has a better ratio of run to fail, but the first is very good odds.  I can work with this no problem.  Thanks again for all the effort, that is a life saver.
