Re: stepper stall (to Art)
Isak Levinson
I tried r1.0 and I'm sorry to say that it has the same problem.

While this is not overly fast, it may be fast to tell me what I need to know.

Re: feedrate overide for plasma
Scot Cameron
Art: my codes are written with G1,I have noticed that
if i use a smoother raster to vector conversion the speeds will increase with no problem,it seems to me that there are to many codes for so little axis movement,it is as like consatnt velocity is off,if i draw a simple square in cad,i can execute it as fast as i like,must be the g code conversion.I will run mach 1 tommorow and try the same codes on there.

Re: Constant velocity/Exact stop

Hi Art;
I have been using Programmers File Editor on Mach2 all along. Great editor for loading large files > 10meg. I checked logic page and path to editor was right. I clicked on browse and reselected editor. Editor now works again--- mysteries of windows again. Thanks for all your help. Bob Harvey |

Current R1.0 just uploaded has the toolchange bug repaired. Only one pressCheers Art - I'll give that a try in the morning. Has it got the fixed Mach2.sys file as well? I don't think there was a missing pulse - scopes still on it. I think what happened was initially spindle was turning so slow it stalled, maybe with the sensor uncovered. Sensor is a gap type, focussed by design. There's a disk on the spindle which runs in the gap, it has a narrow radial slot that opens the beam - it's not adjustable and is the same one that worked with the old controller for years. I have another identical brand new one and have replaced it with no improvement. Something was happening with the double clicks, maybe the speed was misinterpreted - I noticed a couple of weird things with other files too. Tomorrow will tell. -- Steve Blackmore |

Now having some trouble with having my editor come up when in Mach2. Make sure that the editor is pointing to the right program location in the logic settings. I usually use notepad, some other programs have trouble with command line tranfering of the file name. Its something I meant to fix so that wordpad could be used. Thanks, Art www.artofcnc.ca |

Re: Constant velocity/Exact stop

Hi Art;
G61 & G64 now work as expected on my machine. CV can be toggled on and off in the same program. Also when G61 or G64 is entered on MDI screen it now toggles the state screen settings. Now having some trouble with having my editor come up when in Mach2. Will check out some more and let you know if it's a problem. I have been lirking lately as you've been so busy and I didn't want to bother you. Thanks for the quick respounce. Back to lurking Bob Harvey |

Current Spin Count 4763 5440 ->11128<- 5305Normal Spin Count 2965 3007 2864 2884 Spin adder 2521 1828 701 2542 Thanks , looking into it. That third reading indicates a missing pulse. I had the same thing for awhile, it was my sensor being not sensitive enough where it was pointed. You can see its double the time for that rotation. This cannot be fluke. A pulse went missing and doubled the rotration time making the program think the spindle had slowed to half velocity... Looking into the rest. Thanks, Art www.artofcnc.ca |

Re: Constant velocity/Exact stop

Bob:
( And Izak). CV had a major problem. It is fixed and can be downloaded now in r1.0. Changing between G8 and G9 ( or G61 and G64) could be ignored under certain circumstances. (This included backlash) . It has been repaired and uploaded. This one was nasty, stareing at me, yet I kept missing it.,, You can now mix G61 and G64's to obtain selective CV mode if you wish.

To be more precise, I hadn't figured for Step/Dir Spindle whileThanks for the driver, still some problems You forgot to fix 2 start/run presses after toolchange and lathe macro. The two key presses is causing a problem, sometimes lines only partly execute and this may be affercting threading - still occasionally getting the stop, but what I am now getting is a stall on Z axis and feedrate is going mad occasionally. Here are results Normal Spin Count 2965 3007 2864 2884 Current Spin Count 4763 5440 11128 5305 Spin adder 2521 1828 701 2542 As you can see on third run it went berserk, said feed was .01 then 10, then 100!! I think until toolchange bug is fixed we may be wasting our time chasing bugs that may not exist. BTW - Setting a motor dwell also screws up threading. -- Steve Blackmore |

Re: Constant velocity/Exact stop

Bob:
Sounds like a bug to me. When you change the CV mode on the state tab, it changes a single varibale in the program. That varibale also controls the LED now on the main page. If the LED lights, then you should be in CV mode and further lines queued from that point should follow the setting. I will check to see whats wrong...( I think I already know...)...

Constant velocity/Exact stop
cnc_user
Hi Art;
When I set Exact stop on state tab and put a G64 in the program my machine still runs in Exact stop mode. Led lights to indicate CV mode but machine is still running in Exact stop mode. If I change it on the state tab it then works in CV mode. What I was looking to do was change back and forth between modes while program is running. Is this possible? Thank you Bob Harvey |
