Mach 3 spindle
zcases
I am converting to M3, and trying to control a spindle with
step/direction and a VFD. I have the pins set to the same pins as M2 and active low, duplicating my functional M2 setup, but I get no spindle rotation. Is there another option or setting in M3 I may be missing? What are your ideas? Thanks Scott |

(a) is messy because of all the steps setting it up and the fact that the macro needs to find which input caused it to run (if you have several. (b) is messy because you usually have to notice changes of the input as you will not want to run the code everytime the Macropump runs - only when the button goes down (or sometimes up) Have a look at section 4.2 of for the OEM trigger technique and for the Macropump. Bot relate to inputs via ModIO but there is nothing special other than defining the input port as 0 rather than 1 or 2. Let me know if you need more detailed pointers John Prentice |

Hi Tom:

Sorry, I meant to respond to this earlier. You need the SetMacroTrigger() script call. Calling a user script is a bit of a kludge. You call SetTriggerMacro( MacroNumber) , the macronumber is the file number like m666.m1s woudl be SetTriggerMacro( 666 ); Then you use OEMTrigger on function #301 to actiavate that file. The SetMacroTrigger must be called before the OEMTrigger on function 301 will work. (Im thinking of a new way to do that which is easier, but its a bit of a bitch to get user buttons, they dont exist till the program is fully iniitialised..)

Currently no network stuff enabled!Well it is some process running that stops things. You will then convince yourself that Mach3 cannot work at all :=) The Bresenham algorithm gives average pulse rates that can be set at much finer than the granularity of the basic engine. With an analog 'sco[e this looks like multiple superimposed trains (which in a sense is what it is). A digital (or storage) 'scope will show the pattern to get the required average rate. As there is really no way to trigger on the "tick" it is a software hunt that you need or, indeed as suggested, a conventinal desktop motherboard with graphics card in PCI or AGP slot until you get it going to your satisfaction. inputs, but that is the point when G100 comes into the equation anyway.I was arguing the case that my tests with Modbus and a big macropump suggest that 1GHz is safely "in margins" when not burdened - rather than that is what you would want to do. The "required speed" thing is not an absolute and as I say CPU speed does not affect pulsetrain purity. Provided there is time for the drive code to run it will do its stuff accurately. If there is not time then the machine sticks its feet in the air and does nothing. John Prentice |

From: "Lester Caine" <lester@...> To: <mach1mach2cnc@...> Sent: Saturday, June 03, 2006 3:16 AM Subject: [mach1mach2cnc] Slow computer Right guys ( and galls? ) Spent some time yesterday playing with a TaigCNC machine and comparing Mach3 with the DOS package that normally drives it. The original control program is running on an old machine that would probably not even load W2k so I had taken along an ITX box with W2k already installed. Only problem is that it is an 800MHz C3 processor, but since this is intended to be an embedded computer to go with the machine nothing else was installed on it. Operation from the DOS program is smooth and clean, but running the same tests in Mach3 give a number of problems. Even slowing things down, running just 25kHz and slower feed rates we have a decided 'pattern' to the noise from the stepper, like something is sticking every couple of seconds, while the DOS has none even at a faster rate. Is this likely to be due to the fact that the processor is not fast enough? Neither of my laptops have parallel ports, so I could not hook them up, and the desk machines are rack mounted, so until I can get a machine over here it's difficult to try a faster processor. What *IS* the slowest processor speed that will work cleanly - or is the less than smooth pulse generation a 'facet' of using windows? Given the quality of work that the machine CAN produce, any pattern to the axis movement is likely to affect the surface finish. Ideally I would like to include a 1.2 or 1.5Ghz ITX based processor with each machine but I am wondering if that will work, or if I am stuck with just running DOS and leaving Mach until the G100 or something similar is a cost effective alternative :( I will leave the other problems until I can run things with a faster processor ;) -- Lester Caine - G8HFL ----------------------------- L.S.Caine Electronic Services - Model Engineers Digital Workshop - Treasurer - Firebird Foundation Inc. - www.machsupport.com - Web site Access Yahoo!
