Re: EMi and Loosing Steps Update

software would read the faults What I was not sure is. The axis stop moving was it a fault, or the buffer when the axis stoped the buffer was at 100% then it would go back to zero and the axis would start moving. When this happens the DRO freazes. I didnt understand how the fault wires wired to the senser hookup of the breakout board worked. The board is a pmdx-120.It's suppose to show a fault in the software I just don't now how Thanks Randy -----Original Message-----

Re: Mach software, HobbyCNC board and stepper motors, can I add XYZ encoders?
Yes, you can connect encoders on a second parallel port and use the
bidirectional board. . I also have a board that you can use to optoisolate the Hobbycnc board. It has a DB25 connector for output that connects directly to the Hobbycnc board. Other features are: - It gives you access to all the input and output pins in a concurrent way. - Has LEDs that indicate the status of all pins at all times.

Version 1.90.042 and PlugIns SDK
art
Hi All:
A severe error has been found on the latest versions of 1.90, the threading model was wrong for multithreaded applications. Since the PlugIns are threaded, this was causing some very weird troubles. The new version 1.90.042 repairs this. If your writing plugins , you also need the new SDK modules that have all been updated to the correct threading model. Sorry for the changes, but as the plugins develop, this is apt to happen. Im still searching for one strangeness, after installing 1.90.042, the first run of the program, may or may not, drop out after the splash screen. From then on , it will run fine. This version is more stable that several versions goign back a long way due to this new found trouble. (Or at least it is here. ). So if your one of the brave users of the 1.90 series, please update to the latest version, and if your a SDK user (very few of us, but growing..) please update your sdk files from the web site. Ill let you know when I find the initial run error, I suspect its a windows registration issue somewhere, Windows is pretty magical in this area, so it may be tough to track down. The ModIO plugin, in the SDK, is being reworked by John Prentice to add certain ModBus featyures previously unavailable, expect it to take a couple weeks for his investigations to complete I would think. Things are changing quickly in the SDK , so if your a programmer, expect to have to update fairly frequenctly for SDK work, but Im trying to keep that invisable from the user of Mach3 itself. The SDK is getting more powerfull each iteration, and pretty fun to play in, the G100 framework starts today, so Ill hopefully have test versions in a week or so which put G100 I/O and such in Mach3. Then jogging, then full G-Code movement. (Thats the plan..). Thanks, Art www.artofcnc.ca Videos And Support Forums Users Map: |

Using USB Devices
Hi
I've just one of the Logitech wireless gamepads - looks a bit like a playstation controller. It is brilliant as a jog controller! The thing i'm interested in is that I have found an interesting 'issue'. I have two hard drives in my PC, one for general and one dedicated and optimised for Mach. I set the gamepad up in my general windows and then tested with Mach. Worked perfectly whether the gamepad software was running in the tray, or fully open for editing. Switched over to my Mach windows and found that the mach driver will only run if the gamepad software is started first and only running in the tray. If I start the gamepad software after mach, or open it editing then the driver freq drops to 100 and time in int varies widely (2-32) and the driver test refuses to run. If I start the software in the tray before mach, the driver test shows great and the freq and time in int are rock steady. I was curious as to why this might be affecting the optomised windows and not my general one - it's the same hardware, windows version etc? Cheers Dave |

You can drop on an LED, set its OEM number to a User number like 1001 , then in a MAcroPump , use a line like If IsActive( OUTPUT1 ) then setUserLed( 1001 ) endif The LED woudl then reflect the output1 signal, no matter what pin its on.

Re: Difference 25Khz -> 45KHz
you just have to know how much steps your driver need to make one spindle
rotation (most servo controlers have electronic gearing so you can adapt to your needs). then you can compute the max spindle speed you can get with a 45 Khz output. At 45 Khz, mach3 will output 45 Khz if the motor tuning speed setting is at the max value. Olivier. |

Sorry i did not tell you that it's for the spindel i'm planning to use the brushless motor, and not as a servo.The basic difference SHOULD be that at 45kHz you can run the stepper motor nearly twice as fast as at 25kHz - if everything can cope with that. If you are using a simple full step drive to the stepper motor, 200 pulses rotates the motor once, which will take 8mS at 25kHz but only 4.4mS at 45kHz. Change to half or quarter step, and the times increase, so half stepping at 45kHz will then take 8.8mS for a rotation, slower than full step at 25kHz. Changing to 1/8th step really needs more than 45kHz to get full speed out of a good stepper motor, but will be very smooth in it's movement. -- Lester Caine - G8HFL ----------------------------- L.S.Caine Electronic Services - Model Engineers Digital Workshop - Treasurer - Firebird Foundation Inc. - |
