Re: Joystick (Wingman?)
Thomas Powell
Arcade joysticks will work good for on/off pushbutton type jogging too. Many and cheap on ebay.

Lots of Big caps
mike
I am getting ready to remount my drives. Can i mount a 10,000 micro-f
capacitor x 80 vdc (which i have) next to each drive (6" away) and skip the 470 micro-f capacitor?(which i don't have) my powersupply is 52 vdc @8 amps. which essentialy keeps a large battery bank charged. the current is leveled by a 67,000 micro-f group. the reason i am looking at this is room issues and (the real fact) that i would rather use things from my swollen parts box than purchase new. and i would realy realy like to see mach2 able to use another parallel port. (even if only the five input pins) Mike |

You have to have the force feed back hooked up to current sensors, that way

Hi Robin,of monitoring the motor load and feeding it back to the computer wecould make use of force feeback :-)WOW! great idea! I have DC tachs on my servos that are just hooked up to panel meters calibrated in IPM. While they are impressive to visitors, they don't do much for me any more, but with force feedback, my handheld controller could vibrate the faster my machine went! One down side is that if I sat the controller down to use the computer keyboard it would vibrate off the table. Gotta love this hobby!! |

Re: SoftLimits
Really ? didn't know that. Is it in the manual ?
Other point : it seems some beginners have never read the mach2 manual. There is 2 reasons according to me : - it's not easy to find on your site (perhaps a web shortcut inside mach2 could be fine). - it's big The lack of simple documentation for mach2 gives a lot of similar questions on the forum, for example it seems a lot of users have problems to understand limits and referencing, perhaps because it's too complicated in the manual.

If there was enough interest, Jim Cullins could design a breakout board that would use two parallel ports. For now, you can use two board. Bob Campbell Bob@... www.campbelldesigns.com Breakout board THC board sets CNC router plans Stepper Motors ----- Original Message -----

Re: Raster to Vector Converion - Try Rasterfratz
Rather than me re-inventing the wheel, has anyone evaluated theI tried Streamline and own a copy of Corel Trace. Both work but smoothing was a real problem. I had trouble smoothing what needed smoothing but leaving the detail alone. I also use Vector, so I downloaded a copy of Rasterfratz and it worked beautifully. It works seamlessly with Vector but also exports a DXF. The trial version is free. You should give it a try. I had a small project that I was able to do using the trial version. If more of those types of projects come along, I will definitely register. I think the price is $125. Well worth if for the amount of time it saved me. You can download it from www.imsrv.com Ross |

I tested at cv and full stop. Really doesn't matter, I still loose steps. I then ran it at 50% speed in cv mode and still lost steps. I am not missing alot, just enough to make me question my repeatability. Thanks, Mike Hammel www.fancyfoam.com 1704 Bullard Arkansas City, KS 67005 ----- Original Message -----

OXC usage
At this time I can call most of the procedures without Vb problems.
Can somebody tell me what the correct sequence of procedure calls is. (I.E. what needs to be done to initilize properly and what needs to be done to release control) Also can I attach to the current session of Mach2? Thanks Peter |

What should I expect?
INDECO
Hello all,
Today is the day I will be energizing the 2 servo's and 1 stepper for the first time, and I am not sure what to expect. I have never seen a system run, let alone build one and run it. Needless to say...I am a little nervous about throwing the juice to them. Besides smoke and disappointment, if I have made a mistake...:>( What should I expect the servo's and stepper to do when energized? Is there anything that may surprise me that I can avoid? Will the servo's take off as soon as they are energized? I have not yet set up any limit switches, and the servo's are monsters, with about 500oz in. If they take off like crazy they can do some damage..">( Thanks, Robin |

OCX working
It seems that the OCX is working.
I use the latest Mach235, Vb6 and Windows XP home edition. The first calls work OK, after a while I get "out of memory", this is probably related to me not using the OCX properly. Can anybody share VB experience with me? Any documentation on the OCX ? Best regards peter |
