Mach Screens / Re: Screen4 has PMS, help me.

Thanks Dave and Jason for solving my problem.

I am running Vista. Guess I will just have to put up with it. It still kind of works just not very well.

Cheers,

Alex

Thanks Dave,
I have installed it over 4 times now.
The original screen editor seems to work fine but I cant save as a  “set file”.

When I download screen4 from the mach website, would it make any difference if I turn off the firewall and spy ware on my computer? Can that mess with the file being downloaded?

Mach Screens / Screen4 has PMS, help me.

« on: November 21, 2008, 07:58:58 AM »

I am having problems with screen4. It locks up and/or takes minutes to respond when I click on the main menu’s [file, edit, view, defaults, help]. Also some other weird things have happened [most likely user error] like saving a file and reopening it to find everything has shifted over by 800 pixels!

Is anyone else finding these problems? How can I fix it?

SmoothStepper USB / Re: Backlash issues.

Anton, lets start at the beginning here. A ball screw and nut used in a cnc application would 98% of the time be pre loaded. This means [basically] that there is negative clearance in the assembly. This preloads the balls between the nut and the screw shaft to a given value. When a radial or axial force exceeds the preload value, plastic deformation occurs. The result is backlash and a very unhappy ball screw. Otherwise your ball screws should have 0 backlash [to a point!].

If your ball screws have backlash then you have some issues to take up with the supplier [possibly wrong nuts]. Unless as pointed out by Rich, it was a system designed for preloading between two nuts in the first place.

Are you running the drives directly from the parallel port? Apparently that can be an issue with geckos. There is not always enough grunt form the parallel port for them to work properly. That may be a load of B.S. I just remember reading that on someone’s website who was selling breakout boards.

General Mach Discussion / Does the G100 firmware support backlash comp??

« on: November 01, 2008, 02:55:26 PM »

Apologies in advance, I know mach is finished with the g100. Still I have an important question in regards to backlash comp. In the g100 posts, it is mentioned that backlash comp was/is not supported. Is this correct with the current firmware?

Thank you Hood and Caoticone for you input.

So whats the latest and greatest motion controller that is better supported by Mach3 and possibly Quantum futher down the track?

It would seem the G100 been abandoned in many ways. Is it to complex? To many bugs to iron out?
I have one and it works fine in regards to basic inputs and outputs and driving motors [at the moment]. Are there many people successfully using them on a day to day basis? Will the new generation “quantum” be of any help to G100 users?

Reading some other threads, it seems there are some problems with the G100 and setting up a spindle pulse signal for threading. Is this still the case?
