General Mach Discussion / Re: hello every one, im new, i got a question

« on: July 21, 2007, 09:26:22 AM »

hi benergy
And welcome.

Somewhere, and I'm sorry i can't find it at the minute, Art has posted the definitive explanation on this site.

Basically your machine is behaving correctly. To borrow Art's similie you could drive down a street to a right angle corner and take it safely if you're travelling slowly. If you speed up you ain't gonna make it. So you slow down towards the corner, or cut the corner, and this is what your maachine is doing - looking ahead for those corners it won't get round.
Find art's explanation. The complexity of the calculation is amazing.

Hurcomatt.

If you didn't find the answer yet, there's contact details on www.geckodrive.com, where you may find the answer, and there's a yahoo group -geckodrive- which might help you.

Good luck with the project.

What do you mean 'pantographs' Tiger?. Is it like Vectrics picture cutting software? Not sure what you are trying to make.

You may be on crack, or wrong IJ mode. In mach 2 this may be sorted by toggling the IJ mode in config.
Apologies if it don't apply to mach3. Must upgrade.

All running again, just like before. Thanks for the diagnostic help,thanks for the loan of the Gecko, it's really helped me complete this urgent job, and I'll get it or one back to you asap.

HI Don.
I cut acrylic a lot. It was suggested on this forum that air cooling is good, and now I have it set up I agree, but it ain't a $300 dollar vortex it's a pipe from a compressor. A very thin jet straight at the bit. It is so effective that when I turn the air down there is a point where all the cuts are clean excecpt those odd ones in the direction that is  sheltered by the bit, and in that region there is a touch a hint of rewelding.

Just thought it might help

Not but . You've found the problem for me thanks.

No UK supplier then?

Did you say about £80 Shipped from the States? But compared to the £175 i shelled out for the MAE 300 3438 430 a8, the other day....anyone interested?  No it was sale or return, thanks Cetronic, so it's cost me a few quid to confirm it wasn't the motor.

You don't have a spare Gekko anyone? I was halfway through this urgent job, as always....

Thanks again Hood.

Thnks Hood, will do. All terminals or 1 through 6 or what? (they are a way apart)

Also noticed the X power on light dims well before the others after power off....

Hi all

Well, the new motor does the same, do I guess it's not that.

What's the next step?
Nothing changed, it went rough mid job. What could alter and cause this problem?
