Nah but I do have a pallet of Latex I can sell you.???. . . .Gloves. . . .( Also Nitrile and Vinyl if that's your fetish. . Lol)

OMG lol What did I just walk back into?

I wanted to update you on my progress with getting this jumping/ noise issue out of the way. Well... I figured that you guys Jazz I think mentioned it first that I was expecting too much and the speeds were too high with the rapid and cutting settings.

Well, Lo and behold after trying lots of different tuning combinations. I discovered setting the speeds too low also made for some horrible sounds. But I came across a another post with some supplier recommended settings. That were indeed a lot slower than what I had been gave.



These settings were actually found to be the best for my 6040 machine. And they are

steps velocity accel' step dir
X 320 2000 200 10 5
Y 320 2000 200 10 5
Z 320 800 150 10 5


My old settings that made the occasional noise and stalled the motors were

steps velocity accel' step dir
X 320 3000 200 3 1
Y 320 3000 200 3 1
Z 320 800 200 3 1


It sounds loads better now and doesn't fly about making my table shake slightly with the speed of movement of the gantry.

I have re-cut a few test pieces and haven't had the horrible sound or any missed steps.... yet ;-) Never say never eh!


I just want to say a really big thanks to all you guys for all of your invaluable advice I really do appreciate it and would have been stuck without all your help. cheers guys
