General Mach Discussion / Re: Steppers stalling at a certain speed

« on: June 08, 2011, 03:25:39 AM »

If it's 'mid-band resonance' there are 'easy to make' mechanical devices that can be fitted to the steppers if there is room. There are also electronic solutions as built into the Gecko drives etc.
There is much information on this subject both here and on the Zone if you do a search.

Thanks Russ, you are of course quite right, but he did finally meet a fitting end.

I finally got around to making another "Che" coaster and more or less got the cut-out dimensions right this time. The problem is that, for the same power settings and feedrates, different types or wood veneers laser cut with different kerf widths. Still, I am quite pleased with the result - just need to make a couple more, with different images for the set

General Mach Discussion / Re: y axis stalled? during cutting - please help

Thys,

I started using a bit of scrap plywood as the spoil board but you have to make sure of the final pass depth so that the cutter doesn't go down into the glue layer.

Hi Thys,

This a wild guess but if, on the last pass, you are machining right through into a spoil board which is something like MDF then the tool tip (which is now in a pocket) can get clogged with the dust and may require extra torque to cut properly and thus stall the axis.

As I say, just a guess.

Perhaps I should start gathering all that odd info up and publish it somewhere???

Brilliant idea Terry.

I doubt the VB problems will ever be solved because once I get something to run nicely when I update to the next version of Mach everything changes and it's back to the drawing board.  My main problem is with the little used commands (I suspect that it's only me that ever used them) such as E1P0/E1P1 etc - they used to work so well.

Sorry rrc1962 I am rambling.
