General Mach Discussion / Re: Problem with Backlash...

Rich and Woodycam,

Thanks for good explication of my problem, it's exactly my problem.
It's possible find a software patch for ""fully honor the axis acceleration parameters when compensating for backlash""
At my sense why include this parameter (backlash) if not operate with other ?

Thanks

On other lathe I use Deskcnc before and now use Mach3 and the drawing are import from deskcnc and all work fine on other lathe but this lathe have no backlash and a very light carriage

Thanks for help Rich

Thanks Rich,
But yes I already try to running at slower speed and the problem is always here because at my knowledge when the X make a backlash adjust the Y seem not use slope for stop and start .Also any speed I enter do not change the result...motor skip when restart...;-(((

Hello Rich,
The lathe is not here but the velocity is approx X=22 IPM  and Y is is 30 IPM
Because it's an older metal lathe the carriage is very heavy (approx 200lbs) and it's hard to move also the slope for start and stop is approx 1.2sec
thanks
Claude

Hello Rich,
The problem is not with axis with backlash but the other...I try to explain with my bad english...;-)))
When X axis get back the backlash, stop for a fraction of time the Y axis and when restart the motor go skip even if the backlash speed is 5%...

Hello Rich,
Thanks for your response,effectively lathe use X and Z but I use Machmill for this machine because with Machturn the drawing is not translate correct.

Hello.
I'm new on this forom and on CNC world.Also I,m a french Canadian and sorry for my bad English !!!

I modify a metal lathe to turn wooden piece with step motor...good.All run great but I have a .008 inch of backlash on Y axis and I have a problem when I use the backlash fonction on Mach3. I expland...The backlash function operate well separately but when run a program the function didn't run because stop and start X axis with not slope programed...

If anything have an idea for resolve my problem I appreciate.

Thanks
Claude Turcotte
