SmoothStepper USB / Re: Override Limits issue - does it relates to SS?

It works but it's funky.  You have tho click the reset button 2 times.  Then it should allow you to move off your limit switch.

Thanks, I'l bear it in mind.

Today I have tried this with PP version and manual limits override works well.

woolexmail, of course you are right. But you are spoken about ballscrews for big boys.  Because of lack of space in Chinese X2 minimill, Mike (Cncfusion) gets a usual cheap ballscrew with a single nut and "preloads" it by changing balls for bigger ones. Speaking correctly, there are not a true preloaded nuts, but a nuts with minimised backlash.

PS: Today I have downgraded to printer port, so, waiting for backlash compensation implementation in SS plugin.

The screws themselves seems no be new

"to be"..... or "not to be"......THAT is the question. 
Couldn't decipher what your actually trying to type.

Sorry, the screws themselves seems to be new, but a "preloaded" nuts gives this backlash.

Just discovered that manual "Override limits" does not work. Red led flashes, I push a Reset button, but I can't jog out of the switch. The same time AutoOverride Limits works well, homing works well, limit switches themselves works well. Everything, concerning a limit switches, works well, except of a manual Override limits. Does it relates somewhere to SS?

What make model etc. ballscrews did you buy.

I have bought a cncfusion X2 ballscrew upgrade kit with Thompson screws, preloaded ballnuts and a zero backlash helical couplings. The screws themselves seems no be new.

Without a load at all, backlash in ballnut is near 0.07mm, so it is not a flextire. Other is a flexture of the ballnut mounts, so after a precision adjustment a have a final backlash on X-Y around of 0.07mm

Backlash is between 0.07 to 0.15 mm depending of the load.

What a pity...
So, a have to rollback to PP, but still waiting for a backlash comensation.

SmoothStepper USB / Backlash issues.

Hi, all.

Today I have assembled  X and Y axes of my X2 mill with cncfusion ballscrew upgrade kit and after a first run I have measured a backlash in it.
Then a I tried to switch on a backlash compensation in Mach3, but nothing happens. Compensation, tested with G1 commands, does not work.
Of course I have restarted Mach3 after switching compensation on.
I'm using Mach3 3.042.018 and SS board Beta2_v015me.
Does it exactly a SS plugin issue or I'm doing something wrong in setting up Mach3?

Best regards,
Anton.
