General Mach Discussion / Re: Can't zero DRO or home more than once??
« on: November 17, 2015, 10:35:47 AM »
IS this MILL ? Turn ??

I have no idea what this means " Just noticed this too, If I zero WCS, then move, then reset, then go to zero one axis, they all zero?"  TRY NOT to use abrieviations when describing a problem. To me WCS is World Coordinate System. ??

WHAT did you reset ???

Did you set up soft limits ? If you did AND you were outside the limits then it will NOT move to refhome. ??

I have never seen this problem with the LPT version.

Hey Mikey, Have you gotten anywhere with this so far ??

Here is teh link to Arts article on calibrating a step/dir spindle.

http://www.machsupport.com/forum/index.php/topic,18580.0.html

IF indeed mach3 is still controlling  teh spindle which I don't think it does then Art wrote an article describing exactly how to get teh Output linear. He wrote it many years agao AND it worked great. I could get teh RPM +/- 2-3 rpm across teh entire range of RPM with a Step/dir spindle controller.

I see if I can find it and post it again. It is probably on this site allready. Just have to look.

(;-) TP

Mikey, You need to call Brian @ artsoft and see if he can help you setup Mach4 for TURN on that machine. You already have all teh hardware in place just need the Mach4 setup.

THAT would be a great project for everyone to watch unfold.

(;-) TP

656
It would have to be a ESS issue as IT is what actually controls the spindle . You need to speak with Greg over at Warp 9 about this issue.

EVEN IF you could get Mach4Turn to work the ESS still controls the spindle (;-)



(;-) TP

657
The LPT version and the ESS version are 2 different CATS. 

(;-) TP

658
Mike was the OTHER lathe using the LPT or the ESS.  With teh ESS the spindle stup is ALL done from teh ESS side NOT from Mach3.  IF Greg never setup closed loop control then it will NEVER happen.

are you confusing teh OpenLoop Control with CSS ???

(;-) TP

659
HIYA Mikey , First closed loop NEVER work worth a hoot even with teh LPT and I dought it even works at all with a ESS. What you see is a linear config error. The voltage output is NOT linear with the RPM called. THAT is a function of teh ESS to control that probably a ESS setup problem with teh spindle control.

Normally MACh3 does NOT attempt to correct ANY spindle speed. You just have what the spindle is doing and that is it. IF it boggs down it just boggs down UNLESS your spindle speed controller itself can do Closed loop control and MOST don't unless it is a SERVO spindle.

IF you were useing an LPT I could show you how to correct the linearity problem BUT I don't know squat about the ESS's spindle output control.

BUT there is probably a manual out there somewhere that may have the answer ????

I would just use thestock screenset and find a macro to do the probing for you.
