Re: Acorn Geckodrive g320x

ok, now we are at a good baseline. the disk images show that this is classic Lost Motion. with the machine off put your hand on the screw turn the screw 1/8th - 1/4 of a turn CW then CCW, back and forth. you will feel the 'lost motion' you will be able to rotate the screw for a number of degrees tha...

Re: Deckel fP4A Dialog11

seriously though. I did one of these machines about 10 years ago and went thru all the effort of updating the encoders (building adapters and covers and cables) and using the centroid AC/DC drive to run the big old siemens servos. I would not do that again, too much time and money and still have old...

put 0.000 in for all backlash compensation

and make a test cut.

Re: Acorn Geckodrive g320x

you are mixing two different things together. overall turns ratio does not solve mechanical backlash. by changing the overall turns ratio you are making things worse at this point. leave the numbers at 8 do not adjust them. now figure out where the backlash is coming from. it is Large so it should b...

Re: Quick Tip: IF you have Home/Limit Switches, here is an example and description on setting them up

with the addition of "HomeLimit" inputs in the Acorn Wizard, this allows a single switch to act as both a limit and home switch just like oak/allin1dc also you can now have a dedicated limit switch inside of a home switch (a limit "protecting" a home switch) with Acorn as well. a...

Re: Spindle analog output low voltage

Is there any settings and or parameters that maybe causing this voltage problem? Ill have to double check the wiring again to see if Im missing something, as far as output to the VFD I just have forward and reverse and obviously the analog out and com. if cnc12 thinks there is a touch probe plugged...
