Bardac makes a pretty good DC motor controller several centroid retrofitters have used them in the case where a machine has a DC motor and is too cost prohibitive to refit with an AC motor.

lots of lube pumps on ebay.
elrod sells a good one as well.

and thanks for posting how to flip and input with control alt i.. that is explained in the allin1dc install manual on page 23 at the top.
thanks.. please post photos of your machine and installation. best regards,Keith

the allin1dc can accept 20 to 180 VDC "bus voltage" that is used to run the servo motors. its up to you to step down the AC input voltage to the CAPboard so that when that AC is rectified the proper DC voltage is created to match the specification of the servo motors you are using. for exa...

also be sure to adjust the Fast, Slow and Rapid rates for the rotary axis.. as they will now be in degrees per minute.. so typical values are
Slow jog = 2000 degrees per minute
Fast Jog 4000 Rapid 9000

i attached a rotary table install manual as a general guide

when you define an axis in the CNC11 setup parameters as a rotary axis (not linear) the turns ratio units in the setup table want REV/Degree revolution of the servo motor per degree of movement so in other words.. how many revs of the servo motor will produce 1 degree of movement on the rotary table.

thanks for posting your experience with ajax and centroid. and keep posting photos or your projects, always interesting to see. here is a link to a photo gallery of completed projects. http://www.centroidcnc.com/cnc_retrofit_images.html and a link to Marc's webpage is http://cncsnw.com/ with good in...

yes, move the switch, check action with estop depressed to make sure the swtich triggers before you run out of travel. its good to leave .050" or so. then reset travel limits.
take a look at this tb

yes you can set the machine up to do just that. there are several ways to "home" the machine each time you power up so it will remember your part x,y,z zero position (and all the other WCS positions you have setup ) as you could imagine this is a real time saver. automatic homing is availa...

there are several ways to handle the limited z travel of a typical knee mill. one basic way is to create a part program to do all the machining with the knee at one Z position. and then drop the knee, reset just the Z part zero (wcs) and then perform all the drilling operations at that new z height ...
