New PM-728V-T Mill

Yes it does run Fusion, Centroid Mill Pro, Mach4 (for the Avid CNCRouterParts plasma table), and Sheetcam, and usually have several of them open. For example when I cut with the plasma, I use Fusion > Sheetcam > Mach4. It does have the Vesa hole pattern on the back as does hte monitor, but I mount them offset. The monitor, btw is the Planar Helium PCT2235 Touch Screen 22" LED LCD Full HD Resolution Monitor with Helium Stand

Nice clean and compact setup on the monitor. What is the Raspberry Pi for?
 
I wanted to use it for an Arduino project (with motor drivers for some NEMA17s) but have abandoned that project and that pi is repurposed for photo/video backup storage now. I will remove it from the workstation above and put a DIN rail in its place, onto which will go a PS and an ethernet switch as part of my PM 728 CNC conversion.

One of the disadvantages of the NUC is that it only has one ethernet port, and I need to drive two separate CNCs, one w/ Acorn the second with ESS/Mach4. I will use the switch to not have to swap cables out.
 
anyone know of a way to adapt a 3/8 in shaft servo motor to the 8mm coupler? Same with a .5 in servo to the 14mm coupler in the Precision Matthews CNC kit.

what are the shaft sizes on the screws? Might need to search a bit but lots of options.

I like this style

Thanks lmrk. The PM-728vt CNC kit shipped by Precision Matthews has 10mm ball screw shafts on x, y and z. The motor-ends of the couplers that came with the kit are 8mm for x and y and 14mm for z. I'm using ClearPath servos, and they are .375 in shafts for x and y and .5 in for z.

from the above link you can get the 10x12.7

BTW, you might need to go with the same style as PM sent so they will fit with the mounts. I was able the make the mounts fit with the couplers

With those couplers each half can be selected for different shaft size, as I understand it. So you can just replace the motor halves.
