The Homann Designs’ DigiSpeed-XL and CandCNC Mini-I/O boards have finally been hooked up together and tested under Mach3 using PWM. Pretty cool so far!
We’ve been working on the home-brewed CNC vertical mill lately. The latest development was the installation of the cast iron T-slot table.
While not the ideal table width, the depth of just over 6” makes it heftier than the X2 mini-mill base (though not as wide). Eventhough the base isn’t as wide as the mini-mill’s, with the travel this mill has, makes that dimension only important in that we can’t clamp the workpiece to the table should it reach a size of 6” x 12”.
We’re pretty happy with many Phase 2 products such as their line of QCTPs for the mini-lathe, but their X/Y table is just about the worst quality piece of tooling we’ve ever purchased. It took only a quick glance at the table to realize that sacrificing the table wouldn’t cause any heartburn.
As an FYI, the part number is 260-512PHSII “Compound Slide Mill and Drill Table” (ENCO part number 201-2826 often on sale for $70). From the moment we took delivery of this table, one of gib set screws broke as we tried to tighten it. The backlash on the leadscrews is the worst we’ve ever experienced. The bottom line is that the only salvagable part is the cast iron table.
We’re a bit late in posting this update…
A week back we received both the KBMM-125 (similar to KBIC-125) DC Speed Controller with their HP Resistor and Heatsink to bump capacity to 1.5HP instead of .75HP and the Homann Designs Digispeed-XL motor interface controller for Mach.
We’ve been busy working on a design of a 3-axis adjustable post mount for the Z-axis of the CNC mill, so these boards have been sitting on the table:

We received the CandCNC Mini-IO board recently and immediately hooked it up to the Gecko Drive G202 drives and the KelingInc KL34H95-43-8B step motors.
