CNC conversion of my Toolmania WBM16LV (TM BF 16) mill with NEMA23 steppers, 3dprinted adapters, teethed wheels and teethed belts

Before My Toolmania WBM16LV milling machine was delivered I already had plans to convert it to a CNC milling machine.

I do have some experience with 3d printing, and I have 2 CNC routers up and running, like the Indymill.  So, the conversion of this mill will not be difficult in the Technical sense.  But- making the perfect designs for the adapter plates of the Y- and X- axes proved to be a lot more work than I expected.

The column cutter is already equipped with glass scales with digital readout.  Furthermore, there is a gas spring mounted on the Z-column so that not all the weight is in the way when moving back and forth.  Also an automatic lubrication system for the slides of X, Y and Z-axis will be mounted.)


The electronics will become OpenCNC + wifi + wireless controlbox. I received the kit and will put it together the coming weeks.  For now I am going to set the mill up with my all-in one USB-CNC-MDK2 board.  I use this for all of my routers and mills to get it set up in first instance since it is very simple and sturdy. And- you can run it instantaniously without any PC or programming, just with the handwheel or from SD card.  And from the laptop, of course.

GOTO the X axis CNC adapter

GOTO the Y axis CNC adapter

GOTO the Z axis CNC adapter



After this all worked well, I also made designs for  NEMA direct drive adapters on my Toolmania MiniMill:

Direct drive adapter for the X-axis
Direct drive adapter for Y-axis

Above: Direct drive adapter for the Z-axis

left top the Z-axis adapter, right the X axis adapter and at the bottom the Y-axis adapter

What makes it tricky is the choice to make: Will I replace the spindles with ball bearing spindles or not?  Not for the time being, first let’s make everything on CNC and then I’ll see how it performs.
