Finally got my TBD CNC Supergrade Z axis running. Complete with Hitachi M12VC router upgrade.
Upgrade itself is incredibly easy. Calibration was as simple as typing in a few numbers and using a digital caliper gauge to ensure the height is as perfect as can be.
First few cuts and it’s noticeable immediately what a difference it makes having a linear direct drive axis versus belt driven.
The OEM X-carve does a very admirable job considering how simple its design is. The sheer accuracy of this Z axis makes it worth every penny you spend.
There is absolutely zero play, slop or chugging as I call it.
I’m now hell bent on selling some more in order to afford the direct drive upgrade they have for the X and Y axis.
My only beef here is I wish it were possible to get a screw drive Y axis that would afford 1500-2000mm in length as it would give us the ultimate hobbyist CNC.
For what it’s worth this is the best CNC investment out there. OEM is less than Shapeoko out of the box and with the savings you can easily upgrade to a very Formidable machine.
