Blessed,
These are the instructions I used to do my conversion way back when: https://forums.maslowcnc.com/t/bosch-pof-1200-z-axis-conversion-guide/5154
There is a link to the STL on Thingiverse.
And here is the sled design I created: https://www.inventables.com/projects/maslow-bosch-pof-1200-sled
As to a video, I didn’t record building it, since I was following a well-written guide already myself.
If you can’t find anyone in NZ to print it for you, give me a shout, I’ll see how much the postage will cost.
Regards,
Peter
