I received my kit a few months ago. When I opened it up, I found a lot of pieces that hadn’t been mentioned and I had no idea their purpose. For instance, what’s that second power supply for? Oh, that’s a relay for the router, bonus!
One day while randomly browsing the forum, I ran across this thread in the Swap Meet category: Metal Maslow kit $600 ships Nov. Respond below if interested. A lot of the information you’re looking for is in this thread. It’s a bit frustrating that the best collection of information about the Metal Maslow is in the Swap Meet category rather than Hardware or Technical Details but such is the nature of a community like this - chaos feeds creativity.
There were a few QC issues - like your screw and hole mismatch above. Countersinks and counterbores were at inconsistent depths, the holes in the Z-axis sled needed to be tapped and there was some interference between the Z-axis sled and the linkage support. There are different size set screws on the same sprocket. But the system as a whole has been pretty well debugged so it saved a lot of time versus collecting all the parts myself.
I’ve been a little confused about various statements regarding the pitch of the lead screw. My kit contained a screw with a single lead with a pitch of 2 mm. Entering 2 mm didn’t work, the z-axis moved a lot farther than it should have. After some research, I found that the correct value for the z encoder steps per revolution is about 600. Using 2 mm and 600 it was really close, but also really, really slow. I discovered that multiplying both numbers by 10 retained the accuracy and sped things up a lot. The numbers I settled on are 20 mm and 6031 steps per revolution.
