If you are looking for a cost effective Z-table for your machine, then look no further! I found on Amazon (US) though no doubt there are other vendors - called a Lab Jack - scissor lift. Most of them are (only) 100mm x 100m, but managed to find a 200mm square one. https://www.amazon.com/gp/product/B073Z7BD5B/ref=od_aui_detailpages00?ie=UTF8&psc=1
Am going to have to modify it, and my my K40 slightly so that i can adjust the the height outside of the laser area. possibly just one of those flexible hexagonal screwdriver extenders. At $30+ it will pay for itself in seconds. They do have the motorised versions, but at a hike in cost
They work but kinda flimsy. I use a round bubble level placed on the material. The top tilts a few degrees so you have to make sure it is level each time you adjust it.
The other issue is that the screw to adjust the height is in the middle so it goes up and down as well. Makes it hard toi have it go through the front of the case, you need to make an elongated slot. If you can find one that has the screw at the bottom, it stays in the same spot vertically.
@HalfNormal yup - you’re right - a lot of info there. I didnt know they ware called Lab Jacks - when i looked through this community i was looking Z-table, so missed all these helpful posts.
