Desktop size steel welded router 3 axis

[JAZZCNC]

Still trying to decide if this a moving gantry or Fixed gantry machine.? In both cases I'd change a couple of things on the main frame but will wait until you clear up which it is.!

On the Z axis I'd switch the rails around and have them on the front plate with bearing on rear plate. This will give you a variable length lever depending on extension compared to the fixed length one now at any extension.

I also wouldn't use a Kress router has it will be letting a nice stiff little machine down. Either 1.5 or 2.2Kw water cooled spindle is the right tool for this machine and won't cost much more than a Kress. It will last 5 times longer with much more power and lots quiter and I mean lots.!!
