MPCNC to LR4

Just thought I would start a thread for upgrade of my MPCNC to the LR4. I plan to use the same table but add some “Wings” to the front and back to get a little more cutting Area. Attached is what I am thinking for the table. Would love your comments as I start adding to this thread. My goal is to be able to handle 2x4 foot sections which should accommodate most of my projects. If all goes well and I find myself doing more, I may make it larger. ITEMS PURCHASED IN ADDITION: Aluminum X…

Some have started, not sure if anyone is finished.

You will need the linear rails, XZ plates, lead screws and an extra endstop for sure. The rest will all be hardware like M3s and such. Not sure if the LR3 to LR4 upgrade kit will be enough M3 screws or not, but would sure be a good start and get the most from Ryan that you can.

Question, are the stepper from the Primo Nema 17 70Oz/in+ go enough for the LR4 Stepper Motors -Nema 17 84oz/in
Or will I need to purchase the 84oz/in

They will work. You can adjust the current to them if they are under powered. The default current is 0.8 but can be increased to 1 or 1.2 A at the risk of passing the PLA glass transition temperature at 60-65, which will allow it to more easily deform if the motor heats up too much with that current.
