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 XY Plates - V1 Engineering
150mm MGN Rails - V1 Engineering
M3x10mm screws - V1 Engineering - YOU NEED MORE THEN THEY SEND YOU
Made Second order of M3 Screws
5mm to 8mm flex coupler
GT2 10mm belts - enough for the project
Limit Switches - You need to order 1 more.
Once assembled:
Flash Software from MPCNC to LowRider LR
Check all of your endstops to make sure they are correct - Use the M119 Command
Parts are printed, went fast between the three printers. Voron 2.4 got the core done quickly. Check your YZ plates and make sure they have not warped from the print bed. I had to re-print one of them. There are a few characteristics that are sensitive to the warping.
When routing the wires through the housing, wait on making the final route for the “Y” motor and sensors. Get the “Z” motor in first and use the “Y” connector to push it from the bottom. Then push through your sensor wires. had a hard time getting the “Z” connector through.
This is an awesome look at your MPCNC! I love that it looks well used.
I converted my MPCNC to a LR3 a while back. I just put a flat piece of MDF over the area and built on that first.
I did eventually re-create most of my workspace in a LR3 table. For instance, you have the dust flaps, your control box and E-stop, and your tool shelf which may need to be reconfigured for a LR4 anyway. Once its up at running, you’ll be able to make a decision as to whether “wings” will be supportive enough.
I chuckle, because my MPCNC spoil board looked suspiciously similar to yours, at least with the regularly spaced anchor points. I completely abandoned that strategy with my LR3 and haven’t looked back.
Now its just another shop keepsake, obstacle to trip over.
Sorry, the build went oh hold due to travels, working on it again this weekend.
M3 Screws - I purchased some from V1, but there was not enough in the package for the project, I have a second order in.
Limit Switches - You need 2 more minimum… I ordered 3 more over the MPCNC.
Thanks for posting your experience here. I just ordered parts last night to switch my 4 year old MPCNC over to an LR4. I’ll be watching your progress and will hopefully only be a week or two behind.
Would someone mind posting a picture of the Ymin Endstop from directly above? I just want to understand the location of the tube / last clip to the end stop. Just curious how you located the holes for drilling? just a pencil inserted into the end stop?
Finished cleaning up and terminating wires
I really like how clean this is compared to the MPCNC. Once I build the strut plates, I will get everything tucked in to the controller. Hope to have some initial movements shortly.
Just curious how everyone routes the power for the MPCNC as well as the Router?
