I’ve just completed my LR4 build. It all seems to be working. I have a Jackpot board. I can connect to it via the webui, move it around the axis and it all looks good. It also appears to home correctly.
I’m feeling really lost at this point as to what I need to do next. I know I need to square the board, then surface it etc but I’ve read the documentation a few times and I am just really confused.
Would someone mind breaking it down into simple steps for me so I can get this wonderful machine dialed in?
For the squaring, you are just moving to the four corners and making a dot or putting a hole in a piece of tape with a sharp endmill. After you have the four dots, you measure them diagonally and see if the number is the same. If not, you are changing how far off the machine moves off the endstop on one side.
For leveling, you are just making the z axis go down the same to reach the same point. For example, when your endmill hits the spoil board on one side, it should also be hitting on the other side.
Where are you stuck specifically? What have you tried?
The Z axis is also making a loud squeaking noise when going up/down, I feel like something isn’t aligned properly. When I moved the machine all the way to the bottom of the Z axis it got stuck and wouldn’t go back up
Realigning the lead screws and some lubricant has fixed the z axis, it looks good. Now I just need to work out how to send gcode to the machine to test.
Start by checking out the tools - Milling section of the documentation, which includes a section on Setting up EstlCAM page (scroll to the top, the link takes you down the page a bit).
Then strap a pen or sharpie to the core and trying to draw a crown (a link with full g-code is in the documents page above, as is a DWX file that you can resize to fit your table)
That should get you moving around and familiar with the main concepts. After that you can put in a mill into your router and try some test cuts. I recommend doing “air cuts” to start (set your z=0 a few inches above the spoil board), and then try cutting some styrofoam before you move onto harder stuff like wood or aluminum.
From a browser on computer where you made Gcode file, connect via the webUI. In the file section, there is a little option to choose between whether you are looking at files on the flash storage, or on the SD card, you want to switch it to SD card. Then notice there’s a little drop-down arrow thing up to the right of that file section, and when you tap on that, it gives you two choices, create a folder or upload files, choose upload files, then browse to the Gcode that you have created and upload it to the SD card. Boom. Bob’s your uncle.
I flashed the Jackpot to V3.9.1 however I can’t get the UI to look like it did.
I’m getting confused between the webui, the LR2/LR3 UI. What was installed on it when I got it? I just want it to go back to that.
Can one of you please walk me through how to upload the necessary files to the ESP32 and what I need to do?
Is it literally as simple as uploading all of the files contained in the github version (2/3)? I went with V3, thinking it was the latest but I think my jackpot may have come with V2 loaded. The problem I was having was the index.html file wouldn’t complete its upload, unless it takes a VERY long time, it appears to hang
