I am eagerly following along with the directions as new steps get published. So far building this has been a lot of fun (and it’s been cool to realize the clever tricks after I’ve done something the hard way, i.e. screwing together braces + XZ plates with a flexi screw thing that there are holes in the YZ plates to make it easier!)
I do have one question - this is meant to be a full-sheet CNC, so I don’t currently own a table large enough to host it. I was planning to build the parametric table from the forums here, but how do I get started? Can I just run the CNC on the ground here? It seems like as long as I have a hard surface for the wheels to run on / Y rail attached to, and some way of keeping the work material fixed in relation to the rails, it should be fine. But I was wondering if there was something I am missing.
Should be able to run CNC on the ground providing spacing of the Y Slats is fixed and ‘rigid enough’ for the material and slower speeds you’re doing during Bootstrap mode. Have seen people (i.e. fellow Maslow owners) use material that stops rugs from slipping underneath their garage floor spoilboard (e.g high density foam, particle board, MDF, etc…). Large and heavy enough work piece plus anti rug slip might be good enough(?). That said, creating a minimally viable cutting surface would be better…
Personally built a minimum viable Sled on the garage floor. My thinking was it’d eventually get some decent legs and become a table. Reality ended up being it’s mounted mostly unused up against a wall, and am using a less space hogging bar height bench sized for quarter sheets instead.
Assembled my rolling sled on a ladder instead of garage floor to help get closer to True Level.
Well, I had it moving in two directions! Then I took the ESP out of the Jackpot to re flash it (messed up the password and couldn’t connect) and put it back in backwards. It actually smoked!
So… guess this project is on ice while the replacement comes
So sorry to hear that. I think you can actually re-flash it without taking it out of the Jackpot. I have “re-applied” firmware to mine multiple times without taking it out of the Jackpot.
I totally could have. But the jackpot is wired into the machine in my workshop downstairs, my desktop is upstairs, and my laptop is dead. So… laziness won, and bit me in the butt this time!
I’ve got about a dozen of the ESP32s around my house to run lights, manage A/C and blinds, and various other random things. Normally I have them set up to update themselves and my own ones have a button that resets their Wi-Fi setup to AP mode with a preset password for this exact problem! I just hadn’t quite gotten there yet with the Jackpot.
Yes, if you turn off VMOT power to the jackpot and attach a USB cable to the ESP-32, you can completely flash the ESP-32 all the way from erase using the native tools or the Web flasher.
EstlCAM was printing some probe instructions that were causing me trouble at the start (my machine would drive straight down until it bottomed out, looking for the contact!) Deleting those from my gcode got this working great.
I’ll be cutting the struts tomorrow and hopefully getting the table together this weekend. I couldn’t be more thrilled!!!
I’m looking at some of the alternative tools. I think both a drag knife and a laser would be fun to play with in addition to the router. Are there already pre-designed mounts for these?
I sat and watched it cut these for an hour with just the most insane grin on my face. How cool to go from reels of filament + some hardware to a fully functional robot.
So it’s all put together. Squaring tool a while to wrap my head around, but now that I did, I’ll try to put more details into the instructions. I sketched some pictures too which may help (at least the uninitiated like me.)
I’m starting with the parametric table from here on the forums. It took some false starts (see char marks, boyfriend made me buy a fire extinguisher after seeing those!) to get my machine dialed in, and crawling around on the floor to run this guy is a pain in the ass.
I am not sure how many need to tell you that is a bad idea!!! I forgot my program started with probe. 2 seconds in i had smoke!!! 2seconds! Sprinting leads to tripping and minutes!!! Attendance to this is mandatory, not optional! Do what you want, but none of us will support this. That is non compliance in my book.
Looks nice.
