    My 48" X 48" CNC Router Table

    Ordered some bigger drag-chains for the machine wiring and air tubes, so no more zip-tied to the outside of the too-small chains. next will be figuring out how to mount them. on the X and Y axis, i need to make some chain trays to support the chains. can be done with just aluminum trim-coil. the...

    Arduino/MQTT Home Assistant workshop controller

    there is a way to have switches, with only one switch and the SSR, but it requires a transistor, and two resistors for every switch, but it can be done with a central switch panel. ...or i can have a separate board in the case for the switching to take place. then i only need 3 wires. for the...

    My 48" X 48" CNC Router Table

    thinking of moving the tool sensor to the back of the machine, out of the way, leaving tool slot #1 open for manual changes, and keeping the tool sensor safe and out of the way. i want to put it in a spot where the laser can also use it, to make sure it stays in focus. i can measure the laser...

    My 48" X 48" CNC Router Table

    for on-machine cable looming, i am going to try cable lacing. it looks easy, and has a neat and clean appearance when done. only places i have to worry about are up on the Z axis, along the X axis, and the tail off the Y axis. i can loom other exposed wires too. like the wires leading to the...

    Arduino/MQTT Home Assistant workshop controller

    Re-working the controller, using the code scavenged from what was my MQTT Camper controller, as it is better. https://github.com/travis-farmer/ardmega_camper_MQTT now supports dual temp settings for the equipment closet. that way i can set the heat to 40F as shown, and the cooling fan at 75F...

    My Shop Notes

    I have solved how not to have smoke detectors in my shop. due to dust and laser smoke, they would go off all the time. but i can use a temperature alarm! if the temp rises above, say 130F, set off the alarm!

    What my Autism is to me

    the job prospects are not panning out, as i keep getting shot down at every turn. it is looking like my plan of making my way with my CNC machine is going to be my only way. i have some ideas, but i am not posting them here as web skimmers look at my pages frequently for information. just know...

    My 48" X 48" CNC Router Table

    if i run cables from the logic box to the control pendant console from the 7i72, i can power the LED button lights to show active toggles, like "pause". will be handy so i know when to hit the "resume" for example. when i re-do the wiring, i can re-use the DB-25 cable for this task. may need...

    My Shop Notes

    the strapping can be secured to the pipe frame with either angle steel bracing, and sheet-metal screws, or suspended with metal strapping and sheet-metal screws. the strapping would be doubled over at the end to prevent sharp edges against the tent surface. i would prefer to secure angle steel...

    My Shop Notes

    thinking about a warm closet in my shop. an insulated closet that i can put the alarm and network electronics into, and place a regulated space heater, or a baseboard electric heat unit in there. as it is the electronics closet, i could put a smoke detector in there, as i would hope no dust...

    My 48" X 48" CNC Router Table

    so, if i have battery backup for the CNC computer... what about the machine? may be a good use for my Off-Grid experiments. i could build a battery backup for the machine logic. i could set it up to maintain off of solar/wind power, and when i am using it, boost it with an AC to DC...

    My 48" X 48" CNC Router Table

    just happened to think as i posted just now... the laser air will want to come on when the CNC is running, just to keep the dust from clogging the port. i don't think it uses much air. the air blower for the spindle could even come from a small blower fan, to save on shop air. like a CPAP style...

    My 48" X 48" CNC Router Table

    been thinking about the dust shoe... and i wonder if the shoe and lift would be too much for the Z axis to lift up. the spindle alone is quite heavy, and needs a brake. here is a thought, and it is just that... a thought. what if i make a dust enclosure over the whole machine? if i have a rubber...

    My 48" X 48" CNC Router Table

    at some point i will need to experiment with a dust shoe system. something that will not get in the way of the tool changer. i need some sort of dust shoe elevator, so that during tool changes, the shoe is up and out of the way. but when it is needed, it floats down to the wood surface, or a...

    My Shop Notes

    in my bedroom i have a 2 foot X 8 foot counter i would like out in my shop as a work bench/desk. i can make it rugged, but also so a chair can roll under. if i make it the right height, my CNC computer thing can roll under it and the monitor and keyboard can stick out for use. just an idea... it...

    My Shop Notes

    for minimal insulation, i can use that thermal bubble-wrap https://www.amazon.com/dp/B07G64N67F/ for radiant heat thermal barriers. at least then i can have heat and A/C in my shop. the attic will need to be partitioned off and vented (power vented?) to prevent heat build-up in the summer. in...

    My 48" X 48" CNC Router Table

    a relay pin can be referenced by it's id, "RLY025-34", on the wire sheet start and end. i want to label connectors somehow, too. so the spindle power connector could be "CON-SPND-P", or similar. the Mesa connections will be as previously described, so as to not be confusing with connectors. or...

    My 48" X 48" CNC Router Table

    I have decided the master book will be a spreadsheet. i want at least the following fields: Wire Sheet ID = non-retiring numeric ID number. so of wire 030 is replaced the new wire MUST be 030, and the spreadsheet color code changed if needed to reflect the new wire color. COLOR = color of the...

    My 48" X 48" CNC Router Table

    the "roof" on top will be removable, as it will serve as the top raceway. the top raceway will route wires from logic to relays, and logic to machine. the bottom raceway will be for power wires to logic, and power to junction to the machine. the fuses will all be in one spot, in back of the...
