    I already fixed the problems, cut the bolt down to size with a cutoff wheel and tapped the hole that didn't have threads. I have the tools to do that sort of stuff, but not everyone who buys one of their kits might (especially if they are buying mainly for woodworking). I let them know because it is an issue that they should attend to.

    It's been a while since my last update - was waiting on the z-axis to ship. Ultimately received that and finished the assembly yesterday. Today I put in the power drop - had been waiting to see exactly where things lined up. I wanted to do a straight drop from the ceiling.

    One really weird thing I found was that the 220v plug had not been wired correctly. I've standardized on the 30A twist-lock connectors so noticed when I was switching over from the 20A to the 30A.

    The 220 plug from CNC Router Parts wasn't wired correctly? What was wrong so I can check mine. Your machine looks good.

    How far away from the table do you think you could mount the control & VFD cabinets? I'd like to mount mine on the back wall of my shop so I can mount my vacuum table controls on the side
    so the end can be left open for storage.

    Post when you get it set up & running.

    Thanks in advance

    How do you wire a 220V plug incorrectly? There are only two interchangeable hot legs.

    yeah you would think so, right? What happened was the wire was inserted and then the post was torqued counter clockwise, so that instead of the wires being clamped between two conductors, they were pressed out against the housing.

    Really weird, never would have found it except I run all 30A connectors so was changing over. When I tried to unscrew the lug it was still connected, so had to "tighten" it (turn the lug screws clockwise) to get them to release.

    The cable are pretty long - and there isn't a lot of magic to them. I didn't extend any of the motor controls, but for the limit switches I just cut the cable and spliced in some more where needed. I ordered some 1x2 conduit and 3/4 split loom that I'm going to use to tidy things up a bit. It's a well made kit that I have been quite pleased with. I'm just calling out the few issues I've experienced so that anyone expecting it to be pure "plug and play" has the right expectations. If I didn't already have a metric thread tap and die set I might not be as happy...

    Other than the tools they recommend, I found a caliper and my Bosch laser distance measure be very useful.

    Default Re: CNCRP Pro4x8 - power connection and dust collection

    It's been a couple of weeks since I last updated my build - work and life have slowed me down a bit, but I've made some good progress.

    I'm pleased with the way my power connection worked out. I wanted 4 sided access to the router, and was not willing to have a power cable as a trip hazard in the aisleways. So I had to drop it from the ceiling - which also gave a great place to mount the e-stop.

    Because it is a kit, CNCRP leaves certain choices up to the purchaser. To that end, I've been working on
    1. Dust collection
    2. Cable Management, and
    3. Sensor guards

    For dust collection, I ran 4" rigid drain pipe (Lowe's) from my harbor fright dust collector (unmodified at this point), up and over the table and then dropped down with flex cable to another piece of drain pipe attached to the z-axis. For the dust shoe I used the $36 "Double Door Spindle Dust Shoe Cover Cleaner for CNC Router Engraving Milling Machine (80mm)" from amazon.com.

    Default Re: CNCRP Pro4x8 cable management

    Cable Management - I don't like having unprotected cables, I'm much happier if they are either in a cableway or protected by split loom. I bought 100' of 3/4 split loom from amazon, along with 25' of 2150 cableway off of amazon for $95, and also got the z-axis kit from CNCRP.

    Here's the z-axis -

    The back side of the gantry...

    And a good example of using split loom and cableway for the run to the y-axis max limit switch.

    And then here's where the whole mess comes together!

    Default Re: CNCRP Pro4x8 - sensor guards

    The limit switches are at the very ends of the travel for the z, y, and z axis.... so by definition they stick out. A ways! I'm pretty sure that it wouldn't take me much time to damage one of the sensors (or myself) as I traipse around the shop. So I fabbed up some sensor guards from aluminum stock I had lying around (I work with a company that lets me rummage through their drop pile).

    Using existing holes / hardware, nothing is required except for the scrap aluminum.

    I made guards for the gantry and the table, but not for the z-axis. If I manage to bump that one something has already gone badly wrong with my day!

    Gantry:

    Looks great, and thanks for all the info. I will be following your build as I am deciding on the split spindle plasma table. Keep up the good work

    Thanks, there are a number of good videos on the "standard" build that I would not attempt to replicate. I thought it could be more useful to discuss the mods that I made. If different images or details would be useful I am happy to go into excruciating detail.
