    Thanks Chris and Erick, I was uncertain about how well the touch plate would work, I thought I may have to weigh it down, however it's amazing, the router bit rises and hits the plate, there is some momentum in the router, especially if the lift has got up to full raise speed, so router mass and obviously the touch has to register in software and the software has to halt the router lift all contribute to a 1 or 2 mm overshoot and it lifts the very light touch plate accordingly, however I coded the lift stepper to micro step back until the touch plate is no longer touching, then it micro steps up to just kiss the plate, I was seriously impressed that I got the code for that 100% right first time. It takes about 1.5 second to do all the final micro stepping of the lift motor to set bit home accurately and it was just impressive to see that and also hear it do that so fast.

    Well, off to house duties now and cooking the evening meal.

    Some final thoughts and observations.

    I had a chance to do more work at the router table with six timber chair seats, during the process I happened to be watching the dust disappearing into the cabinet and towards the rear dust port, I wondered why I was seeing some swirling and deflection about 50 mm behind the bit, almost like water flowing around an invisible rock in it's path, turns out I had forgotten to refit a special deflection shield I had made to stop the Router motors internal fan from screwing with the dust extraction flow. Most router motors blow quite high volume and pressure air outwards and upwards (looking from the base plate.) This opposes table dust extraction flow, and on a smaller dust extraction system it will cause dust to be scattered all around the under table housing and in some cases even force dust back up out of the table. Fitted the deflection plate and air flow is neat and straight again.

    An update on Noise induced glitches. Way back when I first started using these two DROs in this table, I did everything I could at the time to stop glitches from the router motor and switch gear from causing a sudden jump in the DRO position display, a jump that was often permanent and forced me to reset the DRO. I thought I had it beat but it always came back randomly. Fast forward to now, I'm using the same two DRO's but without the OEM head units, the main problem unit was the Router height DRO as its Scale sender is mounted right next to the Router.

    So, I'm using the same Scale senders, in the same position next to the router motor, with the same switch gear and the same 5 volt supply and mains wiring. There has not been a single glitch under any condition with this new installation, there is lot more cabling in this system running to the Micro controller display, apart from running everything the Micro also replaces the OEM head units. If anything, it should be more of a problem, but it's not, the only conclusion I can come to is that the culprit was the OEM head display controllers. I thought it was the Scale slides themselves. This is a big plus as that problem was always in the back of my mind with this build. At Router power on or off, the OEM head units always gave a jump in readings, but usually returned to the correct display value, my controller does not even flinch, and my read speed and display update speed is way faster that the OEM head units, if there was a glitch I'd see it. There is not one negative thing I can pick in this system so far, everything has exceed my initial expectations and that almost NEVER happens.

    It's been great just reading all the ins and outs along the way, you have left absolutely nothing out, I wouldn't have the patience nor the skills to complete such a task, now off to work and enjoy your project.

    Thanks, I think I've had enough automation for a while, got a few woodworking jobs to do at the router table and looking forward to putting the revamped table to more work. Some overdue workshop rearrangements to finish as well. I've documented everything and just need to finish the circuits and connection layouts along with a workshop manual, something I always do on my finished projects. It's been a lot of fun to get from an idea to a working machine.

    One thing I should add, the Skill and patience were mainly in the programming, to actually build a unit is reality quite simple now that we know that the layout works. The fence drive could be made in one day, the router lift actually took 2 days but I'm modifying a dam plunge router to mount in a way that it was not designed for. A spindle motor would be a dream to do, it really is a simple router lift, and low cost, especially if you don't want to automate it. This router table design all started with a desire to redesign router table dust extraction for ZERO dust, I achieved that, and this addition just makes that design even better.

    Cheer to all.

    I want to thank Mike for his efforts you can all see here as it was me who asked him to continue with the project from where he originally left it. The work he has done here can be used on other machines as well, a motorised rip fence on a saw anyone? Those mitre lock bits now only need to be set up once and you will always be able to put the bit in and call up the settings every time you want to use them. Do you do jobs that get repeated every so often, store the settings and save time when the job has to be done next time. By the time this table is built the expense would be line ball with a good lift and router and it will do a far better job. It will be far cheaper than buying a router table with lift and router though I do understand that those who go that way want the complete kit and not the hassle of building it.

    Fantastic work! I particularly like your dust collection innovations. Will be checking out the follow-up threads.
    Thank you!

    There is a wrinkle on the dust extraction in my table build and all will be revealed shortly. It is aimed at reducing some of the noise which Mike says is quite loud on his.
