Aluminium Extrusion Router Build

**NFryer** · 12-11-2018

I think that I've got the control cabinet wiring sorted out. I'm using a Schmersal safety relay which can be triggered by the main E-Stop button, the stepper driver fault output, the inverter fault output and the E-Stop button on the MPG hand controller that I've got. Once triggered the signal is sent to the CSMIO controller, the stepper drivers are disabled and the inverter stops the spindle using the E-Stop ramp. A off time delay relay is used to allow the inverter to stop the spindle and then enable the STO function which disables the output of the inverter. To reset the stepper drivers I've included a switch in the PSU contactor coil circuit. A switch is used to also enable the inverter STO function when changing spindle bits to make sure there is no chance of the spindle starting. I intend to mount the control cabinet on the machine frame using some Paulstra anti vibration mounts. Also on the machine I will include a small control panel, with start, stop, pause, home and auto tool measurement buttons, along with green, red and yellow LED's for the start,stop and pause buttons.

First let me congratulate on an amazing build. Its amazing what many do with aluminium, basic hand tools and a little patience. I started designing a build (was all steel) but after spending a few hours with Clive its back to the drawing board for some re-jigging about. I thought I would need a mill to turn out the stuff many have done, but you have shown that's not the case, well done.

I was trying to work out some measurements from your design - is the gantry 90 x 45 heavy - and did you do an L shape pattern ? I think that's what quite a few have done - Heavy-Aluminium-Profile

I see you have put aluminium on the top of the x and y axis - is that 20mm cast aluminium?

Many thanks - and sorry for all the questions - I am just learning.

Hello Freyer

i am new here and i saw your design and my question is about the x axle moving by two ball bearing and one motor joined together.
does this work ?

Hi Frank, you can use a single motor and a long belt to connect the two x axis ballscrews together, check out the build log of Joe Harris, he did it that way. I decided on using two separate motors to drive the x axis ballscrews. Either way works.

Hi everyone, I've got a couple of updates on my router build. The main frame is completely finished, with the addition of an extra extrusion on the bottom to make a control box mount. I've just got to have a move around on the garage to get it into its final resting place. For the control box mount I've also made a couple of simple plates which bolt to the 2 extrusions and have an anti vibration mount on them. To finish this off I just have to make a couple of top mounts. I've also made a couple of mounts to fasten the x axis drag chain channel to the main frame.

Just a little follow up to my last post, I've fastened a couple of aluminium pieces to the underside of the control box and I have made a couple of top mounts for it as well.

I've also made a good start on the control panel which goes in the control box, most of the power wiring is complete. I think this is turning into a small project all of its own.

Looking great Nick 👍
I seem to remember my control box taking much longer than expected too !

A massive well done on the build! I was on the point of giving up on my build due to lack of tools to finish the job properly, but this thread has given me new inspiration! Can't wait to see videos of yours running! Keep up the good work!
