    Well counted my chickens that time. When i looked closley at the first cutting it seemed to be alright but not perfect. When I tried to use the machine again it kept locking up. I assumed it was ball nut, bearing housings, bent screws. So I have spent hours moving, drilling stripping and rebuilding with varing amounts of success but never really solving the probleml. At one time I thought i had it beat but when trying to cut a design whole sections were out of alignment. I had Michael round to help plus a retired cnc fitter all to no avail.
    Today I decided to go back to basics and put up the dti and found I was losing steps on just one of my x drives. Chatting to dean I checked all the wiring and swapped the step settings from 1/8 to 1/4. The problem got worse and it would jam after 150mm. if I loosened the motor mounting nuts it worked. I could hear a ringing and thought nothing of it. Swapped the two motors and then neither would work properly. Finally I thought I would take note of deans advice and looked at the steps again. I changed it to 1/5 and instantly everything was just dandy.

    I have put the machine back together and cut a new sign. It is so much better in quality and cleanness of cut.

    All thats left to do is get the probe plate working but that will have to wait until another day.

    Built my self a dust shoe over the weekend as I am at last fed up with holding the hose next to the work. I wanted one that 'floated' so that its height was not governed by the spindle. Mark 1 used screws to guide it and was a failure. So I decided to use bearings. These are inline skate bearings from another project. The brush is from a letter box draught excluder.
    I have a video which shows that it works really well.

    Still cannot get the touch plate to work!!!

    The sign at the end is my first attempt at something a little more complicated.

    Well that about it. I now have the touch plate working and from here on in its just tidying and tweaking. I have cut some signs and other test pieces and I am very happy with the final product. This probably is the end of the build log so a big thanks to all of you who helped me complete this project.
    Any further updates or info I will just make separate posts.
