hello again smiler
could you answer a few questions,hope i'm not boring you with these:confused:
in pictures is the shaft under gantry driving pinions under main frame,if so how did you eliminate backlash etc.
i have s/h racks would they be accurate working with alloy? or are ball screws better?
what speed can gantry move on main frame?
i was going to run roller bearings mounted on angle iron on my alloy frame from stair lift(i think)instead of linear rail as i have low budget.what do you think:question:
P.S more pics please as one of the best builds i've seen then i'll stop anoying you:naughty:

That certainly give me a boost of confidence and enough to persuade me to stay in the UK for buying a board, the optoport it is. I wasnt to keen on buying one from America anyway, everytime I have bought something abroad recently I have been caught out by the import taxes.
Thanks for this advice, I was just told that you cannot beat the reliability of the proximity switches, but I had also heard from a few others, including you now, that they may not be as accurate as I want them to be.
Them main reason I wanted to use them was for their reliability and supposed accuracy. I will stick with my microswitches for the time being. I may look into magnetic, vane type switches. Our 5axis router at Uni uses these magnetic switches which appear to be very accurate and have certainly been reliable.
Thanks, just out of interest more than anything else.

I have found the photos in your gallery, do you have any more (of the build)? ... I am just starting to collect some bits for the same machine you have built, but like you I am not going to use timber.
What material did you use to mount the racks on? also I assume you used Aluminium for the Y axis side plates, did you stick with David Steeles' bearing choices?
Oh and did you ?... Ummm ... did you also? ... I'll shut up now.Tim G-C

I like your build and want to use some of your ideas, particularly like the way you have mounted the spindle. I took my router apart this morning and designed a support plate etc, looks like I didn't need to, a couple of rail clamps will do perfectly well.
Don't want to sound like a divvy, where do I find your gallery pics.
