HaItllNeverWork

Thanks for that. I guessed as much. The control circuitry should work all right I'm thinking maybe just a high power buffer on the end of it to power the steppers. I'm at a bit of a loss as to how to calculate what size stepper I'd need. I have access to some that are 3.1A per phase max 70 V but can't seem to find anything similar on the net to gauge if this is big enough or not. I'm not too fussy about the speed of cut Ie if need be I can do multi passes. I don't need to cut the ply in one go. By lead screw do you mean a proper machined screw or a piece of say M10 threaded rod. I'm obviously hoping the threaded rod will be ok but slighly worried about sag or twist over the length. I like the look and the reports on this project and the fact it interfaces directly with dnacam or something similar is just what I'm after.

I'm glad to see this project still has followers. I've read the whole site and felt a little disappointed to near the end and see posts like the main chip is no longer made. Still I'll have a go and try and find one. My Project = I want to make a wood cutting router table to cut up to 5mm ply but be able to cut 8' by 4' sheets (probably a little bigger than the average project posted on here). I'm thinking of directly coupling steppers on the end of threaded bar to move a trolley around that has the router mounted on it. Any suggestions as to what size steppers I'd need for this or what I could use as guides to keep it accurate. I envisage an accuracy of 0.1 of a mm to be more than enough. Any plans anyone knows about on the net I could get inspiration from? Anyway excellent site...Thanks.
