That is a question that you need to ask Richard. Having said that it is a part that you can easly find on ebay.

What about the stepper motor? does it go on top of the printer? if it does I am not sure how it will work You should have three big stepper motors (those boxlike forms on top in the picture) I cannot see on parts picture. As You can see on Sum picture, they go on top. Unfortunately I do not see Ballscrews, Alu Profiles, plates and many other vital things. Is that all You got that is on picture? I hope not........

When the cog is made.. Cutting off the piece from the bar that it is made from. .will raise a burr...fine metal edge.. across the hole the motor shaft is ment to fit into. Simularly when the screw thread for the grub screw is made ..the tool breaks through into the hole..thus if left unfinished these are sufficient to "block" the hopefully close fitting shaft to cog fit.
Such a bur might not be visible ..but might show up as you have observed.... Find drill of same size as motor shaft and push it through..by hand..held in drill chuck by all means but just to push the burr out...not over drill...also check motor for same

Hi, Thanks for the info The hole was too small, in the end I used a drill bit to expand the hole slightly. Now it's a tight fit (mentioned this to Richard who is going to look into it), guessing just a faulty cog. Below is what I've done so far today with some e-mail help from Richard.

Hi Burning, interesting blog read. I've pretty much built the structure, just waiting for the manual now from Richard so I can get the rest finished and get printing.

Ok, so the construction part is finished (although I have quite a few washers / screws spare!). Now onto the electronics. Sadly no manual yet and have asked Richard for any electronic guides but does anyone know if any deltas use the same boards etc?

Hello Jon, Here are some informations, I hope some of them will help you. Main site : reprap.org/wiki/RostockThe Marlin Firmware : github.com/jcrocholl/MarlinI speek french (and my english is bad enough), so this was very helpful for me : lesinventionsdenicolas.blogspot.be/2013/10/liste-des-tutoriaux-utiles-pour.htmlI am not sure I do the things the right way, I only tried to find the best fits as I think you also do. I chose the layout of the elements to keep it clean, I don't know how effective it will be when working. As you see, I added a protection box for electronics and a heath bed (mk2) with its separate power supply (Sumpod one wasn't already availlable when I ordered my Delta). Now the device responds to g-code commands (home - endstops status ...) I still have to calibrate the delta and adjust the firmware parameters (marlin configuration.h) I do not currently going forward at now because I am waiting for 3 shaft couplers to replace the current ones : www.aliexpress.com/snapshot/6422384806.html?orderId=65222476188726I decided this because there is a difference in strength between the three axes and I don't want to damage the axes and the steppers.
