My experiences with my kit from ATI:
Ordered kit on 2/9, per web page expected delivery is in March. No order acknowledgement from ATI.
Kit arrived on 3/11 right on time. I have the following problems with the kit:
1. missing part #20 16 M5 x 30 BHCS (Emailed ATI, says they will mail replacement, the bolts arrived today.
2. part #6, Makerslide 420mm rail, has a dent in the linear rail in a bad spot (Contacted ATI, they asked me to send a picture of the damage, and I did, but have heard no response. I advised ATI that I have had a total of 6 CNC machines, so I have some experience, and I am sure the dent will affect the quality of the print.) No new rail arrived with the bolts above.
3. The belt clamps are the old version that requires a double layer of belt to hold the continuous belt supplied.
4. the Delran lift blocks that raise and lower the X axis on the gantry have holes too large for the 8mm rod, and they are not threaded so couldn’t lift the rod in any case. (My mistake, the way the lift blocks work is changed, and there are new parts in the kit that are threaded. They new parts are not mentioned in the build instructions that I could find, but they are mentioned in the forum)
5. My four plates are of two different colors, with only the extruder carriage being deeply anodized, the other three are washed out light blue, probably from the previous run. If you go to my build log here:
http://www.k4mg.com/Hobbies/CNC/Ord_Bot_Hadron_Build_Log.htmYou can see the difference in the picture of the completed axis.
I plan to finish my build with the defective rail, document further that it doesn't work satisfactorily, and ask again for a replacement rail.
Update: 4-19-2013 took a long to finish the build due to a defective Ramps board, see the posts about that problem. Anyway, within next week I will do some calibrating and printing and see if the dent affects the print quality.
