I had a problem with the bearing nuts on the X-Axis coming loose and creating a lot of backlash so i took the nuts that came with the ballscrew and drilled and tapped them 4-40 and put set screws in them. there not coming loose anytime soon. Also with the zero backlash couplers this thing is super accurate!!!!!
 
it all just keeps getting better, an adjustment here a little tuning and pretty soon you have a really nice machine you can depend on for years of fun.
nice job mgp

hello MGP and Jump4,

great looking job there.. i have followed hasses build and have my sheen up and running also. but have a backlash probolem. i'm using bigger motors and drivers, with a c11 breakout board the drivers are 5056D. and the largest motors in the 23 class.

i know way over power for this little sheen, but i have a bigger project that things might migrate to down the road.

where did u find the couplers?? i am thinking that might help some here. my x axis is set with 0.018 back lash and Y axis is now at 0.022 but still i get y axis lost movement on turnaround moves..

also where did u find the larger tabels???

would love to incorperate them into my sheen.

hello
thanks for your comments
mgp has been going to school and hasnt been here for a while so i will answer you. the couplers are off ebay but make sure you type zero backlash or anti backlash to search for them. they need to be a bigger diameter than 1". lovejoy couplers wont work well. if you have your gibs too tight it will cause the couplers to flex also. if you have bearings on the leadscrew check the preload it may be too loose. the larger base came from littlemachineshop.com . dont try to adjust to much backlash out it will cause binding once the machine warms up a couple thousands is wanted, just check and set mach3 to compensate for the backlash, if a small mill like these will cut a circle to within a thousand or two of round that is pretty good. if i need more accuracy than 2 thousands i use a boring head to finish the hole. since most parts only require accuracy in a few key areas it is better and faster to make the part with extra tolerance in the key areas and come back and fine tune the part for the required fit.

The larger table is a SX2 table, maybe littlemachineshop.com can help you with that. I have seen it availible before, but for the life of me, I can not seem to be able to find the base and table by it's self as an item to be had for sale.

I had to ream the couplers to fit my shafts but was not a problem at all. Dont know if your interested but i have my X-Y Table that came with my X2 but shipping to Alaska would be painful.
 
I have read completely through this thread. I want to say to Steve and MPG, that this thread is great and is way better than any of the threads that I have read over on CNCzone. Over there, I get lost with all of the mumbo jumbo and knowledge boasting. You guys made it a lil easier to understand by just keeping it to the nuts and bolts, instead of getting off into the deep end of TMI. I want to say thank you for that. I already feel more comphy about maybe doing a conversion. Over on the other site, I never felt like I was going to be able to comprehend everything that I was reading.. heck I even tried to find a CNC for Dummies! There is something for the KISS system!
