The CR10 has a single Z axis leadscrew and I have no issue with this it really produces superb prints. From an engineering point of view a better idea would be to have a leadscrew at both ends. There is an upgrade kit available which uses a second stepper motor but I understand these can get out of sync when power is switched off and on and the bed must be re leveled every time.
My solution links the screws with a toothed belt and is driven by the existing single stepper. It cannot get out of sync.
All the parts cost less that £12.00 ( US $16.00) including delivery!
There is a bit of metalwork involved but you only need a saw. file and drill. If you really cannot do metalwork I have designed a printed bracket with the same dimensions. Be warned though this has not been tried out but it should be OK.
Parts needed include
600mm leadscrew and nut https://goo.gl/fM8znL
GT2 Aluminum timing belt pulley 36 teeth : https://goo.gl/hv9dVU ( 2 required) Make sure you order the 36 tooth pulley.
The 36 tooth pulley does not seem to be available from the above link anymore. Try Ebay or the printed version by Airfoxa380 https://www.thingiverse.com/thing:2611415
GT2 852mm Timing Belt: https://goo.gl/iXa4sv ( be sure to get the correct length)
Flexible Shaft Coupling: https://goo.gl/qfUhEe
Beware of ordering the leadscrew form other than the link given. There are 2 forms of 8mm leadscrew available.
One is a 4 start thread that gives a 8mm travel for one turn, the other is single start that would move the nut 2mm per turn.
The details are not given very clearly on some sites. I made the mistake and ordered the wrong one to start with.
Some people have said the printed bracket fits and others say the fixing holes are too close together. I have uploaded another file which has a slot so should fit OK.
No support was needed for the printed bracket. Note the models need rotating before printing.
LH bearing retainer STL dimension corrected.
