Firstly I am based in the UK, this unfortunately pretty much precludes me from purchasing items directly from SeeMeCNC due to shipping costs and import duties only mentioning this so as to explain my Heath Robinson'ish setup.
So the peek hotend gave up the ghost, I purchased an el cheepo E3D V6 clone (For testing), printed a top retaining bracket, to replace the melamine one that the peek hot end secured to.
Once v6 hotend secured and new cabling routed I found a slight misalignment at the 0.4 nozzle and bed center.
Calibrated Z position and then ran through towers. This showed varying heights which I then painstakingly ironed out with the home screws on the offending axis(s).
But here is the problem while printing a cube 10 by 10 by 10 mm:
The X axis is pretty darn good ~ 10 to 40 microns deviation ( 0.01 - 0.04 mm)
But the Y axis is way off 500 to 700 microns (0.5 - 0.7 mm )
I also printed a 20x20x20 mm box and am seeing a similar deviation on the Y axis. 500 to 700 microns (0.5 - 0.7 mm )
Could someone please give me some pointers as to how to resolve this issue as thus far I have been scouting the interweb but nothing has resolved this.
This Orion is running 0.91S version of Repetier and employs the older melamine based skates, not the newer plastic cheapskates and ball joint arms. Did go to purchase them from SeeMeCNC but the shipping was like $60+ dollars not including import duties (HMRC the robbing B&$£&rd$) which makes the delivery and taxes more expensive than the parts

All the Best,
