With the machine switched off (or with the steppers disengaged), can you easily push the bed backwards and forwards through its entire travel? Are there any stiff spots? Is the belt nice and tight (but not murder tight)?

Hi AdeV,
Thanks for the reply.
I use Cura 4.4.0 and not sure if I am staying with it as recently its started doing weird things which even show up in thre preview.
Both axes move nice a smoothly. In a previous post[#18] I mentioned how I realised the belts had stretch a bit (like 0.1mm) and that I had adjusted them

Hi Ben,
Thanks for the reply. The bed clips will pass under the print head even at Z = 0. This "SHIFT" in Y happened at about Z = 6mm
No way am I giving up. I will mod it to the end of the earth if necessary!

Did you try re-slicing the part? Did you try printing a different part? And if you did - did it make any difference? If it didn't make any difference, then look at your machine for problems. Otherwise look at the slicing software.
Like I said in my post on the 23rd, this would periodically happen to me when I was using Slic3r, or the Prusa version of Slic3r. The first time it happened I was also wondering WTF happened to this piece of crap now? When I couldn't find anything wrong with my printer, I tried re-slicing the part - printed with no problems. After that, when a part started screwing up the first thing I did was re-slice the part. If that didn't fix the problem, THEN I started looking at the printer.
I don't remember now which axis was shifted on my machine, and that's not just a "Senior Moment" type of thing, I haven't used Slic3r for close to 2 years. Don't get me wrong, Slic3r and Cura are both good slicing packages. But until something better comes along though, I'm going to stick with using Simplify3D.

I went back to Cura where the 8 models were. Removed all but two (the coolling towers and the big dome).
Moved them to a more frontal position on the bed and re-sliced.
Result:
Perfect Prints.
Latest with Cura is that it managed to put 2, 1 mm support structures ie very skinny thin lattice, across the middle of a Panda bear that certainly didn't need
Re-sliced and no problem!!

Thanks for every ones help.
Now I know why people say" Buy a simple printer and learn!!, 3d printing at our level is a hobby and not a production tool"
Back to school via Parcel Motel to pick up latest upgrades and filaments!
Cheers
Will
